Question

Name the membranes that cover the heart.

Answer 1

Hint: The heart is a muscular organ that is available simply behind and slightly left of the breastbone. The heart is a group of tissues that works together to perform a specific function. The larger part of the heart is made up of cardiac muscles. It is an organ that pumps blood throughout the body by the circulatory system. The heart transports nutrients and oxygen to the tissues. It removes waste and carbon dioxide.

Complete answer:
The human heart contains four chambers, two auricles and two ventricles.
-Atria are the two chambers that are present on the upper portion of the heart and it receives the blood which is free from oxygen.
-Atrioventricular is the tricuspid valves on the left and mitral valve on the right. It separates the atria chambers.
-Below atrioventricular, the ventricular valve is present which pumps oxygenated blood throughout the body. Like atria, the ventricular valve is separated by a semilunar valve. Semilunar valves are made up of pulmonary and aortic valves.
-Pericardium: It is the membrane that covers the heart. Pericardium membrane is a thin double-layer membrane. This membrane protects the heart from external blows and injuries.

Additional Information:
-The heart helps the body in maintaining constant body temperature.
-The heart protects the body from blood loss and infections.
-The heart maintains fluid balance within the body.
-The heart consists of four valves: pulmonary, tricuspid, mitral, and aortic valves.

Note:
The heart is a muscular organ that is present just behind and slightly left of the sternum. It is a crucial organ of the human body. The heart pumps blood throughout the body and provides nutrients to all the organs, tissue, and cells of the body and removes waste material. It receives deoxygenated blood from the body and transports oxygenated blood to the body. The arteries take blood away from the heart and the veins carry blood back to the heart. It pumps about 2000 gallons of blood in a day.
