Answer:

Keeping the alveoli open and for constant gas exchange.

Explanation:

After maximum expiration of the air in the lungs, there remains still some air called the residual volume. This is because the alveoli, the smallest sacs in the lungs which take part in the exchange of gases between the lungs and the bloodstream, need to stay inflated and open. This also ensures that the gas exchange is continuous between breaths which is really important. I hope this answer helps.

Provide brief overview of the nervous system and its role in the maintenance of homeostasis.
Alona [7]
Explanation:

The nervous system has two major anatomical subdivisions:

Central Nervous System: Composed of the brain (inside the skull) and the spinal cord (inside the spinal column).

The brain and spinal cord are responsible for processing and integrating the various sources of information to allow us to develop a response. Therefore, the main function of the somatic nervous system is to connect the Central Nervous System with the organs and skeletal muscle to carry out our daily functions.

Peripheral nervous system: it is everything that is outside the bone cavity and is formed by the nerves and nerve ganglia that extend outside the central nervous system.

The peripheral nervous system has a somatic component, which is associated with the voluntary control of body movements through the use of skeletal muscles. This means that it is responsible for all the functions that we are aware of, including the movement of our arms, legs, and other parts of our body.

On the other hand, the autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiological processes. These processes include heart rate, blood pressure, breathing, digestion, and sexual arousal. The autonomic nervous system contains three divisions: sympathetic, parasympathetic, and enteric.

Due to the above relationships and anatomical subdivisions we can say that the nervous system is responsible for regulating and maintaining homeostasis. In fact, through its receptors, neurotransmitters, nervous inputs, and outputs, the nervous system keeps us in touch with our environment, both external and internal.

We can conclude that the correct answer is:
