Where is digested food absorbed into the blood in the human body?

The Answer is Small intestine.

Explanation:

The dietary intake of food begins in the buccal cavity (mouth). Food particles are mixed with saliva, secreted by the salivary glands located at the ends of the buccal cavity. Saliva helps in the emulsification of food.

The tongue pushes the chewed food from the mouth into the esophagus, where it passes down to the stomach through peristaltic movements (wave-like muscular contractions).

In the stomach, food is churned and mixed with gastric juices (including hydrochloric acid, enzymes like lipases, etc.), which break down complex molecules into simpler forms for easier absorption.

The partially digested food then enters the small intestine, where tiny hair-like projections called villi absorb essential nutrients. These nutrients are mixed with blood and transported throughout the body for energy and growth.

After nutrient absorption, the remaining undigested food passes into the large intestine, where water and any remaining nutrients are reabsorbed into the blood.

Finally, the leftover waste material is eliminated from the body through the rectum and anus.
