Question
- The lymph capillaries are absent:Spinal cordHeartDermisMuscles
Solution
The lymph capillaries are absent in the following areas:
-
Spinal Cord: The spinal cord, being a part of the central nervous system, does not contain lymph capillaries. Instead, it has a specialized system for waste removal known as the glymphatic system.
-
Heart: The heart, specifically the myocardium, does not contain lymph capillaries. The lymphatic system in the heart is limited to the outer layer or the epicardium.
-
Dermis: This is incorrect. The dermis, which is the layer of skin beneath the epidermis, does contain lymph capillaries. These capillaries play a crucial role in immune response and fluid balance.
-
Muscles: This is also incorrect. Skeletal muscles do contain lymph capillaries. They play a role in draining interstitial fluid and returning it to the bloodstream.
So, the lymph capillaries are absent in the Spinal cord and Heart.
