Flow Valve Explain Ways Structure Aorta Related Function

The aorta is suited to its function by elastic tissue allowing stretching/recoil to smooth blood flow and maintain pressure; muscle for contraction to control flow; a thick wall to withstand pressure; smooth endothelium reducing friction; and the aortic valve preventing backflow.

A aorta é adaptada à sua função através do tecido elástico que permite esticar e recuar, suavizando o fluxo sanguíneo e mantendo a pressão; o músculo permite a contração para controlar o fluxo; a parede espessa resiste à pressão; o endotélio liso reduz o atrito; e a válvula aórtica impede o refluxo.

Front Explain four ways in which the structure of the aorta is related to its function. (4 marks)
Back 1.Elastic tissue to allow stretching / recoil / smoothes out flow of blood / maintains pressure;
2.(Elastic tissue) stretches when ventricles contract
OR
Recoils when ventricle relaxes;
3. Muscle for contraction / vasoconstriction;
4.Thick wall withstands pressure OR stop bursting;
5.Smooth endothelium reduces friction;
6.Aortic valve / semi-lunar valve prevents back flow
