Question

Describe the role of Na + and Ca + + in human physiological system​

Answer 1

Explanation:

• In humans, sodium plays a key role in the regulation of blood volume, blood pressure, osmotic balance and maintain a constant pH. Sodium is also essential for the functioning of neurons and osmoregulation between cells and the extracellular fluid. In humans, this process is regulated by the Na+/K+ pump.
• Calcium ions (Ca2+) contribute to the physiology and biochemistry of organisms cell. They play an important role in signal transduction pathways, where they act as a second messenger, in neurotransmitter release from neurons, in contraction of all muscle cell types, and in fertilization.
