The general function of the cardiovascular system is to transport blood throughout the body to allow the exchange of substances (e. g., respiratory gases, nutrients, and waste products) between the blood of capillaries and the body's cells.

The "goal" of the cardiovascular system is to provide adequate perfusion to all body tissues.

Explanation:

The cardiovascular system is vital for life. During the day and during the night, minute by minute, our cells need nutrients and oxygen.

Thanks to a complex and complete system of “pipes”, the heart, as if it were a double pump, is able to propel, through the arteries, the oxygenated blood and the nutrients necessary to give life to all the cells of the body, and in less than a minute.

The blood vessel network, in the form of eight, performs the following functions:

the rapid transport of blood with oxygen and nutrients to human body tissues and organs, as well as the collection of metabolic wastes. It also carries vital substances for body homeostasis.

Hormonal control: it takes hormones to the target organs and secretes its own hormones.

Temperature regulation: controls the distribution of heat between the center of the body and the skin.

Reproduction: helps an erection to occur.

the defense against pathogens: it carries immune cells and antibodies.

the expulsion of substances and salts through the filtrate of the kidney maintaining the pH of the blood and the balance of sodium (salt) and potassium, essential for life.
