1. The Human Body Systems

2. Circulatory System
Transport materials to and from cells

3. Circulatory System Organs
Heart
Veins
Arteries
Capillaries
Red blood cells

4. Respiratory System
Takes in oxygen and removes carbon dioxide and water

5. Respiratory System Organs
Nose
Trachea
Bronchi
Bronchioles
Alveoli
Lungs

6. Digestive System Take in food (ingestion)
Digest food into smaller molecules and absorb nutrients
Remove indigestible food from body (feces)

7. Digestive System Organs
Mouth,
Rectum, Anus
Esophagus
Salivary glands
Stomach
Small Intestine
Pancreas,
Liver
Large intestine
Gall bladder

8. Endocrine System
Regulates body activities using hormones. Slow response, long lasting

9. Endocrine System Organs
Glands
Hypothalamus
Pituitary
Thyroid
Thymus
Adrenal
Pancreas
Ovaries
Testes
Glands produce Hormones

10. Nervous System Gathers and interprets information
Responds to information
Helps maintain homeostasis

11. Nervous System Organs Brain Spinal cord Nerves Nerve cells = neurons
Hypothalamus

12. Muscular System
Allows for movement by contracting

13. Muscular System Organs
Cardiac muscle
Smooth muscle
Skeletal muscle
Tendons

14. Skeletal System Protects organs Provides shape, support
Stores materials (fats, minerals)
Produces blood cells
Allows movement

15. Skeletal System Organs
Bones
Cartilage
Ligaments

16. Excretory System Removes waste products from
cellular metabolism (urea, water, CO2)
Filters blood

17. Excretory System Organs
Kidneys
Ureters
Bladder
Urethra
Lungs
Skin – sweat
glands
Liver (produces urea)

18. Integumentary System Barrier against infection (1st line of defense)
Helps regulate body temp.
Removes excretory waste (urea, water)
Protects against sun’s UV rays
Produces vitamin D

19. Integumentary System Organs
SKIN
Epidermis
Dermis
Sweat gland
Sebaceous gland (oil)
Hair follicle
Blood
Vessels
Nerves

20. Immune System
Fights off foreign invaders in the body

21. Immune System Organs White Blood Cells Macrophages Skin T cells
B cells
Produce antibodies
Macrophages
Skin

22. Lymphatic System Stores and carries WBC’s that fight disease
Collects excess fluid and returns it to blood (2nd circulatory system- Reaches places other one can’t; between cells)

23. Lymphatic System Organs
Lymph (liquid part of blood - plasma, when it’s in lymph vessels)
Lymph Vessels
Lymph Nodes
Contain WBCs

24. Reproductive System
Allows organisms to reproduce which prevents their species from becoming extinct.

25. Reproductive System Organs
Ovaries
Produce eggs
Testes
Produce
Sperm

26. System Interactions

27. Circulatory System Interactions
w/respiratory – deliver O2 from lungs to cells and drop off CO2 from cells to lungs
w/digestive – absorb and deliver digested nutrients to cells
w/excretory – kidneys filter cellular waste out of blood for removal
w/lymphatic – both transport things to and from cells
w/immune – transports WBCs throughout body to fight disease
w/nervous – brain controls heartbeat
w/endocrine – trans. hormones

28. Respiratory System Interactions
w/circulatory – takes in O2 for delivery to cells and removes CO2 brought from cells
w/excretory – removes excretory waste
w/nervous – controls breathing
w/muscular – diaphragm controls breathing

29. Digestive System Interactions
w/circulatory – absorb & deliver the digested nutrients to the cells
w/muscular – control the contractions of many of the digestive organs to pass food along
w/nervous – hypothalamus maintains homeostasis by triggering appetite (stomach growling), digest.

30. Endocrine System Interactions
w/circulatory –transports hormones to target organs
w/nervous – maintain homeostasis, hormone release
w/reproductive – controlled by hormones
w/skeletal – controls growth of bones

31. Nervous System Interactions
Controls all other systems
Hypothalamus – maintains homeostasis by working with all systems

32. Muscular System Interactions
w/skeletal – allow movement
w/digestive – allow organs to contract to push food through
w/respiratory – diaphragm controls breathing
w/circulatory – controls pumping of blood (heart)
w/nervous – controls all muscle contractions

33. Skeletal System Interactions
w/muscular – allow movement
w/circulatory – produce blood cells
w/immune – produce white blood cells
w/circulatory and respiratory – protects it’s organs

34. Excretory System Interactions
w/circulatory – filters waste out of blood
w/lungs – removes excretory waste
w/integumentary – removes excretory waste

35. Integumentary System Interactions
w/excretory – removes cellular waste
w/nervous – controls body temperature (sweating, goose bumps)
w/immune – prevents pathogens from entering

36. Immune System Interactions
w/circulatory – transports WBCs to fight invaders
w/lymphatic – has lots of WBCs to fight invaders, spleen filters bacteria/viruses out of blood
w/skeletal – WBCs made in bone marrow
w/integumentary – prevents invaders from getting in

37. Lymphatic System Interactions
w/immune – holds lots of WBCs to fight pathogens
w/circulatory – to transport materials to and from cells

38. Reproductive System Interactions
1. w/endocrine – controls production of sex cells
2. w/muscular – uterus contracts to give birth – controlled by hormones
