Answer:
1. Villi are specialized for absorption in the small intestine as they have a thin wall, one cell thick, which enables a shorter diffusion path. They have a large surface area so there will be more efficient absorption of fatty acids and glycerol into the blood stream.
2. Ribs – The intercostal muscles stretch between the ribs which causes its outward and inward movement which enlarges the chest cavity all around.
3. Roughage has numerous health benefits. It helps improve digestion and promotes gut health. It may also improve certain risk factors for heart disease and help you manage your weight and blood sugar.
4. The epiglottis is a small, movable "lid" just above the larynx that prevents food and drink from entering your windpipe.
5. Diaphragm – The diaphragm flattens from the dome-shaped outline to an almost horizontal plane upon contraction
6. The tongue (L. lingua; G. glossa) functions as a digestive organ by facilitating the movement of food during mastication and assisting swallowing. Other important functions include speech and taste.
