What is the main difference between digestion and absorption?
Answer and explanation
Correct answer: Digestion makes food simple and absorption takes it into the blood
The governing concept is the sequence of human nutrition. Digestion is the mechanical and chemical breakdown of complex carbohydrates, proteins and fats into smaller soluble molecules. Absorption is the movement of these digested nutrients through the intestinal wall, mainly in the small intestine, into blood or lymph. Hence option A is correct; the other choices assign circulatory, excretory or respiratory functions incorrectly.
