The process in which the left cardiac ventricle is generated and organized.

OBSOLETE. Any process that involves recognition of a pathogen-associated molecular pattern, and by which an organism activates, maintains or increases the frequency, rate or extent of the innate immune response of a second organism, where the two organisms are in a symbiotic interaction.

The process in which the right cardiac atrium is generated and organized.

The process in which the cardiac atrium is generated and organized. A cardiac atrium receives blood from a vein and pumps it to a cardiac ventricle.

The process in which the left cardiac atrium is generated and organized.

The progression of the cardiac skeleton over time, from its formation to the mature structure. The cardiac skeleton is a specialized extracellular matrix that separates the atria from the ventricles and provides physical support for the heart.

A transition where an endocardial cushion cell loses apical/basolateral polarity, severs intercellular adhesive junctions, degrades basement membrane components and becomes a migratory mesenchymal cell that will give rise to the cardiac skeleton.

A transition where a cardiac epithelial cell loses apical/basolateral polarity, severs intercellular adhesive junctions, degrades basement membrane components and becomes a migratory mesenchymal cell that will contribute to the shaping of the coronary vasculature.

A transition where an endocardial cell loses apical/basolateral polarity, severs intercellular adhesive junctions, degrades basement membrane components and becomes a migratory mesenchymal cell that will contribute to the formation of the heart septum.
