| 4797244928 | left ventricle | The left lower chamber of the heart that receives blood from the left atrium and pumps it out under high pressure through the aorta to the body. |  | 17 |
| 4797254019 | bicuspid (mitral) valve | valve between the left atrium and left ventricle of the heart, consisting of two triangular flaps of tissue, that prevents blood from flowing back into the atrium when the ventricle contracts. |  | 18 |
| 4797261281 | aortic valve | the semilunar valve separating the aorta from the left ventricle that prevents blood from flowing back into the left ventricle |  | 19 |
| 5036879909 | coronary arteries | blood vessels that supply blood to your heart. They branch off of the aorta at its base. The right coronary artery, the left main coronary, the left anterior descending, and the left circumflex artery, are the four major coronary arteries. Blockage of these arteries is a common cause of angina, heart disease, heart attacks and heart failure. | | 20 |
| 5036942221 | right pulmonary artery | The main pulmonary artery is responsible for transporting oxygen-depleted blood from the heart toward the lungs. The main artery splits into the left pulmonary artery and the right pulmonary artery, each of which directs the blood to the corresponding lung (no picture available-arrow is pointing to left pulmonary artery) |  | 21 |
| 5036992368 | right pulmonary veins | returns blood from the right lung to the left atrium (no picture available-arrow should be pointing to veins on other side of heart) |  | 22 |
| 5037005031 | left pulmonary veins | returns blood from the left lung to the left atrium | | 23 |
| 5037021334 | ascending aorta | the largest vessel in the body. It transports oxygenated blood from the left ventricle of the heart to every organ. The aorta starts in the heart with the aortic valve; immediately adjacent is the aortic root, followed by the ascending aorta, the transverse aorta (the aortic arch), the descending aorta, and the thoracoabdominal aorta. The aorta ends in the abdomen |  | 24 |
| 5037117022 | brachiocephalic artery | is an artery of the mediastinum that supplies blood to the right arm and the head and neck. It is the first branch of the aortic arch and then divides into the right common carotid artery and the right subclavian artery. |  | 25 |
| 5037737257 | right common carotid artery | the left and right ___________arteries supply the head and neck with oxygenated blood; they divide in the neck to form the external and internal carotid arteries |  | 26 |

| 5037781601 | right subclavian artery | The __________arteries are two major blood vessels that supply oxygenated blood to the upper limbs and chest of the body. Both the of these arteries lie underneath the clavicle. The right carries blood to the right arm |  | 29 |
| 5037867308 | left subclavian artery | carries blood to the left arm |  | 30 |
| 5037899674 | thoracic or descending aorta | is subdivided into the thoracic aorta and the abdominal aorta. The thoracic aorta, the part of the aorta that runs from the arch of the aorta to the diaphragm, gives off numerous branches that supply oxygenated blood to the chest cage, esophagus & thoracic bones |  | 31 |
| 5037936414 | abdominal descending aorta | a continuation of the thoracic aorta and runs down to where the aorta ends (by splitting into the two leg arteries). The _______ supplies oxygenated blood to all of the abdominal and pelvic organs and the legs. |  | 32 |
| 5037987850 | celiac axis (artery/trunk) | is the first major branch of the abdominal aorta. supplies oxygenated blood to the liver, stomach, abdominal esophagus, spleen and the superior half of both the duodenum and the pancreas. |  | 33 |

| 5038085303 | splenic artery | It branches from the celiac artery, supplies oxygenated blood to the spleen & pancreas |  | 35 |
| 5038105352 | common hepatic artery | one of the final branches of the celiac artery. It supplies oxygen-rich blood to the liver, stomach, pancreas, omentum and duodenum |  | 36 |
| 5038143494 | superior mesenteric artery | arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies blood to the small & large intestines through two-thirds of the transverse colon, as well as the pancreas. |  | 37 |
| 5038186704 | right and left renal arteries | arise off the side of the abdominal aorta, immediately below the superior mesenteric artery, and supply the kidneys with blood |  | 38 |
