Circulatory System

Define: deoxygenated, oxygenated, vessel, capillary artery
Blood that has already circulated throughout the body and used up its oxygen stores by supplying oxygen to the body.

After the gas exchange in the lungs, the red blood cells are now bonded with the oxygen due to their iron. This blood is pumped to the heart and then to the body.

Small tubes branching around the inside of the body that transport blood to and from the heart.

Extremely thin and small blood vessels that transfer blood from the arteries into the veins once the blood has finished its course around the body and is deoxygenated.

Blood vessels carry oxygenated blood around the body until it is used up and deoxygenated.

Blood vessels that carry deoxygenated blood from the body into the heart, then the lungs, then back into the heart to be circulated around.

Draw and Label the Structure of the Heart.

Outline the flow of blood through the heart.
Starting from deoxygenated blood – Enters the right atrium of the heart via the Vena Cava and is pumped into the right ventricle. From there, the pulmonary artery takes the Deoxygenated blood to the lungs, the gas exchange happens and the blood, now Oxygenated, comes into the left atrium via the pulmonary veins. The blood is pumped into the left ventricle and then the Aorta takes the blood and pumps it into the rest of the body. When the oxygenated blood is used up, the capillaries transfer the blood to the veins and back into the right atrium via the Vena Cava.

Compare and contrast arteries, veins, capillaries.
All three are blood vessels used in the whole cycle of blood through the body.
