Explanation

The lungs are the primary organs responsible for breathing.

They allow oxygen to enter the body and carbon dioxide to be expelled.

The heart circulates the oxygenated blood, but the lungs are where the exchange of gases takes place.

Explanation

• The small intestine, also known as the small bowel, is the primary site of nutrient absorption in the human body.
• The walls of the small intestine are lined with finger-like projections called villi, which increase the surface area for absorption.
• Nutrients like carbohydrates, proteins, fats, vitamins, and minerals are absorbed into the bloodstream through the small intestine.
