Cerebrospinal fluid of the central nervous system and synovial fluid of joint capsules are both examples of <u>extracellular </u><u>fluid</u>
- Extracellular fluid called cerebrospinal fluid is present throughout the CNS
- It acts as a protective layer for CNS ftom injury and shock
- Cerebrospinal fluid is clear, colorless fluid produced by the choroid plexus.
- It surrounds the brain and spinal cord.
Synovial fluid is a viscous solution found in cavities of synovial joints. The principal role of synovial fluid is to reduce friction between articular cartilages of synovial joints during movement.
- Synovial fluid is a small component of transcellular fluid component of extracellular fluid.

Homeostasis is defined as a constant, steady environment despite external changes, such as exercise. Exercise affects your body temperature, blood oxygen levels, sugar levels and hydration – all properties necessary for your survival. Your body uses an automatic feedback system to preserve normal temperature and water levels, so you can keep exercising. Eat properly and drink plenty of fluids to help your body maintain homeostasis. You need to drink and eat properly.
B trench
Explanation:
The feature found at most convergent margins is a trench.
A trench is a large depression that typifies most convergent margins.
- Oceanic trenches are natural topographic depressions found on the sea floor.
- These depressions forms where two plate boundaries converges.
- The denser one slides beneath the less dense one into the asthenosphere below.
- This is called a subduction zone.
- The margin between the two plates that are depression is a trench.
