Physio Cardio Lab Report Answers Essay

Our bodies have a unique way of establishing the ideal gradient flow. How does this flow happen? Consider a pipe. What is the physics behind the way water flows through it? All thanks to pressure gradient, a pipe’s fluid flow remains constant, moving whatever liquid through it to the other end.

Our bodies utilize a similar mechanism to ascertain fluids flow well. The pressure gradient supports this. This relies on the force of flow coming from either end of the pipe being the same. However, the pressure gradient is opposite to resistance, which depends on a pipe’s diameter or radius. Therefore, many factors come into play when moving fluids through a vessel. If everything falls into place, and the pressure is sufficient, then fluid flows, but the pressure and rate alters because of various factors.

Therefore, for the entire body’s fluids to flow well in any vessel, there ought to be an ideal pressure gradient to ascertain that blood flow distributes perfectly to other organs. Any blood vessel possesses a higher potential of passing more fluid. A small radius means less flow rate. Hence, the radius is the biggest determinant of the flow rate.

Based on my findings, any slight alteration to the vessel’s radius influences the flow rate. We noticed that whenever we altered the radius by expanding it, we saw more liquid flow and a tremendous flow rate. The opposite of the vessel is also true. These two variables are directly associated.

When one generates more space, they allow more room for liquid and increase flow rate, making it go a lot faster than if it were smaller. We started with a 1.5mm radius for the vessel and noticed a low flow rate. However, after a progressive increase from 2mm, 3mm, and subsequently to 5mm, the flow increased significantly that led us to the conclusion.How the Radius Influences Laminar Flow

Laminar flow is the movement of a viscous liquid. Each particle of the liquid possesses the same flow velocity but is in move differently relative to its neighboring zones of the vessel. When considering various factors determined from the test, it is evident that any alteration to the radius transforms laminar flow. Hence, the radius is undeviatingly related to laminar flow.

If a vessel possesses a small radius, more increased blood will be touching the walls. Therefore, the blood vessel will maintain less laminar flow, massively affecting the speed. However, when the blood vessel possesses a bigger radius whereby it is more dilated, there will be a better laminar flow.

Plot Linearity

What is the correlation among these determinants and mostly the flow? The chart symbolizes the bond connecting the radius and flow rate. The former is on the X-axis while the latter is on the Y-axis. The pupil was supposed to moderately add the radius of the vessel and plot the alteration. It is clear, as represented by the graph, that everything is linear, which suggests that a particular flow rate is undeviatingly associated with the vessel radius. It represents an increase in one variable makes the other increase.Comprehensive Replies to Inquiries for the Second Activity

Blood flow is affected by various factors, and stickiness is amongst the biggest. However, how does this stickiness arise? Blood possesses various proteins that move in any vessel. These are white blood cells, erythrocytes, and platelets. The presence of these elements that combine to create blood is the biggest contributor to viscosity. The moment that these blood plasma proteins meet when moving, they generate a flow resistance that makes viscosity. Therefore, the flow rate is affected by density in the vessel, but how does this happen?

Although my physio cardio lab report answers essay is not conclusive, the results will show exciting findings. Blood sliminess is just friction or stickiness: the stickier the fluid, the more extraordinary the rate of thickness. When you compare a fluid’s viscidity and flow rate, it will be apparent that they are inversely related. Therefore, any increase in blood viscidity amplifies the flow rate. The outlined diagram skillfully depicts how these variables are inversely related. An increase in stiffness makes the flow rate go down significantly, meaning less fluid.

What is the perfect representation of the numbers as portrayed by the blood flow against viscosity visualization mean? The diagram is an absolute visual representation of the inverse correlation. The constants of the analysis are apparent, and they are the radius, pressure, and range.

On the Y-axis, there is the flow rate, while blood thickness is on the X-axis. Therefore, when we increase blood stickiness, the flow rate diminishes hence the inverse correlation represented by the curve moving downwards. What other factors can affect the consistency of blood?

One of the common determinants that massively alter the blood’s viscosity is the polycythemia condition. This blood condition means that your body is producing more red blood cells than other plasma proteins. Hence, your blood will have a higher concentration of red blood cells. In our earlier findings, we figured out that increasing red blood cells make blood viscous.

The consequences even go further to switch the flow rate regarding the coherence has risen. What does this mean? If you are affected by blood polycythemia, you are going to lower your blood flow. Hence, polycythemia is inversely linked to the blood flow rate. What Other Factors Affect Blood Flow?

What possesses the most eminent probability of happening in a human’s body? A variation in radius or alteration of the measure of your blood vessel? It is hard for your blood vessel to adjust the scope, but it happens when we grow. During adulthood, the blood vessel cannot continue to grow. It indicates that the only change that can occur in your body is for the radius to increase or decrease depending on various changes happening in your body.

The only way that your body’s blood vessel length is going to happen is if you lose or gain significant weight. One of the ideal means of increasing the growing radius is via vasodilation. You can even smoothen the blood vessel muscle to alter the radius. Therefore, you can utilize various ways or strategies to increase your vessel’s radius, but the length is hard to change.

In case blood vessel length adjusts, in what way will the flow rate be affected? Of course, the alteration in it would create a profound influence on the flow rate. We tested its impact on the body’s liquid vessel in a controlled environment in the lab. The moment that you increase your blood vessel length, fluid experiences more friction or resistance.

This blood resistance makes it even harder for blood to flow smoothly, signifying there will be added viscidity. It represents a converse association between blood vessel distance and flow rate that means an increase in one leads to a reduction in the opposite. Based on the blood results, whenever we increase the blood vessel length, blood flow is significantly reduced.

