Explanation:

the heart’s contraction cycle follows a dual pattern of circulation—the pulmonary (lungs)and systemic (body) circuits—because of the pairs of chambers that pump blood into the circulation. In order to develop a more precise understanding of cardiac function, it is first necessary to explore the internal anatomical structures in more detail.

The word septum is derived from the Latin for “something that encloses;” in this case, a septum (plural = septa) refers to a wall or partition that divides the heart into chambers.

Valves of the Heart: the septum between the atria and ventricles is known as the atrioventricular septum. It is marked by the presence of four openings that allow blood to move from the atria into the ventricles and from the ventricles into the pulmonary trunk and aorta. Located in each of these openings between the atria and ventricles is a valve, a specialized structure that ensures one-way flow of blood. The valves between the atria and ventricles are known generically as the tricuspid (right side)and the bicuspid (left side) valve. The valves at the openings that lead to the pulmonary trunk and aorta are known generically as the pulmonary and the aortic valve.

How does cell differentiation relate to gene expression.
Vilka [71]

Cell differentiation is how generic embryonic cells become specialized cells. This occurs through a process called gene expression. Gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a cell functions.
