Gas Exchange
This gas you inhale is needed for cellular respiration.
What is oxygen?
When you get too hot, your body does this to cool down.
What is sweating?
This sugar is your body’s main energy source.
What is glucose?
Your body loses water through sweating and this other common action.
What is urination? (peeing)
This is the process of keeping the internal environment stable.
What is homeostasis?
This gas you exhale is a waste product.
When you get too cold, this body response helps warm you up.
What is shivering?
This hormone lowers blood sugar.
What is insulin?
This organ controls how much water you keep or get rid of.
What are the kidneys?
Homeostasis keeps this type of environment inside the body.
What is a stable/internal environment?
These tiny air sacs in the lungs are where gas exchange happens.
What are alveoli?
These open wider when you’re hot to release heat from your skin.
What are blood vessels dilating?
This hormone raises blood sugar when it drops too low.
What is glucagon?
The hormone that tells the kidneys to save more water.
What is ADH?
This word means any change that the body reacts to.
What is a stimulus?
The movement of gases from high concentration to low concentration.
What is diffusion?
These narrow to keep heat inside your body when you’re cold.
What is blood vessels constricting? (closing)
This organ releases both insulin and glucagon.
Drinking water increases this, raising your water balance.
What is hydration / water levels?
This kind of feedback loop counteracts (reverses) a change.
What is negative feedback?
What is the formula for cellular respiration?
What is oxygen + glucose = ATP + carbon dioxide + water vapor
The part of the body that controls the thermoregulation feedback loop.
What is the brain?
Eating food increases this level in your body.
What is blood glucose?
True or false, you can drink too much water.
What is true?
Sweating when you’re hot is an example of your body doing this.
What is responding to a stimulus / maintaining homeostasis?
