How many bones are in an adult’s human body?
Approximately how many muscles do humans have?
206 bones
650 muscles

2. Learning Target
Today I am learning about the body systems because they keep me alive by working together.

3. We will come back to this after the lesson to review your thoughts…
Question to Ponder…
What is a system? (in general…not specifically body systems)
We will come back to this after the lesson to review your thoughts…

4. Human Body Systems Review
Structures, Functions, and Interactions

5. Skeletal
Structures: bones, cartilage, joints, marrow Functions: provides shape and support, enables you to move, protects your internal organs Interactions: * bones make your red blood cells (cardiovascular/circulatory) * helps you move (muscular)

6. Skeletal

8. Muscular
Structures: skeletal muscle, smooth muscle, and cardiac muscle Functions: Involuntary muscles for breathing and digesting food; Voluntary muscles are under your control (movement) Interactions: All systems b/c all of your organs are made of muscle

9. Muscular

10. Ted Ed Video: How do muscles grow?

11. Nervous
Structures: brain, spinal column, nerves. Functions: sends electrical messages to detect & interpret info from inside and outside the body; control center Interactions: Tells muscles to contract (voluntary), tells heart to pump (involuntary)

12. Nervous

13. Ted Ed Video- How does the brain respond to pain?

14. Endocrine
Organs: glands such as hypothalamus, thyroid, ovaries, testes Functions: Controls body functions by using chemical messages from glands Interactions: Sends growth hormones to skeletal system, releases adrenaline into the blood stream to stimulate the muscles into action.

15. Endocrine

16. Brain Pop- Endocrine System

17. Digestive
Structures: Mouth, esophagus, liver, stomach, gallbladder, pancreas, large intestines, small intestines, rectum Function: breaks down food into molecules the body can use, and eliminates waste Interactions: Uses the circulatory system to take food to the individual cells, forms the end of the excretory system to expel solid waste.

20. Question to Ponder…
What is a system?
a set of connected things or parts forming a complex whole, in particular.
How does this definition relate to our body systems?

21. Mind Stretcher 1/25/17
Match the system to its function: Digestive, Endocrine, Nervous, Muscular, Skeletal
System
Function:
Glands to secrete hormones/adrenaline, etc.
Enable movement
Give shape and support; protect inner organs
Break down food for nutrients
Send electrical messages; Control center
Endocrine
Muscular
Skeletal
Digestive
Nervous

22. Lymphatic System
Organs: Tonsil, Spleen, Thymus, Lymph Nodes Function: returns leaked fluids to blood vessels and helps get rid of bacteria and viruses. Interactions: White blood cells made in the bones grow into T cells in the thymus.

25. Integumentary System
Organs: Skin, Hair, Nails Functions: Protects; keeps water in & foreign particles out; allows you touch; regulates temperature; gets rid of wastes Interactions: Works with the nervous system to keep you aware of your surroundings.

26. Integumentary System

28. Digestive System (Lower part)
Structures: Large Intestines, rectum, anus Functions: Material that cannot be absorbed into the blood stream is compacted in the large intestines for elimination. Interactions: The large intestine absorbs water into the cardiovascular system for use throughout the body.

31. Urinary
Structures: kidney, urinary bladder, urethra Functions: Blood is filtered through the kidneys to remove cell/body waste. LIQUID waste is stored in the bladder and eliminated as urine. Interactions: Cleans/filters waste from the circulatory system.

32. Urinary

34. Ted Ed Video-What do kidneys do?

35. Respiratory
Structures: Nose, Trachea (Wind Pipe), Lungs: Bronchi/Bronchioles, Alveoli Function: Moves oxygen into the body and removes carbon dioxide and water vapor from the body. Interactions: Circulatory system carries oxygen to the cells and carbon dioxide away.

36. Respiratory

37. Ted Ed Video- What do the lungs do? https://youtu.be/8NUxvJS-_0k

38. Reproductive
Structures: Testes, ovaries, and uterus Function: Create a new living individual Interactions: The endocrine system regulates the hormones necessary for sexual maturity and reproduction.

39. Circulatory or Cardiovascular
Structures: Heart, blood vessels Functions: Heart pumps blood through all blood vessels. Interactions: Highway system of the body, carries food (digestive) and oxygen (respiratory) to the cells and carries waste away.

40. Cardiovascular
