Movements of Stomach: 4 Types | Organs | Human Body | Biology

In this article we will discuss about the four main types of movements that are seen in stomach. Type # 1. Movements of the Fundus and Body: A peristaltic wave follows the basic electrical rhythm (B.E.R.) of stomach. It starts in the longitudinal mus­cle of greater curvature as a pacemaker and passes over the body, antrum and pylorus at a [...]

Act of Swallowing in Human Body (With Diagram) | Digestive System | Biology

Deglutition or swallowing is probably a reflex phenomenon. Higher centres facilitate this reflex. Once aroused, the swallowing centre in the medulla evokes the complete act of swallowing by discharge through six nuclei and the motor neurones. This reflex act occurs in three stages: (1) First or oral, (2) Second or pharyngeal, and (3) Third or oesophageal (Fig. 9.46). (1) First [...]

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 [...]
