What a structure can do depends on its specific form.

• Chemicals– Atoms– Molecules

• Cellular– Organelles– Variety of shapes and functions

• Tissue– Epithelium– Connective– Muscular– Nervous

Levels (Continued)

• Organs– Heart– Brain

• Organ Systems– Integumentary– Skeletal– Muscular– Nervous– Endocrine

Levels (Continued)

• Organ System (Continued)– Cardiovascular– Lymphatic– Respiratory– Digestive– Urinary– Reproductive

• Organism

• Maintain Boundaries• Movement• Responsiveness• Digestion• Metabolism• Excretion• Reproduction• Growth

• Nutrients

• Oxygen

• Water

• Temperature

• Pressure– Atmospheric– Hydrostatic

Homeostasis

• Stable internal environment

• Control Mechanism– Receptor– Control Center– Effector

Homeostasis (Continued)

• Types of Regulation– Autoregulation– Extrinsic Regulation

Homeostasis (Continued)

• Homeostatic feedback– Positive Feedback

• Enhances (Strengthens) the stimulus• Change proceeds in same direction as original

change.

– Negative Feedback• Most feedback mechanisms• Reduces the stimulus• Change proceeds in the opposite direction as

original change.
