Answer:

Blood is transported in arteries, veins and capillaries.

Blood is pumped from the heart in the arteries. It is returned to the heart in the veins.

The capillaries connect the two types of blood vessel and molecules are exchanged between the blood and the cells across their walls.

Always carry blood away from the heart Always carry blood to the heart

Carry oxygenated blood, except for the pulmonary artery Always carry deoxygenated blood, except for the pulmonary vein
