Loading flashcards...
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
