  1. INTRODUCTION TO HUMAN BIOLOGYpp. 907-910

  2. cells  tissues organs  organ systems

  3. BODY TISSUES

  4. muscle: contract in coordination upon stimulation (skeletal, cardiac, smooth) • nervous: receive and transmit information and signals (made of cells called neurons) • epithelial: line surfaces of bodies, cavities, canals • connective 1. bone, cartilage, tendons, blood 2. cells surrounded by extra-cellular, non- living tissue

  5. ORGANS • tissues working together

  6. ORGAN SYSTEMS • Skeletal: protection and support • Muscular: support and movement

  7. Circulatory: transport of gases, nutrients, waste, and chemicals to all parts of the body. • Respiratory: gas exchange

  8. Integumentary (skin): protection • Immune: fights pathogens

  9. Nervous: regulation, conduction, and coordination • Endocrine: controls body function via chemical messengers.

  10. Digestive: breakdown and absorption of food • Excretory: removal of liquid and solid wastes

  11. Reproductive: production of sex cells (offspring)

  12. BODY CAVITIES • spinal, cranial, thoracic, diaphragm, abdominal, pelvic

  13. Feedback Loops • Positive (Rarer) • The response of the system creates more of the same response • Run on the Bank, Allergic Reaction, Awful sound from a speaker • There is a rumor that a bank is going out of business. People get scared and start going to the bank to take out their money. People see that the bank is getting weak because of all the people taking out their money so they go to take their money. This happens more and more until the bank has no more money and goes out of business.

  14. Negative Feed back • The response of the system causes the action to stop • Thermostat, Insulin • When you set your thermostat to heat it turns the heat on and then the room heats up. When the room reaches a certain temperature, the thermostat reacts and turns off the heater. The room then cools down and the cycle reapeats.

  15. Homework • Read p 907 -910 • Problems p 910 #1-6 • Body Tissues Worksheets
