AB The  main  function  of  the  cardiovascular  system  is  to  transport  materials  such  as  hormones  and  nutrients  to  the  cells  of  the  body  and  to  remove  secretions  and  waste  products.  The  energy  of  the  heart’s  contractions  propels  the  blood  through  the  blood  vessels  to  all  of  the  tissues  of  the  body.  The  arteries  carry  blood  away  from  the  heart  and  branch  into  progressively  smaller  vessels.  The  smallest  vessels  are  the  capillaries,  with  walls  consisting  of  only  one  cell  layer  of  simple  squamous  endothelium.  The  systemic  capillaries  are  the  site  of  exchange  of  materials  between  the  blood  and  body  tissues.  The  pulmonary  capillaries  are  the  site  of  exchange  between  the  blood  and  the  alveolar  gas.  The  capillaries  are  so  numerous  and  well  distributed  that  almost  no  cell  in  the  body  is  greater  than  70  μ  away  from  a  capillary.
