Answer:
The blood supply provides adequate transport to calcitonin and growth hormone because it allows their distribution from the site of secretion to the whole body.
Step-by-step explanation:
Blood supply is necessary for the transport of substances needed by the body, such as oxygen, nutrients and hormones.
- Calcitonin must be transported from the C cells of the thyroid, fulfilling its function in the blood by lowering serum calcium levels.
- Growth hormone (HGH) is produced in the adenohypophysis, and must be distributed by the blood to organs such as the muscles, bones and liver, where it must fulfill its function.
The blood flow becomes an adequate transport for both calcitonin and growth hormone, since it allows it to be carried to the place where they perform their function.
