Current Question (ID: 14382)

Question:

Respiration is under neural and chemical regulation. The receptors for chemical regulation are located in the:

Options:

1. walls of the carotid and aortic arteries and in the medulla oblongata.
2. walls of the carotid and aortic arteries only.
3. medulla oblongata and in the walls of the superior and inferior vena cavas.
4. walls of the carotid and aortic arteries and in the walls of the superior and inferior vena cavas.

Solution:

The receptors for chemical regulation of respiration are located in the walls of the carotid and aortic arteries, and in the medulla oblongata. These receptors are called chemoreceptors and are sensitive to changes in the partial pressures of oxygen, carbon dioxide, and hydrogen ions in the blood. The chemoreceptors in the walls of the carotid and aortic arteries are known as peripheral chemoreceptors, while those in the medulla oblongata are known as central chemoreceptors. These chemoreceptors send signals to the respiratory centers in the brainstem to adjust the rate and depth of breathing in response to changes in blood gas levels.
