MT 30 – J (LAB) | S.Y '23-'24 1 year, 7 months ago Activity 5: Digestive System
Medium: Color pencil
Description: 📚
The digestive system is where food travels and gets digested. The food is broken down physically and chemically into simpler bits. The nutrients and water are then absorbed, while waste products are combined with the leftover materials and disposed of out of the body. The system comprises the digestive tract (mouth, esophagus, stomach, small intestine, and large intestine) and the associated organs (salivary glands, pancreas, liver, teeth, and gallbladder).
Portrayed tissues: 🎨
The pancreas (1) is an accessory organ that produces digestive enzymes (lipase, amylase, and protease) that break down food.
The jejunum (2) is the middle segment of the small intestine. It has specialized structured epithelial cells designed for maximal absorption.
The tooth (3) is another accessory organ. It is covered with hard enamel and plays a major role in mastication.
Appendix (4) is attached to the first part of the large intestine. It is believed to house beneficial microbes.
The stomach cardia (5) is the stomach region closest to the esophagus. It helps prevent food from returning up the esophagus.
The tongue (6) is a muscular process in the mouth that aids in mastication and swallowing.
The liver (7) is composed of hepatocytes and one of its functions is to detoxify harmful substances in the body. It then sends this broken-down waste to the intestinal tract along with the bile.
The ileum (8) is the last segment of the small intestine. It has specialized structured epithelial cells designed for maximal absorption.
The tonsils (9) are technically part of the lymphatic system but they are also considered to be accessory organs in the digestive system. They help protect the tract by killing pathogens.
Lastly, the parotid glands (10) produce saliva that lubricates the mouth. This helps in mastication.
