Answer 1

1) Aorta is a part of systemic circulation . It arise from the left ventricle of the heart and supplies are oxygenated blood to the whole body .

2) ulnar vein is a part of systemic circulation which is present in the Upper limb region and carries the deoxygenated blood from the limb and drains into ultimately superior vena cava.

3) capillary bed in rectus femoris is a part of systemic circulation . The muscle that is present in the thigh and is involved in the systemic circulation. This muscle help in the extension of the knee joint.

4) Pulmonary vein is a part of Pulmonary circulation that carries the the oxygenated blood from lungs to the heart . It drains into left atrium .

5) adult carotid artery is a part of systemic circulation . It is present in the neck region on either side and is further divided into common carotid artery which further divides to form external and internal carotid artery.

6) pulmonary capillary blood derived from lobar arteries a part of Pulmonary circulation that helps in supplying the the oxygenated blood the whole lungs cells and maintains a air pressure Inside lungs .

7) , 8) both superior mesenteric and inferior mesenteric veins and arteries are a part of systemic circulation . It is found in the abdominal region behind the the greater omentum and is involved in the the transportation of Blood to various organs and muscles abdomen regions .

9) Rectus femoris is a part of systemic circulation . It is present in the thigh region and is involved in the extension of the knee joint .

10) splenic vein is a part of hepatoportal circulation. Splenic vein along with the superior mesenteric vein forms the hepatic portal vein which enters into the liver and carry deoxygenated blood.

11) left gastric artery is a part of systemic circulation involved in the the transportation of oxygenated blood to the gastric muscles and cells.

12) ,13) both bronchial artery and capillaries beds derived from the bronchial artery is a part of pulmonary circulation which is involved in the transportation of oxygenated blood to the lungs muscles and cells . Bronchi are the respiratory conducting part of the lungs.
