💪Calcium determines the contractile ability of our heart and muscles.
🧠The amount of calcium in our blood affects how our nerves work.
👥Parathyroid glands release parathyroid hormone (PTH) to regulate blood calcium levels.
☀️UV light from the Sun helps in the production of vitamin D, which is vital for calcium absorption.
⚖️Calcium homeostasis involves a negative feedback loop to maintain a tightly regulated amount of calcium in the bloodstream.
Why is calcium important for our body?
—Calcium is essential for the proper functioning of our heart, skeletal muscles, and nerves.
How is calcium regulated in our body?
—Calcium is regulated through a process called calcium homeostasis, which involves parathyroid hormone and vitamin D.
What role do parathyroid glands play in calcium regulation?
—Parathyroid glands release parathyroid hormone (PTH) to regulate blood calcium levels.
How does vitamin D affect calcium absorption?
—Vitamin D helps in the absorption of calcium from the intestines into the bloodstream.
What is calcium homeostasis?
—Calcium homeostasis is the process of maintaining a tightly regulated amount of calcium in the bloodstream through a negative feedback loop.
