Pulse Rate Essay

1. What is stock certificate stuff?Blood pressure is the strength/pressure exerted by circulating slant on the walls of our blood vessels. It is recorded as two numbers the systolic pressure over the diastolic pressure.2. wherefore is mellow blood pressure a problem?When blood pressure is high the heart is working to expectant to get blood through your system and can cause heart attacks, strokes and even death, heart and kidney failure. (http//www.nhlbi.nih.gov/hbp/bp/bp.htm)3. Why does increased physical activity raise heart rate? Increased physical activity increases oxygen demand as well as the need to remove excess nose candy dioxide produced during cellular respiration. In order to meet oxygen needs our heart rate increases along with other respirations to supply our body with the necessary oxygen. (Muscles require more oxygen for cellular respiration and increased cellular respiration increases carbon dioxide in our body that triggers the increase of alive and circul ation rates.)4. Why is heart rate lower in an idiosyncratic who does aerobic exercise regularly? A lot of exercise will cause our heart musculus to pump more blood with all(prenominal) beat/contraction. If the volume of the blood being pumped with each contraction is greater than the rate of our heartbeat will be lower.5. Why do some batch feel faint when they go quickly from lie down to standing? Gravity causes blood pressure in the arteries/vessels going to our brain to drop when standing up quickly after laying down. This communicate causes a sudden feeling of faintness until mechanisms in our body elevate our blood pressure in the vessels to normal again.6. How and why does heart rate change with body position?Heart rate increases from lying down to standing up because more energy is required for our body to maintain in a standing/sitting position in comparison to lying down. Therefore the increased need for adenosine triphosphate increases cellular respiration that causes an increase need for oxygen and carbon dioxide levels in our body that triggers increased breathing so our heart rate increases as well.7. From your study of the circulator system how would you describe a fit soul?A fit individual has an ability to contain a lot of oxygen by having an expeditious respiration and circulatory system. When having these efficient systems their heart is allowed to pump more blood with each beat and the individual can quickly recover from the stress of exercise(By returning their exercise round rate to their standing pulse rate) more quickly compared to a person who is not fit.
