circulatory system

The human circulatory system is a complex network essential for maintaining homeostasis and overall health. Comprising the heart, blood vessels, and blood, it ensures the transportation of oxygen, nutrients, and waste products throughout the body.

which can lead to blockages in blood vessels

Abnormal clotting of blood

leading to cell damage and potential loss of function

A disruption of blood supply to the brain

narrowing them and restricting blood flow

The buildup of plaque in the arteries

and other complications

stroke

High blood pressure that can lead to heart disease

and carbon dioxide is released into the lungs to be exhaled

oxygen from the inhaled air diffuses into the bloodstream

At the lungs' alveoli

Oxygenated blood returns to the heart through the pulmonary veins

and the blood becomes oxygenated

carbon dioxide is exchanged for oxygen

In the lungs

Deoxygenated blood is pumped from the heart's right ventricle to the lungs through the pulmonary artery

and the blood becomes oxygenated before returning to the heart

oxygen is exchanged for carbon dioxide

At the capillaries

Deoxygenated blood returns to the heart through the veins

and eventually reaches the body's tissues

which branches into smaller arteries

Oxygenated blood is pumped from the heart's left ventricle through the aorta

The circulatory system carries white blood cells and antibodies to fight against pathogens and infections

The circulatory system helps regulate body temperature by transporting heat from the core to the skin's surface

where it can be released

Metabolic waste

Carbon dioxide

from the cells to the lungs for exhalation

a waste product of cellular respiration

The circulatory system carries carbon dioxide

Nutrients

Oxygen

thin-walled vessels that allow for the exchange of gases and nutrients between the blood and surrounding tissues

Tiny

preventing backflow

Valves in the heart ensure that blood flows in the correct direction
