1. The Systems of the Human Body
Can you guess how many different system make up the Human Body?
Well….the correct number is 11!! 11 different systems all working together for you to function.
How many do you know out of those 11?
We will go over all 11 in today’s lecture!

2. Levels of Organization
Lets review…What are the levels of organization within a single human body??
Atoms/Molecules
Cells
Tissues
Organs
Systems
Organisms/Individual

3. Integumentary System
Integumentary System

4. Integumentary System
Skin, hair, nails, sweat glands, and sebaceous glands.
Protect underlying tissue, help regulate temp, sensory receptors, and synthesize certain products.

5. Integumentary System

7. Bones, ligaments, tendons, and cartilage.
Provides frameworks, protective shield for softer tissue, attachment for muscles, and act together with muscles for movement
Tissue within the bones produce blood cells, store inorganic salts.

8. MUSCULAR SYSTEM
                                  

9. MUSCULAR SYSTEM All muscles… Smooth, cardiac, and skeletal..
Force for body movement, help maintain posture, are the main source of body heat.
Aids in circulation of blood and food throughout the body.

10. NERVOUS SYSTEM

11. NERVOUS SYSTEM Brain, spinal cord, nerves, and sense organs.
Nerve cells send nerve impulses
Specialized sensory receptors.
Some nerves receive/send impulses
Some carry impulses from the brain or spinal cord to muscles

12. NERVOUS SYSTEM The basic unit of the nervous system are neurons.
There are 3 types: sensory, motor, and interneurons!

13. ENDORCRINE SYSTEM

14. ENDORCRINE SYSTEM
Function: Controls growth, development, and metabolism.
Maintains Homeostasis
ORGANS- Pituitary, thyroid, parathyroid, and adrenal glands, pancreas, ovaries, testes, pineal gland, and thymus gland

15. CARDIOVASCULAR SYSTEM

16. CIRCULATORY SYSTEM
Includes heart, arteries, veins, capillaries, and blood
Heart-pump that forces blood through blood vessels.
Blood- carries oxygen from lungs and nutrients from digestive organs to all body cells

17. CIRCULATORY SYSTEM Heart-pump that forces blood through blood vessels.
Blood- carries oxygen from lungs and nutrients from digestive organs to all body cells
These are red blood cells!
They are the most numerous cells in the body.
These cells transport oxygen.
The cells actually have no nuclei.
They live in the human body for about 120 days!

18. Lymphatic/Immune System

19. Lymphatic/Immune System
Function: Helps to protect the body from disease
Collects fluid lost from blood vessels & returns the fluid to the circulatory system.
Structures: White blood cells, thymus, lymph nodes, lymph vessels

20. Digestive System
                                                       

21. Digestive System
Includes: Mouth, tongue, teeth, salivary glands, pharynx, esophagus, stomach, liver, gallbladder, pancreas, small and large intestine
Breaks down food to similar forms that can pass through cell membranes to be absorbed. .

22. Digestive System
Materials not absorbed are transported back outside the body. (Primarily the job of your colon)
Certain digestive organs produced hormones and function as part of the endocrine system.

23. The Respiratory System
                                                          

24. The Respiratory System
Includes: Nasal cavity, pharynx, larynx, trachea, bronchi, and lungs
Function: Takes air in and out and exchanges gases between blood and the air. (O2 in and CO2 out )

25. Excretory/Urinary System

26. Excretory/Urinary System
Primarily includes kidney, ureters, urinary bladder, and uretha
Some resources include lungs & skin
Kidneys remove wastes from blood and assist in maintaining the body’s water and electrolyte balance
Product is urine  

27. Reproductive System

28. Reproductive System Female
Ovaries, uterine tubes, uterus, vagina, clitoris, vulva
Function: Produce and maintain egg cells, receive sperm cells, support development of an embryo and function in birth process

29. Reproductive System Male
Scrotum, testes, epididymides, vasa deferentia, seminal vesicles, prostate gland, bulbourethral glands, urethra, and penis
Function: Produce and maintain sperm cells, transfer sperm cells into female reproductive organs.
