Write about four disorders of the circulatory system.

Answer 1

Circulatory system:

The circulatory system of the body consists of the heart and its blood vessels that supply blood to the different parts of the body.

Disorders of the circulatory system:

1. Coronary heart disease-

• The arteries of the heart are mostly affected due to the position of plaque.
• Plaque is a substance made of oil, cholesterol, cell debris, calcium, etc.
• When the buildup of plaque occurs in the arteries, hindrance is caused to the flow of blood.

2. Angina-

• Angina Pectoris is the medical name for chest pain that occurs due to coronary heart disease.
• The heart does not receive enough blood as the arteries of the heart are narrowed or blocked.
• The results are uncomfortable pressure and pain in the center of the chest.

3. Heart Attack-

• In medical terms, heart attacks are termed Myocardial Infarction.
• When enough blood does not reach the heart due to blockages, the heart muscle gets damaged, thus heart attack occurs.
• Some of the risk factors include high fat and cholesterol, high blood pressure, smoking, family history, diabetes, stress, obesity, inactive lifestyle, age, and gender.

4. Heart failure-

• It is a state when the heart does not pump blood enough to meet the needs of the body.
• A few symptoms include swelling of the ankles, fatigue, and an increased need to urinate at night.
• Rapid breathing, chest pain, and fainting are the immediate symptoms of heart failure.
