Vedclass · Answer

(D) The human heart is a myogenic organ composed of cardiac muscle. It consists of four chambers: two atria (right and left) and two ventricles (right and left). The sinus venosus is a structure found in the hearts of lower vertebrates like fish and amphibians,which acts as a pacemaker. In the human heart,the sinus venosus is incorporated into the wall of the right atrium during embryonic development to form the sinoatrial $(SA)$ node. Therefore,the human heart does not possess a distinct sinus venosus.
