Surface anatomy of heart and lungs

This document summarizes the surface anatomy of the heart, lungs, and pleura. It describes the blood supply and venous drainage of the heart. It details the borders, surfaces, and relations of the heart. It outlines the surface anatomy of the right and left pleura and lungs, including their anterior, inferior, and posterior margins. It notes the positions of the cardiac apex, costophrenic angle, and diaphragmatic copulae.

Circumflex Artery (The Continuation of Left Coronary Posteriorly) Right Coronary Artery The Left Coronary Artery Terminates By Anastomosis with Right Coronary Posterior Interventricular Artery
Venous Drainage of the Heart A- Coronary Sinus B- Anterior Cardiac Veins C- Vena Cordis Minimi
Coronary Sinus Opening of The Coronary Sinus Caval Openi ng A- Coronary Sinus 1.It is a wide venous channel situated in the posterior part of coronary sulcus and ends in the right atrium.
Tributaries of Coronary Sinus 1. Great cardiac vein: ascends with the anterior inter-ventricular artery, then curves with the circumflex artery. Small cardiac vein: accompanies the marginal artery. 2. Middle cardiac vein: accompanies the posterior inter- ventricular artery. 3. Small cardiac vein : accompanies the marginal artery . 4. Oblique vein of left atrium (of Marshal): descends obliquely on the back of the Lt. atrium. 5. Posterior vein of the left ventricle: to the left side of the middle cardiac vein.

ABC Surface Anatomy of the pleura a b g c d e h f d e a b c g h f Anterior margin: q Begins at the apex 1 inch above the medial 1/3 of clavicle. q Descends behind the sterno-clavicular joint. q Reaches the sternal angle. q Then, descends to the 4th costal cartilage. q The right pleura continues till the 6th costal cartilage. q The left pleura arches outwards and descends lateral to the sternal border making the cardiac notch, till it reaches the 6th costal cartilage. Inferior margin: q From the 6th costal cartilage, each line turns laterally passing around the chest wall crossing mid-clavicular line at 8th rib. q Mid-axillary line at 10th rib. q Midline posteriorly at 12th thoracic vertebra. Posterior margin: q From the 12th thoracic vertebra upwards till the apex.

Posterior margin: From the 10th thoracic vertebra upwards till the apex. Fissures: Oblique fissure (in both sides): From the 3rd thoracic spine to the 6th costal cartilage. Horizontal fissure (only in the right): From the 4th costal cartilage till it meets the oblique fissure.
