Kidneys
How many kidneys do we have?
Two.
I go from the urinary bladder to the outside world.
What is the Urethra?
What does homeostasis mean?
Balance.
Blood is under high pressure here and toxins are pushed out of the blood to become filtrates.
What are the glomerulus and bowman's capsule?
triangular shaped regions inside the kidney that contain thousands of nephrons.
What is the medullary pyramids?
What are the functional (working) units of the kidneys?
The nephrons.
We carry urine from the kidneys to the urinary bladder.
What are the ureters?
What chemicals do our kidneys filter out to of our blood to help maintain homeostasis?
Urea, Uric Acid, Creatinine.
This is where salt and water are reabsorbed.
What is the loop of Henle?
When a substance moves from an area of high concentration to an area of low concentration.
What is diffusion?
What are two functions of the kidneys?
Filtering blood and Balancing blood pH.
I can hold up to 16 ounces of urine before it passes through to the urethra.
What is the urinary bladder?
What property of the blood do the kidneys balance with bicarbonate and hydrogen ions?
The pH of blood.
This helps to hold the kidney in place in the abdominal cavity.
What is the adipose capsule?
This is the type of waste that we filter out of our blood.
What is Nitrogenous Waste?
How many nephrons does the average person have per kidney?
What is 1,000,000 (1 million)?
I connect the proximal tubule and the distal tubule of the nephron in mammals and birds. Fish don't have one of me.
What is the loop of Henle?
What process happens to your body fluids in the nephrons to keep your body in balance?
Blood becomes Filtrate becomes Urine.
This is the structure that urine exits the nephron through.
What is the collecting duct?
This is where urine is collected from the Pyramids before leaving the kidney.
What is the major calyx?
Can you live without your kidneys?
No.
I encapsulate (surround) the glomerulus and catch the filtrates that are pushed out of blood.
What is the Bowman's capsule?
What is reabsorbed into the blood after filtration?
Water, Glucose (sugar), salts, and amino acids.
This is where glucose (sugar) and water are reabsorbed in the nephron.
What is the proximal tubule?
These muscles must relax in order for you to release urine from your urinary bladder and urinate.
What are the sphincters?
