医学英语消化系统图文解说
pancreas are called accessory digestive glands?
Text Study——Part 1
1. What are other terms for digestive tract?
Digestive tract is also termed as gastrointestinal tract, alimentary canal or gut(消化道).
They are also known as accessory organs, because they are not part of the digestive tract, yet have a role in digestive activities.
Unit Two
The Digestive System
Objectives
In this unit, we are going to learn to:
1. Grasp some medical terms related to digestive system.
2. Describe the function of the digestive system, and differentiate between organs of the alimentary canal and accessory digestive organs；
Text Study——Part 1——Translation
There are many people who are waiting to be admitted to the hospital ward.
许多人在等着入院。
Fat-soluble vitamins, which include vitamins A,D,E, and K, are usually absorbed with the help of foods that contain fat.

laboratory examination
Barium meal（钡餐） Barium studies of the proximal gastro-intestinal tract are still commonly used as a first test for documenting an ulcer. For a DU ,it appears as a welldemarcated crater, often seen in the bulb . For a GU ,it may represent benign or malignant disease. Typically,a benign GU also appears as a discrete crater with radiating mucosal folds originating from the ulcer margin . （GU可能是良性和恶性。典型的良性表现为 游离龛影，粘膜皱襞从溃疡边缘向内放射集 中）
