Consider the following statements each with one or two balnks.
(i) The bile duct and the pancreatic duct open together into the duodenum as the (1) which is guarded by a sphincter called the (2)
(ii) (3) is a proteolytic enzyme found in gastric juice of infants which hleps in the digestion of milk proteins.
(iii) Fatty acids and glycerol being insoluble, cannot be absorbed into the blood. They are first incorporated into small droplets called (4) which move into the intestinal mucose. They are re-formed into very small protein coated fat globules called the (5) which are transported into the lymph vessels (lacteals ) in the villi.
Which of the folllowing options gives the correct fill ups for the respective blanks in the above statements?

Options

A. (1)-common bile duct, (2)-sphincter of Boyden, (3)-Pepsin
B. (3) Rennin,(4)-chyme, (5)-micelles
C. (1)-Common hepato-pancreatic duct, (2)-sphincter of Oddi, (4)-micelles, (5)-chylomicrons
D. (3)-Casein,(4)-chylomicrons,(5)-micelles

Explanation

To solve the question, we need to fill in the blanks in the given statements with the correct terms related to digestion and absorption. Let's go through each statement step by step.

### Step-by-Step Solution:

1. **Statement (i)**: The bile duct and the pancreatic duct open together into the duodenum as the **(1)** which is guarded by a sphincter called the **(2)**.
- **(1)**: The correct term for the structure where the bile duct and pancreatic duct open into the duodenum is the **common bile duct**.
- **(2)**: The sphincter that regulates the flow of bile and pancreatic juices into the duodenum is called the **sphincter of Oddi**.

2. **Statement (ii)**: **(3)** is a proteolytic enzyme found in gastric juice of infants which helps in the digestion of milk proteins.
- **(3)**: The proteolytic enzyme that helps in the digestion of milk proteins in infants is known as **renin**.

3. **Statement (iii)**: Fatty acids and glycerol being insoluble, cannot be absorbed into the blood. They are first incorporated into small droplets called **(4)** which move into the intestinal mucosa. They are re-formed into very small protein-coated fat globules called the **(5)** which are transported into the lymph vessels (lacteals) in the villi.
- **(4)**: The small droplets formed from fatty acids and glycerol are called **chylomicrons**.
- **(5)**: The very small protein-coated fat globules that are transported into the lymph vessels are also referred to as **micelles**.

### Final Answers:
1. (1) Common bile duct
2. (2) Sphincter of Oddi
3. (3) Renin
4. (4) Chylomicrons
5. (5) Micelles

### Summary of the Correct Fill-Ups:
- (1) Common bile duct
- (2) Sphincter of Oddi
- (3) Renin
- (4) Chylomicrons
- (5) Micelles
