Multiple Choice
In the context of the integumentary system, where is fat primarily located in a frog's body?
A
Directly beneath the outermost layer of the skin
B
Within the muscle tissue of the limbs
C
In yellowish fat bodies within the abdominal cavity
D
Surrounding the heart and lungs in the thoracic cavity
Verified step by step guidance

Understand the integumentary system: The integumentary system includes the skin and its associated structures, such as glands, hair, and nails. In frogs, fat storage is not directly part of the integumentary system but is closely related to energy storage and metabolism.
Identify the primary location of fat storage in frogs: Fat is stored in specialized structures called fat bodies, which are yellowish and located within the abdominal cavity. These fat bodies serve as energy reserves, especially during periods of hibernation or reproduction.
Eliminate incorrect options: Fat is not stored directly beneath the outermost layer of the skin, as this area primarily contains connective tissue and blood vessels. It is also not stored within the muscle tissue of the limbs, as muscles are primarily composed of muscle fibers and connective tissue.
Clarify the role of fat bodies: Fat bodies are distinct from other areas of the body, such as the thoracic cavity surrounding the heart and lungs. While the thoracic cavity contains vital organs, it is not a primary site for fat storage in frogs.
Conclude the correct answer: Fat is primarily located in yellowish fat bodies within the abdominal cavity, which are specialized for energy storage and metabolic functions.
