Which hormone causes dilation of blood vessels, increased oxygen consumption and an increase in blood glucose levels?
Adrenaline
Adrenaline is a hormone secreted by the adrenal medulla. It prepares the body to face special conditions created by physical stress. Adrenaline provides the body with extra energy by increasing heartbeat, blood pressure and respiratory rate. It also increases the blood glucose levels by stimulating the breakdown of liver and muscle glycogen into glucose.
