returning from the lungs and to act a pump to transport blood to other areas of the heart. The walls of the left atrium are slightly thicker than the walls of the right atrium. Oxygen-rich blood from the lungs enters the left atrium through the pulmonary vein. The blood is then pumped into the left ventricle chamber of the heart through the mitral valve. From there, the blood is ready to be pumped into the body to deliver oxygen throughout Tricuspid valve: The valve between the right atrium and the

to collect blood samples. A central line is inserted under the skin away from the vein, and it comes out from a subcutaneous route. A cuff is placed around the tunneled part of the line securing placement and helping to prevent infection to the insertion site. Central lines are inserted into large veins in the central circulation (Caring, 2015). The catheter is threaded into the internal or external jugular vein; it can also be threaded into the lower third of the vena cava leading to the superior

Jacie Fields English Comp 1 Research Essay P.A.P.V.R Partial Anomalous Pulmonary Venus Return also known as (PAPVR) is when the four pulmonary veins return oxygen-rich blood from the lungs back to the right atrium. PAPVR is more commonly diagnosed among children. This condition causes oxygen-rich blood to flow back into the lungs instead of forward to the rest of the body. PAPVR is a rare congenital heart defect that can either be total (TAPVR) or partial (PAPVR). If it is not diagnosed and treated

the heart for the blood to be refreshed with oxygen and nutrients. Veins are the blood vessels that carry the blood, rich in waste content and low in oxygen content back to the heart (http://www.fairview.org/fv/groups/internet/documents/web_content/pdf_pad_screening.pdf, ). The main function of veins is to carry blood back to the heart. Veins are not muscular and are less flexible when compared to arteries (PVD). Unlike arteries, veins contains one way valves (unidirectional valves) that prevent the

A central venous catheter is known as a central line or a CVC. A CVC is a thin flexible catheter that is inserted into a large vein near the heart in either the arm or the chest. (Web MD, 2016) This central line is used to provide medication, fluids, nutrients, or blood products over a long period of time. This is generally used for patients who have chemotherapy, frequent blood draws, need additional nutritional support, or have kidney failure. (ATS, 2015) There are several considerations to keep

The cardiovascular system can be split into three different parts: the blood, the heart, and the blood vessels. They all work within the cardiovascular system in their own individual ways and each has their own unique characteristics and functions within the system. Blood is generally composed of 55% Plasma and 45% Formed Elements (Castillo, 2018). Plasma is the liquid part of the blood that is 90% water and 10% wastes, gases, hormones, and proteins, while the formed elements are erythrocytes or

parts of the body (V, pg. 35), where it makes its way into the veins and porosities of the flesh, and then flows by the veins from the circumference on every side to the centre (XI, pg. 60), from the lesser to the greater veins (XIII, pg. 69), and is by them finally discharged into the vena cava and right auricle of the heart (XIII, pg. 72), and this in such a quantity or in such a flux and reflux thither by the arteries, thither by the veins, as cannot possibly be supplied by the ingesta, and is much

developing a new pulse photometry techniques. The mock circulatory system consists of a compliance chamber that simulated aortal elasticity a clamp to simulate peripheral vessel resistance and a reservoir chamber to simulate reserved blood in the veins. Artificial heart valves are used both at the inlet and outlet of the pump to avoid regurgitation making it a unidirectional flow. Pump unit consists of an elastic silicone tube inside an acrylic pipe and saline is filled in between them. The actuated

superficial veins used in performing venipunctures. State the order of the draw. Venipuncture is a process done by a phlebotomist to either collect blood from the patient or to administer therapy via an IV. The arms, hands and feet are all accessible for venipuncture procedure. The most common location most of us get blood drawn from is where your elbow bends also known as the antecubital fossa. This location is where you will be able to locate the Median Cubital Vein. The median cubital vein is the superficial

will do immediately to counteract the change in blood pressure and pooling of blood in the veins. (1) Your heart rate increases and pumps a greater volume of blood. This will increase blood pressure (BP) so that you avoid fainting. (2) The valves in your veins maintain a one-way flow of blood to the heart which aids venous return of blood to the heart. (3) Your skeletal muscles contract and help compress the veins providing resistance to pooling of blood. These muscle twitches act much like a flight
