Homeostasis is maintained through feedback mechanisms.<br><br> a. True<br> b. False
Kaylis [27]

Answer:

a. True

Explanation:

An endocrine system refers to a series of ductless glands and organs responsible for the production and secretion of hormones that are used by the body for the performance of various functions such as metabolism, controlling growth, reproduction, mood, sleep, etc. These hormones are secreted directly into the circulatory system (blood) and then transported to the organs and tissues in the body.

Basically, the endocrine system contributes significantly to the state of homeostasis in the body.

Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment that is ideal to enhance life and proper functionality.

Homeostasis is maintained through feedback mechanisms, which are either positive or negative feedback.

During a negative feedback, a sensor and a control center in the body of a living organism maintains blood glucose to regulate blood pressure by releasing glucagon to increase blood sugar or releasing insulin to decrease blood sugar.

For a positive feedback, a sensor and a control center aids child birth by causing the uterine to contract.

The main problem that your central nervous system will try to solve is how to get out of this place.

<h3>B. What is the somatic nervous system probably doing?</h3>

It is releasing stimuli so that the pupil dilates and the blood goes to the muscles, to give greater physical vigor.

<h3>ç. Which part of the autonomic nervous system is likely to be active and what is it doing?</h3>

The autonomic nervous system is a part of the nervous system that functions independently of will and consists of neurons that conduct impulses from the central nervous system (brain and/or spinal cord) to the glands, smooth muscle and heart muscle.

<h3>What are the physiological responses of adrenaline binding in the sympathetic autonomic system?</h3>

Adrenaline increases the overall activity of the heart, increasing both the heart rate and the force of contraction. The heart has β1 receptors in both contractile and specialized myocardium. When turning on, a series of cardiac effects can happen.

With this information, we can conclude that the main problem that your central nervous system will try to solve is how to get out of this place.
