Answer:
Key players in calcium balance involving calcium entry and exit in the body are calcium and phosphate, which are integral for bone health and as reserves within the skeletal system.
Step-by-step explanation:
The key players in calcium balance of calcium entry and exit are calcium and phosphate. These two are among the most important electrolytes in living systems and play a crucial role in various bodily functions. Calcium and phosphate are vital for bone and teeth formation since more than 90% of the calcium and phosphate that enters the body is incorporated into these structures. Additionally, electrolytes like sodium, potassium, and chloride are significant in terms of body water distribution and retention. In terms of hormonal regulation, sodium and potassium levels are most affected by aldosterone, a hormone involved in balancing electrolytes in the body.
In summary, while many electrolytes contribute to overall balance, calcium and phosphate are specifically crucial for calcium balance in the body. These macrominerals form an integral part of bone structure and are bound within the skeletal system, with the bones serving as a reserve for these elements.
