| Arteries | Thick-walled blood vessel that carries blood away from the heart |
| Veins | Thin-walled blood vessel that carries oxygen-poor blood to the heart. They are contain valves. |
| Arterioles | The smallest blood vessel that comes from an artery. |
| Capillaries | Very thin-walled (one cell thick) where gas, nutrients and wastes are exchanged with the cells. Connect arterioles and veins. |
| Heart | Composed of cardiac muscle and has four chambers. |
| Superior Vena Cava | Blood vessel which brings oxygen-poor blood from the upper parts of the body into the right atrium |
| Inferior Vena Cava | Blood vessel which brings oxygen-poor blood from the lower parts of the body into the right atrium |
| Right Atrium | Receives blood from the inferior and superior vena cava and pumps it into the right ventricle |
| Right Ventricle | Receives blood from the right atrium and pumps it into the pulmonary artery |
| Pulmonary Artery | Receives blood from the right ventricle and transports it into the lungs |
| Pulmonary Vein | Receives oxygen-rich blood from the lungs and transports it to the left atrium |
| Left Atrium | Receives blood from the pulmonary veins and pumps it into the left ventricle |
| Left Ventricle | Receives blood from the left atrium and pumps it into the aorta |
| Aorta | Receives blood from the left ventricle and transports it to the rest of the body |
| Septum | Separates the heart into a left side and a right side |
| Pulmonary Circulation | The pathway from which blood flows from the heart to the lungs and back to the heart |
| Systemic Circulation | The pathway that carries blood from the heart to all parts of the body with the exception of the lungs |
| Coronary arteries | Supplies oxygen-rich blood to the heart muscle |
| Tricuspid valve | Valve between the right antrium and the right ventricle |
| Pulmonary valve | Valve between the right ventricle and the pulmonary artery |
| Mitril valve | Valve between the left atrium and the left ventricle. |
| Aortic valve | Valve between the left ventricle and the aorta. |
| What helps blood to clot? | Platelets |
| Which blood cell helps to destroy germs? | White blood cells |
| What give blood its red color? | Hemoglobin |
| Which chamber of the heart pumps blood to the body? | Left ventricle |
| What kind of muscle makes up the heart? | Cardiac |
| How many valves in the heart? | Four |
| What are the main parts of the circulatory system? | heart, blood, and blood vessels |
| What are the main parts of blood? | red blood cells, plasma, white blood cells and platelets |
