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...
The atria are thinly lined chambers of the heart towards the top that received blood from the veins of the body. The ventricles are thick chambers of the heart that pump blood towards the body and the lungs. Why is the left ventricle most important?
We classified the heart expression observed in the ZaCNE transgenic lines into 4 major categories (Fig.3dand Supplementary Fig.5a). Some heart enhancers broadly labeled all heart structures (Category I), while others showed specific or enhanced expression in the ventricle (category II), atrioventric...

Moreover, the structure of the heart, coupled with the sequential contraction of the chambers, produces complex flow patterns featuring vortical and reversing flows. Nevertheless, techniques developed for the zebrafish vasculature have been successfully adapted for use in the embryonic heart. As in the...
(c) the hagfish heart. The ECG is shown in the lower panel, with each of the major electrical waves labeled (see text for details). The coincidence of these electrical waves with the contractions and relaxations of the cardiac chambers can be seen by a comparison with the blood pressure...
With further maturation of the ventricles, MLC-2a expression is downregulated and disappears by E13.5 in ventricular chambers and is only expressed in the atria. Thus, further maturation of the selected MLC-2v-positive cardiomyocytes should better direct them into the ventricular lineage. We thus ...
bilaterally symmetric1,2. Subsequently, the heart tube undergoes rapid elongation and directional looping, during which it is remodeled into the characteristic configuration required for efficient blood circulation. Abnormal heart looping causes abnormal connections between the heart chambers and great vessels...
