Q96. What are the parts of the stomach?

Ans. The stomach has four main parts: the fundus, the body, the pylorus, and the antrum. The fundus is the upper part of the stomach that curves upward and toward the chest. The body is the main part of the stomach and is where most digestion occurs. The pylorus is the lower part of the stomach that connects to the small intestine. The antrum is the very bottom part of the stomach.

Q97. How does the stomach work?

Ans. The signs of kidney failure include fatigue, decreased urination, swelling in the ankles and feet, and difficulty breathing.

Q107. What is the pancreas?

Ans. The pancreas is a gland that produces enzymes that help to digest food. It is located in the abdomen behind the stomach.

Q108. What are the parts of the pancreas?

Ans. The pancreas has two main parts: the head and the tail. The head of the pancreas is located near the duodenum, while the tail is located near the spleen.

Q109. How does the pancreas work?

Ans. The pancreas works by producing enzymes that help to digest food. These enzymes are released into the small intestine where they help to break down carbohydrates, fats, and proteins.

Q110. What are the intestines?

Ans. The intestines are a long, coiled tube that runs from the stomach to the anus. They are responsible for absorbing nutrients from food and passing waste products out of the body.

Q111. What are the parts of the intestines?

Ans. The intestines have two main parts: the small intestine and the large intestine. The small intestine is responsible for absorbing nutrients, while the large intestine absorbs water and passes wastes out of the body.

Q112. How do the intestines work?

Ans. The intestines work by absorbing nutrients from food and passing waste products out of the body. Nutrients are absorbed through the walls of the small intestine into the bloodstream, while wastes are passed through the large intestine and out of the body as feces.

Q113. What is the bladder?

Ans. The bladder is a sac-like organ that stores urine. It is located in the pelvis, just behind the pubic bone.

Q114. How does the bladder work?

Ans. The bladder works by storing urine until it is full, at which point it contracts and empties urine through the urethra and out of the body.
