工作细胞/Cell at Work （read until Vol. 5）
👼原来大肠里除了有好菌和坏菌之外，还有Opportunistic bacteria，它们没帮好菌或坏菌，但任何一方对它们有好处，那它们就帮那一方，感觉有点像墙头草。 .
👽Hemolysis: Destruction of RBC
👽Phagocytosis: The process by which a cell engulfs and breaks down bacteria and foreign substances. Cells that can do this ( exp. Monocytes, macrophages and neutrophils) are called phagocytes
👽B Cell (Antibody-producing Cell): produce IgE Antibody
👽Mast Cell: releases chemicals such as histamines and leukotrienes in response to stimulus from excessive production of IgE
👽Myelocyte: a cell that has yet to differentiate to a WBC (neutrophil, eosinophil/basophil)
👽NK Cell (Natural Killer Cell): patrols whole body for cancerous/ virus-infected cells to attack
👽Metastasis: cancer cell travel across body in bloodstream and lymphatic system to spread their activity
👽T Cell Precursor >> Thymocyte >> Naïve T Cell >> Killer T Cell
👽Staphylococcus Aureus (金黄色葡萄球菌): Bacteria love on skin and pores. Highly virulent and can cause condition exp skin infection, food poisoning, pneumonia, meningitis (脑膜炎) and sepsis (脓血症) if they enter body through wound
👽Langerhands Cell: Signaling brain when foreign substances such as bacteria and virus enter bpdy and protecting skin against ultraviolet rays and dehydration
👽Hypovolemic Shock: massive bleeding due to injury to blood vessels or digestive tract can cause loss of blood pressure lead dizziness/fainting
👽Peye’s Patch: An immune tissue in small intestine, common in between villi or where villi are scarce. It is filled with lymphoid nodules and plays an important role in immune response of intestines. M cell live here (captured bacterial and viruses handed over to dendritic cells and presented as antigens)
👽Lactic Acid Bacteria: produce lactic acid to break down sugar to live. Byproduct is lactic acid may cause some bacteria weak. Some Lactic Acid Bacteria break down purines into form that less absorbable by human and ingest it into bodies as nutrients.
