Introduction: Anatomy

Study of the structure of living organisms surface anatomy gross anatomy embryology cytology histology

Physiology

Study of the function of body parts cell physiology pathophysiology exercise physiology immunology

Body Systems Integumentary system- external

support and protection of the body Skeletal system - internal support

and flexible framework for body movement

Muscular system - production of body movement and body heat

Respiratory system- gas exchange between environment and blood

Nervous system- controls and regulates all other systems of the body

Circulatory - transport of nutrients to body cells and waste products away from cells

Lymphatic system- body immunity and absorption of fats

Endocrine system- secretion of hormones

Urinary system - blood filtration and waste removal

Digestive system- breakdown and absorption of food

Reproductive system - production of egg and sperm as well as secretion of the sex hormones

Organization of Life

Structural Levels chemical cellular tissue organs organ systems

What is Life?Characteristics of Life

Organization Metabolism

catabolism anabolism

Responsiveness

Movement Growth Differentiatio

n Reproduction Homeostasis

“Homeostasis”

Constancy Within Narrow Limits

Feedback Loops

Negative feedback systems reverses original stimulus helps stabilize situation

Positive feedback systems enhancement of original stimulus

amplify/reinforce change
