Health Conditions Related to 5 Different Organs in Human Body

Did you know the human body consists of 78 organs, and five are considered the most important for survival? 

The heart, brain, kidneys, liver and lungs are 5 such organs a human can’t live without. If either of these organs stops functioning for even 10 seconds, one cannot survive. Thus, it is always recommended by physicians to eat a healthy and balanced diet, get adequate sleep, exercise regularly and adopt healthy lifestyle habits.

Organs are made of tissues that perform functions in all living beings and collectively form organ systems. We have listed below the list of 78 different organs in the human body:










Nasal Cavity









Adrenal Glands










Spinal Cord

Thymus Gland


Fallopian Tube

Lymph Nodes


Small Intestine




Large Intestine


Salivary Glands




Lymphatic Vessel


Skeletal Musceles


Bone Marrow




Seminal Vesicles


Bulbourethral Glands

Hair Follicle


Pineal Gland

Subcutaneous Tissue




Mammary Glands

Pituitary Gland





Parathyroid Glands

Vestigal Organ

And out of all these organs, we are going to shed some light on the 5 most important organs and the health conditions that come with them.

Health Conditions Related to Heart

Various heart conditions are called heart disease. It is always wise to see your health professional in case of any discomfort in your heart and get an appropriate diagnosis.


Below are the most common heart conditions and their symptoms:

Coronary Heart Disease

The most prevalent heart condition worldwide is coronary heart disease. This occurs when the heart’s blood vessels, the coronary arteries, become narrow or get blockage and can’t dispense enough blood to the heart. This condition can lead to angina or a heart attack and require immediate medical assistance.

For most people, the first hint that they have Coronary Heart Disease is a heart attack and more symptoms like– discomfort or pain in the chest (angina), nausea, lightheadedness, weakness, cold sweat, discomfort or pain in arms or shoulders and breathlessness.

Also, this heart condition can weaken the heart muscle over time, leading to heart failure or a severe condition where the heart fails to pump blood normally.

Heart Failure

Your body fails to get enough blood and oxygen supply when your heart doesn’t pump effectively, and your heart starts developing different symptoms, such as fatigue and breathlessness. And ineffectiveness of the heart eventually leads to heart failure.

Valve Disease

Valves help to regulate blood flow throughout the heart and make it function effectively. If anything goes wrong with the valves, it can increase your heart's workload and strain your heart, leading to symptoms such as shortness of breath, fatigue, swollen ankles, chest pain or palpitations and dizziness.

High Blood Pressure

Another most common condition, high blood pressure or hypertension, is not a disease but a disorder. It can lead to a high risk of developing severe conditions such as strokes, coronary heart disease and heart attacks.

Congenital Heart Conditions

Conginetial heart conditions happen when the heart’s structure has an abnormality or defect while a foetus is developing inside the mother’s womb. Some congenital heart defects could be life-threatening immediately after birth or over time.

Inherited Heart Conditions

The heart conditions passed on through the families are inherited conditions. They are also known as familial or genetic heart conditions. Such conditions can affect people at any age and can also be life-threatening.

Often people succumb to the inherited heart condition abruptly for no obvious reason.

Health Conditions Related to Lungs

When you take a breath, your lungs inhale oxygen and deliver it to the bloodstream. The cells of the human body require oxygen properly to work and grow. During a typical day, a human breathes almost 25,000 times, but people with lung disease have difficulty breathing without the assistance of any breathing apparatus. 


Read through the three types of lung diseases:

Airway Diseases

Airway diseases directly affect the airways (tubes) that supply oxygen and other gases in and out of the lungs. They usually cause a blockage or narrow the airways and lead to airway diseases such as asthma, chronic obstructive pulmonary disease (COPD) and bronchiectasis. People with airway diseases often say they feel obstructive while breathing.

Lung Tissue Diseases

Lung Tissue Diseases affect the structure of lung tissue. Lungs usually fail to expand completely due to scarring or inflammation in the lungs.  Thus, it gets hard for the lungs to take in oxygen and release carbon dioxide. Ones with this disorder say they feel as if they are wearing something tight on the body that is suffocating them. Pulmonary fibrosis and Sarcoidosis are two significant examples of lung tissue disease.

Lung Circulation Diseases

These diseases directly affect the blood vessels in the lungs. The major causes of these diseases are clotting, scarring or inflammation of the blood vessels. Lungs get less abled while inhaling oxygen and exhaling the blood vessels. These diseases also have a direct impact on the heart as an example of a lung circulation disease is pulmonary hypertension. People with these disorders often feel breathless when they tire themselves doing some activity.

Health Conditions Related to Liver

The organ essential for you to digest your food and helps your body to get rid of toxic substances is the liver.  It is about the size of a football and placed just under your rib cage on the right side of your abdomen. Liver diseases can either be genetically inherited or caused by several factors that damage the liver, such as obesity, alcohol and some viruses.


Types of Liver Diseases

Hepatitis A, Hepatitis B, and Hepatitis C

Hepatitis A, B, and C are caused by various viruses. These viruses may cause similar symptoms, but they are different in several ways depending on how they are transmitted and treated. Also, Acute illness is caused by hepatitis A whereas hepatitis B and C could become chronic.

Fatty Liver Disease and Cirrhosis

Fatty liver is also called hepatic steatosis, and it happens when fat builds up in and around the liver. A smaller amount of fat in your liver is normal, but a more than normal amount can become a severe health problem. Conditions that lead to scarring (cirrhosis) can damage the liver, which can lead to a life-threatening condition that is liver.  But early diagnosis can give the liver time to recover from this deadly health condition.

Liver Cancer

Several types of cancer can form in the liver. The most common type of liver cancer is hepatocellular carcinoma, which begins in the primary type of liver cell called hepatocyte. Other types of liver cancer– intrahepatic cholangiocarcinoma and hepatoblastoma, are not much common.

Health Conditions Related to Kidney

Kidneys help regulate your body's pH levels, salt, potassium, and more. Lifestyle habits and genetic factors majorly affect kidney function. Kidneys are most important for a healthy body and life. They are majorly responsible for filtering waste products, excessive water and other toxicities out of the blood. All toxins are stored in the bladder and then pass through urination.


Types of Kidney Diseases

Chronic Kidney Disease

The most common form of kidney disease is chronic kidney disease. It is a long-term condition that hardly improves over time. The common cause of this condition is high blood pressure.

It is considered contagious for the kidneys as it can aggravate the pressure on the glomeruli. Glomeruli are the small blood vessels in the kidneys to clean the blood. The aggravated pressure damages these vessels, and kidney function begins to slacken.

Kidney Stones

Kidney stones are prevalent in most age groups. They occur when minerals and other substances in the blood start to crystallise in the kidneys forming solid masses or stone-like particles.

The common practice of ejecting stones from the body is urination, and they can be extremely painful and cause significant discomfort and problems.

Health Conditions Related to Brain

Your brain controls your entire body and keeps it in check. It helps control your thoughts, memory, speech, and movement and regulates the function of various organs in the body.


A healthy brain allows you to work quickly and accordingly. However, the results can be devastating when there are some health concerns related to the brain.

You lose brain cells when you suffer a stroke, affecting your ability to think clearly and carefully. Brain tumours can highly affect brain function as they press on nerves and weaken your brain.
