Which type of blood vessel carries deoxygenated blood back to the heart?

Venules

Veins (correct)

Arteries

Capillaries

What is the primary function of red blood cells (erythrocytes) in the circulatory system?

Facilitating the immune response through white blood cells

Transporting oxygen to cells (correct)

Carrying waste products away from cells

Regulating body temperature and pH balance

What are the functions of the heart in the circulatory system?

The heart acts as a pump to propel blood throughout the body, pushing oxygen-rich blood into the arteries and receiving oxygen-poor blood to be pumped to the lungs for oxygenation.

Describe the functions of arteries in the circulatory system.

Arteries carry oxygenated blood away from the heart to various parts of the body and have thick, muscular walls to withstand high pressure. Signup and view all the answers

Explain the primary functions of veins in the circulatory system.

Veins carry deoxygenated blood from the body back to the heart and often have one-way valves to prevent blood from flowing backward. Signup and view all the answers

What is the function of capillaries in the circulatory system?

Capillaries enable the exchange of oxygen, nutrients, and waste products between the bloodstream and the body's cells, vital for nourishment and waste removal. Signup and view all the answers

List and describe the functions of the components of blood in the circulatory system.

Blood transports oxygen and nutrients, carries waste products away from cells, facilitates the immune response, regulates body temperature and pH balance, and transports hormones and signaling molecules. It consists of red blood cells, white blood cells, platelets, and plasma, each playing specific roles. Signup and view all the answers

What are the primary functions of the circulatory system?

How does the circulatory system support cellular respiration?

The circulatory system delivers oxygen-rich blood from the lungs to the body's cells, providing the necessary oxygen for cellular respiration, which is the process by which cells generate energy. Signup and view all the answers

What role does the circulatory system play in nutrient distribution?
