Human Biology Exam
| Term | Definition |
|---|---|
| Passive Immunity | A form of immunity that is gained through an annoculation of already made antibodies and antitoxins. The annoculation would fight off the pathogens. |
| Vaccination | The injection of either Antibodies or weakened form of live pathogens to gain immunity. |
| Immunisation | Making yourself immune |
| Active Immunity | A form of immunity that is gained by a person getting the virus can be through a vaccination of a weakened form of the virus and gains immunity by the human body making its own antibodies in response to the pathogen. |
| Artificial Immunity | Immunity from an artificial form of the live pathogen |
| Maternal Immunity | Immunity passed on from mother (through the placenta) then after birth through breast milk until few months after the baby starts making antibodies of its own. |
| Monocytes | A large, circulating, phagocytic white blood cell, having a single well-defined nucleus. |
| Lymphocytes | Specialized white blood cells. Single round nucleus found in the lymphatic system. |
| Phagocytes | Cells that are capable of engulfing and absorbing pathogens and other particles. |
| Antibodies | A blood protein made in response to pathogens. |
| Antigens | The target of the immune system. Carries pathogens. |
| First line of defense in body | Skin, cilia, mucus, hair, saliva, sweat, blood clot. |
| Seconds line of defense in body | When the pathogen do get pass the first line of defense and causing the white blood cells to work. |
| Boosters | To get a re-vaccination. |
| Re-vaccination | A repeat of the injection you already had before to keep the antibodies working. |
| Pathogens | A disease causing organism. |
| Symptoms | A physical sign that the pathogen has gone into your body. |
| Inflammation Response | Inflammation response is pain, swelling, itching, redness and heat. |
| Histamine | Released by cells in response to cut, injury to conduct the inflammation response. |
| Memory Cell | A already encountered a specific antigen and after that produces large amounts of antibodies to fight off it. |
| Basil membrane cell | the fraction of the plasma membrane at the Basal side of the cell, which faces the underlying tissue. |
| Support cell | Any cell that function is to support the epithelial membrane or tissue. |
| Olfactory cell | Senses smell by doing something chemically to molecules. |
| Goblet cell | Secretes mucus can be found in the stomach lining, small intestines, respiratory passageway. |
| Ciliated cell | Any cells that has cilia/hair. |
| Fibroblast | A cell which produces collagen and other fibres. allows air sacs to be strong and not break |
| Macrophage | Phagocytic cell found in the tissues or as a mobile white blood cell, especially at sites of infection. |
| Red blood cell | Carries oxygen. Hemoglobin. Gas exchange to provide oxygen for tissues/muscles. |
| Surfactant | create a surface that allow better environment of diffusion and like moisture and flexibility |
| Parietal Cell | Secretes pepsinogen in gastric pits to form pepsin |
| Chief Cell | Secretes acid in gastric pits to form pepsin. |
