In humans, increased rate of heartbeat is due to the release of ______ into the bloodstream.
The correct option is A adrenaline
Adrenaline or ephinephrine is a steroid hormone secreted by the adrenal medulla (inner portion of the adrenal gland). Adrenaline specifically regulates SA node which increases heartbeat in emergency conditions to cope up with increased blood supply to the organs.
Parathormone secreted by the parathyroid gland regulates calcium homeostasis in the body. Growth hormone is released into the bloodstream from the anterior pituitary gland. Growth hormone acts on many parts of the body to promote growth in children. Thyroxine is the main hormone produced by the thyroid gland, acting to increase metabolic rate and regulating growth and development.
