This activity has two parts. In part A students stretch blood vessels (a piece of artery and a piece of vein) and measure how elastic they are. In part B they look at the histology of the blood vessels using a microscope.
21 Ιουν 2024 · 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 gives it a low resistance and enables it to accept a large volume of blood from the heart which is conducted to smaller ...
By the end of this section, you will be able to: Compare and contrast the three tunics that make up the walls of most blood vessels. Distinguish between elastic arteries, muscular arteries, and arterioles on the basis of structure, location, and function.
Part A: Elastic recoil in arteries and veins. 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. Attach a 10 g mass (see Figure 1) and record the length of the ring after the mass is added.
30 Οκτ 2023 · The larger vessels leaving the heart – namely the aorta, pulmonary trunk, common carotid, subclavian, vertebral and common iliac arteries – are elastic arteries. Elastic artery (histological slide) These larger vessels contain two additional layers – the internal and external elastic laminae.
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.
26 Δεκ 2019 · Top, the typical nonlinear relation between luminal pressure and area in large elastic arteries, explained by the progressive shift in load bearing from elastin to collagen fibers. Data translate into distensibility and pulse wave velocity (PWV) with the use of the Bramwell-Hill relation.
