Aspiration pneumonia refers to pneumonia caused by accidental inhalation (aspiration) of food, drink, or vomit into the lungs. Swallowing difficulties, or conditions such as alcohol intoxication, confusion, or decreased mental alertness, may lead to aspiration pneumonia.
Karyotype is a test to identify and evaluate the size, shape, and number of chromosomes in a sample of body cells. Extra or missing chromosomes, or abnormal positions of chromosome pieces, can cause problems with a person's growth, development, and body functions.
In order for chromosomes to be seen this way, they need to be stained. Once stained, the chromosomes look like strings with light and dark bands, and their picture can be taken. A picture, or chromosome map, of all 46 chromosomes is called a karyotype. The karyotype can help identify abnormalities in the structure or the number of chromosomes. To help identify chromosomes, the pairs have been numbered from 1 to 22, with the 23rd pair labeled X and Y..
