The ascending aorta is the first part of the aorta that emerges from the left ventricle and rises up towards the arch of the aorta.

The aortic sinuses are three dilations located just superior to the aortic valve in the ascending aorta. They give rise to the coronary arteries and are important for blood flow to the heart muscle.

The arch of the aorta is a curved segment of the aorta that connects the ascending aorta to the descending aorta. It gives rise to major branches that supply the head, neck, and upper limbs.

The brachiocephalic artery is the first branch of the arch of the aorta, supplying the right side of the head, neck, and upper limb. It divides into the right common carotid artery and the right subclavian artery.

The descending thoracic aorta is the segment of the aorta that descends through the posterior mediastinum, supplying blood to the chest, abdomen, and back. It gives rise to numerous branches that supply the organs and tissues in this region.

The azygos venous system is a collection of veins on the posterior chest wall that drains blood from the back and abdomen. It drains into the superior vena cava.

The posterior intercostal arteries are a series of paired arteries that arise from the descending thoracic aorta and supply the intercostal muscles and the chest wall.

Variations in the azygos system occur in some individuals, such as an accessory azygos vein or an absent hemiazygos system, where the IVC drains into the azygos system instead.

A large lymphatic vessel that carries lymph from the abdomen, pelvis, left thorax, head, neck, upper and lower limbs.

Injury to the thoracic duct can result in leakage of chyle into the chest cavity.

A nerve that travels down the right side of the body, passing near the right brachiocephalic vein and superior vena cava.

A nerve that travels down the left side of the body, passing near the left subclavian artery.

A nerve that runs along the right side of the trachea.

A nerve that runs along the left side of the trachea, passing near the aortic arch.

A branch of the vagus nerve that supplies the vocal cords.

The transverse pericardial sinus is a space behind the aorta and pulmonary trunk, within the pericardial sac. It allows surgeons to isolate these vessels during operations.

The oblique pericardial sinus is a crescent-shaped space located posterior to the heart, within the pericardial sac. It is formed by the reflection of the parietal pericardium.

The parietal pericardium lines the pericardial sac, while the visceral pericardium covers the heart's surface. These layers are continuous at the heart's roots.

The fibrous pericardium is a tough outer layer that surrounds the heart, helping to anchor it within the chest. It is essential for protecting and supporting the heart.

Dextrocardia is a rare condition where the heart is positioned on the right side of the chest instead of the left.

Situs inversus is a condition where the major organs are mirrored, with the heart on the right and the liver on the left.

The recurrent laryngeal nerve branches off the vagus nerve, wraps around the aorta (left) or subclavian artery (right) before ascending back to the larynx.

The vagus nerve branches into plexuses that supply different organs in the chest and abdomen. The pulmonary plexus supplies the bronchi, the cardiac plexus supplies the heart, and the esophageal plexus supplies the esophagus.

The subclavian artery changes its name to the axillary artery at the lateral border of the first rib.

The brachial artery is located in the cubital fossa, a region on the anterior elbow.

The brachial artery divides into the radial and ulnar arteries in the cubital fossa.

The radial artery is commonly used for palpating the pulse at the wrist.

The superficial palmar, deep palmar, and dorsal networks make up the arterial supply to the hand.

The digital arteries supply the fingers and are end arteries, meaning they are the only source of blood supply for that region.

The dorsal venous network is the superficial network of veins on the back of the hand and drains into the basilic and cephalic veins.

The deep veins in the hand form venae comitantes, meaning they run alongside the arteries.

The point where the femoral artery passes beneath the inguinal ligament and becomes the femoral artery.

A swelling or bulge in the abdominal aorta, most commonly occurring just above the bifurcation.

The large vein that runs up the medial side of the lower limb, terminating by draining into the femoral vein.

The point where the common iliac artery splits into the internal and external iliac arteries.

Located at the back of the knee, this fossa contains the popliteal artery and vein, with the artery lying deep to the vein.

The vein that commences close to the lateral malleolus of the ankle and drains into the popliteal vein.

The artery that runs through one of the muscles in the medial compartment of the thigh, continuing from the femoral artery.

The point at the middle of the inguinal ligament, which also contains important structures like the femoral nerve and the femoral vein.

The foramen ovale is an opening in the interatrial septum of the fetal heart that allows blood to bypass the lungs. The fossa ovalis represents the closed remnant of the foramen ovale in adults.

The right atrium is the chamber of the heart that receives deoxygenated blood from the body via the superior and inferior vena cava. It pumps this blood into the right ventricle through the tricuspid valve.

The right ventricle is the chamber of the heart that receives deoxygenated blood from the right atrium and pumps it into the pulmonary artery to be oxygenated in the lungs.

The left atrium receives oxygenated blood from the lungs through the pulmonary veins and pumps it into the left ventricle through the mitral valve.

The left ventricle is the chamber of the heart that receives oxygenated blood from the left atrium and pumps it out to the body via the aorta.

The right atrioventricular groove is a sulcus on the surface of the heart that separates the right atrium from the right ventricle. It contains the right coronary artery and its branches.

The anterior interventricular groove is a sulcus that separates the right and left ventricles on the anterior surface of the heart. It contains the anterior interventricular artery (left anterior descending artery) and its branches, which supply the anterior wall of the ventricles with blood.

The blood flow through the heart follows this sequence: Right Atrium -> Tricuspid Valve -> Right Ventricle -> Pulmonary Valve -> Pulmonary Artery -> Lungs -> Pulmonary Veins -> Left Atrium -> Mitral Valve -> Left Ventricle -> Aortic Valve -> Aorta -> Body.
