Both layers (parietal and visceral) are continuing each other with forming of the pleural cavity. The development of pleura in human embryo is important in separating the thoracic and abdominal cavities. To sum up, we present here basic information about embryology, histology and anatomy of pleura...
Body Cavities and Serous Membranes The body maintains its internal organization by means of membranes, sheaths, and other structures that separate compartments. Thedorsal (posterior) cavityand theventral (anterior) cavityare the largest body compartments (Figure 4). These cavities contain and protect d...
Anatomyand completely fills 1 of the non-symmetrical pleural cavities, which are situated on the left and right sides of themediastinumMediastinumThe mediastinum is the thoracic area between the 2 pleural cavities. The mediastinum contains vital structures of the circulatory, respiratory, digestive, and...
The thoracic lymphatic vessels are pulsating channels which drain actively the fluid of lung parenchyma interstitium and pleural cavities. Their unidirectional valves that avoid reflux of contents, direct the current of fluid to the connection of thoracic duct to subclavian vein or to the thoracic duct...
These lectures discuss the Mediastinum. Recall the mediastinum is that region of the chest cavity that lies in the middle, between the left and right pleural cavities. Anatomy of the Heart These lectures discuss the anatomy of the heart. ...
The human heart lies in the protective thorax, posterior to the sternum and costal cartilages, and rests on the superior surface of the diaphragm. The heart assumes an oblique position in the thorax, with two-thirds to the left of midline. It occupies a space between the pleural cavities ...
The anterior/ventral body cavity includes the thoracic cavity (which contains the lungs, each in its own pleural cavity, and the heart, in the pericardial cavity) and the abdominopelvic cavity (which contains the digestive organs in the abdominal cavity and the bladder and reproductive organs in...
Pneumothoraces are relatively common. They can occur with any injury to the pleural space that causes the negative intrapleural pressure to be lost. A small pneumothorax may be asymptomatic; however, a large pneumothorax typically presents with symptoms like chest pain and shortness of breath. The...
and rests on the superior surface of the diaphragm. The heart assumes an oblique position in the thorax, with two-thirds to the left of midline. It occupies a space between the pleural cavities called themiddle mediastinum, defined as the space inside the pericardium, the covering around the...
Which is an important function of the fluid in the pleural cavity? What is the function of the pinna? What holds the tooth in place in the tooth socket? Summarize the functions of the oral cavity. What are the functions of hyaline cartilage?
