The document discusses anatomy and physiology. It defines anatomy as the study of the structure of the body and its parts and their relationships. Physiology is described as the study of the normal functions of the body. It notes that anatomy and physiology are always related, as the structure of each body part determines its function. The document then lists and provides brief descriptions of the 11 organ systems in the human body. It concludes by discussing how homeostasis and feedback mechanisms allow the organ systems to work cooperatively to maintain a stable internal environment.

1. What is Anatomy and
Physiology?

2. What is Anatomy?
• Anatomy is the study of the
structure of the body and body
parts and their relationship to one
another
– Ex. The structure of the heart

3. What is Physiology?
• Physiology describes the normal functions
of the body
– Ex. How is blood pumped by the heart and
circulated throughout the body

4. Anatomy & Physiology Relationship
• In the real world, anatomy and physiology are
always related.
• The each of the body parts have a job to do
based on their structure.

5. Heart??

6. Reality Check!!

8. Try and write down as many organ
systems as you can!
(There are 11)

9. Organ Systems
1. Integumentary
2. Skeletal
3. Muscular
4. Nervous
5. Endocrine
6. Cardiovascular
7. Lymphatic/Immune
8. Respiratory
9. Digestive
10. Urinary
11. Reproductive

11. Integumentary System
• Skin, hair
– Provides external protection
– Sweat glands, pores, pain
receptors

12. Skeletal System
• Bones, cartilage, joints
– Protects and supports organs
– Provides framework for muscles

13. Muscular System
• Muscles
– Allows manipulation of environment and
movement; facial expressions, maintains posture
and produces heat

14. Nervous System
• Brain, sensory receptor,
Spinal cord, nerves etc…
– Control of body systems,
responds to internal and
external changes

15. Endocrine System
• Glands, pancreas, testis, ovary and hormones
– Secretes hormones that regulate processes such
as growth, reproduction and metabolism

16. Cardiovascular System
• Heart and blood vessels
– Carries oxygen, carbon dioxide

17. Lymphatic/Immune System
• Lymphatic vessels, lymph nodes, tonsils,
spleen etc…
– Houses white blood cells, removes debris in
lymphatic stream

18. Respiratory System
• Lungs, trachea, larynx, pharynx, nasal cavity,
bronchus etc…
– Keeps blood supplied with oxygen and removes
carbon dioxide

19. Digestive System
• Oral cavity, esophagus, stomach, intestines,
rectum, anus etc..
– Breaks down food, waste disposal

20. Urinary System
• Kidney, ureter, urinary bladder, urethra
– Eliminates wastes from the body; regulates
balance of blood.

21. Reproductive System
• Male: Seminal vesicles, prostate gland, vas
deferens, penis, testis, scrotum
• Female: Mammary glands(in Breasts), Uterine
tube, ovary, uterus, vagina
– Produce offspring via sexual reproduction.

22. If you had to pick one body system to
live without, what would it be and
why?

23. Cooperation
• In order to maintain a well-functioning body,
the systems have to work together to maintain
Homeostasis
– One relies on the other for support or guidance

24. Homeostasis
• The body’s ability to maintain a relatively
stable internal environment despite the
constant external changes.

25. Homeostasis

26. (-) Negative Feedback
• Most common response(output)
• Shuts down or reduces stimulus
– Example: Thermostat in heating systems
– Hypothalamus

27. (+) Positive Feedback
• Very rare in the human
body
– Increase original stimulus
– Usually used to control
infrequent events that do
not require constant
adjustment.
• Examples: Blood Clotting,
birth of a baby
