1 Anatomy and Physiology

2 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

3 Biology Study of life Requirements: Functions: Water Food Oxygen Heat
Pressure Functions: Responsiveness Growth Reproduction Movement Metabolism (Respiration, Digestion, Excretion, etc.)

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

5 Physiology Studies the performance or function

6 Anatomy and Physiology
“Form and Function”

7 Levels of Organization and Organ Systems


9 Levels of Organization
Chemical/Molecular Cellular Tissue – cells performing specific function Organ – tissues performing specific function Organ System Organism

10 How many organ systems can you name?

11 Organ Systems Integumentary Skeletal Muscle Nervous Endocrine
Cardiovascular Lymphatic Respiratory Digestive Urinary Reproductive (male and female)

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

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

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

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

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

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

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

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

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

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

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

23 Homework Coloring Workbook – Chapter 1 Numbers 3-7 and #20
Cross off #9 – we will not be doing that question An Introduction to Anatomy and Physiology – Chapter 1 Objectives 1-4
