1. In your own words, describe how blood flows through veins and how blood flow relates to blood pressure. Then, give an example of a time when one might have irregular blood pressure and how this affects blood flow.
We learn from our biology class that blood flows through the veins due to the pumping action of the heart. So, when the heart performs its function of pumping blood through the arteries which uses pressure , there is a certain amount of resistance that small arterioles exert when receiving blood from the bigger arteries . This tension between the pressure of blood flow and the resistance of the arteries determines the blood pressure. Certain qualities of the arteries ( such as elasticity ) that carry the blood can influence blood pressure. The arteries can constrict (due to clogs caused by fatty deposits ) which increases the risk for high blood pressure, or it can simply dilate allow blood to flow normally . An irregular blood pressure can be caused by many factors such as : stress, lack of exercise, posture , and straining. Lack of sleep can contribute to low blood pressure which means that blood is not flowing as expected thereby reducing the energy of the body. On the contrary, high blood pressure causes too strain on other organs of the body that can result to injury or damage and produce metabolic disorders. Blood flow is critical since the blood is important in the distribution of oxygen as well as nutrients to the whole body, however, the key to a healthy living is moderation.

2. There are several special areas in the body where blood flows. Choose one special area and explain how this area could have an imbalance or irregularity.
Think about a time when you or someone you know experienced an imbalance in one of the special areas identified. What were the results of the imbalance and how did it affect the body’s overall function?
The left heart chamber is an important part of the circulatory system. This is where the blood is transported back after it has circulated all over the body. When blood pressure increases, there is a high probability that this organ would thicken. When the heart cannot accommodate the pressure , its ability to squeeze is impaired resulting to heart failure. According to the American Heart Organization, when Congestive Heart Failure (CHF) happens, the heart cannot pump enough blood to the other organs of the body. One of the major organs affected by this situation are the kidneys. As we all know, Kidneys play an important role in maintaining water and sodium balance in the body. When CHF happens, blood flows slowly to the kidneys thereby causing blood to back up in the veins, moreover, a high amount of sodium is retained in the body. This results to swelling or edema in certain parts of the body such as legs and ankles. However, this can also happen to the lungs when it accumulates fluids thereby causing shortness of breath especially when a person is lying down. The American Heart Association defined this condition as pulmonary edema which can be life threatening. Read More

Blood pressure

...?Blood pressure is a measure of tension exerted by blood against the walls of the arteries. It de s the force of ventricular contraction, the resistance within the arterioles and the capillaries and the volume and viscosity of blood. Accurate measurement of blood pressure in the presence of findings in the history and physical examination of a patient can bring to light a diagnosis that may pertain to any of the above factors. This is why measurement of blood pressure is an integral part of general as well as cardiovascular examination. There are several processes that control the blood...

High Blood Pressure Measurement

...? High Blood Pressure Measurement Introduction Blood pressure measurement is among the most important and commonly performed office tests; however, man people tend to undervalue the importance of the test. As a matter of fact, the according to Geddes and Newberg (1992) nearly 45% of adults tend to have high blood pressure without their knowledge. I opted to conduct this experiment in order to ascertain how blood pressure level tends to fluctuate under various body conditions. Moreover, unlike other experiments that require complex procedures and equipments that can only be conducted on animals or by...

Blood Pressure and Electrocardiography

...Human Anatomy and Physiology Calculations Define diastolic blood pressure. "Diastolic" came from the Greek diastole meaning "a drawing apart."The term has been in use since the 16th century to denote the period of relaxation of the heart muscle. The diastolic pressure is specifically the minimum arterial pressure during relaxation and dilatation of the ventricles of the heart when the ventricles fill with blood. In a blood pressure reading, the diastolic pressure is typically the second number recorded. For example, with a blood pressure of 120/80 ("120...

Blood pressure

...Blood Pressure Introduction Blood pressure is defined as the force that the blood exerts against the arterial walls (Carterand Lewsen, 2005, p. 297). Blood pressure measurement is performed during physical examination, intial assessment, and as part of routine vital signs assessment. Blood pressure measurement is one of the most essential part of nursing assessments that determines client’s health and risk for diseases. Adequate blood pressure is necessary to keep the blood flowing and to supply the body of enough oxygen and nutrients...

Blood Cholesterol/Blood Pressure

... Article Relationship between weight loss and blood pressure In a report that was issue by the world health organization, 2002. It was found that there is a growing prevalent of those with chronic diseases occasioned by obesity. In was also contained in the report that a close correlation do exist between the being obese and developing high blood pressure (Krueger, 2012). Unfortunately, there is no known cure for high blood pressure thought it can be prevented or controlled. It is therefore construable that with diminishing body weight, one significantly reduces the possibility of developing high blood pressure. The relationship of body weight and blood pressure are directly proportional. This statement should though be taken... in the...

Blood Pressure

...Insert Introduction During the laboratory activity, systolic blood pressure (the maximum pressure exerted by the blood against the artery walls) of the test subject was 110 at rest. However, this pressure increased to 120 and 140 when subject was placed under 1kg and 2.5 kg workloads respectively. This was the case as blood flow has to increase during strenuous activity (exercise) in order to supply nourishment (oxygen and nutrients) to critical organs such as the heart, brain, lungs and muscles. At the same time, diastolic pressure (the lowest pressure in the artery) at rest was measured at 70 but...

... of group 2)2 / number of observations in that group)]. In the same example SEDM= 91.86. Thus computed t is 114-111/91.86=0.03. The computed t of 0.03 is much lesser than critical t at df =5 (n1 +n2 -1) where, n1and n2 are number of observations in each group and df= degree of freedom). As it is less than critical t the area beyond the computed t in the Unit normal curve is much greater than 0.05. Hence the probability of chance is considered (Null Hypothesis accepted) and it is considered there is no significant difference between two observations (in our example systolic blood pressure). The t test was conducted as unpaired t test with unequal variance (Blair et al, 1980). Q3. Considering the anatomy of a Giraffe and Human... cardiac...
