Document Summary
Peristalsis - contraction of longitudinal and circular muscle. The abdominal muscles push your food upwards in case of regurgitation. Layers: serosa (octercoat/ direct absorption, muscular -longitudinal muscles. Circular muscles: submucosa: contains blood vessels + lymph vessels (transport layer, mucosa (surface/ lining of the small intestine made by epithelial cells) Enzymes secreted by pancreas carry out catabolic reactions (hydrolysis). Exopeptidase: an exopeptidase is any peptidase that catalyzes the cleavage of the terminal (or the penultimate) peptide bond; the process releases a single amino acid or dipeptide from the peptide chain. Endopeptidase: an enzyme that breaks peptide bonds other than terminal ones in a peptide chain.
