Protein domains are often found to be involved in specific protein-protein interactions, and so in theory protein domain shuffling could increase the complexity of protein interaction networks. However, in most cases, the old pathway would need to continue to function (to maintain species survival during the evolution of these new interactions). Consider whether alternative splicing could facilitate this process. If so, which specific type(s) of alternative splicing would be the most relevant?

Explanation:

The ventricles of the heart have thicker muscular walls compared to the atria. This is because blood is pumped out of the heart at greater pressure from these chambers if u compare to the atria. The left ventricle also has a thicker muscular wall than the right ventricle, as u know The heart has four chambers: two atria and two ventricles.

The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.

The right ventricle pumps the oxygen-poor blood to the lungs.

The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle. in the adjacent image. these r the aortic segments: ascending aorta, aortic arch, and descending aorta. Left subclavian artery separates the aortic arch from the descending aorta. Like other arterial structures, the aorta is composed of three layers: tunica intima, tunica media, and adventitia.
