Cardiovascular System Anatomy and Physiology: Study Guide for Nurses

Cardiovascular System Anatomy and Physiology

Circulatory System

The cardiovascular system of human body consists of three main components: Heart, Blood vessels and Blood. Heart is the pumping organ of the system, which.

** blood vessels

Structure of blood vessels. 3 distinct layers (tunics) that surround a central blood containing space, the vessel lumen.

The Aorta and Its Parts  The aorta ascends toward the right from the left ventricle. Then it curves posteriorly and to the left. It continues downward posterior to the heart and just anterior to the vertebral column, through the diaphragm, and into the abdomen (Figs. 11-4 and 11-5). The aorta is one continuousartery, but it may be divided into sections:

Histology of Blood Vessels: Wall Structure of Arteries and Veins

The structural and functional differentiation of arteries and veins is an important part of histology. This article prepares you for your exam.

Blood clot. Coloured scanning electron micrograph (SEM) of a blood clot from the inner wall of the left ventricle of a human heart. Red blood cells (erythrocytes) are trapped within a fibrin protein mesh (cream). The fibrin mesh is formed in response to chemicals secreted by platelets (pink), fragments of white blood cells. Clots are formed in response to cardiovascular disease or injuries to blood vessels. Connective tissue (orange) is also seen.

the microscopic blood vessels that carry nutrients to neurons in the brain, SEM. This sample, from Human cerebral cortex, shows a large blood vessel at the surface of the brain (top), which sends down thin, densely branched capillaries to deliver blood throughout the entire cortex.
