Trace a drop of blood from the Right Ulnar Vein to the Splenic Artery.
Answer) Tracing of blodd from right ulnar vein to splenic artery-
Right ulnar vein
Right basilic vein
Right axillary vein
Right subclavian vein
Right brachiocephalic vein
Superior vena cava
Right atrium
Right atrioventricular valve (tricuspid valve)
Right ventricle
Pulmonary trunk
Pulmonary artery
Lungs
Pulmonary vein
Left atrium
Left atrioventricular valve (bicuspid valve)
Left ventricle
Ascending aorta
Arch of aorta
Descending aorta
Abdominal aorta
Coeliac trunk
Splenic artery
Explanation -
Right ulnar vein is deep vein of forearm, drains blood into the right basilic vein and then to the axillary vein in the arm.
Right Axillary vein becomes the right subclavian vein and then right brachiocephalic vein.
Right brachiocephalic vein combines with the left branhiocephalic vein to form superior vena cava.
Then this deoxygenated blood travels from superior vena cava to right atrium and ventricle and then to pulmonary trunk and artery.
Oxygenation of blood takes place in lungs and this oxygenated blood goes to left atrium and ventricle.
Aorta arises from the left ventricle.
The abdominal aorta gives a branch called coeliac trunk below the aortic opening of the diaphragm.
Coeliac trunk gives a branch called splenic artery, which is the largest branch.
