Regular exercise is a protective factor against cardiovascular diseases.

The aorta transports oxygenated blood from the heart to the body.

Fibrillation is the irregular and rapid beating of the heart.

The endothelium helps regulate blood pressure in blood vessels.

Aldosterone increases water retention in the kidneys, affecting blood pressure.

The lymphatic system is not primarily responsible for transporting nutrients.

Ischemia occurs when blood flow is restricted due to narrowed or blocked vessels.
