The «Angiology» section is dedicated to the study of the anatomy of the human cardiovascular and lymphatic systems. It covers in detail the structure of the heart, the aorta and its branches—from the carotid and subclavian arteries to the vessels of the extremities, head, brain, and internal organs.
Special attention is given to the venous bed, including the venae cavae system, the portal vein, the veins of the head, neck, and extremities, as well as key portacaval and cavacaval anastomoses. The patterns of lymph drainage, the structure of lymph nodes, ducts, lymphoid organs, and the thymus are examined, alongside the features of pulmonary circulation and fetal blood circulation.
During practical classes and exams, instructors most frequently ask about the topography of major vessels, the branches of the aortic arch and the external carotid artery, the sources of blood supply to the brain and abdominal organs, as well as collateral circulation pathways and clinically important anastomoses.
Where does the pulmonary circulation begin and where does it end?
It begins in the right ventricle of the heart (conus arteriosus), from where venous blood enters the pulmonary trunk, and ends in the left atrium, where oxygenated blood empties via four pulmonary veins.
Which arteries originate from the aortic bulb?
From the aortic bulb (specifically, from the right and left aortic sinuses), the right and left coronary arteries arise, supplying the heart.
At what level does the bifurcation of the common carotid artery occur?
Division into the external and internal branches occurs at the level of the upper border of the thyroid cartilage, which anatomically corresponds to the fourth cervical vertebra (C4).
What is the spatial relationship between the external and internal carotid arteries?
At the beginning of its course, the external carotid artery lies medial to the internal carotid artery. As it ascends, it crosses the internal carotid artery and comes to lie anterior to it.
What structures are supplied with blood by the inferior alveolar artery?
It supplies the teeth, alveoli, and gingiva of the mandible, the mylohyoid muscle, and its terminal branch exits through the mental foramen to supply the chin and lower lip.
What is the main difference between the internal and external carotid arteries in the neck?
In the cervical region, the internal carotid artery gives off no collateral branches. This is a crucial landmark for surgeons.
