The secretory changes in the stomach, characterized by more intensive secretion of gastric juices, lowered pH, and elevated pyloric tone under the microgravity environment, may be related to changes in the venous hemodynamics of the abdominal organs (Afonin, 2013). In another study by Afonin ...
(esophagus: all five cell clusters; stomach: gastric chief, neck, parietal, pit and differentiating cells; duodenum: stem and transit-amplifying cells as well as immature and mature enterocytes) and less than 30% of the main tissue-specific cell types in the other two organs, it was ...
Consistent with the expression pattern of the SIDT1 protein, plant miR156a, miR168a and miR2911 were highly enriched in the stomach compared to other organs in the GI tract of mice on a regular chow diet or after gavage feeding of synthetic dietary miRNAs (Fig. 4a–c). Fig. 4: SIDT1...
Explain how the structures of the organs of the male and female reproductive systems relate to their functions. Explain how the structure of the major types of tissue relates to their function. Why are villi not present in the stomach? What is the main function of digestion? How are the...
The stomachs of some other animals differ considerably from that of humans; many have multiple-chambered organs or special adaptations. The stomachs of cows and most cud-chewing (ruminant) animals are divided into four separate parts. Food is received first in the rumen, where mucus is added an...
