Circulatory, Respiratory, and Excretory Systems Nephron
Filtration Each kidney contains approximately one million filtering
units called nephrons. The renal artery transports nutrients and
wastes to the kidney. Chapter 34 34.3 Excretory System
Slide 7
Circulatory, Respiratory, and Excretory Systems Reabsorption
and the Formation of Urine After the blood is filtered, the
filtrate flows through the loop of Henle and the collecting tubule.
Chapter 34 34.3 Excretory System
Slide 8
Glucose and minerals are reabsorbed back into the capillaries
surrounding the renal tubule.
Slide 9
Urine (urea and water), which is excess fluids and wastes,
leaves the kidneys through ducts called the ureters.
