Full Explanation
Chylomicrons are indeed secreted from the basal surface of the intestinal absorptive cells (enterocytes) and are absorbed into the lacteals, which are lymphatic vessels in the villi of the small intestine.
Similar Questions
Amino acids and monosaccharides are absorbed in the______________ and fatty acids are absorbed in the_____________
A. small intestine; small intestine
Small intestine; small intestine: Both amino acids and monosaccharides are absorbed in the small intestine, and fatty acids are also absorbed in the small intestine, where they are reassembled into triglycerides and incorporated into chylomicrons.
B. small intestine; liver
Small intestine; liver: Amino acids and monosaccharides are absorbed in the small intestine, but fatty acids are absorbed in the small intestine, not directly in the liver.
C. stomach; small intestine
Stomach; small intestine: Amino acids and monosaccharides are absorbed in the small intestine, not the stomach, and fatty acids are absorbed in the small intestine, not the stomach.
D. stomach; large intestine
Stomach; large intestine: Amino acids and monosaccharides are absorbed in the small intestine, and fatty acids are absorbed in the small intestine, not the stomach or large intestine.

What are the major chemical buffer systems of the body?
A. The bicarbonate, phosphate, and protein
The bicarbonate, phosphate, and protein: The major chemical buffer systems in the body are the bicarbonate buffer system, the phosphate buffer system, and the protein buffer system. These buffers help maintain pH balance in the blood and other fluids.
B. The urinary and digestive
The urinary and digestive: The urinary and digestive systems are involved in excretion and digestion, not buffering.
C. The bicarbonate, nucleic acids, and protein
The bicarbonate, nucleic acids, and protein: Nucleic acids are not major buffering systems in the body; the bicarbonate, phosphate, and protein systems are the primary ones.
D. The urinary and respiratory
The urinary and respiratory systems play roles in regulating acid-base balance through excretion and gas exchange but are not chemical buffer systems themselves.
