The remainder is supplied by the coronary vasculature which is primarily embedded in the pericardial fat on the surface of the heart and supplies predominantly the epicardium.

The heart external anatomy. Atria R L contract simultaneously. Besides lubrication the pericardium serves to hold the heart in position and maintain a hollow space for the heart to expand into when it is full. Part of the TeachMe Series.

Heart at rest. Superior vena cava posterior vessel that drains deoxygenated blood from the upper half of the body into the right atrium of the heart. Heart lies in the middle mediastinum.

The artery that directs blood from the heart to the lungs carries deoxygenated blood blood that has left its oxygen molecules in many cells so that it is now oxygen-poor. Vasculature of the Heart. The heart has five surfaces.

The muscular middle layer of the wall of the heart. The outer layer of the wall of the heart. Right left superior and inferior.

Heart External features Dr M Idris Siddiqui. Expand to accommodate blood flow Superior and inferior vena cavae return. The atria are separated from the ventricles by the coronary sulcus auriculoventriculargroove.

Blood forced into ventricles. The medical information on this site is provided as an information. The heart The Heart is a hollow muscular organ situated in the mediastinum of the thoracic cavity enclosed in the pericardium.

This contains the trunks of the nutrient vessels of the heart and is deficient in front where it is crossed by the root of the pulmonary artery. It is somewhat pyramidal in shape and placed obliquely behind the sternum and adjoining parts of costal cartilages so that 13rd of the heart is to the right of median. The inner layer of the heart.

The pericardium has 2 layersa visceral layer that covers the outside of the heart and a parietal layer that forms a sac around the outside of the pericardial cavity. Lower two chambers of the heart. Left and Right Atria superiorly Auricles are ear-like extensions of the atria.

It also has several margins. The endocardium and subendocardial tissue receive oxygen and nutrients by diffusion or microvasculature directly from the chambers of the heart. The artery that directs blood to the bodys cells carries oxygenated.

Ventricles R L contract simultaneously. The heart is made up of four chambers. Base - superior end of the heart where the great vessels enter and leave.

This tissue lines the inside of the heart and protects the valves and.

Name the artery that carries deoxygenated blood.

This is the muscular tissue of the heart. The walls of the heart are composed of an outer epicardium a thick myocardium and an inner lining layer of endocardium. The 4 major blood vessels appearing out of the heart are Superior Vena Cava Infe.

Unit 3 - External Anatomy of the Heart. It lies opposite to T5 T8 vertebrae in supine position T6 T9 vertebrae in erect position. Passive flow from atria into ventricles.

A review of the external anatomy of the heart and the great vessels. The division of the heart into four cavities is indicated on its surface by grooves. Fibrous Pericardium - the dense connective tissue that surrounds the heart.

Apex - the distal end of the heart that points downward and to the left. Base posterior diaphragmatic inferior sternocostal anterior and left and right pulmonary surfaces. One of two grooves that separates the ventricles of the heart.

The human heart consists of a pair of atria which receive blood and pump it into a pair of ventricles which pump blood into the vessels. The heart wall consists of three layers. Right pulmonary artery posterior vessel that carries deoxygenated blood from the right ventricle to the right lung.

Upper two chambers of the heart. The remainder is supplied by the coronary vasculature which is primarily embedded in the pericardial fat on the surface of the heart and supplies predominantly the epicardium. The right margin is the small section of the right atrium that extends between the superior and inferior vena cava.

About size of fist it is a hollow cone shaped organ with its apex at the bottom rests on diaphragm. The Heart is a muscular organ that collects the deoxygenated blood and sends it to the lungs for purification and pumps the oxygenated blood to the rest of the body. The Valves of the Heart.

13 rd of the heart lies to the right and 23 rd to the left of the midline. The internal partitions that form the four chambers of the heart produce grooves on the external surface called external sulci which include the coronary sulcus and the anterior and posterior interventricular sulci.
