Chromosomes are structures within each cell that contain your genes. Genes contain the DNA codes that makes us who and what we are. Your body's cells contain 46 chromosomes arranged in 23 pairs. You get one of each pair of chromosomes from your mother and one from your father. Errors in your chromosomes and genes cause a variety of medical conditions.

Meconium is the material that's inside your baby's intestines while still in your womb (an unborn baby is called a fetus). Even though a fetus doesn't eat food, it swallows the amniotic fluid that it floats in. This forms a sticky, dark green material in the fetus's intestines.
Bile is a thick, greenish-yellow digestive fluid made in your liver. It helps your body break down and absorb fat in your diet. Bile is stored in the gallbladder until it's needed in the intestines. Bile travels from the liver and gallbladder to the intestine through tubes called bile ducts.
