The heart is a vital organ of the body majorly responsible for the pumping of blood to vital parts of the body.
Structure If The Heart.
The human heart is a finely-tuned instrument that works for the health benefit of the whole body. It is a muscular organ around the size of a closed fist. The heart is situated at the chest's centre, below the sternum in a thoracic compartment. It is made up of four chambers and several valves that control the normal transportation of blood within the body.
The atria are positioned in the upper portion of the heart with the left atrium collecting oxygen-rich blood and the right getting oxygen-free blood. The valves that divide these chambers are known as atrioventricular valves, made of the tricuspid valve on the left and the mitral valve on the right.
On the other hand, ventricles are chambers located on the lower portion of the heart; they pump oxygen-enriched blood into the body's organs, it reaches even the smallest cells. Similar to the atria, valves also separate the ventricular chambers. Collectively termed as semilunar valves, these are made up of the pulmonary and aortic valves.
Functions Of The Heart.
As earlier mentioned, the heart is vital as it helps circulate or pump blood through the whole body. The heart helps transport blood via two pathways: the pulmonary circuit and the systemic circuit.
In the pulmonary circuit, deoxygenated blood flows through the right ventricle of the heart, passes through the pulmonary artery and moves to the lungs, then returns as oxygenated blood to the left atrium of the heart through the pulmonary vein.
In the systemic circuit, oxygenated blood is passed out of the body through the left ventricle to the aorta, and from there it is received by the arteries and capillaries where it gives the body's tissues oxygen. Deoxygenated blood returns through veins to the venae cavae and enters the heart's right atrium again.
Can The Heart Be Affected With Disease?
The heart is a delicate organ in the body that can be easily damaged if not properly taken care of. One of the most common complications of heart disease, heart failure starts when your heart becomes less effective in the pumping of sufficient blood to meet the needs of your body.
Heart damage can occur due to your daily unhealthy habits and intake of certain foods that are detrimental to the heart organ.
Once your heart is damaged, certain symptoms begin to show up. Some of them include:
1. Chest discomfort
People whose heart is damaged usually feel discomfort or pain in their chest region. This is mostly the common symptom of coronary artery disease.
2. Nausea, indigestion, heartburn, or stomach pain
Women have a higher risk of experiencing this symptom than men. This symptom of heart disease occurs due to a lack of proper diet and can occur when you have a heart attack.
3. Pain that spreads to the arm
The discomfort may feel like heaviness, fullness, squeezing, or pain. Having a feeling of discomfort in the upper body parts of your arms, back, neck, jaw, or stomach. This may have the feeling of pain or general discomfort.
4. Dizziness or lightheadedness
If you feel dizzy or lightheaded, it might be a sign of a damaged heart. If you also suddenly feel unsteady and you also have chest discomfort or shortness of breath, seek medical attention because it might be a sign of high blood pressure.
Sweating more than usual mostly if you aren't exercising or being active could be an early symptom of heart issues. Pumping blood through clogged arteries requires more effort from your heart, so your body sweats more to keep your body temperature down during the extra exertion.
6. Throat or jaw pain
When you have a heart attack, it can irritate your diaphragm and the nearby accessory nerve can lead to pain to refer elsewhere including your neck and shoulders.
7. Irregular heartbeat
If you have a heart attack, you may have scar tissue on your heart muscle. This scar tissue can lead to irregular or abnormal heartbeat.
Once you begin to notice these 7 signs in your body ensure to go for a diagnosis and proper medical care.
