External intercostals CONTRACT and internal intercostals RELAX. This lifts the ribs/thoracic cavity DOWN and IN.
Select the correct answer which best describes the breathing mechanics during INSPIRATION.
Ribs move down and in, diaphragm relaxes and moves upwards, chest decreases, external intercostal muscles relax.
Ribs move down and in, diaphragm contracts and moves downwards, chest decreases, external intercostal muscles relax.
Ribs move up and out, diaphragm relaxes and moves upwards, chest increases, external intercostal muscles relax.
Ribs move up and out, diaphragm contracts and moves down/flattens, chest expands, external intercostal muscles contract.
Explain the process of gas exchange at the alveoli.
Concentration of oxygen in the alveoli is high. Concentration of oxygen in the blood is low. This creates a steeper diffusion gradient/ oxygen diffuses quicker. Oxygen moves from the alveoli into the blood.
Concentration of oxygen in the alveoli is low. Concentration of oxygen in the blood is high. This creates a steeper diffusion gradient/ oxygen diffuses quicker. Oxygen moves from the blood into the alveoli.
Concentration of oxygen in the alveoli is the same as the concentration of oxygen in the blood. This removes the diffusion gradient. Oxygen does not move anywhere.
