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.
21 Ιουν 2024 · Distinguish between elastic arteries, muscular arteries, and arterioles on the basis of structure, location, and function; Compare and contrast the three types of capillaries on the basis of structure, location, and function; Describe the basic structure of a capillary bed, from the supplying metarteriole to the venule into which it drains
Large, elastic arteries are composed of cells and a specialized extracellular matrix that provides reversible elasticity and strength. Elastin is the matrix protein responsible for this reversible elasticity that reduces the workload on the heart and dampens pulsatile flow in distal arteries.
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.
Elastic Arteries - Free download as Word Doc (.doc), PDF File (.pdf), Text File (.txt) or read online for free. Your body's largest artery, the aorta, and its main branches constitute the "elastic arteries" When the left ventricle pumps blood into these arteries, they expand or swell.
Learning Objectives. Distinguish the elastic artery from the muscular artery. Key Points. Elastic arteries include the largest arteries in the body, those closest to the heart. They give rise to medium-sized vessels known as muscular, or distributing, arteries.
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.
