Transport - by LONG
Transport & Circulatory System
| Word/Term | Definition/Description |
|---|---|
| aerobic | Using oxygen. |
| absorption | Process when materials cross cell membranes from the outside environment into the body. |
| circulation | Process when materials are circulated throughout the body to where they are needed. |
| transport | A life function that includes the movement of materials, nutrients, oxygen, and wastes. Includes absorption and circulation. |
| fluid | A liquid; blood is a fluid tissue; all cells are coated with fluid |
| blood vessels | Tubes that carry and deliver materials around the body |
| blood pressure | The amount of force the elastic arterial walls exert on the blood inside |
| heart | The pump of the circulatory system |
| chamber | Hollow compartments in the heart muscle that receive and pump blood There are 4 in the human heart. |
| efficient | Achieving maximum productivity |
| lungs | Organs that bring in oxygen and remove carbon dioxide from the body. |
| blood | A liquid tissue that is made up of cells, cell parts, and liquid. |
| left atrium | Top left chamber of the heart that receives oxygen rich blood from the lungs. |
| left ventricle | Top bottom chamber of the heart that receives oxygen rich blood from the left atrium and pushes the blood into the aorta towards the body. |
| oxygen-rich | Containing a lot of oxygen in the blood. |
| aorta | The largest artery in the blood that carries oxygen-rich blood from the left ventricle to the smaller arteries toward the body. |
| artery | A thick, muscular blood vessel that carries oxygen-rich blood AWAY from the heart toward the body. High blood pressure. |
| Ms. Long | Your science teacher. |
| elastic | Being able to stretch and be flexible. |
| expand | Muscles become wider and relaxed. |
| contract | Muscles become shorter and tighter. |
| pulse | The blood pressure against the arterial walls. One of these for every heartbeat. |
| heartbeat | The contraction and relaxation of the heart muscle. |
| capillaries | The thinnest blood vessels in which only one red blood cell travel at a time. Diffusion and gas exchange occurs here. |
| body cells | The site in which oxygen diffuses out of the blood to be used for respiration and carbon dioxide diffuses into the blood. |
| veins | Flat, thin muscular vessels, that contain valves and carry blood to the heart from the body cells. Low blood pressure. |
| valves | Structures found in veins and in the heart to prevent back flow of blood. |
| deoxygenated | Blood low in oxygen. |
| right atrium | Top right chamber of the heart that receives deoxygenated blood from the body cells. |
| right ventricle | Bottom right chamber of the heart that receives deoxygenated blood from the right atrium and pushes the blood into the pulmonary arteries toward the lungs. |
| red blood cells | Doughnut shaped cells found in the blood that carry oxygen. |
| white blood cells | Cells in the blood that protect us from disease. |
| platelets | Cell fragments that begin the clotting process. |
| plasma | Yellow colored liquid portion of the blood that is 90 percent water but also contains many important proteins, salts, vitamins, hormones, gases, sugars, and other nutrients. |
| diffusion | A movement of molecules from an area of higher concentration to an area of lower concentration. Gas exchange occurs by diffusion. |
| ICF | Intercellular fluid, the fluid that surrounds all cells |
| tissue | groups of similar cells that work together to perform the same function |
| organ | groups of similar tissues that work together to perform the same function |
| organ system | groups of similar organs that work together to perform the same function |
| clotting | a chemical process that results in the production of a clot which stops the flow of blood out of a damaged vessel. |
| fibrinogen | a protein found in the plasma that helps with clotting process. |
| hemoglobin | a protein found in the red blood cells that carries the oxygen molecule. |
| cardiovascular | heart vessels |
| vena cava | the largest vein that carries deoxygenated blood into the right atrium. |
| pulmonary veins | Blood vessels that carry oxygen-rich blood to the heart from the lungs. |
| pulmonary arteries | Blood vessels that carry deoxygenated blood away from the heart to the lungs. |
| heart attack | A potentially fatal condition when the coronary arteries get blocked and the heart tissue beyond that point is not supplied with blood and the muscle tissue in that area of the heart dies. |
| coronary arteries | Blood vessels that supply blood to the heart muscle. |
| cardiac muscle | An involuntary muscle that makes up the heart. |
| cholesterol | Animal fat that can deposit inside the walls of arteries and cause hardening and blockages. |
| stroke | A potentially fatal condition when the arteries in the brain are blocked and deprive brain tissue from blood and oxygen. |
| hemophilia | a rare, inherited bleeding disorder in which your blood doesn’t clot normally. If you have hemophilia, you may bleed for a longer time than others after an injury. You also may bleed internally this bleeding can damage the organs/tissues and can be fatal. |
| atherosclerosis | Disease in which the arteries harden and lose their elasticity. This can be caused by smoking and too much fat in the diet. This usually causes high blood pressure. |
| septum | The thick muscular wall in the heart that separates the left oxygen-rich side from the right deoxygenated side. |
| spygmanometer | A device that measures blood pressure. |
| hypertension | Also called high blood pressure, it can be causes by too much cholesterol and fat in the diet, smoking, and sometimes genetics. |
