The response of the body's homeostatic control systems to large increases in muscle O₂ requirements during heavy exercise is the increase in body's pulmonary ventilation.
Homeostasis is the state of balanced internal system of the body. A homeostatic body does gets affected by the outer environment as it adjusts itself accordingly. The state of homeostasis can be in terms of thermoregulation, blood glucose regulation, osmoregulation, etc.
Pulmonary ventilation is the process of inhalation and exhalation of air. This is done to fulfil the demand of oxygen in the body and also to remove the waste carbon dioxide from the body. Pulmonary ventilation in simple terms is breathing.

Answer:
<u>d. Skeletal muscle</u>
Explanation:
There are two components of efferent nervous system.
- <u>Somatic nervous system</u>
- <u>Autonomic nervous system</u>
<u>SOMATIC NERVOUS SYSTEM:</u>
Somatic nervous is one of the components of efferent/motor nervous system.
It controls <u>voluntary activities</u>. It involves the <u>control of skeletal muscles</u>.
It is composed of <u>the motor neuron and the innervating muscle</u>.
<u>AUTONOMIC NERVOUS SYSTEM:</u>
Autonomic nervous system is the other efferent/motor system of the body. It controls the <u>involuntary activities</u>. It involves the control of <u>cardiac muscle, glands and smooth muscles</u> of the body.
It is composed of<u> 2 neurons; preganglionic and postganglionic neurons.</u>
Autonomic nervous system is further divided into:
- Sympathetic nervous system (it is responsible for flight and fight responses)
- Parasympathetic Nervous system (it is responsible for rest and digestion)
- Enteric division ( controls Gastrointestinal system)
<u>QUESTION:</u>
<u>d. skeletal muscle</u>
This is the correct answer choice as skeletal muscles are not controlled by autonomic nervous system. They are controlled by somatic nervous system and are under voluntary control.
This depends on the secretion of <em><u>antidiuretic hormone </u></em><em><u /></em><u /> ADH ...
If there is large amount of water present in your body then ADH production decreases and rate of urination increases so that extra water can be removed...
if you are dehydrated then ADH secretion increases so that you can preserve more water in your body hence amount of urine decreases....
