What is homeostasis? If your body is in homeostasis, everything in your body is balanced, and internal conditions remain stable and relatively constant.

What is homeostasis? If your body is in homeostasis, everything in your body is balanced, and internal conditions remain stable and relatively constant. Our bodies do many things to keep us in homeostasis

One way an organism maintains homeostasis is by responding to its environment.

Homeostasis Mammals are warm blooded, which means we need to maintain a fairly constant internal temperature. Humans need to stay around… 98.6o F

Homeostasis is maintained by Feedback Mechanisms Think of your thermostat at home: when the temperature drops, the heater turns on. When the temperature gets too hot, the A/C turns on.

Homeostasis The kidneys are used to remove excess water and ions from the blood. These are then expelled as urine. The kidneys perform a vital role in homeostatic regulation in mammals, removing excess water, salt, and urea from the blood.

Homeostasis Sleeping is also a function to keep your body in homeostasis. Your body needs sleep and will make you sleep if you are sleep-deprived.

Homeostasis When bacteria or viruses that can make you ill get into your body, your immune system kicks in to help maintain homeostasis. It works to fight the infection before it has the opportunity to make you sick, ensuring that you remain healthy.

Homeostasis Your body regulates blood sugar throughout the day using glucagon and insulin

Homeostasis keeps us in Balance
