Structural Components of the Heart: Drag The Labels To Identify Structural Components Of The Heart

The heart is a vital organ responsible for pumping oxygenated blood throughout the body and removing deoxygenated blood. It consists of several structural components, each with a specific function crucial for the overall functioning of the heart.

The heart’s structural components include:

Chambers of the Heart

The heart consists of four chambers: two atria (singular: atrium) and two ventricles. The atria receive blood from the body and the ventricles pump blood out to the body.

• Right atrium:Receives deoxygenated blood from the body through two large veins, the superior vena cava and the inferior vena cava.
• Left atrium:Receives oxygenated blood from the lungs through four pulmonary veins.
• Right ventricle:Pumps deoxygenated blood to the lungs through the pulmonary artery.
• Left ventricle:Pumps oxygenated blood to the body through the aorta, the largest artery in the body.

Valves of the Heart

The heart has four valves that prevent the backflow of blood and ensure the proper direction of blood flow.

• Tricuspid valve:Located between the right atrium and right ventricle, it prevents the backflow of blood into the right atrium during ventricular contraction.
• Pulmonary valve:Located between the right ventricle and pulmonary artery, it prevents the backflow of blood into the right ventricle when the ventricle relaxes.
• Mitral valve (bicuspid valve):Located between the left atrium and left ventricle, it prevents the backflow of blood into the left atrium during ventricular contraction.
• Aortic valve:Located between the left ventricle and aorta, it prevents the backflow of blood into the left ventricle when the ventricle relaxes.

Septum

The septum is a muscular wall that divides the heart into left and right sides, preventing the mixing of oxygenated and deoxygenated blood.

• Atrial septum:Divides the right and left atria.
• Ventricular septum:Divides the right and left ventricles.

Pericardium

The pericardium is a double-layered sac that surrounds the heart, providing protection and lubrication.

• Fibrous pericardium:The tough outer layer that protects the heart from external forces.
• Serous pericardium:The inner layer that produces a fluid that lubricates the heart and reduces friction during contraction and relaxation.

Coronary Arteries

The coronary arteries supply oxygenated blood to the heart muscle itself.

• Left coronary artery:Branches into the left anterior descending artery (LAD) and the circumflex artery.
• Right coronary artery:Supplies the right side of the heart.

Sinoatrial (SA) Node

The SA node is a group of specialized cells located in the right atrium that generates electrical impulses, initiating the heartbeat.

Atrioventricular (AV) Node, Drag The Labels To Identify Structural Components Of The Heart

The AV node is a group of specialized cells located between the atria and ventricles that delays the electrical impulses, allowing the atria to fill with blood before the ventricles contract.

Bundle of His

The bundle of His is a group of specialized fibers that conducts the electrical impulses from the AV node to the ventricles, ensuring coordinated contraction.

Purkinje Fibers

The Purkinje fibers are specialized fibers that distribute the electrical impulses throughout the ventricles, ensuring rapid and synchronized contraction.
