The alveoli.
Chat with our AI personalities
The alveoli is the division of the respiratory system where gas exchange with the blood occurs. Oxygen from the inhaled air diffuses into the blood in the capillaries surrounding the alveoli, while carbon dioxide diffuses from the blood into the alveoli to be exhaled.
The respiratory system exchanges gases between air and blood. This process occurs in the lungs, where oxygen is taken in from the air and carbon dioxide is released from the blood into the air.
The alveoli are the structures in the respiratory system responsible for the exchange of oxygen and carbon dioxide. They are located in the lungs and have a thin membrane that allows for gases to be exchanged with the blood vessels.
The respiratory system is responsible for providing gas exchange between the blood and the air. This process occurs in the lungs where oxygen is taken up by the blood and carbon dioxide is released from the blood into the air through the alveoli.
The respiratory system oxygenates the blood (providing oxygen to tissues of the NS), allowing for cellular metabolism. It also eliminates carbon dioxide from the blood as a waste product of cellular metabolism of the NS.
Inhaling and exhaling.Breathing in and out. ************************************ To oxygenate blood (hemoglobin) and to remove carbon dioxide from blood (hemoglobin). But actually the respiratory system has many functions: 1. Exchanges gases (as stated above) 2. Homeostatic regulation of the body's pH through the regulation of CO2 3. Protection from inhaled patholgens and irritating substances 4. Vocalization.
