Common carotid artery its right side below is the brachiocephalic trunk, and above, the trachea, the inferior thyroid veins, and the remains of the thymus; to its left side are the left vagus and phrenic nerves, left pleura, and lung. The left subclavian artery is posterior and slightly lateral to it. The cervical portions of the common carotids resemble each other so closely that one description will apply to both. Each vessel passes obliquely upward, from behind the sternoclavicular joint to the level of the upper border of the thyroid cartilage, where it divides. At the lower neck the two common carotid arteries
Endometrial arteries blood to the endometrium but are also beneficial during pregnancy. When a female is pregnant a placenta develops. The baby receives blood, nutrients and oxygen via the umbilical cord which is attached to the placenta. Between the placenta and the myometrium are intervillous spaces where the endometrial arteries supply blood to. The placenta has villous trees which allow for blood to circulate and then be transported to the baby via the placenta. Endometrial arteries are divided into the common ones and the arteriovenous anastomosis. The common ones are arteries that are homologous to the arteries of the rest of the
