The layer of skin underneath the epidermis composed primarily of dense irregular connective tissue

Descemet's membrane
Limiting layer of cornea

Desmosome
Type of cell junction; important juction within epithelial tissue; macula adherens

Distal convoluted tubule
DCT; part of the nephron

DNA
Deoxyribonucleic acid; material which carries the genetic information

Ducts of Bellini
Papillary ducts; large collecting ducts in the nephrons

Dust cell
Phagocytic cell found in the alveoli of the lungs; also called an alveolar macrophage or an alveolar phagocyte

Histology hint from Sarah Bellham: If you are studying histology or involved in health care, you need a medical dictionary. You may as well get one as early in your career as possible to maximize the benefit. I recommend: Stedman's Medical Dictionary or Dorland's Illustrated Medical Dictionary, 30th Edition.
