Level#1
Nephrons are small tubes that remove extra water, salt, and other waste materials from the blood. Each nephron has a cup-like structure at one end. Inside of this structure, blood flows through the many coiled capillaries where the wastes are removed.
1. What are nephrons?
2. Where is the cup-like structure of the nephron found?
3. What is removed in the many coiled capillaries of cup-like structure of the nephron?
Level#2
Nephrons are small tubes that remove extra water, salt, and other waste materials from the blood. Each nephron has a cup-like structure at one end. Inside of this structure, blood flows through the many coiled capillaries where the wastes are removed. The filtered materials pass into a cup-like structure. Then, nutrients pass from a tubule back into the blood. Extra water, salts, and waste molecules combine to form urine.
1. What do nephrons do?
2. What flows through the nephron?
3. What happens to the nutrients?
Level#3
Nephrons are small tubes that remove extra water, salt, and other waste materials from the blood. Each nephron has a cup-like structure at one end. Inside of this structure, blood flows through the many coiled capillaries where the wastes are removed. The filtered materials pass into a cup-like structure. Then, nutrients pass from a tubule back into the blood. Extra water, salts, and waste molecules combine to form urine. Urine is concentrated in a thin, looped tube. The filtered blood is then returned to the heart in veins. The urine then empties into the last part of the nephron called the collecting duct. Urine flows through ureters to the bladder. It is stored there until it is released through the urethra.
1. What do nephrons do and what goes on inside of the cup-like structure of the nephron?

2. Explain in detail how urine is produced and the steps urine takes in exiting through the urethra.
