3.4 ✨ heart blood flow mastery

The function of the heart in the cardiovascular system is to:

• pump blood throughout the body

• filter waste from the blood

• produce hormones

• store nutrients

The role of blood vessels in the cardiovascular system is to:

• transport blood throughout the body

• produce blood cells

• store nutrients

• regulate body temperature

An 'artery' in the context of the cardiovascular system is defined as:

• A blood vessel that carries blood away from the heart

• A blood vessel that carries blood towards the heart

• A chamber of the heart

• A type of blood cell

A 'vein' in the context of the cardiovascular system is defined as:

• a blood vessel that carries blood away from the heart

• a blood vessel that carries blood towards the heart

• a blood vessel that exchanges nutrients and waste with tissues

• a blood vessel that is only found in the lungs

The function of capillaries in the cardiovascular system is to:

• transport oxygen and nutrients to tissues and remove waste products

• pump blood throughout the body

• regulate blood pressure

• store blood

The primary function of blood in the cardiovascular system is to:

• transport nutrients and oxygen to cells

• regulate body temperature

• protect against pathogens

• maintain blood pressure

The term 'circulation' in the cardiovascular system refers to:

• the movement of blood throughout the body

• the process of breathing

• the digestion of food

• the transmission of nerve signals

The role of the aorta in the cardiovascular system is to:

• pump blood to the lungs

• carry oxygenated blood from the heart to the rest of the body

• filter blood in the kidneys

• store blood for emergencies

The function of the pulmonary artery in the cardiovascular system is to:

• carry oxygenated blood from the heart to the lungs

• carry deoxygenated blood from the heart to the lungs

• carry oxygenated blood from the lungs to the heart

• carry deoxygenated blood from the lungs to the heart

The role of the vena cava in the cardiovascular system is to:

• transport oxygenated blood from the heart to the body

• transport deoxygenated blood from the body to the heart

• pump blood to the lungs for oxygenation

• regulate blood pressure in the arteries
