Kidneys anatomy

Question 1

How to kidneys get blood?

Answer 1

• Kidneys have a constant supply of blood
• The blood enters the kidneys via the renal artery and exits the kidneys via the renal veins

Question 2

How is urine from the kidneys urinated?

Answer 2

• Urine produced in the kidney travels down the ureters and is storred in the bladder until it is urinated via the urethra

Question 3

How do kidneys produce urine and filter blood?

Answer 3

• Kidneys contain millions of structures known as nephrons
• In the nephrons, all small molecules diffuse from the glomerulus into the bowman’s capsule
• Further down the tubule, useful substances are reabsorbed into the blood. This includes almost all glucose and amino acids, some water and ions and no urea
• The fluid left in the tubule is known as urine
