3. Did you know?? 1. The adult body is made up of: 100 trillion cells, 206 bones, 600 muscles, and 22 internal organs. 2. Every square inch of the human body has about 19 million skin cells. 3. The average human head has about 100,000 hairs. 4. The circulatory system of arteries, veins, and capillaries is about 60,000 miles long. 5. The heart beats more than 2.5 billion times in an average lifetime. 6. There are about 9,000 taste buds on the surface of the tongue, in the throat, and on the roof of the mouth. 7. The strongest muscle in the body is the tongue. 8. The largest organ in the body is the skin. 9. The human heart creates enough pressure when it pumps out to the body, it can squirt blood 30 feet. 10. When you sneeze, all bodily functions stop... Even your heart. 11. You blink over 10,000,000 times a year. 12. It takes about 20 seconds for a red blood cell to circle the whole body. 13. Only 7% of the population are left handed. 14. There are 28 bones in your foot alone. 15. The average person falls asleep in seven minutes. 16. Children tend to grow faster in the spring.

4. Levels of Organization

5. Organ Systems Integumentary Muscular Skeletal Digestive Excretory Circulatory Respiratory Nervous Reproductive Immune Endocrine

7. Anatomical positions –Dorsal –Ventral –Caudal/Posterior –Cranial/Anterior –Lateral –Medial

9. ENDOCRINE SYSTEM The endocrine system controls your mood, sleep, hunger, digestion, emotions, breathing rate and the rate our heart beats just to name a few. So how could one system have so much influence?

10. ENDOCRINE SYSTEM Glands are the major organs of the Endocrine system. –Hypothalamus –Thyroid –Pancreas –ovaries/testies –Pituitary gland –Parathyroid –Thymus –Adrenal Glands

11. ENDOCRINE SYSTEM The functions of the Endocrine system are regulating your mood, growth and development, tissue function, and metabolism, as well as sexual function and reproductive processes.

13. Integumentary System $5 Integument…..aka….”Cover”

14. The integumentary system is composed of the 1.skin 2.nails 3. glands Function of skin: 1. Provide protection 2. Regulate body temperature 3. Sensory Integumentary System

16. Skin has 3 layers: 1.Epidermis – nails and hair 2.Dermis – blood vessels, nerves, glands, smooth muscle, and hair 3.Hypodermis – fat

17. Epidermis 1 st Layer  Epidermis Contains KERATIN – protein that forms hair, nails, calluses Contains MELANIN – gives skin color

18. DERMIS 2 ND Layer  Dermis Contains blood vessels, nerves, glands, smooth muscle, and hair Contains 2 types of glands: 1. Sweat – produces sweat 2. Sebaceous – produces oil

19. Hypodermis or Subcutaneous Contains layer of fat and connective tissue; provides insulation 3 rd Layer 

20. Epidermis Dermis Subcutaneous Fat

21. Degrees of burns First Degree Burn – Only the superficial epidermis is burned and is painful, but is not blistered.

22. Second Degree Burn - Deeper layers of epidermis are effected, could have inflammation, blisters, and the burned skin is often painful. Degrees of burns Caused by hot glue

23. Third Degree Burn- The entire epidermis is charred or burned away,and the burn may extend into the dermis. Often such a burn is not painful at first because the sensory receptors in the dermis may have been destroyed.  Degrees of burns

24. Extensive third degree burn- Potentially life threatening because of loss of skin, without this natural barrier, skin is exposed to the environment and is susceptible to infection and dehydration. Degrees of burns

25. Skin Graft - A skin graft is a surgical procedure in which a piece of skin is transplanted from one area to another. Often skin will be taken from unaffected areas on the injured person and used to cover a defect, often a burn. Taking the graft from the injured person makes rejection of the tissue unlikely.

30. Muscular System

31. 3 types of muscle tissue –Skeletal muscle –Smooth muscle –Cardiac muscle Muscular System

32. 3 Types of Muscles Types of Muscle CardiacSmooth Involuntary Skeletal Voluntary Responsible for movement Responsible for pumping blood Responsible for constricting blood vessels, GI tract, & other areas of body

33. Types of Muscle The most common job of the smooth muscle is to squeeze. Smooth muscle is involuntary, contains a single nucleus, and lacks striations.

35. Types of Muscle Pumps our blood Involuntary Contains striations and a single nucleus per cell.

37. Types of Muscle Attached to and moves your bones. Main job is for movement. Voluntary, multi-nucleate, & striated

39. Smooth, Cardiac, Skeletal??

42. Muscle fibers, myofibrils, filaments

44. Muscles work in pairs Muscles contract

46. Skeletal System

62. Types of Joints Joints are found where two or more bones come together. 1. Ball and Socket – shoulder and hip 2. Hinge – elbow and knee 3. Gliding – wrist and ankle 4. Pivot – head atop the vertebrae
