Koronararterien und Herzvenen

The video tutorial provides an in-depth look at the coronary arteries and heart veins, explaining their roles in the vascular supply of the heart. It covers the anatomy and function of the left and right coronary arteries, including their branches and clinical significance. The tutorial also details the venous outflow system, highlighting the coronary sinus and other cardiac veins. The video concludes with interesting facts about heart function and oxygen saturation.

What is the primary function of the coronary arteries and heart veins?

• To supply the heart with oxygen and nutrients

• To filter blood impurities

• To regulate heart rate

• To control blood pressure

Which artery is abbreviated as LC in clinical terms?

• Anterior Interventricular Artery

• Right Coronary Artery

• Left Coronary Artery

• Circumflex Artery

What is the main role of the Ramus Interventricularis Anterior?

• Supplies the posterior wall of the left ventricle

• Supplies the anterior wall of the left ventricle

• Supplies the right ventricle

• Supplies the right atrium

From where does the right coronary artery originate?

• Left aortic sinus

• Right aortic sinus

• Pulmonary trunk

• Left ventricle

Which branch of the right coronary artery supplies the sinus node?

• Ramus Nodi Atrioventricularis

• Ramus Marginalis

• Ramus Nodi Sinoatrialis

• Ramus Interventricularis Posterior

What is the primary function of the coronary sinus?

• To supply oxygenated blood to the heart

• To filter blood impurities

• To regulate heart rhythm

• To collect deoxygenated blood from the myocardium

Which vein is known as the Wehner Cardiaca Magna?

• Small Cardiac Vein

• Anterior Cardiac Vein

• Coronary Sinus

• Great Cardiac Vein

What is the role of the Trans Moral System veins?

• To filter blood impurities

• To supply oxygenated blood to the heart

• To collect venous blood directly into the right atrium

• To regulate heart rhythm

Where are the Endo Morale System veins primarily found?

• Left atrium

• Right atrium

• Left ventricle

• Right ventricle

Why is the blood in the left ventricle not fully saturated with oxygen?

• Due to poor lung function

• Due to low blood pressure

• Due to high heart rate

• Due to mixing with venous blood
