Kidneys are also found in abdominal cavity. Why does the right lung have three lobes and the left lung has two. As the oxygen-rich air reaches these alveoli, the blood flowing through the capillaries takes up the oxygen in the method of diffusion occurring across the thin walls of the alveoli and the capillaries (the process in which a substance moves from an area of low concentration to an area of high concentration) [44]. There are not many treatment measures for the black lung disease as patients often need to manage the condition through some healthy lifestyle changes, like giving up smoking, getting enough fresh air, and stopping working at a mine [71]. The thoracic cavity contains the lungs and the heart, which is located in the mediastinum. d) pericardial cavity. This only affects people allergic to those substances [72].

The thoracic cavity contains the lungs and the heart, which is located in the mediastinum. The ventral cavity allows for considerable changes in the size and shape of the organs within it as they perform their functions. spinal cavity- spinal cord thoracic cavity- heart and lungs What is Epidermis?

The pericardial and pleural cavities (cavitas pericardialis and cavitas pleuralis) house the heart and lungs, respectively, and the larger peritoneal cavity (cavitas peritonealis) contains the majority of the abdominal organs.These are known as the ‘human body cavities.’ The body cavities are covered with a serous membrane (tunica serosa). These are the cavities created by serous membranes–the pleural cavities, the pericardial cavity, and the peritoneal cavity–and the mediastinum. It plays a crucial role in reducing the surface tension of the alveoli to prevent them from collapsing during gas exchange. The heart and lungs are located in the thorax, or chest cavity.
