2 diseases of the system and how they affect system?
CAD occurs when the arteries that supply blood to the heart become narrowed or blocked by plaque, a build-up of fat, cholesterol, and other substances. This can cause chest pain (angina), shortness of breath, and fatigue. In some cases, CAD can lead to a heart attack, which occurs when the blood supply to the heart is completely blocked.
How CAD affects the cardiovascular system:
* CAD decreases the amount of oxygen-rich blood that reaches the heart muscle. This can lead to angina, chest pain that occurs when the heart muscle is not getting enough oxygen.
* CAD can also lead to a heart attack, which occurs when the blood supply to the heart is completely blocked. A heart attack can cause serious damage to the heart muscle and can even be fatal.
* CAD can also lead to heart failure, a condition in which the heart is unable to pump enough blood to meet the body's needs.
2. Stroke
A stroke occurs when the blood supply to the brain is interrupted or reduced. This can be caused by a blockage in an artery in the brain (ischemic stroke), a rupture of an artery in the brain (hemorrhagic stroke), or a temporary interruption of blood flow to the brain (transient ischemic attack, or TIA).
How stroke affects the cardiovascular system:
* Stroke can damage the blood vessels in the brain, which can lead to further strokes.
* Stroke can also lead to heart disease, as it can increase the risk of developing conditions such as high blood pressure, high cholesterol, and diabetes.
* Stroke can also lead to heart failure, as it can damage the heart muscle and make it unable to pump blood effectively.
