Presentation Transcript

Objective 1 Organs of the Urinary System

(2) Kidneys which manufacture urine

(2) Ureters which transport urine from the kidneys to the urinary bladder

(1) Urinary bladder that stores urine prior to micturition (elimination)

(1) Urethra that carries urine to the surface of the body


Objective 2 Kidney Anatomy

The retroperitoneal kidneys are covered with three layers of connective tissue:

1. Renal Fascia (Outer) 2. Adipose Capsule 3. Renal Capsule (Inner)


Renal (fibrous) Capsule:

inner layer; thin, transparent, dense irregular connective tissue covering which provides a strong barrier preventing the spread of infections to the kidney; has a minor role in protecting the kidney from physical trauma


Internally, the kidney is divided into a:

Cortex: outer, granular appearing tissue

Medulla: inner region made of renal pyramids

Renal Pelvis: adjacent to the renal hilus



Renal Columns: extensions of cortical tissue that lie between pyramids

Renal papillae: tips of pyramids

Major Calyx: portion of the urine collection system that drains several minor calyces

Minor Calyx: portion of the urine collection system that drains one pyramid


Renal Hilus:

Area where the renal artery, renal vein, ureter and nerves attach to the kidney


Blood Supply

The Renal Artery and Its Branches



Objective 2 Nephrons

Nephron; the functional unit of the kidney; it is a microscopic tubular structure that filters the blood and manufactures urine there are over 1 million nephrons per kidney








Classes of Nephrons

Cortical: almost entirely located in the cortex; represent about 75- 85% of all nephrons; they produce urine

Juxtamedullary located close to the cortical.medullary junction; the loops of Henle dip deeply into the pyramids of the medulla; they represent 15-25% of all nephrons; these nephrons make urine too but, additionally, they are important in the conservation of water
