1. Muscle that pumps blood through body Carries Oxygen rich blood from the left ventricle to the body Carries Oxygen poor blood from the right ventricle to lungs Trachea divides into 2 branches which enters the lungs Where gas exchange occurs (oxygen in, carbon dioxide out) Tiny hollow air sacs that make up the lungs. Chambers of the heart that receive blood from the artia and pump blood out to either the body (left) or the lungs (right)

2. Artery that carries nutrients and oxygen to the heart muscle cells. Chambers of the heart that receive blood from either the body (right) or the lungs (left) and pump blood to the ventricles. “Flaps” on the atria to increase the volume of the chamber Large vein that carries blood from the upper body to the right atrium Large vein that carries blood from the lower body to the right atrium Any blood vessel that carries blood Away Any blood vessel that carries blood to the heart

4. From behind Right Ventricle Right Atrium Superior vena cava Pulmonary Arteries Pulmonary Veins

5. From the Front Rigth Ventricle Left Ventricle Left Atrium Pulmonary Arteries Superior Vena Cava Right Atrium Coronary artery

6. Filters water and other waste from the blood and excretes them Tube that carries fluid from the kidney to your bladder Stores Urine Tube through which urine is released Produces adrenaline and other hormones

7. Produces sperm and hormones (testosterone) Produce eggs and hormones (estrogen and progesterone) Where fertilized egg develops Where sperm is stored Tube through which sperm is released
