Question

Quizplus · Accepted Answer

Diffusion and active transport are key mechanisms in the absorption of nutrients from the digestive tract into the bloodstream. Diffusion allows for the passive movement of substances from an area of higher concentration to one of lower concentration, while active transport requires energy to move substances against their concentration gradient. Both processes are crucial for efficiently absorbing digested food molecules.
