Introduction:
Digestive system in humans consists of gastrointestinal tract and accessory organs. The organs mainly involved in the digestive system are salivary glands, pharynx, esophagus, stomach, rectum, small, and large intestine.
Explanation of Solution
Most of the microorganism enter into the human body through a portal of entry and cause disease. Mostly microorganism enters through the skin, respiratory tract, digestive tract, and genitourinary tract. The skin is the largest organ in the body and several micro-organisms are present in the skin. But, they cannot enter into the skin. Through the respiratory tract, microorganism spread during inhalation. When compared to the other portal entry, the important portal of entry for the microorganism is digestive tract. The digestive system is infested by eating contaminated food and drinking water, which enter the digestive tract and cause disease. For example, typhoid and cholera.
The important portal entry of the microorganism is through the digestive system.
