2. 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.

3. The Human Body Levels of Organization

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

6. Anatomical positions • Dorsal • Ventral • Caudal/Posterior • Cranial/Anterior • Lateral • Medial

7. 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? HORMONES

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

9. 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.

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

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

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

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

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

17. 3rd Layer  Hypodermis or Subcutaneous • Contains layer of fat and • connective tissue; • provides insulation

18. Fat Epidermis Dermis Subcutaneous

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

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

21. Degrees of burns Third Degree Burn-The entire epidermis is charred or burned away,andthe burn may extend into the dermis. Often such a burn is not painful at first because the sensoryreceptorsin the dermis may have been destroyed.

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

23. 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 rejectionof the • tissue unlikely.

24. Quick Question? If you are sweating on a hot day, which system is your body using to cool itself off?

27. Muscular System

28. 3 types of muscle tissue Skeletal muscle Smooth muscle Cardiac muscle Muscular System

29. 3 Types of Muscles Types of Muscle Voluntary Involuntary Skeletal Cardiac Smooth Responsible for movement Responsible for pumping blood Responsible for constricting blood vessels, GI tract, & other areas of body

30. 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.

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

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