    Gastrointestinal System
    If blood glucose is high, what does the liver do about it?
    This process removes glucose from circulation. Choices B and C would increase blood glucose. Transamination is done to amino acids to produce different amino acids.

    Body Temperature, Energy and Heat Loss
    Evaporation of sweat cools our body because the evaporating water molecules:
    The water molecules in sweat that have the highest kinetic energy are the ones that evaporate first. This leaves the slower moving molecules behind, and they have a lower temperature. These slower molecules will gain energy from the body heat and eventually have enough kinetic energy to evaporate, again cooling the body as more kinetic energy is transferred away from the body.

    What are the primary types of body tissue?
    These are the four primary types. Blood is not a “type” of tissue.
