Introduction to Ventricle
The ventricles are the two largest chambers of the heart. The right ventricle pumps blood to the lungs, and the left ventricle pumps blood to the rest of the body.
Cardiac Anatomy
The heart is a muscular organ that is responsible for pumping blood throughout the body. The heart is located in the middle of the chest, between the lungs. The heart is divided into four chambers: the two atria and the two ventricles. The atria are the two upper chambers of the heart, and the ventricles are the two lower chambers of the heart. The heart is also divided into two circuits: the pulmonary circuit and the systemic circuit. The pulmonary circuit is responsible for delivering blood to the lungs, and the systemic circuit is responsible for delivering blood to the rest of the body. The heart is enclosed in a sac of tissue called the pericardium.
Right Ventricle
The right ventricle is a muscular chamber in the heart that pumps blood to the lungs. It is located on the right side of the heart and receives blood from the right atrium. The right ventricle contracts to pump blood into the pulmonary artery, which carries the blood to the lungs. The lungs oxygenate the blood, which then returns to the left side of the heart.
Left Ventricle
The left ventricle is the chamber of the heart that pumps oxygenated blood out to the body. It is one of the four chambers of the heart, and is located on the left side of the heart. The left ventricle is a muscular chamber that is responsible for the bulk of the work of the heart. It is composed of three layers: the epicardium, the myocardium, and the endocardium. The epicardium is the outermost layer, and is a thin layer of fibrous tissue. The myocardium is the middle layer, and is composed of cardiac muscle. The endocardium is the innermost layer, and is a thin layer of endothelial cells. The left ventricle is responsible for pumping oxygenated blood out to the body, and is the only chamber of the heart that can do this.
Ventricle Function
The ventricles are two large, muscular chambers in the heart that pump blood out of the heart. The left ventricle pumps blood to the body, and the right ventricle pumps blood to the lungs. The ventricles are thick and muscular because they have to work hard to pump blood throughout the body.
Ventricular Pathology
There are a few different types of ventricular pathology that can occur, including ventricular septal defect, ventricular tachycardia, and ventricular fibrillation.
Ventricular septal defect is a hole in the septum between the two ventricles of the heart. This can cause the blood to flow between the ventricles, which can lead to heart failure.
Ventricular tachycardia is a rapid heart rate that occurs in the ventricles. This can lead to a lack of blood flow to the rest of the body and can be life-threatening.
Ventricular fibrillation is a chaotic heart rhythm that occurs in the ventricles. This can lead to a lack of blood flow to the rest of the body and can be life-threatening.
