Small & Large Intestine (Photos)

Small intestine
  • Long tube that coils upon itself
  • it's the primary site of nutrient absorption
  • Its length increases contact with absorptive tissues, which optimizes nutrient absorption.
  • Small intestine subdivisions:
— Duodenum, which is relatively short, and receives chyme from the stomach. — Jejunum, which is the longer middle segment. — Ileum, which is the terminal segment of the small intestine.
Large intestine
  • Primary site of water absorption.
  • Large intestine subdivisions:
— Ascending colon, which ascends the right side of the abdomen. — Transverse colon, which passes along the transverse plane of the body. — Descending colon, which descends the left side of the abdomen. — The sigmoid colon, which is the S-shaped (aka, sigmoid) portion of the colon within the pelvis. — Cecum, which is a small, pouch-like structure. — Vermiform appendix extends from the cecum; this wormlike (aka, "vermiform") structure houses lymphoid tissue. — Rectum is the distal-most portion of the large intestine and receives the sigmoid colon.
