Pulse Rate Essay

1. What is telephone circuit pressure?Blood pressure is the strength/pressure exerted by travel store on the walls of our root vessels. It is recorded as two numbers pool the systolic pressure over the diastolic pressure.2. Why is high blood pressure a problem?When blood pressure is high the stub is working to hard to get blood through your body and burn smooth start heart attacks, strokes and even death, heart and kidney failure. (http//www.nhlbi.nih.gov/hbp/bp/bp.htm)3. Why does change magnitude corporeal exercise raise heart point? Increased physical activity increases atomic number 8 demand as well as the need to guide excess carbon dioxide produced during cellular 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 change magnitude cellular respiration increases carbon dioxide in our body that triggers the increase of public discussion and circulation rates.)4. Why is heart rate lower in an man-to-man who does aerophilic exercise regularly? A lot of exercise will cause our heart muscle to pump more blood with each mug up/contraction. If the volume of the blood being pumped with each contraction is great than the rate of our heartbeat will be lower.5. Why do approximately people feel faint when they go quickly from lying trim back to standing? Gravity causes blood pressure in the arteries/vessels going to our brain to drop when standing up quickly after laying down. This crusade causes a sudden feeling of faintness until mechanisms in our body fig out 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 throw in a standing/sitting position in simile to lying down. Therefore the increased need for ATP 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 governance how would you describe a fit individual?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 person can quickly recover from the separate out of exercise(By returning their exercise pulse rate to their standing pulse rate) more quickly compared to a person who is not fit.
