Heart And Lungs Anatomy

Anterior border of lungpleura run inferior to 2 6 rib parasternally continue infero laterally to rib 8 at mid clavicular line rib 10 posteriorly. The heart lies between the two lungs and is enclosed within a fibrous bag the pericardium while each lung is invested by a serous membrane the pleura.

Heart and lungs anatomy. The human heart is located within the thoracic cavity medially between the lungs in the space known as the mediastinum. The two lungs are not a mirror reflection of one another. These lobes are further divided giving 10 bronchopulmonary segments which are the functional units of the lung tissue.

Within the mediastinum the heart is separated from the other mediastinal structures by a tough membrane known as the pericardium or pericardial sac and sits in its own space called the pericardial cavity. The lungs are covered by a thin tissue layer called the pleura. This is blood that is carrying carbon dioxide rather than oxygen.

Heart and lung anatomy this image shows the anatomy of the heart and the lungs in relation to each other displaying their different parts and features and the vessels of the heart and their relation to the lungs. As the blood passes through the tiny thin walled capillaries they get oxygen. Your heart sends deoxygenated blood to the lungs.

The right lung has three lobes. The hilum of the lung is a passage for the pulmonary artery two pulmonary veins and the main bronchus as well as bronchial arteries and veins nerves and lymphatic vessels. The same kind of thin tissue lines the inside of the chest cavity also called pleura.

Figure 1 shows the position of the heart within the thoracic cavity. Cerivical pleura and apex reach above clavicle. Pleura continues to 12th rib and spinous process of t12.

The heart and lungs are situated in the thorax the walls of which afford them protection.
