Summary Breathing and Exchange of Gases MCQ Test
How We Breathe:
- We breathe in air (inhale) and breathe out used air (exhale) using our lungs and airways.
- Special muscles (between our ribs and the diaphragm) help us breathe by changing the pressure in our chest.
What Happens When We Breathe:
- Oxygen from the air moves into our blood in tiny air sacs in our lungs called alveoli.
- At the same time, carbon dioxide from our blood moves into these air sacs to be breathed out.
- Our blood carries oxygen to all parts of our body and picks up carbon dioxide to bring back to the lungs.
How Gases Move:
- Oxygen and carbon dioxide move by diffusion, which means they naturally spread from areas of high concentration to low concentration.
How Blood Carries Gases:
- Oxygen is mostly carried by a protein in our blood called hemoglobin.
- Carbon dioxide is mostly carried as bicarbonate in our blood.
Breathing Control:
- Our brain controls our breathing rate based on how much oxygen and carbon dioxide is in our blood.
