Answer to Question #39289 in Biology for Kevin

Question

Travel of a blood cell from the pinky toe through the body to the head and then back to the pinky toe. Where does the blood cell have to pass by

Answer 1

From the capillaries of the pinky toe blood is collected
-> in the larger veins of the lower limb (e.g. v. saphena magna) then
-> in the external and -> common iliacal vein -> inferior vena cava -> right atrium -> right ventricle -> pulmonary arteries -> capillaries of the lungs -> pulmonary veins -> left atrium -> left ventricle -> aorta -> branches of the aortic arch (arcus aortae) -> arteries of the head -> capillaries of the head -> veins of the head -> superior vena cava -> right atrium -> right ventricle -> pulmonary arteries -> capillaries of the lungs -> pulmonary veins -> left atrium -> left ventricle -> aorta -> descending aorta -> common iliac artery -> external iliac artery -> arteries of the lower limb -> capillaries of the lower limb (including those of the pinky toe)
