Michael was studying the human circulatory system and came across the term 'Vena cavae'. He learned that they: _______

• are the large veins carrying deoxygenated blood into the heart from the brain and body

• are the arteries carrying oxygenated blood from the heart

• are the capillaries involved in gas exchange

• are the vessels supplying blood to the liver
