Cardiovascular

Cardiovascular is a circulatory system comprised the heart and blood vessels which carries nutrients and oxygen to the tissues of the body and removes carbon dioxide and other wastes from them. Cardiovascular disease is the class of diseases that involve the heart or blood vessels (arteries and veins).

There is therefore increased emphasis on preventing atherosclerosis by modifying risk factors, such as healthy eating, exercise and avoidance of smoking.

Cardiovascular diseases affect the heart and blood vessels and include:
• Arteriosclerosis
• Coronary artery disease
• Heart valve disease
• Arrhythmia

• Heart failure
• Hypertension
• Orthostatic hypotension
• Shock
• Endocarditic
• Diseases of the aorta and its branches
• Disorders of the peripheral vascular system, and
• Congenital heart disease.

The cardiovascular system serves five important functions during exercise:

• Delivers oxygen to working muscle
• Oxygenates blood by returning it to the lungs
• Transports heat from the core to the skin
• Delivers nutrients and fuel to active tissues
• Transports hormones.

Regular exercise helps the cardiovascular system:
Blood Pressure: Regular exercise forces the heart to get into shape, allowing it to increase the efficiency with which it pumps blood around your body.

Cholesterol: Regular exercise causes the rate of blood flow throughout the body to increase, which helps “flush out” the bloodstream, removing troublesome products before they develop into a potential threat.

Improved Recovery: Regular exercise improves the heart ability to recover from stressful situations.

Capillary Density Increases: Due to the increased blood flow to the muscles, the muscles develop additional capillaries to better utilize the additional blood and nutrients contained therein.

Disease Prevention: Keeping your cardiovascular system in shape through exercise is the best way to lower your probability of suffering cardiac conditions, such as a heart attack or stroke.
