What is the bladder?
Use their muscles to take air in through holes in the sides of their bodies into tracheas which extend throughout their bodies and deliver oxygen to cells.
What are grasshoppers?

What are endotherms?
Removes waste products from the blood and turns them into urine
The biological process that allows humans and other organisms to maintain a steady body temperature
What is thermoregulation?
Large thin ears on elephants is an example of what kind of thermoregulation (evaporation, insulation, or surface area)

What are dialysis or kidney transplant?
Describe an example of structural thermoregulation in humans.
Example answers:
1. Sweat evaporates off skin and cools you down.
2. Blood vessels widening or constricting in to lose or keep heat.
3. Rapidly contracting muscles in shivering to warm up.
