Describe what happens to a meal of oily beans and maize from the time of ingestion up to the time of aborption
alexgriva [62]

Food is chewed and mixed by the teeth and tongue before being rolled into boluses by peristalsis and entering the stomach through the cardiac sphincter. In the stomach, gastric juice contains pepsinogen, which is activated to pepsin, which breaks down proteins in beans into shorter peptides. Finally, food is churned and allowed into the duodenum via the pyloric sphincter muscle. Finally, bile Trypsin breaks down proteins into shorter peptides, and pancreatic juice, which is released by the pancreas, contains pancreatic lipase, which breaks down bean oil into fatty acids and glycerol. When food enters the ileum, where succus entericus is secreted, it contains the enzymes maltase, peptidase, and lipase, which break down the remaining lipids (oil) into fatty acids and glycerol, which are then absorbed through the lacteals of the villi. Maltase breaks down maltose into glucose, which is then absorbed.

The Digestion and Absorption Process

Even before you put food in your mouth, digestion starts. Your body notifies your brain that it is time to eat when you feel hungry. Your body's ability to prepare for eating is influenced by sights and odours. Your brain receives a message when you smell food. The mouth is subsequently instructed by the brain to prepare, and you begin to salivate in anticipation of a mouthwatering meal.

Which statement best describes how the structure of the alveoli allows the lungs to function properly
zlopas [31]

Out of the following given choices;

a. they increase the amount of energy transferred from the lungs to the blood

b. they increase the flexibility of the lungs as they expand during inhalation

c. they increase the volume of the lungs, allowing more oxygen to be inhaled

d. they increase the surface area of the lungs, allowing the efficient gas exchange

The answer is D. Due to their microscopic nature, they are numerous in the lungs and are also circular-shaped so as to increase the surface area for gaseous exchange. Other characteristics of alveoli that increase gas exchange are that they thinned-walled (with only a layer of cells) and moist.
