Course Description

Welcome to the comprehensive course on Gastrointestinal Physiology. This course stretches over 13 hours and 16 minutes, perfectly blending depth and clarity to explore intricate aspects of gastrointestinal health and physiology.

If you're delving into the field of health, with a specific focus on physiology, this course is tailored just for you. It unfolds the complexities of the gastrointestinal system in a structured and engaging manner, making it accessible for learners at various levels of expertise.

We'll start our journey with the anatomy of the teeth, delving into their critical role in the initial stages of digestion. From there, we'll examine the role of major salivary glands like the parotid and submandibular glands in salivation, setting the stage for efficient breakdown of food.

Next, we transition to the nuanced process of deglutition, commonly known as swallowing, dissecting the coordination between muscles and nerves that make this vital function possible.

The course then takes a deep dive into the phases of gastric secretion. We start with the cephalic phase, exploring how the mere sight and smell of food can trigger digestive processes. We will then move on to the intestinal phase, focusing on how food entering the intestines further influences gastric secretions.

An extensive section is dedicated to liver histology and liver circulation. This intricate organ's microarchitecture and its pivotal circulatory systems are thoroughly examined to understand their roles in overall digestive health.

The liver's multifaceted functionalities are also dissected, including its metabolic processes and protein synthesis capabilities. One of the critical functions of the liver, the biotransformation of drugs and toxins, will be explained to highlight its role in detoxifying the body.

Bile synthesis and its significance in digestion will also be covered, providing insight into how the liver assists in the emulsification and absorption of lipids. Furthermore, the pathophysiology of different types of jaundice will be explored, aiding in the understanding of liver-related disorders.

Our examination of gastrointestinal motility spans different sections of the gastrointestinal tract, including the esophagus, small intestine, and large intestine. Here, we will elucidate the coordinated muscular contractions facilitating the movement of food and waste.

We'll explore the enteric nervous system, sometimes referred to as the "second brain," and its regulatory functions over gastrointestinal activities, also emphasizing its interaction with the central nervous system.

In the concluding segments, we analyze the intricate process of digestion—in its various stages—by breaking down how nutrients are decomposed and absorbed into the system.

Although no reviews are available yet, this course promises to be a cornerstone resource for anyone aiming to gain a comprehensive understanding of gastrointestinal physiology. Embark on this educational adventure and gain the clarity and expertise you need in gastrointestinal physiology.
