Each of the four primary organs that make up the human circulatory system has a specific role to play in the smooth flow of blood to each portion of the body. These four organs work together to form the circulatory system. Included among the essential components of the circulatory system are the Heart, Blood, Blood vessels, and lymphatic system.

A disorder is characterized as a situation when the body is not operating normally. Any illness affecting the heart, blood arteries, or blood cells is considered a circulatory system condition. Blood, oxygen, hormones, and nutrients are not transported to the tissue and cells in sufficient amounts or at reduced rates as a result of this condition.

Disorder of the Circulatory System

Hypertension (High blood pressure)

The pressure of the blood against the artery walls is referred to as blood pressure. High blood pressure results if this pressure occurs frequently or continues. Hypertension is defined as blood pressure greater than 120/80 mm Hg. To pump blood to the other organs, the heart must work hard, which is indicated by high blood pressure. The silent murderer is high blood pressure. Chronic nephritis, blindness, and temporary or permanent paralysis are all results of it harming the arteries in the brain, eyes, or kidneys, respectively.


  1. Headache.
  2. Dizziness. 
  3. Nose bleeding. 
  4. Pain in the chest.
  5. Difficulty in breathing.
  6. Blood in the urine.


  1. Anxiety or stress.
  2. A few drugs, such as steroids, birth control pills, etc.
  3. Thyroid problems
  4. Kidney disease, diabetes 
  5. Specific birth defects


  1. Consuming a salt-free, heart-healthy diet.
  2. Performing regular exercise.
  3. Limits on alcohol.
  4. No smoking.
  5. Sleeping 7 to 9 hours every day.
  6. Keeping a healthy weight or losing weight.
  7. Medications.

Coronary Artery Disease (CAD)

Atherosclerosis is another name for coronary artery disease. The condition known as coronary artery disease is brought on by the buildup of waxy substances in the blood channels that carry blood to the heart muscle, which blocks the blood flow. Waxy substances include things like fat, cholesterol, and fibrous fibers. It could therefore result in a heart attack.


Before a heart attack or stroke, symptoms could not show up at all. This happens unexpectedly. Which arterial blockage is present affects the symptoms. 

  1. Breathing difficulties and weakness are signs that it is in the carotid arteries, which supply the brain with blood.
  2. Severe paralysis
  3. Migraine

The following symptoms will appear if the coronary arteries, which supply blood to the heart, are blocked:

  1. Chest discomfort 
  2. Nausea
  3. Cough
  4. Weakness
  5. An unexpected arm or leg weakness


  1. High consumption of cholesterol
  2. Elevated blood pressure
  3. High sugar levels
  4. Smoking.
  5. Abuse of alcohol 
  6. Arthritis
  7. Overweight
  8. Anxiety
  9. Eating less food with fiber
  10. No exercise 


  1. A balanced diet
  2. Making lifestyle changes, such as giving up drinking and smoking. 
  3. Medications.
  4. Surgery.


It indicates chest pain. The coronary arteries’ arteriosclerosis is the cause of it. As arteries in this condition cannot extend or expand substantially, they cannot deliver extra blood to the heart muscle when it is under stress and the heart is pumping more rapidly. The heart’s muscles hurt as a result of insufficient oxygen. This pain lessens after a while, however, it is an indication of a heart attack.


  1. Chest pain
  2. Sweating 
  3. Tiredness
  4. Dizziness
  5. Nausea, etc.


  1. High blood pressure.
  2. Blockage of important heart arteries 
  3. Diabetes
  4. Obesity 
  5. Tobacco usage
  6. Family history is a factor.
  7. Stress
  8. Valve narrowing


  1. A person with angina should consult a physician.
  2. Medicines like aspirin may be used by doctors to treat angina.
  3. Angioplasty, in which blocked arteries are opened with the help of balloons or stents to improve blood flow to the heart.

Heart Failure

The inability of the heart muscle to pump enough blood to meet the body’s needs for blood and oxygen causes heart failure, a chronic, progressive condition. In essence, the heart is overloaded by its workload. Because congestion in the lungs is the primary sign of heart failure, it is occasionally referred to as congestive heart failure.


