Question

Exercise 18-3 t hs exercise you will tace the blood flow through various circuits in the body. As you trace, keep the following hints in mind: Time to Trace! I Don't forget about the hepatic portal system. Remember most venous blood coming from the abdominal organs has to go through the hepatic portal vein and the hepatic portal system before it can enter the general circulation MATERIALS Laminated outline of the human body Water-soluble marking pen 1 Don't forget that the venous blood in the brain drains first into the dural sinuses, then into the internal jugular vein. I If you start in a vein, you have to go through the venous system, through the right heart, through the pulmonary circuit, and then through the left heart before you can get back to the arterial system. a If you start in an artery, you have to go through the artcerial system and then through a capillary bed before you can get to the venous system. You can't go backward through the arterial system-that's cheating 1 If you sart in an artery and end in an artery, you likdly will have to go through the arterial circuit, through a capillary bed, through the venous circuit, back to the heart and lungs, and then reenter the arterial circuit. Following is an example in which we have started in the right poplitcal vein and ended in the left internal carotid artery: Start: right popliteal veinright femoral vein right external iliac vein right common iliac vein +inferior vena cavaright atrium tricuspid valve right ventricle +pulmonary valve > pulmonary trunk + pulmonary artery+ pulmonary capillaries pulmonary veins left atrium mitral valve left ventride aortic valve ascending aorta aortic arch left common carotid artery left internal carotid artery-End Wasn't that easy? 486 Exploring Anatomy & Physiology in the Laboratory

Explanation / Answer

Start: Superior mesenteric vein --> Superior vena cava --> Right atrium --> Tricuspid valve -->Right ventricle --> Pulmonary semilunar valve --> Pulmonary trunk --> Pulmonary arteries --> Pulmonary arterioles --> Pulmonary capillaries --> Pulmonary veins --> Left atrium --> Bicuspid valve --> Left ventricle -->Aortic semilunar valve-->Ascending aorta-->Descending aorta --> right dorsalis pedis artery: End
