Nutrient Absorption

Topic

Nutrient absorption is the physiological process by which digested food molecules, water, and essential minerals are taken up from the gastrointestinal tract into the bloodstream or lymphatic system. This vital process occurs primarily in the small intestine, where specialized structures like villi and microvilli maximize surface area to facilitate efficient uptake. The absorbed nutrients are then transported throughout the body to support cellular function, energy production, and overall growth.
