Anatomy and Physiology
Turn to a neighbor and talk about:
 What you think you will learn about in this class
 The definition of anatomy
 The definition of physiology
Biology
 Study of life
 Requirements:
1. Water
2. Food
3. Oxygen
4. Heat
5. Pressure
 Functions:
1. Responsiveness
2. Growth
3. Reproduction
4. Movement
5. Metabolism (Respiration, Digestion, Excretion, etc.)
Anatomy
 “a cutting open” in Greek
 Studies the field of structure (morphology)
Physiology
 Studies the performance or function
Anatomy and Physiology
 “Form and Function”

Reproductive (male and female)
Integumentary
 Epidermis (skin), hair, nails
 Protects against environmental hazards, controls body temp
Skeletal System
 Bones, cartilage
 Provides support, protects tissues, stores minerals, forms
blood
Muscular System
 Muscles, tendons
 Allows locomotion, provides support, produces heat
Nervous System
 Nerves, brain, spinal cord
 Directs immediate response to stimuli, usually coordinates
activities of other systems
Endocrine System
 Glands
 Directs long-term changes in activities of other organ
systems
Cardiovascular System
 Heart, blood vessels, blood
 Transports cells and dissolved materials (nutrients, wastes,
gases)
Lymphatic System
 Lymphatic vessels and nodes, spleen, thymus
 Defends against infection and disease, returns tissue fluid to
bloodstream
Respiratory System
 Nasal cavities, pharynx, larynx, trachea, bronchi, lungs
 Delivers air to sites where gas exchange can occur between
the air and circulating blood
Digestive System
 Salivary glands, pharynx, esophagus, stomach, intestine, liver,
gallbladder, pancreas
 Processes food and absorbs nutrients
Urinary System
 Kidneys, ureters, urinary bladder, urethra
 Eliminates excess water, salts and waste products
Reproductive System
 Male: testes, accessory organs, external genitalia (penis,
scrotum)
 Female: ovaries, uterine tubes, uterus, vagina, external
genitalia (clitoris, labia), mammary glands
 Produces sex cells and hormones
