Waking
As the person has just woken the heart rate will be at rest, between 60/80 beats per minute (bpm). Anticipatory Response will take place, neurotransmitters known as adrenaline and non adrenaline are released, and the heart rate will start to increase also. These are two separate but related hormones secreted by the medulla of the adrenal glands. They are also produced at the ends of sympathetic nerve fibers, where they serve as chemical mediators for conveying the nerve impulses to organs. Both hormones increase the rate and force of contraction of the heart, increasing the output of blood from the heart and increasing the blood pressure. The hormones also have important metabolic actions
The person energy level is low before breakfast. The artery will act as a transporter carrying blood away from the heart throughout the body under high pressure from the ventricles of the heart, which conduct the oxygenated blood (except in the case of the pulmonary artery, carrying de-oxinated blood) to the various tissues and organs.(livestrong.com). , Glucose in the blood comes from food consumed each day for energy, it is stored in the liver as an energy source. Glucose is transferred around the body by the blood and blood vessels (artery, veins and capillary). Epinephrine stimulates the breakdown of glycogen to glucose in the liver, which results in the raising of the level of blood sugar which the person will use as energy. (Britannica.com)
