| Arteries | blood vessels that carries blood AWAY from the heart |
| Capillaries | TINY blood vessels that connect arterioles and venules and allows for exchange of nutrients and gasses between the blood and the body cells |
| Circulatory System | AKA the cardiovascular system. Consists of the heart, blood vessels, and blood. It transports oxygen and nutrients to the body cells and transports CO2 away from body cells |
| Diastole | relaxation of the heart |
| Endocardium | membrane lining of the inside of the heart |
| Left Atrium | receives oxygenated blood from the lungs (upper left of the heart) |
| Left Ventricle | receives blood from the left atrium and pumps the blood into the aorta for transport to the body cells. |
| Mitral Valve | located between the left atrium and left ventricle. |
| Myocardium | thickest and muscular layer of the heart |
| Pericardium | sac that covers the outside of the heart |
| Pulmonary valve | between the right ventricle and the pulmonary artery. |
| Right Atrium | receives oxygenated blood from the body, located in the upper right of the heart |
| Right Ventricle | receives blood from the right atrium and pumps the blood into the pulmonary artery which feeds into the lungs where the blood can be oxygenated; it is located in the lower right portion of the heart |
| Septum | muscular wall that separates the heart into right and left; it prevents blood from moving between the right and left sides |
| Systole | when the ventricles contract |
| Tricuspid Valve | located between the right atrium and right ventricle |
| Veins | vessels that carry blood back to the heart |
