ANATOMY QUESTION
THANK YOU!

True/False: Mark the following statements as true (T) or false (F). If the statement is false, correct it to make it a true statement. a. Hyperventilation causes a retention of carbon dioxide and an increase in the hydrogen ion concentration of the blood. b. When the pH of the blood falls (Gie., the blood becomes more acidic), a negative feedback loop is triggered that increases the rate and depth of ventilation to remove carbon dioxide from the blood. The two main muscles of inspiration are the diaphragm muscle and internal intercostal muscles. The muscles of inspiration increase the pressure inside of the lungs above atmospheric pressure in order c. d. to cause inspiration.

Explanation / Answer

A. False.

Hyperventilation causes release of more carbon dioxide from the body. This results in fall in hydrogen in concentration in blood leading to rise in blood pH causing respiratory alkalosis.

B. True.

C. False.

Two main inspiratory muscles are diaphragm muscles and external intercostal muscles.

D. False.

Muscles of inspiration causes increase in the thoracic cavity which in turn causes increase in the volume of lungs inside. Increase in volume in turn decreases the pressure within the lungs and thus air form outside rushes into the lungs.
