The arterial blood supply of 40 carotid bodies in 20 Wistar rats of both sexes, aged 10–12 weeks (250–350 g), was examined by light microscopy. The carotid bodies of all rats were supplied by only one carotid body artery. The average diameter of the carotid body arteries was 40 μm. This artery arose either from the external carotid artery (97.5%) or the occipital artery (2.5%). There was an intimal cushion at the origin of the carotid body artery. The carotid body artery, after reaching the caudal pole of the carotid body, divided into the first‐order branch. In the carotid body, the paranchyma was divided into the second‐order branch. The carotid body artery was of the muscular type.
