Perikard

The video tutorial explores the anatomy of the heart, focusing on the pericardium, a two-layer sac that encloses the heart. It describes the fibrous outer layer and the serous inner layer, which contains a fluid film for smooth movement. The pericardium's connections to the diaphragm and sternum are explained, along with its role in preventing heart overstretching. The video also covers the pericardial fluid, sinus formations, and the blood supply and innervation of the pericardium, highlighting the involvement of the phrenic and vagus nerves.
