Anatomy Of The Heart Vessels
Capillaries are thin-walled vessels composed of a single endothelial layer. The internal partition that divides the heart longitudinally is called the interatrial septum where it separates the atria and the interventricular septum where is separates the ventricles.

The base of the heart is located at the level of the third costal cartilage as seen in Figure 1.
Anatomy of the heart vessels. This passes around the right side of the heart to join the coronary sinus. The heart is made up of four chambers. The heart beats continuously pumping the equivalent of more than 14000 litres of blood every day through five main types of blood vessels.
In that way the direction of blood flow is always constant and unidirectional throughout the human bodyTherefore valves are extremely important. The aorta channels oxygen-rich blood to the body from the left ventricle. Intraoperatively the anatomy of the heart is viewed from the right side of the supine patient via a median sternotomy incision.
The right ventricle forms most of the anterior surface of the heart while the left ventricle forms the heart apex. The structures initially seen from this perspective include the. It originates at the apex of the heart and follows the anterior interventricular groove into the coronary sulcus and around the left side of the heart to join the coronary sinus.
Upper two chambers of the heart. The great veins the superior and inferior venae cavae and the great arteries the aorta and pulmonary trunk are attached to the superior surface of the heart called the base. A network of arteries and veins also carry blood throughout the body.
The right coronary artery divides into smaller branches including the right posterior descending artery and the acute marginal artery. Arteries arterioles capillaries venules and veins. A web of nerve tissue also runs through the heart conducting the complex signals that.
It takes in deoxygenated blood through the veins and delivers it to the lungs for oxygenation before pumping it into the various arteries which provide oxygen and nutrients to body tissues by transporting the blood throughout the body. The heart is a muscular organ about the size of a closed fist that functions as the bodys circulatory pump. The heart has four chambers two superior atria and two inferior ventricles.
The heart is a muscular pump that pushes blood through blood vessels around the body. Lower two chambers of the heart. The pulmonary veins bring oxygen-rich blood to the left atrium.
The right margin is the small section of the right atrium that extends between the superior and inferior vena cava. Heart valves are placed between the heart chambers and at the roots of great vesselsTheir function is to force blood to flow in only one direction preventing backflow regurgitation due to intra-arterial pressure. The arteriolar lumen regulates the flow of blood through the capillaries.
The heart has five surfaces. The coronary arteries run along the surface of the heart and provide oxygen-rich blood to the heart muscle. The outer layer of the wall of the heart.
An electrical system that stimulates contraction of the heart muscle. The small cardiac vein is also located on the anterior surface of the heart. In this article we explore the structure of the heart how it pumps blood around.
The muscular middle layer of the wall of the heart. Heart is divided into two by septum which further branches off and forms two superior atria and two inferior ventricles. There are also microscopic blood vessels which connect arteries and veins together called capillaries.
Veins are blood vessels which carry blood from the body back to the heart. It also has several margins. Right left superior and inferior.
These are different from the coronary vessels of the heart - which vascularise the heart muscle itself. MAJOR VESSELS OF THE HEART Vessels returning blood to the heart include. The arteries are the blood vessels that deliver oxygen-rich blood from the heart to the tissues of the body.
The great vessels of the heart are a collection of arteries and veins which drain blood into the atria and take blood away from the ventricles. Heart chambers and associated great vessels. There are a few main blood vessels which connect to different chambers of the heart.
The heart wall consists of three layers. Each artery is a muscular tube lined by smooth tissue and has three layers. Because of the thin walls of the capillary the exchange of nutrients and metabolites occurs primarily via diffusion.
Right coronary artery RCA. Base posterior diaphragmatic inferior sternocostal anterior and left and right pulmonary surfaces. The inner layer of the heart.
The right coronary artery supplies blood to the right ventricle the right atrium and the SA sinoatrial and AV atrioventricular nodes which regulate the heart rhythm. Heart is made up of three layers namely epicardium myocardium and endocardium wherein the general system of chambers valves veins and arteries all work together to circulate blood in the body. Together the heart blood and blood vessels arteries capillaries and veins make up the circulatory system.
Arteries are blood vessels which carry blood from the heart to the body.
