Gastro-Intestinal Hormones of Human Body | Digestive System | Biology

In this article we will discuss about the interactions and metabolic effects of gastro-intestinal hormones. Interactions of Gastro-Intestinal Hormones: As gastrin stimulates acid secretion, it probably combines with specific receptor sites on the effector cells. When the concentration of gastrin is high, many receptor sites are occupied and when this concentration is low, few receptor sites are occupied. This relationship [...]

Secretions in the Gastro-Intestinal Tract | Digestive System | Human | Biology

The various humoral (chemical) factors controlling the different secretions in the gastro-intestinal tract may be summarised as follows: 1. For Gastric Secretion: i. Gastrin- Responsible for gastric phase. ii. A chemical substance may be a hormone or secretagogue - Responsible for intestinal phase. iii. Enterogastrone- Inhibits gastric secretion. 2. For Pancreatic Secretion: i. Secretin- Main chemical stimulus. ii. Pancreozymin. iii. [...]

Mechanism of Bile Storage | Digestive System | Human | Biology

In this article we will discuss about the mechanism of bile with the help of suitable diagram. Bile secretion by liver is an active and continuous process, but its expulsion in the duodenum is intermittent. These facts necessarily prove that after secretion bile must be stored somewhere. The gall-bladder is the chief place for bile storage. The common bile duct, [...]
