8 Necessary Life Functions
1. Maintaining boundaries between external/internal environments
2. Movement
3. Responsiveness
4. Digestion
5. Metabolism
6. Excretion
7. Reproduction
8. Growth
38
1. Maintaining boundaries between internal/external environments (homeostasis)
Examples:
- Skin
- Cell Membrane
39
2. Movement (contractility)
- Skeletal muscle contraction
| - Of substances (cardiac and smooth muscle)
40
3. Responsiveness
- Ability to sense and respond to stimuli
- Withdrawal reflex
- Reflex control of breathing
41
4. Digestion
- Breakdown of ingested foodstuffs
| - Absorption of simple molecules into blood
42
5. Metabolism
-All chemical reactions that occur in body cells (Anabolism, Catabolism)
43
Catabolism
Break down of larger molecules into smaller molecules
44
Anabolism
Use of energy to construct larger molecules from smaller ones
45
6. Excretion
- Removal of wastes form metabolism
| - Urea, carbon dioxide, feces
46
7. Reproduction
- Production of offspring
| - Cellular division for growth or repair
47
8. Growth
-Increase in size of a body part or of an organism
48
Feedback Control Loops
- Receptor (sensor)
- Control center
- Effector
49
Receptor (sensor)
- Monitors environment
| - Responds to stimuli
50
Control Center
- Receives input from receptor
| - Interprets signal, and determines appropriate response
51
Effector
- Receives output from control center
- Provides the means to respond
- Response either: positive or negative
