How to distinguish the tricuspid valve and the difference between the tricuspid valve and the mitral

1. The location is different.

Mitral valve. Located in the left atrium.

Between the left ventricle, the valve morphologically connects two leaflets to the chordae tendinae within the ventricle.

Tricuspid valve. Located between the right atrium and right ventricle, it is morphologically connected by three leaflets connected to the chordae tendinae in the ventricle.

2. Different forms.

Mitral valve: The valve is morphologically connected by two leaflets to the chordae tendinae within the ventricle.

Tricuspid valve: morphologically connected by three leaflets to the chordae tendinae within the ventricles.

3. The role is different.

Mitral valve: Prevents blood from the left ventricle from flowing back to the left atrium.

Tricuspid valve: Prevents blood from the right ventricle from flowing backwards back into the right atrium.

Abstract:The main structures of the heart and large blood vessels include right atrium, right ventricle, pulmonary artery, left atrium, left ventricle, and aorta, and the atrium and ventricle are connected by the atrioventricular valve, the right side is called the tricuspid valve, and the left side is called the mitral valve.

The main structures of the heart and large blood vessels include right atrium, right ventricle, pulmonary artery, left atrium, left ventricle, aorta, and the atrium is connected by an atrioventricular valve, the right side is called the tricuspid valve, and the left side is called the mitral valve.

The valves between the aorta and the left ventricle and between the pulmonary artery and the right ventricle are called the aortic valve and the pulmonary valve, respectively. There is a thin muscular septum between the left and right atrium, and a thick muscular septum between the left and right ventricles, which are called atrial septum and ventricular septum, respectively. All of these structural abnormalities can affect the function of the heart to a greater or lesser extent.

There are two pathophysially distinct types of cardiac arrest, primary cardiac arrest, in which arterial blood is often oxygenated in the presence of cardiac arrest, and cardiac arrest, secondary to respiratory failure, in which initial cardiac output is normal but hypoxemia, hypotension, and secondary cardiac arrest due to lack of ventilation.

Different resuscitation measures should be used for these two different types of cardiac arrest, with chest compressions requiring only chest compressions, while traditional CPR (chest compressions plus ventilation) should be performed in the latter. Respiratory arrest is often caused by food choking, drowning, drug or alcohol overdose, and respiratory problems.

Cardiac arrest occurs during hospitalization, and most patients with VF-CA in the hospital can be diagnosed and defibrillated during periods of electrical activity. In addition, the CPR National Registry of Hospital Arrest indicates that the majority of patients** are noncardiogenic, and ventilation and chest compressions are important in these patients.

2. Different forms.

Mitral valve: The valve is morphologically connected by two leaflets to the chordae tendinae within the ventricle.

Tricuspid valve: morphologically connected by three leaflets to the chordae tendinae of the limb within the ventricle.

3. The role is different.

Mitral valve: Prevents blood from the left ventricle from flowing back to the left atrium.

Tricuspid valve: Prevents blood from the right ventricle from flowing backwards back into the right atrium.

1. Different locations: mitral valve, located between the left atrium and the left ventricle, the valve morphologically connects the two valve leaflets with the chordae tendinae in the ventricle. The tricuspid valve, located between the right atrium and right ventricle, is morphologically connected by three leaflets connected to the tendon and wheel cord in the ventricle.

2. The role is different: The mitral valve has the effect of preventing the blood flow of the left ventricle back to the left atrium. The tricuspid valve, which prevents blood from the right ventricle from flowing backwards back into the right atrium.

1. The tricuspid valve is like a "one-way valve" to ensure that the blood circulation must flow from the right atrium to the right ventricle and through a land fiber. When the right ventricle of the heart contracts, it squeezes the blood in the chamber, and the blood hits the valves.

2. The tricuspid valve is closed, and the blood does not pour into the right atrium. There is a pulmonary artery ostine above the anterior preventricle of the right ventricle, from which blood from the right ventricle is sent to the pulmonary artery. There are three half-moon-shaped valves on the mouth of the pulmonary artery called the pulmonary valve, and when the ventricles are dilated, the pulmonary valve closes and blood does not flow backwards into the right ventricle.

The mitral valve is the left atrioventricular valve, also known as the "monk's hat valve". It attaches to the left fibrous atrioventricular ring and is formed by the fold of the endocardium. There are two valves, the anterior and medial is the anterior cuspid valve, which is larger, often called the large valve, and is the demarcation marker between the left ventricular inflow tract and the outflow tract; Those located on the posterolateral side are posterior cuspid valves, which are smaller and often called small valves.

The valve is triangular in shape with the tip towards the left ventricular cavity. The bottom edges of the two valves are often fused to each other, sometimes with small side valves between the two valves.
