Slide 1

Anatomy and Physiology

Slide 2

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

Slide 3

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.)

Slide 4

Anatomy a cutting open in Greek Studies the field of structure (morphology)

Slide 5

Physiology Studies the performance or function

Slide 6

Anatomy and Physiology Form and Function

Slide 7

Levels of Organization and Organ Systems

Slide 8

Slide 9

Levels of Organization 1. Chemical/Molecular 2. Cellular 3. Tissue cells performing specific function 4. Organ tissues performing specific function 5. Organ System 6. Organism

Slide 10

How many organ systems can you name?

Slide 11

Organ Systems 1. Integumentary 2. Skeletal 3. Muscle 4. Nervous 5. Endocrine 6. Cardiovascular 7. Lymphatic 8. Respiratory 9. Digestive 10. Urinary 11. Reproductive (male and female)

Slide 12

Integumentary Epidermis (skin), hair, nails Protects against environmental hazards, controls body temp

Slide 13

Skeletal System Bones, cartilage Provides support, protects tissues, stores minerals, forms blood

Slide 14

Muscular System Muscles, tendons Allows locomotion, provides support, produces heat

Slide 15

Nervous System Nerves, brain, spinal cord Directs immediate response to stimuli, usually coordinates activities of other systems

Slide 16

Endocrine System Glands Directs long-term changes in activities of other organ systems

Slide 17

Cardiovascular System Heart, blood vessels, blood Transports cells and dissolved materials (nutrients, wastes, gases)

Slide 18

Lymphatic System Lymphatic vessels and nodes, spleen, thymus Defends against infection and disease, returns tissue fluid to bloodstream

Slide 19

Respiratory System Nasal cavities, pharynx, larynx, trachea, bronchi, lungs Delivers air to sites where gas exchange can occur between the air and circulating blood

Slide 20

Digestive System Salivary glands, pharynx, esophagus, stomach, intestine, liver, gallbladder, pancreas Processes food and absorbs nutrients

Slide 21

Urinary System Kidneys, ureters, urinary bladder, urethra Eliminates excess water, salts and waste products

Slide 22

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
