The heart consists of several layers of a tough muscular wall, known as the myocardium. A thin layer of tissue, the pericardium, covers the outside, and another layer, the endocardium, lines the inside. Chambers and Valves The heart is divided into a right and a left heart, each subdivide...
When ventricle contract and A.V. valves close with a jerk, producing the first heart beat sound with low pitch “Lubb”. The second sound of the heart beat with high pitch “Dupp” is produced, when at the beginning of ventricular diastole the semi lunar valves close. The...
The heart features four types of valves which regulate the flow of blood through the heart. These valves have been clearly shown in the labeled diagram of the heart. They permit blood flow in one direction only, and prevent backflow of blood. The four types of valves are: Tricuspid Valve T...
Valves Facts about Human Heart Important Questions about the Human Heart Practise Labelling the Human Heart Diagram Introduction to the Human Heart The human heart is one of the most important organs responsible for sustaining life. It is a muscular organ with four chambers. The size of the hea...
In this context, metabolomics analysis of human stenotic valves characterized by varying degrees of disease severity can provide molecular-level information about the metabolites and metabolic pathways that are active at each stage of CAVS progression. In this paper we present the largest and most ...

Blood leaves the heart via the a) left atrium. b) aorta. c) right atrium. d) right ventricle. e) valves. After the blood in is the left heart you would next find it: a) entering the lungs. b) entering the tissues, ...

The molecular mechanisms of progressive right heart failure are incompletely understood. In this study, we systematically examined transcriptomic changes occurring over months in isolated cardiomyocytes or whole heart tissues from failing right and left
