Demonstrate the adaptability of the cardiovascular system to autoregulate to
two different, stressful conditions (1. Max test 2. Steady state exercise at 65%
maximum oxygen level). Explain in detail how the different cardiovascular
components such as heart rate, systolic blood pressure, diastolic blood pressure,
total pulmonary resistance, stroke volume and blood flow, respond to these
stressful conditions. Explain in detail the physiological mechanisms responsible
for the changes observed.
The cardiovascular system has the capabilities to adapt to a number of
external factors. An example of the cardiovascular system’s ability to adapt is
seen in response to a max test. This test measures the volume of oxygen in
the blood that the body uses in one minute of maximal exercise. A stationary
exercise machine is used when administering the test. The first minute interval is
done at a very easy level. As each minute passes the levels become increasingly
more difficult until you reach a levels when you can no longer continue. ...

Rheumatic heart disease and cardiomyopathy are potential sources of diagnostic confusion. Cardiovascular Disease (CVD) includes dysfunctional conditions of the heart, arteries, and veins that supply oxygen to vital life-sustaining areas of the body like the brain, the heart itself, and other vital organs. Hinderence in oxygen supply eventually results in death of the tissue or organ.…

His heart rate is increasing as well as his breathe per minutes. At his age, excitement is very much increased and is there for increasing also the cardiovascular activity. The cardiovascular system helps transport oxygen and nutrients to tissues, transport carbon dioxide and other metabolites to the lungs and kidneys, and distribute hormones throughout the body. The cardiovascular system also…

According to Kantrowitz and Wingert (2006), a few years back, heart diseases were considered to be the concern of men alone, and women, especially those below 50years did not have to worry about cardiovascular diseases. However, recent studies have demonstrated that both men and women, especially women after menopause and men after 55years of age are a greater risk of cardiovascular accidents…

Blood is carried back and forth through the capillaries, veins and arteries, from the heart to the lungs, known as (pulmonary circulation) and from the heart to the rest of the body (systemic circulation). World Health Organisation (WHO), the United Nations body on health has recently come out with the findings that heart disease is the number one killer disease all over the globe, followed by…
