Homeostasis. The biological definition of homeostasis is âthe tendency of an organism or cell to regulate its internal environment and maintain equilibrium, usually by a system of feedback controls, so as to stabilize health and functioningâ.ositive feedback mechanisms. A positive feedback mechanism is the exact opposite of a negative feedback mechanism. With negative feedback, the output reduces the original effect of the stimulus.
Bacteria produce disease in one of two general ways; some bacteria damage the cells and tissues of the infected organism directly by breaking down the cells for food, other bacteria release toxins (poisons) that travel throughout the body interfering with the normal activity of the host. Pathogens.
Report Abuse. Bacteria don't enter cells, - that's viruses. In general: Bacteria kill and eat cells by releasing enzymes that 'digest' the cell and allow the bacteria to absorb the nutrients released. Since those enzymes destroy tissue they are poisons.The higher the number of bacteria living in the body, the greater the concentration of those poisons in the blood. KNOW it destroys tissue causing organ failure, usually in the lungs. So DONT tell me you die by suffocating I want to know how having TB bacteria in your cells results in tissue death.
