Transport
| Term | Definition |
|---|---|
| Alveoli | tiny air sacs of the lungs which allow for a rapid gaseous exchange |
| Nephron (s) | each of the functional units in the kidney, consisting of a glomerulus and its associated tubule, through which the glomerular filtrate passes before emerging as urine. |
| Deoxygenated | to not have oxygen |
| Oxygenated | to have oxygen |
| Valve(s) | device that opens or closes to let things through or to prevent passage |
| Septum | a partition separating two chambers |
| Artery | muscular-walled tubes forming part of the circulation system by which blood (mainly that which has been oxygenated) is conveyed from the heart to all parts of the body. |
| Vein(s) | tubes forming part of the blood circulation system of the body, carrying in most cases oxygen-depleted blood toward the heart. |
| Capillary | fine branching blood vessels that form a network between the arterioles and venules |
| Ventricle(s) | each of the two main chambers of the heart, left and right |
| Atrium (atria) | each of the two upper cavities of the heart from which blood is passed to the ventricles. The right atrium receives deoxygenated blood from the veins of the body; the left atrium receives oxygenated blood from the pulmonary vein |
| Pulse | a rhythmical throbbing of the arteries as blood is propelled through them, typically as felt in the wrists or neck |
| Lymphocyte(s) | a form of small leukocyte (white blood cell) with a single round nucleus, occurring especially in the lymphatic system |
| Antibody | a blood protein produced in response to and counteracting a specific antigen. Antibodies combine chemically with substances which the body recognizes as alien, such as bacteria, viruses, and foreign substances in the blood |
| Plasma | the colorless fluid part of blood, lymph, or milk, in which corpuscles or fat globules are suspended |
| Immunity (passive/active) | Active immunity involves your bodies direct response to an unknown pathogen. Passive immunity is an immune response which involves antibodies obtained from outside the body. |
| Platelets | a small colorless disk-shaped cell fragment without a nucleus, found in large numbers in blood and involved in clotting |
| Antigen | a toxin or other foreign substance which induces an immune response in the body, especially the production of antibodies |
| Agglutination | the clumping of particles. Agglutination is the process that occurs if an antigen is mixed with its corresponding antibody called isoagglutinin. |
| Pathogen | a bacterium, virus, or other microorganisms that can cause disease |
| Vena cava | a large vein carrying deoxygenated blood into the heart. There are two in humans, the inferior vena cava (carrying blood from the lower body) and the superior vena cava (carrying blood from the head, arms, and upper body). |
| Aorta | the main artery of the body, supplying oxygenated blood to the circulatory system. In humans it passes over the heart from the left ventricle and runs down in front of the backbone |
