Answer 1

Answer:

1. Liver. The liver has many functions, but its main job within the digestive system is to process the nutrients absorbed from the small intestine. Bile from the liver secreted into the small intestine also plays an important role in digesting fat and some vitamins
2. During the process of inhalation, the lung volume expands as a result of the contraction of the diaphragm and intercostal muscles (the muscles that are connected to the rib cage), thus expanding the thoracic cavity. Due to this increase in volume, the pressure is decreased, based on the principles of Boyle's Law.
3. Notice that the airways are narrowed (skinny), so less air can move in and out of the lungs. When things are working normally, the amount of air we breathe in is about the same as the amount of air we breathe out. But during an asthma attack, air gets trapped inside the lungs making it harder and harder to breathe.
