What type of circulation is responsible for the transport nutrient to body tissues why?

The type of circulation responsible for the transport of nutrients to body tissues is systemic circulation. Here's why:

Systemic circulation: Systemic circulation refers to the portion of the circulatory system that pumps oxygenated blood from the heart to the rest of the body and returns deoxygenated blood back to the heart. It involves the systemic arteries, capillaries, and systemic veins.

Nutrient transport: The main function of systemic circulation is to deliver oxygen, nutrients, hormones, and other essential substances to the body's tissues and cells. Oxygen and nutrients are taken up by the blood in the capillaries of the lungs, where the pulmonary circulation occurs. The oxygenated blood is then pumped by the heart through the systemic arteries to all parts of the body.

Arteries: Systemic arteries carry oxygenated blood away from the heart to the tissues. As the arteries branch out into smaller vessels, they eventually reach the capillary beds within the tissues.

Capillaries: Capillaries are the smallest and most numerous blood vessels in the body. They form networks that allow for the exchange of substances between the blood and the surrounding tissues. Oxygen, nutrients, and waste products are exchanged through the thin walls of the capillaries.

Veins: Deoxygenated blood, along with waste products like carbon dioxide, is collected from the tissues by capillaries. These capillaries merge into larger vessels called venules, which eventually form systemic veins. The systemic veins carry the deoxygenated blood back to the heart, completing the systemic circulation.

In summary, systemic circulation is responsible for the transport of nutrients to body tissues by delivering oxygenated blood to the capillaries, where nutrients are exchanged with the surrounding cells. The systemic arteries, capillaries, and systemic veins work together to facilitate this vital nutrient transport process.
