large intestine – The last section of the digestive system, where water is absorbed from food and the remaining material is eliminated from the body
Plasma B cell – B cells that release their specific antibodies which then circulate through the body, binding to antigens (pathogens).

Autosomal inheritance – Inheritance of a genetic trait not on a sex chromosome
entropy – A measure of disorder or randomness.
polypeptide – a long chain of several amino acids
IPSC – Induced pluripotent stem cells. Adult stem cells that have been reprogramed to act like blastocyst cells.
Tracheids – the elongated cells of the xylem that provide structure as well as conducting water and minerals
