Which spaghetti-shaped structures provide protection, insulation, buoyancy and contribute cholesterol to the frog?

• A. Liver
• B. Spleen
• C. Fat body
• D. Pancreas

Answer: (C)

Fat bodies in frogs are the lipid storage tissues that serve as energy reserves and also contribute to insulation and buoyancy. These spaghetti-like strands surround the digestive organs and gonads, packed with fats that the frog can draw on during periods of activity, metamorphosis, or hibernation. The fat content lowers overall density, aiding buoyancy in aquatic environments, and provides insulation in cooler water. Lipids in these stores include cholesterol, which the frog can mobilize for membrane synthesis and steroid hormone production when needed. Other organs have different primary roles—metabolism and detoxification for the liver, immune filtering for the spleen, and digestive enzyme production for the pancreas—so they don’t serve as this concentrated lipid reservoir.
