Temperature-sensitive nerve cells monitor the body temperature and provide information about its status to a temperature-control center in the hypothalamus, a part of the brain.The hypothalamus can bring about adjustments in body temperature by inducing shivering or sweating, among other things.Indicate the roles served by each component of this control system using the following answer code. a.controlled variable b.integrator c.sensor d.effector -Temperature-sensitive nerve cells

A(n) ____________________ is a collection of organs that perform related functions and interact to accomplish a common activity that is essential for survival of the whole body.

Explain the long-term adaptations made by the heart in response to an exercise regimen of sufficient intensity and duration, and explain how this is beneficial to the heart and to the athlete.

Some activities performed by the muscular and nervous systems are not directed toward maintaining homeostasis.

All cells that are not pluripotent can reproduce.

Insulin is a hormone that is secreted into the lumen of the intestine in response to the presence of food.

The endocrine system relies on the circulatory system for the transport of hormones.

A mechanistic explanation of why a person breathes is to obtain oxygen.

Exocrine glands are the only structures in the body capable of secretion.

Food in your stomach is in direct contact with ______ tissue.
