Blood is moved from the heart to the body by arteries. Blood pressure is the force of the blood pushing against the walls of the arteries. With each heartbeat‚ blood is pumped into the arteries. Systolic pressure is determined when the heart is contracting which causes increased pressure in the arteries. Diastolic Blood pressure is the remaining pressure in the arteries when the ventricles of the heart is relaxed allowing the heart to fill with blood. Blood pressure is influenced by cardiac output

Biology 511 Article Summary Vital Signs By H. Lee Kagan Vital Signs by an internist H. Lee Kagan is an account of a healthy-looking woman without warning (no crying‚ no clutching of chest)‚ suddenly collapsed onto the floor during check in at a clinic. A doctor acts swiftly to diagnose the potential fatal conditions the patient might be experiencing. First‚ the doctor checked the three most important things: airway‚ breathing‚ and circulation and concluded that the patient has no cardiac or respiratory

Exchange Rate Notes Class Notes Exchange rate can be expressed in two ways‚ for example: £1 = 1.52 CHF 1 CHF = £0.66 Foreign Exchange (Forex) Market Many currencies float freely on the free market. However‚ this is a relatively new phenomenon. After the war‚ major currencies were pegged to each other under the Bretton woods agreement. They were backed up by gold reserves to keep them at this level. Prior to the war they were often pegged to the price of Gold. Prior to the Euro (1990s)

Horne Date: 9-25-2012 Topic: How to Check Your Blood Pressure Type: Demonstration Speech Mode: Memorized Introduction: I asked several questions to get the attention of my audience. This speech was a chance for me to share steps and experience on checking your blood pressure only takes 30 seconds. The steps were clearly stated‚ first choose the right equipment‚ second‚ stabled patient and third the right size blood pressure cuff. Blood pressure issues can strike at any age. The chaos‚ confusion

Purpose Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries‚ even when the surrounding temperature varies and is of higher or lower temperature than what is normal. The purpose of thermoregulation is to balance thermal inputs and thermal losses in the body so as to maintain a relatively constant core temperature of approximately 36.7 degrees celsius. If this was unable to take place the body may not be able to functions properly and it could result in hypothermia

Hypertension‚ also known as high blood pressure‚ is a chronic condition in which blood pressure is elevated. “Blood pressure is the force of blood pushing against the walls of arteries as it flows through them. Arteries are the blood vessels that carry oxygenated blood from the heart to the body ’s tissues. As blood flows through arteries it pushes against the inside of the artery walls. The more pressure the blood exerts on the artery walls‚ the higher the blood pressure will be. T he size of small

added more literates in rural India from 58.7% in 2001 to 68.91% in 2011‚ the job market hasn’t kept pace with the growing demands of job seekers from villages. The bigger cause for concern according to the labour ministry data is: the unemployment rate among rural educated youths is higher as compared to their urban counterparts. It stands at 13.9% for rural areas against 7.6% in urban areas. The ministry data‚ released on July 18 this year confirms worst fears of expanding education sector not

AIMS The aim of this experiment was to investigate the effect of temperature rise on the rate of transpiration of a plant (hibiscus) by measuring the plant’s water uptake in a period of time. HYPOTHESIS Transpiration is the process by which plants loses water to the atmosphere from their leaves. Water in the plant is lost to the atmosphere by evaporation. Evaporation of water can occur at any temperature. In the presence of sunlight‚ water in the plants evaporates into the intercellular air

Change in respiratory rate during exercise Aim: To record and investigate how the breathing rate varies for the duration of light and heavy exercise. Introduction: When an individual exercises‚ the muscles being used needs extra energy from oxygen. The lungs pump oxygen to the heart‚ and then the heart pumps the oxygenated blood through the blood to the particular muscle that is working. The human body has a series of organs working together‚ which is named the respiration system. The organs involved
