  1. Quiz Time! • Take out a pen/pencil. • Move everything else off your desk: water bottles, purses, papers, etc. • Make sure no notes or papers are visible on the floor. • You will have 20 minutes to complete the quiz. • There will be NO talking during the quiz, if you finish early, stay silent and feel free to draw a picture to entertain yourself.

  2. Catalyst #4What do we need to survive? • On a piece of paper, write down at least 3 things you think our human body needs to survive, and explain why we need them to survive. .

  3. Survival Needs • Nutrients • Oxygen • Water • Normal Body Temperature • Atmospheric pressure

  4. Mr. Ward’s Class: North Clayton High School Body/Organ Systems Overview

  5. Integumentary System • Forms the external bodycovering, protects deeper tissue from harm • Helps regulate body temperature • Has sensory receptors for touch, temperature, pain • Main organ is skin, also includes hair, nails, sweat and oil glands Figure 1.2a

  6. Integumentary System: when things go wrong • Example: Vitiligo • Vitiligo is a skin condition in which there is a loss of brown color (pigment) from areas of skin, resulting in irregular white patches that feel like normal skin.

  7. Skeletal System • Protects and supportsbody organs • Provides muscleattachment for movement • Site of blood cellproduction • Stores minerals • Fact:Each bone is an organ! • You have 206 bones! (adult) Figure 1.2b

  8. Skeletal System: when things go wrong • Arthritis:Arthritis is inflammation of one or more joints. A joint is the area where two bones meet. (Inflammation is the body’s response to injury/affliction in which it becomes reddened, swollen, hot, and often painful.) Severe Rheumatoid Arthritis

  9. Muscular System • Produces movement • Maintains posture • Produces heat • Each muscle is an organ • 700+ muscles! • Bro, Do you even lift bro? Figure 1.2c

  10. Muscular system: when things goes wrong: • Muscular dystrophy: a group of inherited disorders that involve muscle weakness and loss of muscle tissue, which get worse over time.

  11. Nervous System • Fast-acting controlsystem • Regulates body activity by responding to internal and external changes • Activates muscles andglands • Brain, spinal cord, nerves Figure 1.2d

  12. Nervous System: when things go wrong • Parkinson's disease is a disorder of the brain that leads to shaking (tremors) and difficulty with walking, movement, and coordination.

  13. Endocrine System • Slow- acting control system • Controls and coordinates the body through hormones that affect: • Growth • Reproduction • Metabolism • Many different organs/glands Figure 1.2e

  14. Endocrine System: when things go wrong • Diabetes: a condition in which the pancreas does not produce enough of the hormone insulin or the body does not effectively use the insulin it does produce. 

  15. Cardiovascular System • Transports materials in bodyvia blood pumped by heart • Oxygen • Carbon dioxide • Nutrients • Wastes Figure 1.2f

  16. Cardiovascular System:when things go wrong • Aheart attack occurs when blood flow to a part of your heart is blocked for a long enough time that part of the heart muscle is damaged or dies. 

  17. Lymphatic System • Returns fluids to blood vessels • Cleanses the blood • Involved in immunity Figure 1.2g

  18. Lymphatic/Immune System:when things go wrong • Elephantiasis: a disease that is characterized by the thickening of the skin and underlying tissues, especially in the legs and male genitals. In some cases the disease can cause certain body parts, such as the scrotum, to swell to the size of a basketball. Caused by wormlike creatures invading the lymphatic system.

  19. Respiratory System • Keeps blood supplied with oxygen • Takes in oxygen and releases carbon dioxide Figure 1.2h

  20. Respiratory system:when things go wrong • Asthma is a disorder that causes the airways of the lungs to swell and narrow, leading to wheezing, shortness of breath, chest tightness, and coughing. 

  21. Digestive System • Breaks down food • Allows for nutrient absorption into blood • Eliminates indigestible material Figure 1.2i

  22. Digestive system: when things go wrong • Gastroesophageal reflux disease (GERD) is a condition in which the stomach contents (food or liquid) leak backwards from the stomach into the esophagus (the tube from the mouth to the stomach).

  23. Urinary System • Eliminates nitrogenous wastes • Maintains acid-base balance • Regulates water and electrolytes Figure 1.2j

  24. Urinary system: when things go wrong • A kidney stoneis a solid concretion crystal aggregation formed in the kidneys from dietary minerals in the urine.

  25. Reproductive System • Produces offspring • Continuation of species Figure 1.2k–l

  26. Reproductive system:when things go wrong • Sexually transmitted diseases: HPV (genital warts) Genital warts are soft growths on the skin and mucus membranes of the genitals. They may be found on the penis, vulva, urethra, vagina, cervix, and around and in the anus.

  27. Interrelationships Among Body Systems Figure 1.3

  28. Practice! (don’t look at your notes) • 1. ______________ system transports materials in body via blood pumped by heart. • 2. ______________ system allows for nutrient absorption into blood. • 3._____________ system: • Protects deeper tissue frominjury • Helps regulate body temperature • Place of Vitamin D production • 4. __________ system is the quickly acting controlcenter that regulates body activity by responding to internal and external changes.

  29. Body Systems Break Up Letter Assignment • This assignment will be completed in pairs. (only two people, no groups of 3+) • You may select your partner for this activity. • The objective of this assignment is to solidfy your knowledge of the 11 body systems. • You are going to write a 1 page letter explaining why you are breaking up with your significant other. Your significant other is your partner, who is also a body system. • For instance, I am skeletal system, and I am breaking up with my significant other, digestive system. • You will have to include at least 10 facts about your and your significant other’s body systems. • Examples of good sentences: • “Digestive system…I can’t be with you anymore..all you do is eat and stuff your fat esophagus with proteins and fats…can’t you do anything besides process food into nutrients? Maybe take me on a date every once and a while!”
