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

Describe the network of blood vessels of the kidney. a. Blood enters and exits the kidney at the renal hilum, and the renal blood supply starts with the branching of the aorta into the renal arteries. They end with the exiting of the renal veins to join the superior vena cava. Each segmental renal artery formed by the splitting of the renal arteries splits again into interlobar arteries and enters the renal columns. These again split to form arcuate arteries, from which cortical radiate arteries radiate out and branch into many afferent arterioles that enter the capillaries supplying the nephrons. Veins trace the path of arteries and have similar names, except there are no segmental veins. b. Blood enters and exits the kidney at the renal hilum, and the renal blood supply starts with the branching of the aorta into the renal arteries. They end with the exiting of the renal veins to join the inferior vena cava. Each segmental renal artery formed by the splitting of the renal arteries splits again into interlobar arteries and enters the renal columns. These again split to form arcuate arteries, from which cortical radiate arteries radiate out and branch into many afferent arterioles that enter the capillaries supplying the nephrons. Veins trace the path of arteries and have similar names, except there are no segmental veins. c. Blood enters and exits the kidney at the renal hilum, and the renal blood supply starts with the branching of the aorta into the renal arteries. They end with the exiting of the renal veins to join the inferior vena cava. Each segmental renal artery formed by the splitting of the renal arteries splits again into interlobar arteries and enters the renal columns. These again split to form cortical radiate arteries that radiate out and branch into many afferent arterioles that enter the capillaries supplying the nephrons. Veins trace the path of arteries and have similar names, except there are no segmental veins. d. Blood enters and exits the kidney at the renal hilum, and the renal blood supply starts with the branching of the aorta into the renal arteries. They end with the exiting of the renal veins to join the inferior vena cava. Each segmental renal artery formed by the splitting of the renal arteries splits again into interlobar arteries and enters the renal columns. These again split to form arcuate arteries, from which cortical radiate arteries radiate out and branch into many afferent arterioles that enter the capillaries supplying the nephrons. Veins trace the path of arteries and have all the same names as the arteries following the same path.