  1. Breathlessness when resting down or exercising
  2. Weakness and tiredness
  3. Having trouble focusing or being less alert
  4. Legs, ankles, and feet swelling
  5. Belly-area swelling
  6. Irregular or fast heartbeat
  7. A lack of appetite and nausea


  1. Uncontrolled hypertension
  2. Sleep issues
  3. Uncontrollable diabetes
  4. Excessive alcoholic beverage use
  5. Abnormal heartbeat
  6. A few medicines, including antiarrhythmic meds and nonsteroidal anti-inflammatory drugs (NSAIDs).
  7. Infection of the cardiac muscles by a virus
  8. Obesity


  1. Reduce your salt (sodium) consumption.
  2. Engage in regular exercise
  3. Stop smoking.
  4. Limit your alcohol intake.
  5. Medicines
  6. Surgeries

Coronary Thrombosis

The development of a blood clot inside a cardiac blood artery is known as coronary thrombosis. A myocardial infarction, often known as a heart attack, or damage to heart tissue may result from this blood clot restricting blood flow within the heart. The most frequent cause of coronary thrombosis is atherosclerosis, which is a buildup of cholesterol and lipids in the walls of the arteries. Less blood can flow through the decreased vessel diameter, which speeds up the development of myocardial infarction.


  1. Behind the breastbone chest pain
  2. Extreme drowsiness
  3. Ache to extend down the left arm
  4. Headache, jaw, and ear pain
  5. Shortness of breath or difficulty breathing
  6. A sensation of stiffness in the throat
  7. Fainting


Plaque build-up from deposits of fat, calcium, cholesterol, and other substances causes one or more coronary arteries to become clogged.


  1. As long as you are not allergic to aspirin, a doctor may give you aspirin right away if they believe you have coronary thrombosis. This medicine aids in preventing platelets from congregating to create a bigger clot.
  2. Once the thrombosis has been located, you might need an urgent procedure to get your heart’s blood flow back to normal. The artery can be reopened using a cardiac catheter, commonly known as balloon angioplasty.
  3. A blood clot extraction may potentially be an option for certain patients. According to doctors, eliminating the clot may reduce the chance of dying. If a blood clot is large, this technique may be extremely beneficial.
  4. A stunt, which is a mesh tube inserted into a blood channel to assist expand it and improve blood flow, may be used to treat smaller clots more effectively.
  5. To dissolve a clot, you might also need to take medicine. These medications are often given through injection or IV during your hospital stay.
  6. No smoking
  7. No intake of fast food.

FAQs on Disorder of the Circulatory System

Question 1: Define disorder. Mention the name of disorders of the human circulatory system.


When the body is not functioning regularly, it is said to have a disorder. A circulatory system condition is any disease affecting the heart, blood vessels, or cells. Disorders of the human circulatory system:

  1. Hypertension (high blood pressure)
  2. Coronary Artery Disease (CAD)
  3. Angina
  4. Heart failure
  5. Coronary Thrombosis

Question 2: Write about Angina pectoris.


Chest pain or pressure, often known as angina or angina pectoris, is typically due to insufficient blood supply to the heart muscle (myocardium). The condition that it most frequently indicates is coronary artery disease.

Question 3: Write the treatment of Coronary Thrombosis.


Treatment of Coronary Thrombosis:

1. Aspirin can be chewed just before the doctor gets there. Taking aspirin prevents blood clots.
2. Antiplatelet medications to prevent clotting
3. Thrombolytic treatment to dissolve coronary artery clots
4. Procedures to open blocked arteries, such as cardiac catheterization, balloon angioplasty, stent placement, and bypass surgery.

Question 4: In which a disorder of blood clotting occurs.


Coronary Artery Disease (CAD) disorder of the circulatory system causes blood clotting.

Question 5: Write about heart failure.


The term “heart failure” signifies that the heart is inoperable and that nothing can be done. Heart failure is the medical term for an underperforming heart. Congestive heart failure is a specific type of heart failure that requires immediate medical care, even though the fact that the names are occasionally used interchangeably.
