| The total amount of air that a person can exhale after taking as deep a breath as possible | Vital Capacity |
| The amount of air that remains in the lungs after a person exhales as forcefully as he or she can. | Residual volume |
| The movement of air into and out of the lungs | Ventilation |
| The mechanical process of moving air into and out of the lungs | Breathing |
| Tiny hair-like extensions of cells that line the respiratory tract. Move in wave like fashion to help eliminate dust and germs from the body | Cilia |
| Tiny sacs in the lungs through which the exchange of oxygen and carbon dioxide takes place. | alveoli |
| The tube that carries air to lungs and is also known as windpipe | trachea |
| The process by which substances combine with oxygen | oxidation |
| A rapid form of oxidation that releases heat and in many cases, light. | combustion |
| The process that occurs in the mitochondria of the call by which glucose combines with oxygen to produce carbon dioxide, water and energy. | cellular respiration |
| A unit of measure for heat energy. | calorie |
| The scientist who first discovered a vaccine for polio | Jonas Salk |
| The scientist who discovered that our blood circulates in a closed system | William Harvey |
| This structure blocks the opening to the trachea during swallowing | epiglottis |
| A transport system in which the fluid is confined within vessels | Closed Circulatory System |
| One of the two thin-walled upper chambers of the heart | Atrium |
| The largest artery in the human body that takes blood away from the heart | Aorta |
| The largest of blood vessel that take blood away from the the heart | Artery |
| One of the think-walled lower chambers of the heart;the pumping part of the heart | Ventricle |
| One way vessels that transport deoxyenated blood, and other waste back to the heart | Vein |
| The number of times the heart beats in a given unite of time | heart rate |
| The smallest,thinest-walled vessels that carbon dioxide and oxygen pass thorugh | Capillaries |
| A structure in the heart and some veins that prevents the blood from flowing backward | Valve |
| The solid substances that aids in the clotting of blood | platelets |
| The liquid part of the blood | Plasma |
| A group of antigens on red blood cells named after the Rhesus monkey in which it was first found; blood that has this group of antigens is cal Rh-positive;blood that does not have these antigens is called Rh-negative | Rh factor |
| The number of times the heart beatsin a given unit of time (usually one minute) | Heart rate |
| The rhythmic expansion and recoil of arteries; initiated by the contractions of ventricles of the heart | Pulse |
| The force exerted by blood against vessel walls | Blood pressure |
| A lipid found in animal fat and most animal tissue. That may cause thickening of the artery walls | Cholesterol |
