Cerebral artery

Vedclass · Answer

(C) In the circulatory system of a frog,the heart pumps blood through various arteries. The frog possesses a pair of systemic arches (left and right) that arise from the truncus arteriosus. It also has carotid arteries supplying the head region and renal arteries supplying the kidneys. However,there is no specific vessel named the 'cerebral artery' that functions as a primary systemic trunk in the frog's anatomy. The brain receives blood primarily from the carotid arteries. Therefore,the cerebral artery is considered absent as a distinct major artery in this context.
