      | Human Body Circulatory System - 
      Home Page | 
     
    
      |    The muscular heart 
		pumps blood out through tubes or vessels, called arteries.  These 
		branch repeatedly into microscopic capillaries that joint to form veins 
		that carry the blood back to heart.  Our anatomical models begin 
		with an overview of the Circulatory System and even include functional 
		models.  Next comes the arteries that carry the blood.  The 
		bulk of the pages are on the Human Heart.  The Starter Hearts vary 
		considerably, ranging from simple ones suitable for elementary education 
		to more advanced models.  The pages that follow portray 
		increasingly detailed models, including many suitable for advanced 
		medical school education.  These are suitable for internal medicine 
		and the study of cardiovascular diseases.
