Question
Classify the statements about the gastrointestinal wall at left according to whether they are true or false True False Enteroendocrine cells are at the base of the villi, and they secrete hormones to control a wide variety of gastrointestinal functions Material absorbed by the lacteals does not reach the general circulation and instead directly exits the body in urine The gastrointestinal tract has a variety of immune functions allowing it to produce antibodies and fight infectious organisms The venous drainage from the small intestine does not empty directly into the vena cava but passes first to the spleen The human small intestine's total surface area is roughly the area of a tennis court. Most of the fat absorbed in the small intestine enters the capillary network within the center of each intestinal villus Epithelial cells that line the gastrointestinal tract are incapable of cell division Goblet cells are interspersed within the epithelium of the mucosa, and these cells secrete mucus to lubricate the wall of the small intestineExplanation / Answer
True
Gastrointestinal tract has varies immune function.it secretes antibodies and fight various infections.
Human small intestine surface area is roughly the size of the tennis court.
Goblet cells are interspersed within the epithelium of the mucosa.they secrete mucus to lubricate the wall.
False
Enteroendocrine cells are present in stomach,small and large intestine.(not only in small intestine).it produces hormones and has varied digestive functions.
Epithelial cells lining the gastrointestinal tract are capable of cell division.
Materials absorbed by lacteal reach the lymphatic system and do not exit in urine right away.
The venous drainage from the small intestine is superior mesenteric vein that joins with splenic vein to from hepatic portal vein and reaches the liver.
Most of the fat absorbed in small intestine reaches the lymphatics.
