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.
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
26 Δεκ 2019 · Highlights. •. Mechanistic origin of pressure-dependency of arterial stiffness and relation between stiffness and pulse wave velocity. •. Pathophysiological consequences of arterial stiffening. •. Overview of methods to assess regional and local arterial stiffness. •. (Graphical) appreciation of scrutiny of methods to quantify arterial stiffness.
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.
Take a look at this cross-section through an elastic artery, and identify the three main layers - tunica intima, tunica media and tunica adventitia. Elastic arteries: These arteries that receive blood directly from the heart - the aorta and the pulmonary artery.:
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.
Learning Objectives. 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.
