Human Biology Exam

TermDefinition
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.
