The heart, stomach, lungs, pancreas, kidney, gallbladder and brain are a few of the major organs in your body. Some organs are more important than others. For example, you can live with only one kidney and without your gallbladder. Each organ can become diseased if you take certain medications, eat poorly or don't take good care of yourself.
Heart
The heart is one of the most important muscles in your body that beats to keep you alive. It contains many vessels that carry blood. Sometimes, cholesterol can build up in these vessels and cause fluctuating chest pain (angina) or a heart attack (myocardial infarction). Crushing chest pain that leads to arm pain, nausea and sweating (diaphoresis) are just some of the manifestations of a heart attack, says MedlinePlus.
Your heart also contains an intricate electrical conduction system that flows from the top to the of bottom of your heart. Specifically, there are certain points in your heart in which the electric conduction travels. It goes from your sinoatrial node (portion of the upper chamber of your heart) to your atrioventrioventricular node (near the middle of your heart). The electricity then diverts to your purkinje fibers (located in the bottom of your heart). Sometimes, this conduction system is disturbed due to medications and illnesses. This is known as an arrythmia (irregular heartbeat).
Stomach
The stomach serves as a receptacle for your food contents. It adds stomach acid to your food to aid in digestion. Sometimes, this acid moves up to your esophagus and causes a burning sensation. This is a sign of gastroesophageal reflux disease (GERD). MedlinePlus says that continuous stomach acid exposure can cause peptic ulcers along your digestive tract. Peptic ulcer manifestations include nausea, stomach pain and fullness.
Lungs
Your lungs are essential for breathing. The lungs contain blood vessels and bronchi (tube-like structures) that carry oxygen. Your two sets of lungs are divided into different lobes (parts). Your lungs are typically tan in color but become a tarry black if you are a chronic smoker. Tumors may form in your lungs and eventually cause lung cancer. MedlinePlus indicates that lung cancer's manifestations include a chronic and bloody cough, trouble breathing, unintentional weight loss, chest pain, wheezing and bloody sputum.
Other Organs
Other organs in your body include the spleen, pancreas, gallbladder, liver, brain, kidneys, esophagus and intestines. The spleen is responsible for removing old red blood cells. Your pancreas produces hormones, like insulin, to regulate your blood glucose levels. The gallbladder aids in storing fat while the liver helps your body use glucose. The brain is responsible for regulating your mood, personality and body movements. The kidneys filter your blood. Both the esophagus and intestines are involved with food digestion.
