15

Function of endocrine system 

Produce hormones that regulate metabolism, growth, and development. 

16

Function of integumentary system 

Act as a barrier to protect the body from the outside world, protect against diseass, retain body fluids, eliminate waste products, regulate body temperature, and vitamin D synthesis. 

17

Function of respiratory system 

Taking in oxygen and expelling carbon dioxoide. 

18

Function of nervous system 

Control of the body and communication among the body parts. 

19

Function of the excretory (urinary) system 

  • To remove waste from the blood in the form of urine
  • Keep a salt balance in the blood 

20

Function of the reproductive system

  1. Female
    1. Produce egg cells
    2. Protect and nourish the offspring until birth
  2. Male
    1. Produce and deposit sperm 

21

Function of lymphatic system 

  • Removal of interstitial fluid from tissues
  • Transports fatty acids from the digestive system
  • Transports white blood cells to and from the lymph nodes into the bones 

22

Function of the digestive system 

Converting food into nutrients for the body 

23

Function of circulatory system 

  • Delivery of oxygen, nutrient molecules, and hormones in the body
  • Removal of carbon dioxide, ammonia, and other metabolic wastes
  • *Capillaries are the points of exchange between the blood and surrounding tissues 

24

Function of the muscular system 

  • Movement
  • Maintenance of posture and body position

25

Function of skeletal system 

  • Support 
  • Movement
  • Protection
  • Blood cell formation
  • Calcium storage
  • Endocrine regulation 

26

Function of immune system 

  • Protect the body from organisms and substances that invade the body and cause disease 

27

What are the components of a homeostatic mechanism? 

Feedback loop

  1. Receptor
    1. Is a structure that senses a change in the body 
    2. Detects the change 
  2. Controller
    1. Integrating center
    2. A mechanism that processes information, relates it to other infomration, and "makes a decision" about the appropriate response
    3. Decides, interprets, commands 
  3. Effector 
    1. ​Is the cell or organ that carries out the final corrective action
    2. Responds and carries out

28

Purpose of the negative feedback loop

To return back to the original state

29

Purpose of the postive feedback loop

To move away from the original state

30

Example of negative feedback loop

  • Body temperature drops so the muscles start to shiver to increase body temperature
  • Body temperature increases so the skin produces sweat to cool down the body 

31

Example of positive feedback loop

  • Labor; the baby pushes on the uterus so the uterus contracts which causes the baby to push on the uterus more and more, until the baby cames out
