Summary Introduction

To review:

The reason why the negative feedback loop is unable to prevent muscle contractions and pain during labor in a pregnant woman.

Introduction:

A pregnant woman may enter labor in the last week of gestation, which leads to the birth of the child. A series of events occur during the labor, which includes intense muscle contractions. These muscle contractions force the fetus from the uterus to the outside through the birth canal. The muscle contractions are extremely intense and painful.

Multiple answers: Choose all of the relevant answers from the choices below. answer choices a)Intracellular fluid b)Intersitial fluid c)Extracellular fluid d)External environment (e.g., mother's nipple) e)Blood plasma   2)Which of the following is NOT true regarding negative feedback loops and homeostasis? answer choices a. Homeostatic control systems cannot maintain complete constancy of the internal environment b. The set point of some variable can be reset c. It is always possible for physiological variables to be maintained in a relatively constant manner using homeostatic control systems d. The stability of an internal environment variable is achieved by balancing inputs and outputs e. In negative feedback systems, a change in the variable being regulated brings about responses that tend to move the variable in a direction that is opposite to the…
