A B; immune system: body system that fights off infections: phagocyte: cell that destroys other cells by surrounding and engulfing them: T cell: white blood cell that matures in the thymus and destroys infected body cells by causing them to burst; also called a T-lymphocyte
31.2 Immune System Many body systems protect you from pathogens. • The immune system is the body system that fights off infection and pathogens. • Many other tissues and systems help
Destroys pathogens in one of three ways: 1. Might make the pathogen ineffective by binding to the pathogens membrane proteins 2. Might cause pathogens to clump, making them easier for phagocytes to engulf and destroy 3. Other antibodies activate complement proteins that weaken the pathogens cell membrane

immunity that occurs without the body undergoing an immune response. Transferred through DNA and between mother and child. Occurs because pathogen is not specialized to harming that species.
fluid found within lymphatic vessels formed from blood plasma as blood flows thru blood capillaries, hydrostatic and osmotic pressures filter more plasma out of the blood capillary and into the interstitial spaces than is drawn back inside. --> excess fluid in the interstitial spaces is called interstitial fluid and when interstitial fluid enters the lymphatic capillaries its called lymph
The immune system consists of organs, cells, and molecules that fight infections. MAIN IDEA: Many body systems protect you from pathogens. 1. What is the immune system? 2. For each, describe how it helps the immune system by protecting the body from pathogens. Tissue or Body System How It Protects the Body from Infection skin mucus membrane
3rd line of defense- immune system must be able to distinguish between its own body cells and invading cells. What characteristics do the first line of barriers have? They are physical and/or chemical nonspecific defenses. physical ex- tough outer layer of dead cells (on skin), chemical ex- sweat and oil glands
division of the immune system; provides highly specific defense adjacent particular macromolecules present in particular pathogens referred to as antigens sometimes called acquired immune system - new immunities gained over time; only possessed by
Identify the main organs and cells of the immune system, and explain their functions. Compare and contrast the innate and adaptive immune responses, and explain how they interact. Explain the role of memory cells when the body responds to a pathogen it has previously encountered, and apply this knowledge to the function of vaccines.
Why doesn''t our immune system destroy our own cells? Answer: Major Histocompatibility Complex (MHC): • Unique set of proteins / polysaccharides which identify "self" cells of body • Act as antigens in other individual''s bodies Chapter 31: Immune System Fundamental Steps in Immune Response: 2) Immune system must launch attack...

The central nervous system consists of the brain and spinal cord. The brain controls functions like learning, judgment, emotion, behavior, and memory through regions like the cerebrum, limbic system, thalamus, and hypothalamus. Addiction occurs when drugs cause increased dopamine release in the brain, leading the brain to reduce dopamine receptors over time so larger drug
