Immune System- Giselle Zepeda p.2
Major functions of lymphatic system
Location of Lymphatic organs and their functions
Purpose and examples of 1st, 2nd, & 3rd line of defense
Major functions of immune system
Innate & Adaptive
Antigens & Antibodies
Cells involved in the immune system & their functions
Humoral response and cellular response
Passive vs. Active immunity & artificial v natural
Disorders associated with the Immune system
Thymus
Lymphatic Vessels
Spleen
Lymph Nodes
Located in throat, armpits, chest, abdomen and groin. Function is to defend against bacteria
Found everywhere, takes the lymph back to the lymph nodes
inside the ribcage & behind the breastbone, it produces t cells
Located on the left abdominal side, it filters and monitors our blood
Antibodies: a protein produced to attack and fight off the antigens
Antigen: bacteria, fungi, viruses, allergens, venom & other toxins
recognizes and acknowledges harmful factors of the environment
Also fights off cancer cells
Fight off bacteria and diseases mainly pathogens
deals with cell products that would result in diseases
Absorbs some fat from our intestine
deals with cancer cells
reacts to bacteria
Manages fluid levels in the body
eosinophils & Basophils- important for defense against parasites & allergic reactions
neutrophils- circulate in bloodstream and patrol for problems
Humoral: Produces antigen specific antibodies. example: the mother's antibodies are passed to the baby
Cellular: Responds to extracellular signals. Important bc it helps body maintain homeostasis
- Mucous, tears, skin help protect us against invading pathogens
- Eosinophils,neutrophils, basophils. Destroys invaders without targeting specifics
- Interlukin. They get rid of the microorganisms that have ruined our tissue
Passive- immunity from something/someone else
Active- immunity from vaccines/infections
Natural-antibodies made after fighting off an infection
Artificial- antibodies made after getting a vaccine
Artificial- Acquired from an immune serum medicine
Natural- from mother to baby
Adaptive(acquired) immune defenses: Helper T cells, Cytotoxic cells, and B cells
Innate (natural) immune defenses: leukocytes, dendritic cells, natural killer cells, and plasma proteins
Enterobiasis- White, parasite worms that live in the large intestine of humans
Malaria- Feverish illness that is spread to people through the bites of infected female mosquitos
Toxoplasmosis- Food born illness, parasite called toxoplasma gondii
Cholera- Diarrheal illness, extremely virulent disease
Hepatitis B- Vaccine preventable liver infection caused by HBV
Polio-infects spinal cord which causes paralysis
