1. what are the five functions of the integumentary system? insert text here 2. what is our largest organ? insert text here 3. what do you think would happen if we didnt have subcutaneous fat? insert text here

Explanation:

1. The five functions of the integumentary system are protection (from pathogens, physical damage), temperature regulation (sweating and blood - vessel constriction/dilation), sensory reception (nerve endings detect touch, pain etc.), vitamin D synthesis (when exposed to sunlight), and excretion (removal of small amounts of waste through sweat).
2. The skin is our largest organ. It covers the entire body and has multiple layers and functions.
3. Without subcutaneous fat, we would have less insulation, making it harder to maintain body temperature. There would also be less cushioning for internal organs, increasing the risk of injury from physical impacts, and our skin may appear more wrinkled or loose as it lacks the support provided by the fat layer.

Answer:

1. Protection, temperature regulation, sensory reception, vitamin D synthesis, excretion.
2. Skin.
3. Less insulation, less organ - cushioning, and looser skin appearance.
