- Blood Flow: The heart pumps oxygenated blood throughout the body, while the blood vessels (arteries, veins, and capillaries) facilitate the exchange of oxygen and nutrients with body tissues.
- Oxygenation: Oxygen-depleted blood returns to the heart, where it's re-oxygenated and pumped back out to the body.
- Blood Pressure: The force exerted by blood on the blood vessels is known as blood pressure, which is regulated by the heart and blood vessels to ensure optimal blood flow.
- Individuals with pre-existing cardiovascular conditions
Arteries carry oxygenated blood away from the heart, while veins return oxygen-depleted blood to the heart. Capillaries, tiny vessels, facilitate the exchange of oxygen and nutrients with body tissues.
The heart serves as the central organ of the circulatory system, pumping blood throughout the body and maintaining blood pressure.
