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.

What is the primary function of the pericardial fluid?

• To remove waste products from the heart

• To provide nutrients to the heart

• To act as a low-friction bearing

• To supply oxygen to the heart

How is the pericardium connected to the diaphragm?

• By the tunica adventitia

• With the mesotes epithelium

• Via the ligamenta stern operi Kadia

• Through the Afrin operi Kadia ligament

What prevents the pericardium from overstretching the heart?

• The serous layer

• The sinus obliquus

• The pericardial fluid

• Collagen-rich fiber traits

Which structure is found between the left and right pulmonary veins?

• Sinus obliquus pericardium

• Sinus transversus pericardium

• Lamina viscerales

• Lamina parietalis

What is the source of the pericardium's blood supply?

• Pulmonary trunk

• Superior vena cava

• Internal thoracic artery

• Azygos vein
