4. Anatomy and Physiology
Structures
Shape of the body and its parts
Gross Anatomy can be seen without a microscope
Microscopic , too small to be seen without a microscope
How the body and its parts work
Structures determine the function
Functions are the processes or jobs

5. Levels of Organization

6. Skeletal Muscular Cardiovascular Nervous Endocrine Integument
11 Systems
Skeletal
Muscular
Cardiovascular
Nervous
Endocrine
Integument
Respiratory
Digestive
Urinary
Lymphatic / Immune
Reproductive

7. Skeletal System Structure Function
Bones, cartilage, ligaments and joints
Function
Support.
Provides basis for movement.
Protection
Hematopoiesis = Formation of red blood cells happens within long bones.
Mineral storage.

8. Muscular System Structure Function
Skeletal muscles. Although muscle is found in other systems
Muscles contract (shorten) and provide movement.
Support.
Heat production

9. Cardiovascular System
Structure
Heart and blood vessels.
Function
Uses blood as the carrier of nutrients, wastes and gasses
Carries White Blood Cells and chemicals that protect the body
Heart acts as a pump .

10. Lymphatic / Immune System
Function
Structure
Lymphatic vessels, Lymph nodes, spleen tonsils, thymus, bone marrow,
Recovers fluids for tissue drainage
Cleans the blood
Houses cells that are involved in immunity

11. Nervous System Function Responds to external and internal signals
Structure
Brain, spinal cord, nerves, sensory receptors
Responds to external and internal signals
Coordinates activities of other organ systems.

12. Endocrine System Structure
Pituitary, Thyroid, Parathyroid, Adrenals, Thymus, Pancreas, Pineal, Ovary and Testes.
Function
Directs long-term changes using hormones.
Growth,
Reproduction
Food Use.

13. Integumentary System Structure
Skin (largest organ) and temperature, pressure and pain receptors.
Function
Protect,
Cushion
Waterproofs
Excretes salt and urea
Regulates temperature.

14. Respiratory System Structure Function
Nasal passage, pharynx, larynx, trachea, bronchi, lungs
Function
Delivery of air to sites where gas exchange takes place

15. Digestive System Function
Processing food, absorption of organic nutrients, minerals vitamins and water
Structure
oral cavity,
esophagus
stomach
small
large intestines
rectum
liver
pancreas

16. Urinary System Structure Kidneys, ureters, bladder, urethra. Function
Excretes nitrogen-containing waste (forms when protein is broken down) Urea and Uric Acid
Maintains water and salt balance
Controls pH of the blood

17. Reproductive System Function
Structure
Function
Production of sex cells and hormones to produce offspring.
M=Testes (produce sperm), Scrotum, Penis accessory glands and duct system
F=Ovary Produce eggs), Uterine tubes, Uterus, Vagina

18. 8 Life Functions
Boundaries: Inside is separate from outside…every cell has a membrane.
Movement: We move and our food moves through us.
Responsiveness: Sense changes and react.
Digestion: Breaking down of food to be absorbed by blood.
Metabolism: All chemical reactions in the body. Depends on the Digestive and Respiratory systems for nutrients and oxygen but it is regulated by the hormones of the Endocrine system.
Excretion: Removing waste
Reproduction: Production of offspring
Growth: Increase in size.

19. Homeostasis
Stable internal conditions
Homeostatic Control Mechanisms

20. Negative Feedback Mechanisms
Shuts off original stimulus like home thermostat.
Our body has a lot of these: Water, temperature, sugar, fight or flight, muscles for balance. Constant state of adjustment.

21. Positive Feedback Mechanisms
Increases the original stimulus. Blood clotting and birth of baby.

23. Anatomical Position
Body erect, feet parallel, arms at sides palms forward. Use the face of the clock to describe location
