Endocrine disruptor hormones. The interrelationship between exposures to chemicals and health effects are rather complex. It is hard to definitively link a particular chemical with a specific health effect, and exposed adults may not show any ill effects. But, fetuses and embryos, whose growth and development are highly controlled by the endocrine system, are more vulnerable to exposure and may suffer overt or subtle lifelong health and/or reproductive abnormalities. Prebirth exposure, in some cases, can lead to permanent alterations and adult diseases. Some in the scientific community are concerned that exposure to endocrine disruptors in the womb or early in life may
Gastric glands neck cells" that produce mucus. This is thought to be different from the mucus produced by the gastric mucosa. Fundic glands found in the fundus and also in the body have another two cell types–gastric chief cells and parietal cells (oxyntic)). The chief cells are found in the basal regions of the gland and release a zymogen – pepsinogen, a precursor to pepsin. The parietal cells ("parietal" means "relating to a wall") are found in the walls of the tubes. The parietal cells secrete hydrochloric acid–the main component of gastric acid. This needs to be readily available for the stomach
