Investitigation of Veins and arteries. Research topic: the elasticity of cows vein and aorta hung with different masses.
LAVENDER’S PRATICAL REPORT of ELASTICITY OF
VEIN AND ARTERY
Research topic: the elasticity of cow’s vein and aorta hanged with different masses.
Hypothesis: the vein and aorta are to main blood vessels in our hearts which are very elastic. Depends on the function of each vessel, they are placed under different pressure. Through the arteries, blood is pumped to the body, while in through the vein, blood comes back to the heart. Hence, the elasticity of them is differentiated. Pumping blood to the whole body means higher pressure so that artery have thicker walls and more elastic than veins. In this experiment, I will examine the elasticity of these blood vessels.
