Which type of membrane has two layers with fluid between to reduce friction when organs move?Group of answer choicesSynovial MucousCutaneousSerous

Break Down the Problem

1. Identify the types of membranes listed in the question.
2. Determine which membrane type has a fluid-filled layer that reduces friction between moving organs.

Relevant Concepts

• Synovial Membrane: Lines joints and produces synovial fluid, which lubricates the joints.
• Mucous Membrane: Lines cavities that open to the exterior of the body and secretes mucus.
• Cutaneous Membrane: Refers to the skin, which is a protective layer.
• Serous Membrane: Lines closed body cavities and secretes serous fluid, which reduces friction between organs.

Analysis and Detail

• The synovial membrane is specific to joints and has a significant role in reducing friction during movement.
• The serous membrane consists of two layers (parietal and visceral) and secretes fluid in the spaces between these layers. This fluid also helps to reduce friction when organs move, particularly in the thoracic and abdominal cavities.

Verify and Summarize

Upon examining the functions of each membrane, it is clear that the serous membrane fits the description given in the question.

Final Answer

The type of membrane that has two layers with fluid between to reduce friction when organs move is the Serous membrane.
