Elastic arteries include the largest arteries in the body, those closest to the heart, and give rise to the smaller muscular arteries. The pulmonary arteries, the aorta, and its branches together comprise the body’s system of elastic arteries.
Elastic recoil in arteries and veins. Take rings of artery and vein tissue. Load and unload with 10 g masses and hence assess differences in elasticity. Consider how the elastic properties suit the different functions of artery and vein in the circulatory system.
30 Οκτ 2023 · In this worksheet we’ll be focusing on the arteries of the cardiovascular system, but you can test your knowledge of the veins and organs using our interactive cardiovascular system quizzes further down the page.
Elastic; aorta ____________ arteries have a thick tunica media with the greatest amount of elastin. They also experience the greatest pressure and the widest variation in pressure.
Part A: Elastic recoil in arteries and veins 1 Suspend a ring of artery from a hook on a clamp stand. Use a metre rule to record the length of the ring once the mass carrier has been attached to the free end of the ring. 2 Attach a 10 g mass (see Figure 1) and record the length of the ring after the mass is added.
The elastic recoil of the vascular wall helps to maintain the pressure gradient that drives the blood through the arterial system. An elastic artery is also known as a conducting artery, because the large diameter of the lumen enables it to accept a large volume of blood from the heart and conduct it to smaller branches.
30 Οκτ 2023 · The vessels of the body include arteries, arterioles, capillaries, venules and veins. This is in fact the order in which blood circulation occurs. Arteries and veins contain three layers: Tunica externa (outer layer) - comprised of elastic and collagen fibres; Tunica media (middle layer) - comprised of smooth muscle and elastic fibres
