Aortic valve

into the pulmonary artery. In the lungs the blood gets oxygenated and returns to the left atrium through the pulmonary veins. It passes through the left AV into the left ventricle and when the left ventricle contracts blood is forced through the aortic SL, into the aorta and distributed to the body (“The Heart and Heart…

Physiology Murmurs are the product of intense blood flow across inflexible, calcified valves; faulty valves that permit reverse blood flow (regurgitation); faulty (deviant openings) in the septum, aorta, or pulmonary artery; or abnormally high velocity of blood flow through a normal structure. Supposedly blood generally flows soundlessly through the heart; yet, these conditions can generate tumultuous blood flow resulting in auscultation of swooshing or gusty sound over the precordium (Weber &…

blood into the blood vessels and keeps it flowing through the body (Rizzo, 2016). The left ventricle is a cavity that has thick muscular walls that contains the papillary muscles as well as the chordae tendinae that attaches the atrio-ventricular valve leaflets to the papillary muscles (Leeson, Augustine, Mitchell & Becher, 2012). The left ventricle is responsible for pumping blood through the entire body, while the right ventricle only has to pump blood to the nearby lungs and back.…

“The heart valves work the same way as one-way valves in the plumbing of your home, preventing blood from flowing in the wrong direction” (ClevelandClinic). The tricuspid valve is the first one that the blood comes across as it arrives the heart. It stands between the right atrium and the right ventricle. The valve only permits the blood to flow from the atrium to the ventricle (Healthline). The pulmonary valve is at the opening from the right ventricle in the…

When a thrill is prominent and widespread, application of the entire palm of the hand is helpful in sensing the direction of radiation. An aortic stenotic thrill radiates upward and to the right, and a pulmonary stenotic thrill radiates upward and to the left. If a thrill is localized, relatively firm application of a fingertip usually suffices for detection.” (Perloff). The distal metacarpals…

Characteristic clinical findings involved with MFS include “ocular, skeletal, and cardiovascular systems.” Major features of diagnosis are defined as “lens dislocation, aortic dilation or dissention, dural ectasia, and four of the eight skeletal features” (NIH. National Human Genome Research Institute). Lens dislocation is seen in six out of ten people with MFS due to the connective tissue weakening. Symptoms of lens dislocation…

the right atrium contracts and pumps its contents into the right ventricle through the tricuspid valve. Once the right atrium is drained completely, the tricuspid valve will close to prevent blood from flowing back into the right atrium. Next, the right ventricle contracts, causing the pulmonary valve to open and forcing blood into the pulmonary artery. Once the blood is emptied, the pulmonary valve will close to prevent backflow. The deoxygenated blood will travel to the lungs through the…

the breastbone. It has two major coronary arteries, electrical impulses, four chambers, and four valves to help the blood flow one way. Deoxygenated blood enters the right atrium from the superior and inferior vena cava. When the right atrium contract the blood flows through the tricuspid valve and into the right ventricle. When the right ventricle contracts the blood passes the pulmonary semilunar valve, into the pulmonary artery, and the blood is going to the lungs. The blood goes through a…

from mixing there is a structure called an interventricular septum. The septum separates the cardiac chambers; right and left atria and the right and left ventricles. There are four valves, which regulate backflow to the chambers. There are two types of valves, which are the atrioventricular valves and the semilunar valves. The atrioventricular…

Rheumatic heart disease is when the heart is damaged. It’s often damage to the valves of the heart. Rheumatic heart disease is a result of having rheumatic fever. It’s commonly seen in children in many developing countries around the world. To begin with, Rheumatic fever causes a person to have rheumatic heart disease. Rheumatic fever affects the connective tissues of the body, mostly the connective tissues of the heart, brain and the joints of the body. Rheumatic fever is associated with having…
