Jasmine is a healthy girl who is playing outside. Her internal body temperature rises to 38 degrees Celsius, which is above normal. How does her body most likely respond to help her return to homeostasis?

See the answer below

Explanation:

Jasmine's body would help her return to homeostasis by using the negative feedback loop.

The negative feedback loop works to negate the process or processes that lead to the body's setpoint being breached. The setpoint refers to the normal range of operation of body processes such as temperature, pressure, etc.

The skin of Jasmine acts as a sensor and sends information to the control center, the brain. The brain reads the temperature data, finds out that the setpoint has been exceeded, and sends information to the effectors to initiate processes that will return Jasmine's body temperature to normal.

One of the effectors, the blood vessels that supply blood to the skin becomes dilated. Consequently, more blood is supplied to the skin and more heat is lost from the skin due to radiation - blood being a conductor of heat in the body. Another effector, the sweat glands, release sweat to the skin. The evaporation of sweat from the surface of the skin causes the body to cool down. These processes work synergistically to return the body temperature of Jasmine back to homeostasis.
