Cardiovascular system has three main functions: Transport of nutrients, oxygen and hormones to cells throughout our body and removal of metabolic wastes such as (carbon dioxide and nitrogenous wastes). Protections of the human body by while blood cells, antibodies and complement proteins that circulate in the blood and defend our body against foreign microbes and toxic. Clotting mechanisms are also present that protect the human body from blood loss after injuries. Regulation of body temperature, fluid pH and water content of
The air which we breathe in which is kept in the lungs, is the transferred into blood. The blood then goes around the heart, which then pumps oxygenated blood from lungs back into the body. The 2 systems also work together in order to get rid of carbon dioxide which is there as a metabolic waste product. D1
The cardiac cycle is vital in all organisms with a heart, to pump blood round the body. There are phases of the cardiac cycle; systole (contraction) and diastole (relaxation). The heart consists of 4 chambers, 2 being the atria at the top of the heart and the other 2 being the ventricles at the bottom of the heart. Systole occurs separately in the atria and ventricles and diastole occurs simultaneously in all 4 chambers. The cardiac cycle is controlled by electrical waves that spread throughout the heart.
This paper aims to describe the pathophysiology of atrial fibrillation and the rationale behind the information included in the patient education tool. Atrial Fibrillation: A Patient Education Guide The heart is a muscle that contains four chambers; the right atrium, left atrium, right ventricle, and left ventricle. Each of these chambers has a purpose. The right ventricle pumps blood to the lungs and the left ventricle pumps blood to the rest of the body. The right atrium receives deoxygenated blood via the superior and inferior vena cava.
http://www.healthline.com/human-body-maps/tricuspid-valve The Pulmonic Valve: This valve is found between the right ventricle and the lungs. As the deoxygenated blood continues on its journey through the heart from the right ventricle, it makes its exit by way of the pulmonic valve. This structure is a one-way valve with prevents the flow of blood back into the right ventricle once it leaves the heart. http://www.healthline.com/human-body-maps/pulmonary-valve The mitral valve: This valve is located between the left atrium and the left ventricle. As the now oxygenated blood flows back through the left atrium, it does so under increased pressure.
Anatomy & Physiology Chapter 19: Vascular * Contrast the structure and function of the various types of blood vessels * Explain how the venous blood is returned to the heart * Explain blood pressure and pulse * Discuss the factors that affect blood pressure * Contrast the clinical significance of systolic, diastolic, and pulse pressure * Discuss the mechanism of capillary exchange * Describe blood flow through systemic and pulmonary circuits. Identify the principal arteries and veins of the systemic, pulmonary, and hepatic portal circulations * Describe unique aspects of fetal circulation * Explain the effects of exercise on the cardiovascular system * Describe significant cardiovascular diseases
This occurs because of the increased need for oxygen by the thickened ventricle and because of reduced blood flow to the coronary arteries. o irregular heartbeat which you may feel as palpitations. • If the narrowing is severe the left ventricle may not function properly and you can develop heart failure. This causes shortness of breath, tiredness, and fluid retention in various tissues of the body. See separate leaflet called 'Heart Failure'.
Cardiomyopathy and Congestive Heart Failure: Case Study #2 GCU Pathophysiology and Nursing Management of Client's Health NRS 410 V Cardiomyopathy and Congestive Heart Failure The main function of the heart is to pump blood to meet the needs of the body. Heart failure occurs when the heart doesn’t have the ability to pump enough blood to the different parts of the body. This can occur if there is any defect in the heart muscles or if it becomes weaker due to some other factors. When this happens the kidney receives less blood to filter. The extra fluids build up in the legs, lungs, liver and around the eyes.
When your blood gets to your lungs, the oxygen from your lungs gets put into your bloodstream. Then it goes back to the heart, with the oxygen-enriched blood being delivered to all parts of your
