• Arteries/slagare = vervoer bloed WEG van die hart.
• Venes (are) = vervoer bloed NA die hart.
• Pulmonêre arterie = enigste arterie wat O₂- bloed vervoer.
• Pulmonêre venes (longare) = enigste vene wat O₂+ bloed vervoer.
• Tussen atriums en ventrikels – kleppe = atrioventrikulêre opening (2 soorte) = * trikuspidale en
** bikuspidale kleppe.
