Question

Which hormones increases the heart beat and blood pressure

Answer 1

Hormones and glands are the foundations of the endocrine system. Hormones are chemical messengers in the body which transfer information and instructions from one set of cells to another.

The adrenaline and noradrenaline also known as epinephrine and norepinephrine are the hormones which increase the heart beat and blood pressure. They put the body on 'high alert' and control the 'fight or flight response. They increase the amount of oxygen a person breathes in and improve the eyesight temporarily.

Answer 2

The hormones that increase the heartbeat and blood pressure are epinephrine (adrenaline) and norepinephrine (noradrenaline).

Epinephrine (adrenaline) and Norepinephrine (noradrenaline) are also called as cardio-accelerators. 

The sympathetic components of the autonomic nervous system increase the heart rate by releasing the neural hormone catecholamines like epinephrine and norepinephrine.

This increase in heart rate is called as tachycardia.

Tachycardia is also caused by pulmonary bronchodilator drugs such as the sympathomimetics (Isoproterenol, Ephedrine, Bronkosol, etc.).
