Homeostasis (Amoeba Sisters Vid)

A state of balance (blood within accurate PH, good blood glucose, temperature)

**Ectotherm** is cold blooded, fluctuating body temperature with environment

Warm blooded is **endotherm**, using homeostasis and negative feedback to regulate body temperature

Vasodilation is done to cool the body

Vasocontraction is done to conserve body heat, keep you warn

Negative feedback is when a variable triggers a response to return to a balance, sometimes creating a negative feedback loop

Negative feedback is done with blood sugar and temperature regulation

Negative feedback with blood sugar: when glucose is too high, insulin is released; if too low, glucagon is released to release more glucose

Positive feedback intensifies the variable instead of counteracting it

With birth, the cervix is pressured, and the hormones involved with it causes contractions; more hormones release more contractions, making a positive feedback loop to birth the baby

With type 1 diabetes, the pancreas does not properly make insulin, not being able to create glucose and derailing the cellular respiration process (negative feedback didn’t work)
