The video explains how the small intestine plays a crucial role in the absorption of nutrients after digestion breaks down large food molecules into smaller ones. It highlights the function of villi in increasing surface area for absorption and describes how nutrients like sugars, amino acids, fatty acids, and glycerol are absorbed into the bloodstream through diffusion.
