Question
Gases constantly move in and out of the blood into the lungs. Identify the gases that move in and out of the respiratory system.
Solution
The gases that move in and out of the respiratory system are primarily oxygen and carbon dioxide.
Step 1: Inhalation When you inhale, air enters your lungs. This air is rich in oxygen, which is needed by all the cells in your body to function properly.
Step 2: Gas Exchange in the Lungs Once the air is in your lungs, the oxygen in the air moves across the thin walls of the alveoli (tiny air sacs in the lungs) and into the bloodstream. This process is known as diffusion.
Step 3: Transportation of Oxygen The oxygen-rich blood is then transported by the circulatory system to all the cells in the body.
Step 4: Cellular Respiration Inside the cells, oxygen is used to produce energy in a process called cellular respiration. This process produces carbon dioxide as a waste product.
Step 5: Exhalation The carbon dioxide waste is transported back to the lungs via the bloodstream, where it moves across the alveoli and is exhaled from the body.
So, in summary, oxygen is inhaled into the respiratory system and carbon dioxide is exhaled out of it.
