Handhaven van homeostase.
Homeostase = instant houden van het inwendige milieu. (Constant intern milieu)
Dubbele bloedsomloop:
Lichaamscirculatie. Vanuit de aorta -> weefsels en organen -> hart
Longcirculatie. Hart -> longen -> hart
Diastole: ventrikels ontspannen, bloed stroomt naar binnen. Bloed gaat vanuit het atrium
naar de ventrikels.
Systole: ventrikels trekken samen, bloed wordt weggepompt. (Naar de arteria pulmonalis en
de aorta)
• Door de druk verandering in de vaten worden de kleppen opengeduwd
Er zitten capillairspiertjes aan de (AV)kleppen, die zorgen ervoor dat de kleppen niet in de
verkeerde richting opengaan en er gaan bloed terugstroomt.
Isovulometrische = fasen waarin alle kleppen (AV en semilunair) gesloten zijn
Ventrikelcontractie:
• Isovulometrische contractiefase
- Alle kleppen zijn gesloten
- Toename druk in ventrikel
