homeostasis/feedback loops

• Moving away from a target set point through amplification.
• sensor needs greater stimulus

through homeostasis (the usage of positive and negative feedback loops)

• trying to stabalize toward a certain target set point going possibly above and below the target until it is reached
• stimulus, sensor, control center, effector, stimulus

• temp regulation, glucose levels, etc.
• temp reg- glands open and sweat evaporates to take heat away to make temp drop but if it drops too far glands close and goosebumps pulls skin in.

• in childbirth, a baby's head pushing on a mothers cervix causes contractions which pushes more pressure on the cervix causes more contractions and so on.
• or fruit ripening which releases a gas that causes other apples to ripen and then those apples release a gas to make more apples ripe and so on

sensor- detect changes in the body and sends signals to the control center (usually the brain)

signal traveling to the control center

receives signal and initiates adjustments

command from the control center

organ or system that receives or executes a command

Blood pressure needs 120/80- circulatory, muscular, endocrine, and urinary systems work together to maintain a normal level
