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