Blood vessel radius creates the biggest difference and influence on human anatomy than an alteration in length because of various reasons. As you can see from the blood flow computation, blood flow is undeviatingly proportionate to the fourth power of the vessel radius. This way, massive modifications appear to the flow rate of blood whenever there is an alteration in the blood vessel radius.

It is evident that the more minute the radius, the higher the endurance and a decrease in the flow rate. The radius stands out as the most integral factor when seeking to conclude the impedance flow of blood in any vessel. Regardless of any slight changes happening on the radius, there is always a more considerable influence on the flow rate in the vessel, which is influenced by friction.

The experiment clearly shows that weight, whether a gain or loss has a massive effect on blood vessel length. Also, the only way that one can alter their blood vessel length is through changes in weight.

According to the experiment, any time that blood vessel length increases because of an increase in weight, resistance, or friction increases. And as evidenced by earlier results in the experiment, any increase in blood resistance reduces blood flow rate as they are inversely related. When someone is obese, they increase weight, meaning that they lengthen their blood vessel. As stated earlier, the change in the blood vessel’s length will cause more friction, which will decrease blood flow. Therefore, the flow rate in the vessel will be lower.

What Are The Different Effects of Pressure Fluctuations?

The pressure is an excellent determinant of the flow rate. Whenever pressure increases, your vessel flow rate also increases. This finding implies that the pair are undeviatingly proportionate. According to my prediction, which stated that pressure increase boosts the flow rate, the realities prove that I was accurate. The plot for tube radius, stickiness, and conduit length have considerable variations. Based on the graph outlining the correlation between pressure and flow rate, there is a direct connection.

It indicates that whenever we increase pressure, the flow rate hikes as well. The graph’s line is a straight one and sloping upwards. When looking at the map potting the tube breadth, the line was more curved but followed the same direction upwards. Therefore, any addition to the vessel radius raised the flow rate.

However, the thickness and flow rate produces a very different link as represented by the results. Any increase in viscosity by altering certain factors like the radius diminished flow rate considering there existed more hardness in the edges of the blood vessel. The test on tube length also showed an inverse relationship with the flow rate producing a downward slope.

Whenever tube length progressed, there was more opposition, minimizing the blood flow rate. Once I figured out that the radius is the most important determinant influencing the flow rate, I concluded that a pressure increase would increase blood flow. Therefore, they are undeviatingly comparable.

Is Pressure Alteration the Ideal Strategy to Control Blood Flow?

The blood pressure originates from the heart, and it is the primary organ pumping blood everywhere. Therefore, it is not a good idea to alter the pressure of blood transmitters to control the flow rate, as it will place more stress on the heart. It makes the heart change its force of contraction, which is not healthy whenever this happens.

Another reason why pressure alteration is not a proper method of controlling blood flow is that vessel requires sufficient time to adjust, including the massive arteries around the heart. They have to develop more tissue in their tunics so that they can easily accommodate the heart’s pressure and the sudden force change. The safest way of changing blood flow and controlling it is via changing the radius. The experiment gives sufficient evidence to support this claim, and it is better not to affect the heart.

In the test, the radius and resistance represented by viscosity and length were constants, while flow rate and pressure were variable. I used these figures to compute the increase in flow rate in ml/min/mm Hg. My starting figures for pressure was 25mm Hg and a flow rate of 35mm/min. Every time I increased the pressure by 25mm Hg, the flow rate altered by 35 mm each minute.

Right Flow Tube Radius and the Human Heart: How Do the Results Compare?

There is a direct link between the right flow pipe radius and flow rate, meaning the increase either makes the other increase as well. This happens because of lowering the viscosity. The left beaker depicts the area of the heart for pumping blood. The right represents the other side of the heart that delivers blood to other organs.

By what means does the heart counterbalance for alterations in flow rate to regulate the blood pressure? The heart is the primary human organ that regulates blood flow and force. Therefore, it compensates for any fluctuations in the flow rate by changing the stroke volume. When there’s a higher speed in a blood vessel, the heart rate hikes as it is the only way to balance this power. The vice versa is also true.

Activity Six: What Are the Results?

The Frank-Starling law clearly shows how our body’s blood flows within any vessel from the heart. Whenever the heart receives more blood, it stretches its capacity. Therefore, the heart elevates a more considerable amount of wood than it applied to extend the stroke volume. This harms the pump rate of the heart. The strength of your heart determines stroke volume.

The heart is a beautiful organ with incredible capabilities. Therefore, any time the heart alters the pump strength, the stroke volume varies as well. Intrinsic factors are affecting the heart and its stroke volume, which greatest determinants of cardiac output. Your blood flow in either vessel is undeviatingly comparative to cardiac output. Whenever stroke volume goes down, your heart rate’s rhythm increases to par with the cardiac output.

How Is the Heart Affected by Various Changes?

Peripheral resistance is an excellent factor in fluid movement. And it matters much when looking at the effect of the heart after adjusting the blood flow rate. The heart counteracts peripheral resistance by lowering blood resistance and via altering contraction force. Whenever this happens to the heart, it makes it easier to deal with afterload and blood’s viscosity.

Before embarking on the experiment, I predicted that developing the left flow conduit radius would massively affect blood flow into the right tube, mimicking the heart. Another result of my findings from the experiment is what happens when the pump and beaker’s force is the same. The valve will not open whenever this happens because of an insufficient driving force that cannot force fluid out. This result was contrary to my prediction.

It would be easier and more straightforward to change the heart rate when looking to alter blood flow. Although the lab outcomes have explicated that blood vessel radius is an excellent means to increase flow rate, I think exercise makes blood flow more as it makes the heart beat faster. Therefore, the heart rate creates a better ground for better blood movement.
