Number of heart valves



Most of us know the role of the heart in the body and the role of blood, but what some do not know is the importance of heart valves in regulating all that work and blood flow.

What is the heart?

Is a muscle organ whose function is to pump blood from the veins of the arteries through the body. It is located in the middle part of the chest behind the sheath, about the size of a closed fist and weighs about 298 grams. It is a conical base at the back and its peak at the front.

Which consists of the heart

It consists of 4 rooms:

  • Right atrium: This room receives non-oxygenated blood from the body parts
  • Right ventricle: The oxygen-rich blood is pumped into the lungs under low pressure
  • Left atrium: Get oxygenated blood from the lungs
  • Left ventricle: Oxygen-rich blood is pumped into the body under high pressure

What are the valves of the heart?

One of the main components of the heart are the passages through which the blood flows through the heart of the body. It comprises four valves, namely the coronary, aortic, lung and thoracic valves. The valve consists of various rigid rings and flexible cells that move in a way that allows them to close and open. Heart and body a way forward and never back

How the heart valves work

  1. Open tri-balconies and crown tap:

    Blood flows from the right atrium of the right ventricle through the open triangular opening valve and from the left atrium of the left ventricle through the open coronary valve.

  2. Open the lung valve and aortic artery:

    The pulmonary valve opens at the start of the right ventricle Blood is pumped from the right ventricle through the pulmonary artery from the pulmonary artery to the lungs The aortic valve opens at the start of the left ventricle Blood is pumped from the left ventricle through the aortic valve of the aorta. From the body.

  3. Open the lung valve and aortic artery:

    The pulmonary valve opens at the start of the right ventricle Blood is pumped from the right ventricle through the pulmonary artery from the pulmonary artery to the lungs The aortic valve opens at the start of the left ventricle Blood is pumped from the left ventricle through the aortic valve of the aorta. From the body.

  4. Pulmonary and ventricular closed valves:

    When the right chamber ends, the contraction begins to relax and the active valve is closed, preventing blood from flowing back into the right chamber. The left ventricle also begins to relax when the contraction is complete and the aortic valve is closed, preventing blood flow to the left ventricle.
    This is repeated continuously allowing blood to flow to the heart, lungs and body

Types of valves

  • Tri-honor LED: The valve closes the right atrium that receives blood from the body and when opened, the blood flow from the right atrium can flow to the right ventricle and blood from the ventricle is prevented from flowing to the atrium when blood is pumped out of the ventricle .
  • Pulmonary valve: The valve closes the right chamber and then opens to allow blood flow from the heart to the lungs through the pulmonary artery, where it receives oxygen.
  • Metric valve: Close the left atrium that collects blood that comes out of the lungs and carries oxygen and when the valve opens Metric allows the passage of blood from the left atrium of the left ventricle.
  • Aorta LED: Close the left ventricle, which carries oxygen-filled blood before it is pumped to the body and then opened to allow blood from the heart from the left ventricle of the aorta and into the body.

Heart valve disorders

  • GERD: The valves do not close properly, which leads to blood flow in the heart and this is usually due to the swelling of the posterior valves and the so-called landing.
  • narrowing: TSMC is located in the wall of the valve, which leads to narrowing and reduction of blood flow through the valve.
  • stopThe non-forming valve is formed and forms a thick layer of tissue that inhibits blood flow in the chambers.

symptoms

  • An abnormal sound in the heartbeat is heard by the medical device
  • Fatigue and exhaustion
  • Shortness of breath especially when lying and moving
  • Swollen ankles and feet
  • dizziness
  • faintness
  • Irregular heartbeat

Risk factors

There are a number of things that increase the risk of heart valve disease:

  • Progress with age.
  • Some infections affect the heart.
  • Some heart disease or heart attacks.
  • High blood pressure, high cholesterol and diabetes.
  • Congenital heart disease.

complications

  • Heart failure.
  • Stroke.
  • Blood clots.
  • Heart defects.
  • 5. Death

Diagnosis of heart diseases

  • Stress tests: These tests help monitor the heart's response to movement and activity by increasing the patient's exercise and checking the heart's response to stress and diagnosing his condition.
  • Heart catheterization: This test is not usually used to diagnose heart valve disease, but is used when the diagnosis cannot be made and the severity of other tests cannot be determined.
  • Magnetic resonance imaging: Helps to take detailed and clear photos of the heart muscle to determine the severity of the situation and to assess the status and function of the rooms.
  • X-ray box: X-ray box helps detect heart valve diseases to inflate and determine lung health
