• The blood vessels that carry oxygenated blood away from the heart are the arteries.

What is the purpose of capillaries in the circulatory system?

• Capillaries store excess nutrients in the body

• Capillaries regulate body temperature

• Capillaries transport blood from the heart to the lungs

• Capillaries are responsible for the exchange of oxygen, nutrients, and waste products between the blood and the body's tissues.

What is the main function of veins in the circulatory system?

• Las venas transportan la sangre al resto del cuerpo.

• Las venas ayudan a regular la presión arterial.

• Las venas transportan oxígeno a los pulmones.

What is the role of red blood cells in the transport of oxygen and nutrients?

• Red blood cells transport carbon dioxide from the body's tissues to the lungs and carry waste products away from cells.

• Red blood cells transport oxygen from the lungs to the body's tissues and carry nutrients to cells.

• Red blood cells are responsible for producing insulin and regulating blood sugar levels.

• Red blood cells help in the digestion of food and absorption of nutrients in the small intestine.

What is the process called when oxygen and nutrients are exchanged between the blood and body tissues?
