Circulatory System

Exercise and the cardiovascular system

The cardiovascular system is also known as the circulatory system this system is made up of the heard and the connected tubes (vessels) called arteries, veins, and capillaries. This system contains the blood that is pumped by the heart around the whole body (over and over again).

The circulatory system may not be the only system that controls homeostasis (homeostasis is maintaining a stable state of the entire body) but it plays a vital role. The important position that the circulatory system has in controlling homeostasis depends on the steady and regulated stream of blood through the arteries; veins and capillaries that go throughout our body and enter every tissue and can reach every cell in the body.

This is basically the raw glucose the body then releases around five percent of the energy released by aerobic respiration, per molecule of glucose. The waste product is lactic acid unlike in normal reaction where the product is water. Then the Muscles become tired during the long exercise regimen This means that the muscles stop contracting smoothly and effeciently. One of the causes of this is the build-up of lactic acid in the muscles from the anaerobic respiration. The lactic acid is removed from the muscles by blood flowing through them. Fit people are able to carry out physical activities more effectively than unfit people. Their pulse rate is likely to return to normal more quickly after exercise. But being fit is not the same as being healthy. Healthy people are free from disease and infection - they may or may not be fit as well. It is possible to be fit but unhealthy, or healthy but unfit.Much less energy is released during anaerobic respiration than during aerobic respiration. This is because the breakdown of glucose is

First of all the heart rate, blood pressure and temperature were measured (all before exercise). Then the subjects then walked up and down the stairs five times each. The heart rate, blood pressure and temperature of the subjects were then recorded straight after the exercise after each two minutes until the resting rate for all three was reached. This exercise was repeated but prolonged to walking up and down the stairs then times. The third exercise was when the subjects ran around one time. When the exercise was finished, the heart rate, blood pressure and temperature were measured every two minutes until it reaches the resting rate. This exercise was prolonged when the subjects were told to run the field two times instead of one and the heart rate, blood pressure and temperature were measured again and measured every two minutes until it reaches its resting
