The aortic arch then branches into three major branches the brachiocephalic trunk (branches into right common carotid and right subclavian), the left common carotid artery, and the left subclavian artery. These three vessels provide blood to the head, neck, and upper limbs, and also part of the thorax. The descending aorta runs along the anterior spine and is called the thoracic aorta when it reaches the thorax. Later it becomes known as the abdominal aorta as it reaches the abdominal cavity. The abdominal aorta supplies the abdominal walls, viscera, and ends at T4 level where it branches into right and left common iliac arteries to supply the pelvis and lower limbs.
4. Identify each of the following in a lymph node: afferent lymphatic vessels and efferent vessels. a. afferent lymphatic vessels b. efferent lymphatic vessels c. What is the function of the macrophages within the lymph nodes? The macrophages within the lymph nodes filter lymph and remove bacteria and cellular debris before lymph is returned to the blood. d. Identify spleen functions.
The normal diameter of the aorta is around 2 cm. The abdominal aorta has several branches that include the celiac axis, which trifurcates into the left gastric, the splenic and the hepatic arteries, the SMA, the renal arteries and IMA. The celiac artery supplies the stomach, liver, pancreas, duodenum and spleen. It then branches into the left gastric (stomach), splenic (spleen) and common hepatic (liver) arteries. About one centimeter from the celiac axis, you find the SMA which supplies the small intestine, cecum and parts of the colon.
ANS -D: The temporo mandibular jo int receives blood fro m the arteries near it , which includes the external carotid and its terminal branches since the external carot id artery terminat es in the neck of the condyloid process of mandible. 1 5. ANS -D: The top of the skull appears rounded, whereas the sides appear flattened after the zygomat ic arches are removed. The p art of the skull just med ial to the zygomat ic arch is a depression. This flattened part of the skull and the depressed region above the zygomatic arch constitute the temporal fossa which in life is occupied by the temporalis muscle.

As we continue to make our way to the heart, we merge with the right external iliac vein. This is also another name for the femoral vein, and is also considered a deep vein in the lower leg. Its main responsibility is taking deoxygenated blood from the legs back to the heart. It is located right behind the inguinal ligament in the lower abdomen. The inguinal ligament support the area between the abdomen and the thigh (Inguinal Ligament, n.d.).
left upper quadrant spleen superior to stomach left hypochondriac region The stomach is medial and slightly inferior to the spleen. 10. Name the structures found within the mediastinum (seen on the x-ray). heart, esophagus, trachea, thymus, and several large blood vessels that enter and exit the heart. The mediastinum (located between the lungs in the thoracic cavity) contains the heart, thymus, esophagus, trachea, and several large blood vessels.
Blood flows past the aortic semilunar valve when the contracts. A. left atrium B. right atrium C. left ventricle D. right ventricle 5. Which is true? A. The left atrium contracts before the right atrium.
http://www.healthline.com/human-body-maps/tricuspid-valve The Pulmonic Valve: This valve is found between the right ventricle and the lungs. As the deoxygenated blood continues on its journey through the heart from the right ventricle, it makes its exit by way of the pulmonic valve. This structure is a one-way valve with prevents the flow of blood back into the right ventricle once it leaves the heart. http://www.healthline.com/human-body-maps/pulmonary-valve The mitral valve: This valve is located between the left atrium and the left ventricle. As the now oxygenated blood flows back through the left atrium, it does so under increased pressure.
The viscelar layer of the Bowman’s capsule and the endothelial capillary network of the glomerulus come together and form an endothelial-capsular membrane. This is where filtration of water and blood solutes occurs. Collecting ducts connect with distal tubules of nephrons in the medulla to help collecting ducts
