10 Questions
What is the function of nephrons in the kidneys?
Filter primary urine through the glomerulus, retaining large blood components, reabsorbing essential substances
How does urine flow from the kidneys to the bladder?
Through the ureters
What are the primary functions of the kidneys?
Filtering blood, regulating fluids, salts, acid-base balance, hormone production, vitamin D production
What is the role of the renal pelvis in kidney structure?
Containing over a million nephrons
How many times a day does the kidney filter blood?
Around 200 times
Where is the renal pelvis located in the kidney structure?
Between the renal cortex and the renal medulla
Which of the following substances is NOT reabsorbed by nephrons in the kidneys?
Urea
What is the primary role of renin produced by the kidneys?
Regulating blood pressure
Which part of the kidney contains over a million nephrons?
Renal cortex
What type of balance do the kidneys play a role in regulating?
Salt-acid balance
Study Notes
- Kidneys are bean-shaped organs located below the diaphragm on each side of the spine.
- The primary blood vessels, the artery and vein, enter the kidneys at the renal pelvis.
- Urine produced in the kidneys flows to the bladder through the ureters.
- The kidney structure consists of the renal cortex, renal medulla, and renal pelvis containing over a million nephrons responsible for various kidney functions.
- Nephrons filter primary urine through the glomerulus, retaining large blood components, and reabsorbing essential substances before excreting around 1.5 liters of urine daily.
- Kidneys act as the body's sewage treatment plant, filtering blood around 200 times a day, regulating fluids, salts, acid-base balance, producing hormones like renin and erythropoietin, and playing a role in vitamin D production.
Learn about the anatomy and functions of the human kidneys, including details on the renal cortex, renal medulla, and nephrons. Explore how kidneys filter blood, regulate fluid balance, produce hormones, and eliminate waste products through urine.
