PHYSIOLOGY REPORT 2IntroductionBaroreceptors are receptors found on the walls of the blood vessels and communicates to the brain if the blood pressure is very high/low such that they can change the blood flow. On the other hand, the chemoreceptors are situated in different areas. The carotid bodies in the carotid arteries that start from the neck up to the brain and the aortic bodies in the aortic arc near the heart. When having a problem characterized by hypotension and high pulse rate can be of great concern prompting you to visit a doctor the soonest time possible. Pulse rate is the number of heart beats per minute while blood pressure is the pressure of the blood that circulates on the blood vessel walls (Cheng et al. 2014). There are pathological conditions and real-life activities that cause a change in the normal blood pressure and pulse rate. The rationale of this paper is to write a report about physiology and metabolism. A table of normal value below will be used for reference throughout the report.Systolic pressure121.0mmHgDiastolic pressure75.1mmHgRight atrial pressure1.7mmHgMean capillary pressure12.7mmHgMean rate69.7/minStroke volume71.5mlCardiac output5.0l/minTotal arterial resistance16.0mmHg.l/minCardial contractility1.3l/min/mmHgExercise 1a)When the pulse rate, the blood pressure and the Arterial Resistance (AR) is raised.

PHYSIOLOGY REPORT 3From the Mac Man computer simulation recording sheet, a rise in the resistance pressure would result in hypertension or HBP (due to the stage I hypertension of the diastolic pressure and hypertension of the systolic pressure) and low heart rate. A prolonged low heart rate can lead to afrequent cardiac arrest, fainting even death because of the failure of the heart tissues to supply adequate blood to the rest of the body (Davies 2013). Scientifically, what happens is that the walls of the heart, as well as the blood vessel, broadens as a result of the high pressure thus leads to hardening of the arteries of the heart. Such conditions can cause stroke, organ failure, or heart attack.b)Factors that increase blood pressureThere is a host of aspects that may lead to a high blood pressure such as being obese or having a body mass index of 30kg/m or more. When the body weight of a person increases, the blood pressure also increases (Gilmore et al. 2014). Other factors include sodium or salt sensitivity (this is where some individuals have high sensitivity to sodium chloride which makes their bloodpressure to rise if they use it). Drinking too much of alcohol, birth control pills especially for the women, lack of exercise or exercise or physical inactivity (where some people live a sedentary life that can lead to being obese and high blood pressure). Scientifically, medications such as dietpills, and stimulants. Have been known to raise high blood pressure when used. According to Jeon and Osborne (2012), there are non-changing factors that can lead to high blood pressure. They include age where aged people are likely to have HBP due to hardening of the arteries, racewhere African Americans develop hypertension more often compared to Caucasians, heredity or
