Answer:
High Blood Pressure. Hypertension increases one’s risk of cardiovascular disease as the blood vessel walls become irritated by the increased pressure exerted by the blood flowing through. As more and more damage is done to the vessel walls, plaque tends to form, in turn increasing the likelihood of atherosclerosis and coronary heart disease.
Answer:
The correct option is : a. causing threshold to be reached more quickly
Explanation:
Norepinephrine, also known as noradrenalin, is an organic compound, which belongs to the catecholamine family. It acts as a hormone and a neurotransmitter in the brain and the body and also impacts the heart.
It is one of the hormones secreted by the adrenal medulla. Norepinephrine is a part of the fight-or-flight mechanism of the body. It acts by binding to the β-1 receptors and opens the chemical or ligand gated calcium and sodium ion channels. Therefore, <u>it causes the threshold to be reached faster </u>by increasing the rate of depolarization and thus causes heart arrhythmia.
Therefore, <u>Norepinephrine acts on the heart by </u><u>causing threshold to be reached faster.</u>
