The lungs, nose, and trachea are organs of the respiratory system. which best describes these organs?



after the body has begun shivering, what explains why it would stop shivering?



which is an example of how the body maintains homeostasis?

1. Answer;

They deliver oxygen to the blood.  

Explanation;

Different organs of the respiratory system includes; nose, pharynx, epiglottis, larynx, trachea, bronchi and lungs.

The major role of the respiratory system is to allow gas exchange (oxygen and carbon dioxide) with various parts of the body. The main objective and aim of the respiratory system organs is to enhance delivery of oxygen to the blood which would then be transported to all body parts.

2. Answer;

For the regular body activities to be carried out.

Explanation;

-When the temperature of the body drops below normal, shivering reflex is triggered to maintain homeostasis. It is therefore a bodily function in response to cold, mostly in warm blooded animals.

-Rapid muscle contraction and relaxation during cold weather causes Chills or what we call shivering. Shivering is the body's way of producing heat when it feels cold. Chills often predict the coming of a fever or an increase in the body's core temperature.

3. Answer;

Acid-base balance or body temperature control

Explanation;

-Homeostasis is the maintenance of the internal environment constant. In other words it is the ability of an organism to maintain stability in spite of changes in the environment. The human body is full of examples of homeostasis.

-Homeostasis serves to keep the body environment under control and keep the internal conditions right to enhance cellular functions and living. Lack of the right body conditions, certain processes such as osmosis, and proteins mainly enzymes, will not function properly.

-Examples of homeostasis includes; Acid-base balance, body temperature control and regulation of blood glucose among others.
