Enterochromafin cells in the alimentary canal
fiber
this is because the alimentary canal consists of parts which the food flow into the bolus hence it needs to be sliding into the alimentary canal until it come to be digested.
Mucus is secreted so that peristalsis can occur and can slide easily down you throat.
Mucus produced by cells which line the digestive tract.
No. Plasma is a blood component. The stomach is made up of specialized cells...and is part of the alimentary canal.
glucose
Nutrients are absorbed into the bloodstream. Starch is broken down by enzymes. Macromolecules are broken down.
Electrons transfer energy from glucose to other molecules during redox reactions in cells.
Electrons transfer energy from glucose to other molecules during redox reactions in cells.
Passive diffusion is a method by which glucose molecules enter cells. Glucose can diffuse through the cell membrane down its concentration gradient without the need for energy input from the cell.
GLUT transporters allow glucose to move down its concentration gradient in the capillaries to the cells where it is needed.
