Question 124

To determine which salivary gland produces only mucus - type saliva:

• Parotid glands produce serous - type saliva (watery with enzymes).
• Submandibular glands produce a mixed (serous and mucous) saliva.
• Sublingual glands produce mainly mucus - type saliva. So the correct option is Sublinguals.

To identify the part of the colon:

• Ascending colon is on the right side, ascending.
• Transverse colon is horizontal, across the abdomen.
• Descending colon is vertical, on the left side, extending from below the stomach/spleen to the iliac crest.
• Sigmoid colon is the S - shaped part near the rectum. So the correct option is descending.

To find the longest part of the small intestine:

• Duodenum is the first, shortest part of the small intestine.
• Jejunum is the middle part.
• Ileum is the longest part of the small intestine.
• Colon is part of the large intestine. So the correct option is ileum.

Answer:

A. Sublinguals
