Circulatory system

Purpose: The purpose of this memorandum is to present an analysis of the person(s) who would read this report. This report was created as one of the projects for a Writing for Technical Professional class. The goal of this project was to analyze the success of a medical innovation. My chosen topic was Focused Ultra Sound that enhance the drug delivery for treatment of CNS diseases. Audience Description: While writing this technical report, I imagined 2 types of people who would read it. The…

Jackson Newman March 4, 2016 Advanced English-6th Hour Mrs. Meadows Muscular System The muscular system is one of the most vital system in the body because without it the human body would not be able to move or function properly. The main function of the human body is movement. When the regular body temperature drops, the body starts to shiver to maintain homeostasis. Muscle groups begin to shake, trying to create heat/warmth by expending energy. This also means that a large…

This practical allowed for a better understanding of the changes in cardiovascular (heart rate and blood pressure) and respiratory (ventilation and oxygen consumption) during submaximal exercise, in that they all increase in response to increasing watt power during submaximal exercise. The results were as expected with no surprising outcomes. Figure 1 showed that ventilation increased as watt power increased, going from 25 l/min at 60 watt levels to 49 l/min at 150 watt levels. Ventilation…

smooth outer membrane is called the epicardium and its inner lining is called the endocardium. The heart muscle like any other organ or tissue in your body needs oxygen-rich blood and nutrients to function properly. A system called the Coronary Circulation is part of its own Vascular System, which is when the blood is supplied to the heart through circulation of blood in the blood vessels. The main blood supplier to the body…

The renal artery supplies blood to the kidney. The human kidneys receive approximately 25% of the blood pumped. Blood enters the capillaries of the nephron through the afferent arteriole. It then flows through the glomerulus and into the efferent arteriole. The varying sizes of these arterioles help to create the hydrostatic pressure and to maintain consistency of glomerular capillary pressure and renal blood flow within the glomerulus Before returning to the renal vein, blood from the…

The arteries are blood vessels that deliver oxygen and nutrients to all organs in the body during the heart pulses. During the blood circulation a pressure is exerted on the walls of the blood vessels or arteries. The case where the ability of such walls to expand or contract in response to blood pressure changes is called Arterial Stiffness (AS). Arteries need to be flexible to expand when oxygen is needed by muscles and heart, and stiffening of the arteries place an extra load on heart which…

The cardiovascular system The cardiovascular system consists of the heart, blood vessels and approximately the 5 litres of the blood that the blood vessels transport. The cardiovascular system is powered by the body’s hardest working organ. The cardiovascular system is responsible for transporting nutrients and removing gaseous waste from your body. The main structures of this system is the heart the blood vessels and blood. Delivery of oxygen and nutrients The pulmonary circuit carries blood…

We all know that the main functions of the blood are the transport of respiratory gases, digested food or nutrients, waste products, hormones, enzymes and ions from one body part to another, it protects a body against diseases and regulates body temperature. In other words, blood is the essence of life. A body cannot survive without a sufficient amount of blood. Unfortunately, there are people who don’t have the same chances as we do. Let us take the United States as example. Every two…

exercise changes would occur in our cardiovascular system. When performing exercise, your muscles would need sufficient amount of oxygen and nutrients so that you can perform well. Also, the carbon dioxide produced should be released from the body. It is the main role of the heart to pump harder and faster when exercising so that oxygen is taken in and carbon dioxide is released as a by-product. There are many acute changes that occur in this system before, during and after exercise. Heart…

used psychoactive drugs, is a central nervous system stimulant that induces the sense of alertness and awareness. Inspired by the previous research on how the caffeine affects the cardiovascular system, we wanted to test the effect of different concentrations of caffeine on the heart. We used ECG stimulator on LabScribe 2 software to monitor the heart rate. We used frogs as a test subject, since both frogs and humans have a closed cardiovascular system, therefore the effect on the frog’s heart…
