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.
Make a Karyotype. A karyotype is an organized profile of a person's chromosomes. Two chromosomes specify gender  XX for female and XY for male. The rest are arranged in pairs, numbered 1 through 22, from largest to smallest. This arrangement helps scientists quickly identify chromosomal alterations that may result in a genetic disorder.
