Answer:
The process by which dissolved gases are exchanged between the blood and interstitial fluids is called internal respiration (d).
Step-by-step explanation:
Internal respiration refers to the exchange of gases (oxygen and carbon dioxide) between the bloodstream and the body's tissues. During internal respiration, oxygen diffuses from the blood into the interstitial fluid surrounding the cells, while carbon dioxide moves from the interstitial fluid into the blood. This exchange occurs through the walls of the capillaries.
It's important to note that there are other terms related to respiration mentioned in the options, so let's briefly define them for clarity:
(a) External respiration: This refers to the exchange of gases that occurs between the external environment and the lungs. It involves the inhalation of oxygen from the air and the exhalation of carbon dioxide.
(b) Breathing: This term refers to the process of inhaling and exhaling air, allowing for the exchange of gases in the lungs.
(c) Cellular respiration: This refers to the process by which cells generate energy from glucose and oxygen, producing carbon dioxide and water as waste products.
(e) Pulmonary ventilation: This term specifically refers to the movement of air in and out of the lungs during breathing.
In the context of the question, the specific process being asked about is the exchange of dissolved gases between the blood and interstitial fluids, which is internal respiration.
