The heart pumps blood round a complex route of many vessels. This brings about a resistance and generates pressures within the system. This pressure in the blood is high when the left ventricle is contracting and working and it reduces when it is at rest. The pressure is high also when blood is pumped into the artery to be distributed all over the body. Blood
TASK 3.1 Write a report comparing and contrasting the structure and function of the three types of blood vessels. The Structure and Functions of Blood Vessels ARTERIES The walls of arteries contain smooth muscle fibre that contract and relax under the instructions of the sympathetic nervous system. The functions of the arteries are: transport blood away from the heart and transport oxygenated blood only. Arteries have four different parts, which are; lumen, endothelium, smooth muscle and connective tissue. LUMEN=the lumen of arteries is relatively narrow to maintain high blood pressure.
Three activities are performed that best illustrate how the cardiovascular system works. The activities have to do with listening for heart sounds, and feeling for pulses in peripheral locations on the body, such as wrist or arm. The reason heart rate is determined is because the quality of the pulse, the regularity and strength, is usually an indicator of cardiovascular function. Blood pressure is also measured indirectly, such as with a medical instrument. The arterial blood pressure is taken because it determines the heart’s condition the health of the blood vessels.
Why is this so? It is because a higher amount of force is needed to be exerted to move the water through the small pipe as compared to the larger pipe. The more water to be transported, the higher the pressure is needed. So in the arteries of the human being, if its pathway is blocked by fatty deposits, the walls becomes smaller and the heart has to pump a higher amount of pressure to get the blood flowing through, resulting in hypertension. In order to check if a patient is suffering from hypertension or abnormal levels of blood pressure, there are four indirect and non-invasive methods to assess the patient.
The high prevalence of hypertension worldwide has contributed to the present pandemic of cardiovascular disease. World Health Organization South East Asia Region (2013) found that nearly 1.5 million people die due to hypertension making it a leading risk factor for mortality. Hypertension is a term used to describe high blood pressure. Flow of blood is based on the beat of which the heart pumps blood. The pressure of the heart does not stay at the same level at all times.
My mode is Duo Positive Airway Pressure on the Hamilton G5. It is pressure control, a set inspiratory pressure is set to be proportional to patient inspiratory pressure. The breath sequence is intermittent mandatory ventilation (IMV). Ventilatory support is between mandatory and spontaneous breaths. The rate setting directly affects the number of mandatory breaths and the level of ventilatory support.
The heart is an organ of muscles. It’s necessary to pump blood throughout the body. The heart has four chambers: two atria (left and right) and two ventricles (left and right). The two atria chambers are located at the top of the heart; whereas, the two ventricles are located at the bottom of the heart. The chambers help blood flow smoothly through the heart.
Well, with no or little clotting factor, Hemophilia victims tend to bruise easily, have excessive bleeding, spontaneous bleeding, and bleed in there joints. This may seem terrible, but in reality, we only see this disease on a basic level. We cant see the troubles it brings us. Currently, the treatment for hemophilia for a year is about 40,000 american dollars, but since these victims would need special care and special facilities, it would cost around
Introduction This essay will reflect on my personal experience, skills, and knowledge gained from my studies and practice of undertaking blood pressure (Bp) whilst completing my professional placement. Bp may be defined as a force of blood against vessel walls in the body, consisting of systolic and diastolic pressure measured in millimeters of mercury. (Waugh and Grant, 2016) Systolic pressure occurs when the hearts left ventricle contracts and forces blood into the aorta causing a heightened atrial pressure, while diastolic pressure refers to complete cardiac diastole, this is when the aortic valve closes and pressure is at its lowest between beats, blood moves into smaller corresponding vessels and the heart rests. (Marieb and Hoehn, 2016) In my clinical setting, it was expected that a level of proffesional protocol is carried out for a correct, and safe arterial reading while maintaining a hygienic and aseptic approach that is safe, and reduces the risk of detrimental harm to myself as a healthcare professional and to the patient in my care. Bp is read from patients as a matter of determining illness by monitoring what is known as a NEWS score, presenting a validating number to recognise the level of health of an individual.
The signs and symptoms of COPD include shortness of breath, chronic cough, fatigue and having bluish lips and nail beds (American Lung Association, 2014). The second vital human body system is cardiovascular system (CVS). CVS plays an integral role in enhancing and facilitating the proper function of heart in order to allow the body to function as a whole. CVS comprises of two components namely heart and blood vessels. Heart is a four-chambered muscular pumping organ that divides into atriums and ventricles that are separated by valves to prevent backflow of blood among the compartments (Smeltzer, Bare, Hinkle, & Cheever, 2010).
