If the heart malfunctions, all other body systems will be starved of oxygen.
The cardiovascular system provides the body with vital nutrients and oxygen through a complex network, whereby all organs, body systems, and body tissues receive oxygen-rich blood.
- Heart is a muscular-type organ that animals and humans possess, which performs the function of pumping blood to the rest of the body.
- Oxygenated blood flows from the heart through the arteries, which branch into the smaller arterioles until finally dividing into the capillaries.
- The capillaries pass into the venules, which open into the veins, which become larger in cross section until the blood finally flows back to the heart.
- In the capillary area, the transfer of oxygen and nutrients from the blood to the tissues can take place and also allows waste products to pass from the tissues into the blood.
Therefore, we can conclude that if the heart malfunctions, all other body systems will be starved of oxygen.
