By Marian Diamond | General Human Anatomy Lecture 29 of 36
In this lecture, Professor Diamond wraps up her discussion of the nervous system and moves on to the urinary system, beginning with the kidney. She concludes her discussion of the nervous system by describing the cochlea and diagramming its structure, and she indicates how cilia (hair cells) respond to and transmit information about vibrations in the fluid inside the cochlea. Professor Diamond then diagrams the constituents of the urinary systems: kidneys, ureters, urinary bladder, and urethra. She describes the external structure and location of the kidney in detail and then illustrates the internal structure of the organ. She notes that the kidney is divided into the medulla and cortex, and explains that the fundamental structural and functional unit of the kidney is the nephron. She discusses the structure of the nephron, including the Bowman’s capsule and glomerulus, and describes how this structure serves to filter substances from the blood at a remarkable rate.
