The Heart and Circulation of Blood In this research paper‚ I will be analyzing the process of blood circulation within the human body. I will be focusing on the pulmonary circuit and the systemic circuit‚ as well as the relationship with the hepatic portal system. The combination of these systems allows the body to function properly and maintain unconscious homeostasis. I will also be talking about the effects that fitness and diet have on these processes. The pulmonary circuit passes already-used

Exercise on Blood Pressure Katie Law-Balding June 28‚ 2010 Abstract The purpose of this experiment was to see what effect 30 seconds of physical activity would have on a subject’s blood pressure. In this case‚ physical activity is defined as stair running at a moderate pace for 30 seconds. Standing blood pressure was measured before and after physical activity for comparison purposes. Three trials were completed and initial blood pressure was 94/75 mmHg‚ 125/92 mmHg‚ and 106/92 mmHg. Blood pressure
Free Blood pressure Hypertension
Blood pressure is defined as the force of flow of blood inside the blood vessels. This measure is reported as two numbers such as 130/180 mm Hg. The first number is called systolic pressure and measures the push of the blood through the vessels as the heart beats. The second number called the diastolic pressure and measures pressure in between heartbeats or when the blood vessels relax. High blood pressure is one of the most commonly associated medical conditions with diabetes. US statistics reveal

Hypertension is high blood pressure. This is a condition that has taken place from your external environment. For example‚ you may be under stress at your job or school. The stress can be very demanding and causes several things to happen to your body. The blood is pressured against the wall of your blood vessels causing your heart to beat faster and harder. This causes an increase in your pressure and now your normal functioning of your blood pressure is now disturbed or out of balance. The organ

In this folio task‚ the impact of drug absorption and blood stream concentration‚ on the human body‚ will be observed. The rate of absorption and clearance of the drug‚ relies on many factors. The drugs blood stream concentration‚ time of administration‚ absorption rate‚ clearance rate and the effect of certain parameters‚ will be calculated. This can be completed through using a surge function‚ calculus (derivatives) and straight line graphs (). Graphing technology on the graphics calculator

The Effect of Caffeine on Heart Rate Caffeine is made by plants as a way of getting rid of insects. Cocoa is produced in South America‚ coffee in Africa and tea is produced in Asia have all been used for a very long time to give us a little rush in order to keep us going. Now caffeine is also used as a flavour enhancer in cola and other soft drinks also it has medicinal uses in aspirin preparations and is found in weight-loss drugs and as a stimulant in normal people in everyday to

Medical Problem: High Blood Pressure (Hypertension) Patient: Megan Crozier 1. Define the health issue (the impact on the body) Hypertension is sustained elevation of resting systolic BP (≥ 140 mm Hg)‚ diastolic BP (≥ 90 mm Hg)‚ or both. High blood pressure is a common condition in which the force of the blood against your artery walls is high enough that it may eventually cause health problems‚ such as heart disease. Blood pressure is determined by the amount of blood your heart pumps and the

Literature Review The human heart is a very complicated organ‚ with the main purpose to pump life sustaining blood throughout the human body. It also supplies oxygen and nutrients to all areas and clears harmful waste from the body. The heart is made up of cardiac muscle which beats on its own. According to the article ‘heart ‘which was written by The National Geographic the heart will slow down or speed up depending on how the body is being used. This is done by nerve signals which are being

which blood vessel diameter can be modified? Detection of changes in blood pressure (leading to resultant changes in blood vessel diameter): Baroreceptors at the carotid sinus (the bifurcation of internal and external carotid arteries in the neck) and the aortic arch detect changes in blood pressure. These non-encapsulated nerve endings‚ located in the adventitial layer of arteries‚ are technically mechanoreceptors; they respond to arterial distension occurring due to a change in blood pressure

The Effect of Exercise on Heart Rate The aim of this investigation is to find out how different types of exercise can affect my heart rate. To measure and record my heart rate‚ I am going to undergo an experimental test. I am going to do 3 different types of exercise: walking‚ light jog and lastly hard running. First‚ I will draw out a table to record my results‚ and then I will measure my resting heart rate for one minute. To make the experiment as accurate as possible‚ I will
