Question

a student is building a model to illustrate how multicellular organisms can regulate their temperature through their skin. what could be included in the model to illustrate that temperature regulation involves more than one body system?

fingernails

blood vessel

teeth

Explanation:

Temperature regulation in multicellular organisms is a complex process. Skin (integumentary system) is involved in heat loss (e.g., sweating). Blood vessels (cardiovascular system) play a role - vasodilation (to release heat) and vasoconstriction (to conserve heat). Teeth are mainly for mechanical digestion and not directly related to temperature regulation.

Answer:

blood vessel
