Define and describe human anatomy and physiology?

Human Anatomy is the structure both macroscopic and microscopic.

Physiology is the study of how these structures work and function.

1. Atoms/molecules
2. Cells
3. Tissues
4. Organs
5. Body Systems
6. Whole Body

The Circulatory System - heart, blood vessels and blood.

Transport of materials, such as nutrients, O2, CO2, wastes, electrolytes and hormones to every part of the body.

The Respiratory System - Lungs, and major airways

Receives O2 and eliminates CO2.  Adjusts the rate of removal of CO2 and is important in maintaining pH levels.

The Urinary System - Kidneys and associated plumbing.

Removes excess water, salt, acid and other electrolytes in the urine.

Identify the 11 body systems and their role in Homeostasis

2.

The Skeletal System - Bones and Joints

Supports and Protects tissues and organs, stores Ca, maintains plasma concetrations, new blood cells from bone marrow.

The Muscular System - Movement and Heat regulation.

The Integumentary System - Skin and related structures.

Protective barrier, prevents loss of internal fluids and organelles, prevents foreign microorganisms entering the body, regulates temperature.

The Immune System - Lymphatic and white blood cells.

Defends against foreign invaders, helps in the replacement of damaged cells.

Identify the 11 body systems and their role in Homeostasis

3.

The Nervous System - Brain, Spinal Cord, nerves and sense organs.

Controls and coordinates activities that require swift responses, Detects Changes in esternal environment.

The Endocrine System - All hormone secreting glands etc.

Regulates activities that require duration not speed.  Controls concentration of nutrients and by adjusting kidney function, controls volume and electrolyte composition of ECF.

The Reproductory System - male and female gondas and related organs.

Not essential for homeostasis but is essential for survival of the human race.

Intrinsic - local, built into or are inherint to the organ, maintains homeostasis within itself.

Extrinsic - Outsited the organ ie. nervous and endocrine.  Controls from outside the organ and can override intrinsic control.  Coordinates several organs at ones ie to restore blood pressure when it is low it will act simultaneously on the heart and blood vessels.
