The cardiovascular system Flashcards
Ascending aorta
distributes oxygen and nutrients to the heart via the coronary arteries
Aortic arch
This has three major branches — the brachiocephalic trunk, the left common carotid artery, and the left subclavian artery
It sends blood to the upper body, including the head, neck, and arms
Descending aorta
The descending aorta sends blood to your torso, abdomen, and lower body
It’s referred to as the thoracic aorta above the diaphragm, but after passing the diaphragm, it becomes the abdominal aorta
Left and right common carotid
The left common carotid comes directly off the aortic arch, while the right common carotid comes from the brachiocephalic trunk
External carotid
These paired arteries are derived from the common carotid arteries. The external carotid supplies blood to areas like the face, lower jaw, and neck
Internal carotid
Like the external carotid, these paired arteries are also derived from the common carotid arteries. They’re the primary arteries supplying blood to the brain
Vertebral
Formed off of the subclavian arteries, these paired arteries travel up the neck, where they also supply blood to the brain
Thyrocervical trunk
Also derived from the subclavian arteries, the thyrocervical trunk branches into several vessels that send blood to the thyroid, neck, and upper back

Descending aorta
Arteries of the head and neck?
Left and right common carotid External carotid Internal carotid Vertebral Thyrocervical trunk
Arteries of the torso?
Bronchial Esophageal Pericardial Intercostal Superior phrenic
Bronchial
There are typically two bronchial arteries, one on the left and one on the right. They supply blood to the lungs
Esophageal
The esophageal artery provides blood to the esophagus
Pericardial
This artery supplies blood to the pericardium, which is a membrane that surrounds the heart
Intercostal
The intercostal arteries are a pair of arteries on either side of the body that send blood to various areas of the torso, including the vertebrae, spinal cord, back muscles, and skin
Superior phrenic
Like the intercostal arteries, the superior phrenic arteries are paired and deliver blood to the vertebrae, spinal cord, skin, and diaphragm
Arteries of the abdomen?
Celiac trunk Superior mesenteric Inferior mesenteric Inferior phrenic Adrenal Renal Lumbar Gonadal Common iliac Internal iliac External iliac
Celiac trunk
Branching off from the abdominal aorta, the celiac trunk divides into smaller arteries that supply organs such as the stomach, liver, and spleen
Superior mesenteric
Also branching off of the abdominal aorta, it sends blood to the small intestine, pancreas, and most of the large intestine
Inferior mesenteric
Like the superior mesenteric artery, this artery also branches off of the abdominal aorta and supplies blood to the last portion of the large intestine, which includes the rectum
