- The main pathogenesis and etiology of digestive illnesses can spread from a variety of causes
- Bacterial and viral infection: many gastrointestinal diseases such as stomach ulcers, gastritis, and stomach cancer can be caused by the bacteria known as Helicobacter pylori. This bacteria infects the stomach and affects the mucous lining and generates substances that neutralizes the stomach's lining. When this happens, it causes the stomach to be more vulnerable to the harsh acids. A combination of stomach acid and
H. Pylori together irritates the stomach lining, leading to ulcers in the stomach or duodenum.
- Parasites like roundworms and tapeworms etc. For example, roundworms also known as Ascariasis is a type of infection of roundworms one gets in the intestines. Roundworms are contacted through the worm’s eggs through food, soil or water.

The function of this portal system is to carry nutrients from the digestive tract to the liver after a meal to store and metabolize.
The liver's main job is to filter the blood coming from the digestive tract, before passing it to the rest of the body. The liver also detoxifies chemicals and metabolizes drugs. As it does so, the liver secretes bile that ends up back in the intestines. The liver also makes proteins important for blood clotting and other functions. What is the main function of the liver? a. filter the blood from the digestive tract, before passing it to the rest of the body.
b. detoxifies chemicals and metabolizes drugs. c. secretes bile that ends up back in the intestines. d. make proteins important for blood clotting and other functions. https://www.youtube.com/watch?v=P5_BxsbmXcA&t=14s https://www.youtube.com/watch?v=jiIIYo7NAoU ,
