10 Questions
Match the heart chamber with its function:
Atria = Receiving chambers for blood returning to the heart from the circulation Ventricles = Discharging chambers of the heart
Match the heart valve with its location:
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
Match the heart wall layer with its description:
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
Match the arterial supply artery with its origin:
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
Match the heart wall layer with its function:
Endocardium = Smooth lining to reduce friction of blood flow Myocardium = Location of muscle fibers responsible for pumping
Match the following components of the heart with their descriptions:
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
Match the following dimensions of the heart with their correct measurements:
Long = 12 cm Broad = 9 cm Thickness = 6 cm Pericardium = Surrounds and encloses the heart and roots of the great vessels
Match the following functions of pericardium with their descriptions:
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
Match the following features of pericardium with their descriptions:
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
Match the following locations with their descriptions:
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
Test your knowledge about the anatomy of the cardiovascular system, focusing on the structure and functions of the heart. Learn about the chambered muscular organ that plays a crucial role in maintaining the flow of blood throughout the circulatory system.
