Homeostasis?
All body systems work together to maintain a stable internal environment
Negative feedback
Body brought back into homeostasis
Positive feedback
Body is moved away from homeostasis
3 homeostatic regulatory mechanisms?
Receptor, control center, effector
3 types of muscle tissue
Skeletal, cardiac, smooth
4 types of tissue
Epithelial, connective, muscle, nervous
Define membrane potential
When positive and negative charges are separated, a potential difference is created
Cytoskeleton
Provide strength
Ribosomes
Synthesis proteins
Endoplasmic reticulum
Synthesis of proteins, carbs, lipids
Transportation
Golgi apparatus
Modifies and packages secretions
Lysosomes
Destroy bacteria
Mitochondria
Produce energy by ATP
Nucleus
Controls the cell
Define osmosis
Diffusion of water from one solution to another solution that contains a higher solute concentration
