Inhalation is a process where you breathe air into the lungs. Inhalation is part of the respiratory process, and this happens repeatedly at any time automatically to support life. Your lungs will expand and contract to supply oxygen to be circulated throughout the body. The lungs will deflate to remove residual or waste substances called carbon dioxide. This Is How Breathing Processes Happen Breathing starts from the nose or mouth. Air can enter the body through the nose or mouth, but it is recommended to use the nose. Furthermore, air enters the throat area called the trachea, and continues to the lungs (bronchi). The process of breathing is assisted by large dome-shaped muscles located under the lungs. This muscle is called a diaphragm, which separates the chest cavity and the abdominal cavity. When you breathe, the diaphragm contracts downward, creating a movement that makes oxygen or air enter the lungs. This process is called inhalation. The opposite actually happens when ...

The excretion system in humans is a system that processes the disposal of residual substances resulting from metabolism. Metabolic waste products consist of carbon dioxide (CO2), water (H20), ammonia (NH3), urea, and bile substances. These metabolic waste products must be removed from the body because they are poisonous and can cause disease. In addition to the lungs, skin and liver, the kidneys are one of the important organs in the excretion system in humans. The kidneys are located on both sides of the spine, precisely in the back of the abdominal cavity, under the rib cage. Kidney is an excretion organ that is shaped like red beans and reddish brown. Humans have a pair of kidneys, which are on the left and right. The right kidney is slightly lower than the left kidney because it is near the liver. Each kidney is about 10-12 cm in size, about the size of a fist. Role of the Kidney in the Excretory System In addition to filtering blood, controlling body fluid balance, and maint...

Agranulocytosis is a term used when bone marrow fails to form granulocytes, a type of white blood cell that helps fight infection. If the body lacks granulocytes, it can cause a person to be more susceptible to infection. Agranulocytosis causes the body to not have enough endurance, and can cause complaints easily due to chronic bacterial infections that often occur in the skin, lungs, throat, and others. Recognize the Causes of Agranulocytosis In general, there are two types of agranulocytosis. The first type is congenital and the second type can be obtained from certain drugs or medical procedures. A study found that about 70% of cases of agranulocytosis are related to the effects of treatment. Among them, antipsychotic drugs such as clozapine, antimalarials, drugs to treat hyperthyroidism, and anti-inflammatory drugs that work to reduce inflammation. In addition, there are several other factors that cause agranulocytosis, including: Impaired bone marrow function Chemotherap...

Yellow nails or often called yellow nail syndrome is a rare condition that affects the nails and toenails. This condition is usually accompanied by respiratory problems and lymphatic system problems accompanied by swelling in the lower limbs. Yellow nail syndrome is also associated with lymphedema (swelling of the hands), pleural effusion (fluid buildup in the lungs), chronic bronchitis, to sinus infections. Yellow nail syndrome can occur to anyone, male or female, but generally occurs in older people, above 50 years. The cause of yellow nail syndrome itself is not known with certainty. But in some cases it was reported that this condition can occur due to hereditary or genetic factors. Problems with the lymphatic system (lymph flow) and lymphedema distichiasis syndrome can also trigger yellow nail syndrome. Yellow nail syndrome can develop on its own or occur in several conditions such as cancer, immunodeficiency, and autoimmune diseases such as rheumatoid arthritis. In addition, ...
