What is the main function of veins?

To carry deoxygenated blood back to the heart.

Front

What is the structure of capillaries?

Back

Capillaries are thin-walled blood vessels that allow for the exchange of materials between blood and tissues.

Front

What is hydrostatic pressure?

Back

The pressure exerted by a fluid at rest due to the force of gravity.

Front

What is osmotic pressure?

Back

The pressure required to prevent the flow of water across a semipermeable membrane, often due to solute concentration.

Front

What are arterioles?

Back

Small blood vessels that branch from arteries and lead to capillaries, regulating blood flow.

Front

What are elastic arteries?

Back

Large arteries that can stretch and recoil to accommodate the surge of blood from the heart.

Front

What are muscular arteries?

Back

Medium-sized arteries that have more smooth muscle and are responsible for distributing blood to various parts of the body.

Front

What is the role of capillaries in the circulatory system?

Back

Capillaries facilitate the exchange of oxygen, carbon dioxide, nutrients, and waste products between blood and tissues.

Front

What is an arteriovenous anastomosis?

Back

A direct connection between an artery and a vein, allowing blood to bypass capillaries.
