1

Body systems

skeletal, muscular, nervous, endocrine, cardiovascular, respiratory, digestive, urinary, reproductive, immune, integumentary

2

Types of tissues

- epithelial = layers of cells lining a surface (e.g. skin)
- connective = extracellular matrix (e.g. bones, cartilage, fat)
- muscle = e.g. skeletal, smooth, cardiac
- nervous = e.g. brain, spinal tissue, nerves

3

Metabolism

- catabolism = breakdown of large complex molecules into smaller ones
- anabolism = uses energy to build body’s structural and functional components

4

Life processes

- metabolism, responsiveness, movement, growth, differentiation, reproduction

5

Intracellular to extracellular examples

- from lumen of digestive tract to tissues
- respiratory system (alveoli to blood)

6

Homeostasis elements

- change in a variable
- sensor/receptor
- integrator/control system
- effector
- response
- controlled variable back to normal

7

Types of homeostasis mechanisms

- negative feedback (e.g. baroreceptors)
- positive feedback (e.g. childbirth)
- feedforward (e.g. ready for digestion)
