Abstract: This research will be an overview about what are the pressure related dangers of scuba diving, how do these dangers happen, how to prevent those dangers and the identification of their symptoms. Introduction: A form of underwater diving with the use of breathing apparatus to breathe underwater is Scuba Diving. Great freedom of movement and longer underwater endurance can be felt for diving with their own or personal source of breathing gas which contains compressed air rather than…

ingenious experiments called “Opinion and Social Pressure”. Asch discovered by doing these experiments that individuals can be persuaded by a group of people to deny your own sense. Over the years Asch got the information to provide a powerful explanation on how people will forget their own sense and judgment to their peers. In “Opinion and Social Pressure” Asch did many experiments to figure out what the effect would be on if a group pressures an individual throughout a series of tests. Asch…

D. PULSE PRESSURE INTRODUCTION The pulse pressure is the difference between the systolic and diastolic pressure. The systolic or top pressure is defined as the amount of pressure exerted on the blood vessels when the ventricle is contract (systole). The pressure is due to the force produced as the blood is ejected contacted with the blood vessel’s wall. On the other hand, the diastolic or bottom pressure is defined as the amount of pressure of the blood vessels when the heart is at rest…

evaporates readily at room temperature or a liquid that has a measurable vapor pressure. Vapor pressure is the equilibrium pressure resulting in the evaporation of a liquid in a closed container.1 It is important to know the vapor pressure of a volatile liquid because the higher the vapor pressure, the faster the liquid evaporates.2 So…

Blood Pressure: Systolic and Diastolic Abstract Blood pressure is when your heart beats and so it pumps blood back up to your body for it to have energy and oxygen. However, as your blood pushes it creates strength, so this creates blood pressure. Pulse is to see the rate of your heart going beats per minute. In this experiment, we gather data to see if the level of physical activity could affect the result of the systolic and diastolic measures in blood pressure and if the pulse would also be…

Introduction: Blood pressure is controlled by the autonomic nervous system and is the pressure of the circulating blood being exerted upon the arterial walls of the blood vessels. Blood pressure is determined by ones cardiac output, blood volume, and peripheral resistance. Blood pressure is expressed by a systolic pressure and diastolic pressure and is measured in millimeters of mercury (mmHg). Systolic pressure is the maximum pressure during ventricular contraction of the left ventricle while…

with the pressure in your head and that marijuana is the alternative drug that can make it better. I immediately think about the movie “How High” and see the little old lady sitting on her bed with a pipe saying that it helps with glaucoma too. But is any of this true? Yes and no. Glaucoma does not affect the pressure in your head known as intracranial pressure or ICP. What it does affect is the pressure that is put onto the optic nerve, this type of pressure is call intraocular pressure or IOP.…

Blood pressure is the pressure applied by blood on the walls of blood vessels, it is controlled by a negative feedback system where heart rate and blood volume need to be altered in order to control the pressure. Local negative feedback systems and heart rate is regulated but the cardiovascular centre which also in turn controls neural and hormonal mechanisms. Neurons regulate heart rate and contractility and some neurons inhibit, stimulate or control heart rate by causing constriction which…

Important Facts about Blood Pressure The heart is the most important organ in the body as it helps to pump blood to other parts of the body. Blood pressure can be described as the force that the blood exerts on the arteries as it moves throughout the body. Generally, blood comes out of the heart at a higher pressure and later reduces as it is circulated through the arteries. High blood pressure is one of the leading silent killer diseases in the world today. This is because it is not easy to…

Blood Pressure Blood pressure , as a physiological variable of humans, is a hydrostatic pressure, utilized by blood on the walls of blood vessels.(Tortora and Derrickson 2011). It is caused by the contraction of the ventricles and the amount of blood in the whole cardiovascular system. The mean blood pressure (the average pressure in the cardiac cycle) is coordinated in order to provide adequate blood transfer to the tissues.(Saladin,2001). The decrease of blood pressure is followed by an…
