Question 2

what effect does hyperinflated lungs (caused by asthma) have on the circulatory system, if at all? what possible symptoms may manifest as a result of this condition?

Accepted Answer

These findings are usually transient &amp; improve as the asthma event comes into control. Mild stress on the right side of the heart is usually well tolerated with no outward symptoms.

Question 3

how can  poor diet affect the function of the circulatory system?

Accepted Answer

Atherosclerosis: This condition is caused by poor diet which is typically a diet with too much animal fat in it. It also occurs in obese people and in those who have diabetes once again due to over eating. Excessive fat(cholesterol) is deposited inside the arteries which leads to damaged vasculature , a set up for heart attack and or stroke due to blood clots forming inside the diseased arteries.

Question 4

how does the respiratory system depend on the circulatory system?

Accepted Answer

Inter-dependent: relationship exists between the two. The heart pumps arterial  blood to the circulation. The deoxygenated or venous blood returns to the lung where blood is oxygenated. Then blood flows into the heart chambers and the cycle continues on.

By limiting or reducing the exercise, the bodies tissues will be hard pressed to maintain, let alone grow and develop to the degree necessary to survive in a healthy state.

why does the body need a circulatory system?

Accepted Answer

Easy.: Circulatory system is essential to move nutrients and oxygen to cells and to remove waste. Having a transport system allows cells to specialize. If there were no circulation every cell would have to perform many more functions independently.

atherosclerosis(hardening of the arteries). This can lead to heart attack(coronary artery occlusion), stroke or peripheral vascular disease(may cause gangrene from poor circulation in the legs).
