blood flow
Blood flow refers to the movement of blood through the circulatory system, which includes the heart, arteries, veins, and capillaries. The heart pumps oxygen-rich blood from the lungs into the arteries, which carry it to the body's organs and tissues. After delivering oxygen and nutrients, the blood collects carbon dioxide and waste products and returns to the heart through veins. From there, it is pumped to the lungs to release carbon dioxide and receive fresh oxygen. This continuous cycle is vital for maintaining health, delivering essential substances, and removing waste from the body.

Blood flow refers to the movement of blood throughout the body, powered by the heart. Oxygen-rich blood is pumped from the heart into the arteries, which carry it to various organs and tissues. Cells use the oxygen and nutrients in the blood, creating carbon dioxide and waste. This deoxygenated blood returns through veins to the heart, where it is sent to the lungs to release carbon dioxide and pick up new oxygen. This continuous cycle is vital for sustaining life, ensuring that every cell receives necessary nutrients while removing waste products.
