4. The kidneys are made of hundreds of structures called, __________ that filter the blood and form__________, which is waste water and waste solutes. A nephron consists of __________ and associated __________ vessels. The process of urine formation begins with __________ filtration, which filters protein-free filtrate from the __________ capillaries into the glomerular __________. During tubular __________, 100% of the filtered __________, amino acids, and bicarbonate and 50% of __________ is reabsorbed from the __________ tubule back into the __________ capillaries. Lastly, during tubular __________, ions such as H+, and __________ are secreted from the peritubular __________ into the __________. 5. Match the following structures with the correct definition/description. 1. Afferent arteriole ___ 1. Leaky capillary network of a nephron 2. Efferent arteriole ___ 2. The outer portion of the kidney 3. Glomerulus ___ 3. Arterioles that exit the glomerulus 4. Loop of Henle ___ 4. Area of a kidney where newly formed urine collects 5. Renal cortex ___ 5. Arterioles that enter the glomerulus 6. Renal medulla ___ 6. U-shaped portion of a nephron 7. Renal pelvis ___ 7. Inner portion of the kidney made up of renal pyramids

Activity: Complete the Story of the Urinary Flow Pathway Nephron Urethra Loop of Henle Ascending Limb Papillae Pelvis Proximal Convoluted Tubule Bowman's capsule Bladder Distal Convoluted Tubule Descending Limb Collecting Duct Minor/major Calyx Ureter Glomerulus Urine is formed by a specific structure known as the _(1)_. To begin this process, blood enters the renal corpuscle by way of the afferent arteriole and reaches the _(2)_ of the nephron, which is a specialized capillary bed that acts like a strainer to filter out dissolved particles from the plasma. As fluid leaves the glomerulus, it enters _(3)_ and is now known as filtrate. Filtrate quickly moves into the next segment of the nephron, the renal tubule by entering the _(4)_ where 65% of all particles the body needs to keep are reabsorbed into peritubular capillaries. Next, the filtrate moves to the _(5)_, where reabsorption is completed. In the _(6)_ water only is reabsorbed into the vasa recta while in the _(7)_, salt only is actively transported into the medullary space. The last stop for the filtrate is the _(8)_, where secretion occurs. Here waste products can be secreted from the peritubular capillaries and become a component of urine. The last stop in the nephron is the _(9)_, where urine from multiple nephrons merges together. This tube carries the urine to the inferior part of the pyramid known as the _(10)_ where urine drips into a funnel shaped structure known as a _(11)_. Each calyx collects urine from one pyramid and transports the waste into the center of the kidney in an open area known as the _(12)_. This region directs urine out of the kidney via the _(13)_, which exits the hilum. From here, the ureters carry urine for storage in the _(14)_ before it will be released from the body by a final output tube known as the _(15)_.
