What organ system helps regulate body temperature? Skeletal system Digestive system Integumentary system (skin) Respiratory system

## Step 1<br />The question asks which organ system helps regulate body temperature. The options provided are the skeletal system, digestive system, integumentary system (skin), and respiratory system.<br /><br />## Step 2<br />The skeletal system provides structure and support to the body, but it does not play a direct role in temperature regulation.<br /><br />## Step 3<br />The digestive system is responsible for breaking down food and absorbing nutrients, but it does not directly regulate body temperature.<br /><br />## Step 4<br />The respiratory system is involved in gas exchange and does not directly regulate body temperature.<br /><br />## Step 5<br />The integumentary system, which includes the skin, is the organ system that helps regulate body temperature. The skin acts as a barrier to protect the body from the outside world and also plays a crucial role in temperature regulation. It does this through various mechanisms such as sweating, which cools the body as the sweat evaporates, and the dilation or constriction of blood vessels in the skin, which can either increase or decrease blood flow to the skin and thus regulate heat loss or retention.
