GTU107 Cardiovascular System: Anatomy Quiz

Atria = Receiving chambers for blood returning to the heart from the circulation Ventricles = Discharging chambers of the heart

Pulmonary valve = Situated at the top of the infundibulum Mitral (bicuspid) valve = Guards the passage of blood from the left atrium to the left ventricle

Endocardium = Deepest layer of the heart, smooth lining to reduce friction of blood flow Myocardium = Middle layer of the heart, location of muscle fibers responsible for pumping

<p>Left coronary artery = Arises from the aortic sinus immediately above the left posterior cusp of the aortic valve Right coronary artery = Arises from the ascending aorta immediately above the aortic valve</p> Signup and view all the answers

<p>Pericardium = Surrounds and encloses the heart and roots of the great vessels The Heart = Located in the thoracic cavity in an area called middle mediastinum Pericardial cavity = Fibroserous sac that restricts excessive movements of the heart</p> Signup and view all the answers

<p>Restrict excessive movements of the heart = Function of pericardial cavity Serve as a lubricated container for heart contractions = Function of superficial fibrous pericardium Fibroserous sac that encloses the heart and roots of great vessels = Function of deep two-layer serous pericardium Chambered muscular organ that pumps blood through the circulatory system = Function of Pericardium</p> Signup and view all the answers

<p>Superficial fibrous pericardium = Part of pericardium composed of a deep two-layer serous pericardium Deep two-layer serous pericardium = Part of pericardium composed of a superficial fibrous pericardium Parietal layer = Part of deep two-layer serous pericardium Pericardial cavity = Part of superficial fibrous pericardium</p> Signup and view all the answers

<p>Thoracic cavity in an area called middle mediastinum = Location of the heart Middle mediastinum = Location where the pericardium lies Pericardial cavity = Location where different parts of the heart can contract Great vessels = Location enclosed by the pericardium</p> Signup and view all the answers
