A&P Chapter 1

The study of structure of the human body and the relation of its parts. It is largely based on dissection.

Examined with the unaided eye.

Examined with a microscope.

The study of cells.

The study of tissues.

Part of the embryology and gerontology.

The study of structure in various animal species.

The study of the normal functions of a human body.

The study of disease, or the disruption of normal body function.

• Atom - nitrogen, oxygen, sodium, etc.
• Molecule - NH₂-CH₂-COOH, amino acid
• Organelle - proteins filaments
• Cells - muscle cells
• Tissue - cardiac muscle
• Organ - heart
• System - cardiovascular system
• Organism - human being

Protects from environmental changes, involved in temperature control, vitamin D3 production and sensory information.

Supports, protects, blood production, Ca²⁺, mineral storage.

Supports, moves and provides heat.

Coordinates immediate activites of body systems and responses to stimuli.

Coordinates long-term activities of body systems using hormones.

Transports nutrients, wastes, electolytes and gases.

Defends against disease and moves lymph (water and proteins) from periphery back to cardiovascular system.

Filters, warms air and provides site for gas exchange between the air and blood.

Processes and absorbs food, water, minerals and vitamins.

Eliminates excess water, H⁺ ions, electrolytes, and waste products.

Produces sex cells and hormones.

• Homeo = Same
• Stastis = Level, standing

• The body's ability to maintain body functions within normal limits. The maintenance of a relatively constant internal environment is usually achieved through negatiive feedback.
• Ex. Body temp. Blood Pressure, pH, Glucose
