| Definition |
| diploid | Diploid cells contain two sets of chromosomes, inheriting a set of chromosomes from each the mother and the father. In human somatic (body) cells, a full complement of chromosomes is 46 (22 pairs of autosomes and two sex chromosomes). This number is naturally twice the haploid number of 23 chromosomes contained in human eggs (ova) and sperm. Most higher organisms are diploid. Plants may be polyploid, (carrying three or more copies of each chromosome). |
| duodenum | The first, shortest and widest part of the small intestine that in humans is about 10 inches long. Located between the stomach and the jejunum, it extends from the pylorus to theundersurface of the liver where it descends for a variable distance and receives the bile and pancreatic ducts, then bends to the left and finally upward to join the jejunum near the second lumbar vertebra. After food combines with stomach acid they descend into the duodenum where they mix with bile from the gall bladder and digestive juices from the pancreas. Digestive System Illustration; linkhere |
