ARTERIAL SYSTEM OF MAMMAL

  1. Basic plan from origin to distribution is similar in all vertebrates as per the mode of respiration.
  2. Main anterior aorta in terrestrial forms are carotid, systemic and pulmonary representing 3rd, 4th and 6th aortic arches respectively.
  3. Carotico-systemic aorta arises from left ventricle and before taking left turn it gives off a short innominate branch which later divides as left and right carotids supplying to head and neck Systemic aorta supplies to the body.
  4. There is only left systemic aorta that forms dorsal aorta passing along the vertebral column.
  5. Left subclavian branch arises from left systemic aorta and supply to arm, shoulder and nearby parts. The right subclavian arises from the right carotid since right systemic is absent.
  6. Pulmonary aorta arises from the right ventricle giving right and left branches.
  7. Posterior arteries from dorsal aorta, include mainly hepatic artery to liver; the coeliac artery supplying to stomach, esophagus and spleen etc., the anterior mesentric to small intestine and posterior mesentric to large intestine, urinary bladder, anus etc. and nearby parts; one renal artery to each kidney; iliac and femoral arteries to pehlic girdle and hind limbs.
  8. Dorsal aorta finally ferminates as caudal artery in tail (absent in man).
  9. All other branches of arteries are named according to the parts of body they supply to.
