Pregunta Respuesta
Adaptations of the Villi
Adaptation 1: Has microvilli - these create a larger surface area which help for a more rapid absorption
Adaptation 2: Thin surface layer - this helps to create a short diffusion pathway so the small soluble molecules can diffuse into the villi quicker and more efficiently
Adaptation 3: Good blood supply via capillary network - this allows soluble material to be transported away very quickly maintaining a concentration gradient
