FAQs on Visual Worksheet: Digestive System Antatomy - Science Class 10

1. What are the main organs involved in the digestive system?
Ans. The main organs involved in the digestive system include the mouth, esophagus, stomach, small intestine, large intestine, rectum, and anus. Accessory organs such as the liver, pancreas, and gallbladder also play crucial roles in digestion by producing enzymes and bile.
2. How does the digestive process work from ingestion to excretion?
Ans. The digestive process begins with ingestion, where food enters the mouth and is broken down by chewing and saliva. It then travels down the esophagus to the stomach, where it is mixed with gastric juices. Next, the food moves to the small intestine, where nutrients are absorbed. The remaining waste then passes into the large intestine for water absorption before being excreted through the rectum.
3. What is the function of the small intestine in digestion?
Ans. The small intestine's primary function is to digest and absorb nutrients from food. It is divided into three parts: the duodenum, jejunum, and ileum. Here, enzymes from the pancreas and bile from the liver further break down food, allowing nutrients to be absorbed into the bloodstream.
4. What role does the liver play in the digestive system?
Ans. The liver plays a vital role in digestion by producing bile, which helps emulsify fats, making them easier to digest. Additionally, the liver processes nutrients absorbed from the small intestine, detoxifies harmful substances, and stores vitamins and minerals.
5. What common diseases can affect the digestive system?
Ans. Common diseases that can affect the digestive system include gastroesophageal reflux disease (GERD), irritable bowel syndrome (IBS), Crohn's disease, ulcerative colitis, and liver diseases such as hepatitis. These conditions can lead to symptoms like abdominal pain, bloating, and changes in bowel habits.
