Exercise for a minute did not significantly change heart rate as compare to working in the office as hypothesised. This indicated that working in the office also needed extra energy comparable with short exercise. Heart rate after eating and digesting food was similar to exercise for one minute. This is why cardiologists advise heart patients to avoid exercise or walk for at least two hours after taking meals.
Drinking coffee increases heart rate but the recent research indicated that it is beneficial for heart diseases in moderate quantity in elderly people ( James et el, 2007). Coffee has oxidative properties which keep the LDL cholesterol level under low levels and chances of getting cardiovascular disease are minimal.
Heart beats per minute were expected to be equal to or lower than resting time but in my case it was higher. The probable cause for this change may be dreams immediately before wake up which resulted in elevated heart rate.
3. Trained athletes have resting pulse rate at 40-60 as their metabolism has adjusted to exercise. Therefore exercise is recommended for proper body functioning and keeping healthy heart. My resting pulse rate is also low because I exercise regularly. It means my heart need to work less as compare to persons whose heart rate at resting is 70-72 beats per minute.
4. I calculated my BMI using standard BMI calculator given by National Institute of Health. My height is 5’ 5” and weight 152 pounds. The BMI come to 25.3 which are on the higher side of the normal range (18.5 – 24.9) of NIH standards. My BMI does surprise me because I have kept my body weight within limit. I take care of my food and exercise regularly. Therefore, my heart rate is lower and it is expected that I have low risk of mortality due to heart problems.
5. People who have criticized BMI have ...Download file to see next pagesRead More

...The maintenance of a constant internal environment of an organism is called homeostasis, a process of utmost importance for the body, failure at which would lead to disastrous, if not fatal, consequences (Taylor, Green, & Stout, 1984). The basis of homeostasis lies in the concept of negative feedback i.e. if the system is disturbed; the disturbances set in motion a sequence of events which tends to restore the system to its original state. Following are three of hundreds of examples that can be explained through the concepts of homeostasis. I. Regulation of blood glucose level: One of the most important metabolites in the human body is glucose and, therefore, its concentration in the body has to be...

Immediately after eating, he experienced moderate chest discomfort that radiated to his left shoulder and descended into the left arm and the little finger. The pain was unrelieved by nitroglycerin tablets, so he was admitted to the hospital for further evaluation. A cardiac catheterization revealed a partial blockage of four coronary arteries, and he was scheduled for bypass surgery. Discuss the consequences of decreased coronary blood flow on myocardial function; a description of cardiac catheterization, and a description of the bypass procedure (CABG, coronary artery bypass graft). The Consequences of Decreased Coronary...

However, this has been effectively accounted based on the Darwin’s evolution theory. According Darwin (1859), the environment plays a crucial role in shaping the behavior and appearance of organisms. As organisms interact with the environment, they become adapted, depending on their demands. The man who went to the North interacted with a set of different environmental conditions that made him to become light-skinned. Response to Question 2 Based... on the...
