Uvula
Part of the soft palate, prevents food and liquid from going up when you swallow
Which gas do we exhale more than we inhale?
Carbon dioxide
Aerobic respiration
Cells break down nutrients to produce ATP.
Tendons
Connect muscle to bone
areolar connective tissue
Found in cell tissue exposed to the outside of the body
Does a high fever have an effect on the body?
It can permanently denature enzymes and proteins.
