| Question | Answer |
|---|---|
| allergy | The overreaction of the immune system to a foreign substance that is normally not a pathogen. |
| antibody | A protein the body produces to attack or mark for attack invading materials such as bacteria and viruses. |
| antigen | The molecules that the macrophages recognize as not belonging in the body, triggering the immune system. |
| aorta | The largest artery in the body; carries blood from the heart to smaller arteries. |
| artery | A blood vessel that carries blood away from the heart. |
| atria/atrium | An upper heart chamber that receives blood from the lungs or body. |
| atrioventricular valve | (AV valve) A one-way valve that separates the atrium from the ventricle in the heart and prevents a backflow of blood into the atrium. |
| autoimmune disease | A disease in which a person's immune system attacks and destroys his own cells. |
| blood clot | A collection of blood cells and fibers normally formed to prevent bleeding. |
| blood plasma | The fluid portion of the blood. |
| blood pressure | The pressure of the blood against the walls of the arteries. |
| capillary | One of many small blood vessels that have walls that are one cell thick; materials are exchanged between the blood and other body tissues in the capillaries. |
| coronary arteries | A blood vessel that supplies blood to the heart muscle. |
| deoxygenated blood | Blood that contains little oxygen. |
| erythrocytes | A red blood cell; functions primarily to transport oxygen. |
| fever | An increase of the normal body temperature. |
| heart | A muscular organ that pumps blood. |
| hemoglobin | The red pigment found in red blood cells; transports oxygen and some carbon dioxide. |
| homeostasis | The internal balance an organism must maintain. |
| immune system | The body system that gives resistance to disease. |
| immunity | The ability of an organism to recognize and attack a pathogen to which it has been previously exposed; dependent on the formation of antibodies. |
| inferior vena cava | A large vein that returns blood from the lower body regions to the heart. |
| inflammation | A local response to a foreign substance in a body; may be characterized by swelling, redness, and increased temperature. |
| kidney | An organ that filters wastes from the blood. |
| leukocyte | A white blood cell; functions primarily in the body's immune system. |
| nephron | A microscopic unit that filters blood in the kidney. |
| platelet | A small structure found in the blood; involved in the formation of blood clots. |
| pulmonary arteries | The artery that transports deoxygenated blood from the heart to the lungs. |
| pulse | The rhythmic expansion of the arteries caused by the pumping of the heart. |
| semilunar valve | A structure that allows the blood to leave the ventricles but prevents it from returning. |
| septum | A muscular wall dividing the right side of the heart from the left side. |
| superior vena cava | The large vein that carries blood from the upper body regions to the heart. |
| urea | A waste product filtered from the blood by the kidneys. |
| ureter | The tube that carries the wastes and water filtered out of the blood to the urinary bladder. |
| urethra | The tube that carries wastes away from the urinary bladder. |
| urinary bladder | An organ that temporarily stores the fluid wastes from a kidney; a reservoir for urine. |
| urine | A fluid that is passed out of the body; contains wastes from the blood. |
| vein | A blood vessel that carries blood toward the heart. |
| ventricle | A heart chamber that pushes blood into the arteries. |
| WHAT ARE THOOOOOSE | sorry about that |
