  1. Organ Systems and Homeostasis The Human Body!

  2. Cells…Tissues…Organs…Systems • Cells: Basic unit of structure and function—keeps organisms alive • Tissues: Group of specialized cells that perform the same function—what are the 4 types?

  3. 4 Types of Tissue • Connective: Connects all parts of body • Epithelial: Surfaces of body inside and out • Muscle: Makes parts of the body move • Nervous: Controls messages between brain & parts of body

  4. TissuesOrgansOrgan Systems • What are organs? • ….made up of tissues that do a specific job!

  5. Organ Systems • What is an organ system? • Group of organs that work together to perform a major function • There are 11 in the human body • ISM are the first 3! • 1. Integumentary: (P511) skin, hair and nails • Function: provides a barrier and protection • 2. Skeletal: (P 519) bones, cartilage, ligaments, tendons • Function: Provides support and protection, minerals, blood cells • 3. Muscular: (P 527) muscles • Function: Pulls on the skeleton to provide movement

  6. What are these 3 organ systems?

  7. The next 6 organ systems • 4. Circulatory: (P 512): tube like vessels throughout body provides a transportation network • Function: carries food and oxygen to all the cells • 5. Respiratory (P 512): lungs, nose, pharynx, larynx, trachea, bronchi, bronchioles, lungs • Function: takes in oxygen and disposes of carbon dioxide • 6. Digestive System (P 512): mouth, pharynx, esophagus, stomach, small and large intestines, rectum, liver, pancreas • Function: breaks down food into small molecules the body can use

  8. 7. Excretory System: (P512): kidney, ureter, urinary bladder, urethra • Function: removes waste from the breakdown of materials in the bloodstream • 8. Immune System: (P568): specialized white blood cells • Function: destroys disease-causing bacteria and viruses • 9. Reproductive: male males-testes, epididymis, vas deferens, urethra, and penis; Females-Ovaries, Fallopian tubes uterus, vagina • Function: contains organs that produce sex cells and produce chemicals that regulate physical development of maturing bodies.

  9. C, R, D, E, I, R: These 6 carry out the processes of life.

  10. Last 2 are Nervous and Endocrine These two provide control over body processes.

  11. 10. Nervous: Brain, spinal cord, peripheral nerves, (senses: sight, hearing, touch, smell, taste) • Functions: Recognizes and coordinates the body’s responses to changes in its internal and external environments • 11. Endocrine: Glands- Hypothalamus, pituitary, pineal, thyroid, parathyroid, adrenals pancreas, ovaries (females), testes (males) • Function: Controls growth, development, and metabolism, maintains homeostasis

  12. I, S, M, C, R, D, E, I, R, N, E • I, S, M, C, R, D, E, I, R, N, E • ISM (I See My) • CRDEIR (Cat Running Delightfully Except In Rooms) • NE (Not Empty)

  13. Homeostasis • All of the body systems work together to maintain homeostasis! • The process by which an organism’s internal environment is kept stable in spite of changes in the external environment. • What are examples? • Why is this important?
