Pulmonary artery

composed of the heart and the blood vessels. The main function of the cardiovascular system is to pump blood around the body. The cardiovascular System is divided into two parts, the systematic circuit and the pulmonary circuit. The systematic circuit contains oxygenated blood and the pulmonary blood contains deoxygenated blood. In order to prevent oxygenated and deoxygenated blood from mixing there is a structure called an interventricular septum. The septum separates the cardiac chambers;…

Describe the structure and function of the cardiovascular system Blood vessels Arteries, veins and capillaries takes blood and nutrition to the muscles and back from the heart. Arteries take the blood that has O2 in it away from the heart under high pressure with a small diameter and it has thick muscular walls, and veins take the blood back to the heart under low pressure it has a medium thickness to it and a large diameter because it has valves to stop the blood flowing backwards.…

Fetal circulation differs greatly from that of a newborn heart. Although, outwardly appearances may seem similar. By taking an internal look we may be able to distinguish four adaptations that fetal hearts undergo while in utero. First, we must understand that the fetus receives all blood and nutrients from the parental placenta. The fetus receives this blood from the placenta through the umbilical vein. This is the first adaptation that we see in the fetal cardiovascular circulatory system.…

cardiovascular system. The heart has four main parts: the left ventricle,the right ventricle, the left atrium, and the right atrium. A wall of muscle called the septum separates them. Oxygen-rich blood from the lungs goes to the left atrium by the pulmonary vein. The left atrium then pumps this blood to the left ventricle. The right atrium collects deoxygenated blood from the body and then pumps this deoxygenated blood to the right ventricle. The left vertical…

acts as a muscular pump which is divided into 4 different chambers, the heart's main function is to pump the blood around the body. It pumps deoxygenated blood through the veins, to the lungs for oxygenation which can then be pumped into the various arteries. The transported blood therefore transports oxygen, hormones and nutrients to body tissues. The four chambers in the heart are known as the right atrium, left atrium, right ventricle…

Deoxygentated blood with which the blood flows into and out of the organ. Deoxygenated blood enters through the venae cava fills the right atrium (RA) and right ventricle (RV) through the tricuspid valve. Then, RV contracts pushing the blood to pulmonary circuit and returns oxygenated from the lungs and travels to left atrium (LA) and left atrium (LA) through the mitral valve. Left ventricle can be seen encased with thicker muscle in comparison to that…

tricuspid valve in the right side and the mitral valve in the left side. There are also the pulmonary and aortic valves that originate from the right and the left ventricles. The heart is located in the mediastinum. During embryonic development, oxygenated blood from the placenta flows into the right atrium through the inferior vena cava. Blood from the right atrium flows to the right ventricle to the pulmonary artery then to the DA which…

2.1. The left ventricle and interventricular septum The heart has two inferior chambers, called the right and left ventricles, respectively. These chambers are the “pumps” that expel 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,…

carried by the dhamani (arteries) and impure-deoxygenated blood by the sira (veins). Some common cardiac ailments and there Ayurvedic management is discussed below High blood pressure (Hypertension) Cause: Age factor is the leading cause of hypertension. With passage of time the elasticity of the blood vessels particularly arteries decrease and there is congestion of blood. Arteries undergo hardening (sclerosis) and the process is known as arteriosclerosis.…

Total Anomalous Pulmonary Venous Return Total anomalous pulmonary venous return (TAPVR) is a heart condition that children are born with (congenital). The blood vessels that are supposed to carry blood from the lungs to the left side of the heart go to the right side instead. In a normal heart, blood returns to the right side of the heart from all over the body. The right side of the heart pumps blood to the lungs, where the blood picks up oxygen. The oxygen-rich blood then flows to the left…
