Question

______________causes dilation of blood vessels, increased oxygen consumption and glucogenesis.

Answer 1

Adrenaline:

1. Adrenaline is a hormone secreted by the adrenal medulla of the adrenal gland situated on both the kidneys.
2. It is also known as the fight or flight hormone or stress hormone as it initiates the stress response in the body.
3. These hormones affect smooth muscle, blood vessels, skeletal muscles, and fat cells.
4. As this hormone is to prepare the body for stress, it increases the heartbeats, and blood pressure and dilates the blood vessels, increasing breathing rate and hence oxygen consumption and glycogenesis to increase the blood sugar level.

Final answer: Adrenaline causes dilation of blood vessels, increased oxygen consumption, and glucogenesis.
