Chapter 1:
The Human Body
-Homeostasis: process by which the body’s internal environment is kept
stable in spite of external changes
-4 levels of organization: cells, tissues, organs, organ systems
Cell: basic unit and building block of all life
Tissue: group of similar cells that perform the same function
4 types: muscle, connective, nerve, epithelial
Organ: a group of different tissues with a specific job
Organ systems (11) see chart pg 22: a group of organs that
work together to do a specific job
-homeostasis lab: influence of exercise on:
skin color, perspiration, external body temp, heart rate, breathing
rate
-chicken wing lab: role of nerves, muscle, tendons, ligaments, fat, skin
Chapter 8:
Body defenses:
1st line: skin, body openings (general)
2nd line: inflammatory response (general) histamines, fever, interferon
3rd line: antibodies (very specific) puzzle analogy & key/lock analogy
-role of antigens, T cells (infantry), B cells (artillery)
Immunity:
Active (you make antibodies) get disease or vaccination
Passive(you don’t make antibodies) flue shot
Allergies: role of histamines and allergens
Infectious diseases: caused by microorganisms
Noninfectious: not caused by microbes (ie cancer, diabetes, genetic
problems)
Pathogens
Vectors (air, water, food, insects& animals, person to person)
Immune system film:
-how do bacteria develop resistance
-reasons why antibiotics have become a problem
