The carotid arch of a frog refers to the arterial structure that branches from the heart and supplies blood to the head and neck region. In amphibians like frogs, the carotid arch divides into the left and right carotid arteries, which further branch out to provide oxygenated blood to the brain and other facial structures. This adaptation is crucial for their respiratory and metabolic needs, especially during their active lifestyles.

The artery that extends up to a frog's head is called the carotid artery. It is responsible for supplying blood to the head and brain. In frogs, the carotid artery branches off from the aortic arch and plays a crucial role in their circulatory system.
In the carotid sinus and the aortic arch
The arch of the aorta has three large arteries arising from it: the brachiocephalic, the left common carotid and the left subclavian. The brachiocephalic divides into the right common carotid and the right subclavian.

In the human, the right common carotid artery branches from the brachiocephalic artery, whereas the left common carotid artery comes directly from the aortic arch. In the cat, both common carotid arteries branch from the brachiocephalic artery.

negative feedback via baroreceptors in the carotid artery and aortic arch
The baroreceptors, located in the carotid sinuses, respond to changes and absolute levels of blood pressure. These nerves go to centers in the brain stem and trigger changes in heart rate and venous tone.
