BIO 121 Study Guide - Midterm Guide: Renal Pelvis, Renal Calyx, Adipose Tissue
Document Summary
Synthesizes calcitrol active form of vitamin d. Production of urine a fluid waste product containing water, ions, and small compounds. List 8 major functions of the urinary system. List 4 major components of the urinary system. List and describe 3 layers of connective tissue that protect the kidney. Fibrous capsule: layer of collagen fibers that cover the outer surface of the entire organ, maintains shape/position. Perinephrenic fat: layer of adipose tissue around fibrous capsule. Renal fascia: dense outer layer that attaches kidney to muscle and peritoneum. Label the major components of the kidney in a sectional view. Include: cortex, medulla, pyramids, papillae, columns, renal lobes, major calyx, minor calyx, and renal pelvis. Cortex: outer layer in contact with fibrous capsule containing nephrons. Renal medulla: layer deep to cortex, can contain nephrons. Renal lobe: cortex above medulla, a pyramid, and adjacent column. Renal papilla: tip of pyramid that drains into minor calyx. Mino calyx: collecting ducts empty filtrate into this sinus.
