Each lung consists of. The heart wall consists of three layers. The heart and lungs work together to get oxygen to the tissues.
Right atrium and ventricle of the heart labeled The right atrium and ventricle receive deoxygenated blood from systemic veins and pump it to the lungs while the left atrium and ventricle receive oxygenated blood from the lungs and pump it to the systemic vessels which distribute it throughout the body. An adult heart has a mass of 250350 grams 912 oz. The heart and lungs are situated in the thorax the walls of which afford them protection.
The lungs are covered by a thin tissue layer called the pleura. Left anterior pulmonary vein. The muscular middle layer of the wall of the heart.
Because the heart is between the lungs the left lung is smaller than the right lung and has a cardiac notch in its border to accommodate the heart. Just inside the chest the heart circulates blood from around the body to the lungs where the blood receives oxygen from capillaries. 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. The heart and lungs together with the blood vessels comprise the cardiovascular system. It then returns the blood to the heart which pumps the freshly oxygenated blood to the rest of the body.
Upper two chambers of the heart. The heart pumps blood from the body to the lungs where the blood is oxygenated. The chest or thorax is the region between the neck and diaphragm that encloses organs such as the heart lungs esophagus trachea and thoracic diaphragm.

This oxygen-rich blood then circulates throughout the body to nourish the cells. WebMDs Lungs Anatomy Page provides a detailed image and definition of the lungs. Every breath you take pulls oxygen into your lungs to supply.
Left main bronchus 3. Oxygen-depleted blood gets collected from the tissues to be oxygenated in the lungs. The heart pumps the blood and the lungs put oxygen into it.
