The respiratory system allows for gas exchange to happen in the lungs. How does the respiratory system affect the cardiovascular
Charra [1.4K]
The answer is <span>The respiratory system supplies the oxygen that the cardiovascular system transports to the different cells for the production of energy. 

When air enters the lungs (part of the respiratory system), it passes all way to the alveoli, the smallest functional units of the lung. There, oxygen from the air enters the capillaries, the smallest blood vessels, next to the alveoli. Once in the blood stream, the cardiovascular system transports oxygen to different cells where it is used for the energy production.</span>

Leni [432]

C cells of the thyroid gland secrete calcitonin.

<h3>What does C cells of thyroid gland produce?</h3>
  • The thyroid follicle, which is the gland's active component, is encircled by a single layer of epithelial cells, and the lumen is stuffed with colloidal material.
  • It includes parafollicular cells, or C cells, which release calcitonin.
  • The C-cells of the thyroid gland secrete calcitonin, a 32 amino acid hormone.
  • When the concentration of blood calcium has grown over the usual range, the thyroid gland releases the hormone calcitonin, which lowers the level.
  • The parafollicular cells, sometimes referred to as the C cells, of the thyroid gland are the principal producers of this polypeptide hormone, which has 32 amino acids.
