1) What process allows digested food to pass into the blood vessels in...
Explanation:
Absorption: The process by which digested food passes into the blood vessels in the wall of the intestine is called absorption. During the process of digestion, the food is broken down into simpler substances by the action of digestive juices. These simpler substances such as glucose, amino acids, fatty acids, and glycerol are then absorbed by the blood vessels in the wall of the intestine.
The process of absorption involves the following steps:
- After digestion, the food is in the form of a liquid called chyme.
- The chyme moves from the stomach into the small intestine.
- In the small intestine, the chyme mixes with digestive juices from the pancreas and liver.
- The walls of the small intestine are lined with millions of tiny finger-like projections called villi.
- The villi increase the surface area of the intestine and help in absorption.
- The nutrients from the chyme are absorbed by the blood vessels in the villi and transported to the liver through the hepatic portal vein.
- The liver processes the absorbed nutrients and sends them to the rest of the body through the bloodstream.
Conclusion: Hence, the correct option is (d) Absorption.
