Answer:
Parathyroid hormone increases the level of calcium while calcitonin hormone decreases the level of calcium in the blood.
Explanation:
Parathyroid hormone is a type of harmone which is responsible for balancing calcium in our body. When the calcium level lowers in our body, parathyroid hormone is secreted and calcium is absorbed from the bones and fullfilled the requirement of the body.

Answer:
Astrocytes
Explanation:
Astrocytes are specialized glial cells found in the brain and spinal cord, they are responsible for maintaining the electrolytic composition of the cerebrospinal fluid, induce the formation of the blood-brain barrier and act as a support and guide for neurons during migration. They keep the ionic composition of the extracellular fluid of the central nervous system through the water channels, Aquaporin-4 (AQP4) and K channels, located in the pedicle processes of the astrocytes in the perivascular space, these cells exchange K and water in said perivascular medium away from the neurons. Astrocytes selectively edematize during hypotonic stress, while neurons do not.
