Kidney

• What is the primary function of the kidneys?

  Filter out waste products from blood
• How do kidneys help regulate blood pressure?

  By controlling blood volume and salts
• What do kidneys regulate in the blood?

  Salts and chemicals at the right levels
• What is the role of the nephrons in the kidneys?

  They filter blood and remove waste
• What is the renal cortex?

  • Part of the kidney
  • Mostly consists of nephrons
  • Responsible for filtering blood
• Where are the major blood vessels found in the kidney?

  In the renal medulla
• What do the renal arteries do?

  Take blood with waste to the kidneys
• What is the function of the renal veins?

  Return filtered blood to the body
• How do blood vessels function in the kidneys?

  They remove waste into convoluted tubules
• What do the convoluted tubules form?

  • Join together to form the ureter
  • Transport urine to the bladder
• What happens to urine after it is stored in the bladder?

  It is passed to the urethra for release
• What is a glomerulus?

  A network of capillaries in the nephron
• What is filtered in the Bowman's capsule?

  Small molecules like glucose and urea
• What remains in the blood after filtration in the Bowman's capsule?

  Large substances such as proteins
• What are the main components of the kidney's filtration system?

  • Nephrons: filter blood and remove waste
  • Renal cortex: contains most nephrons
  • Renal medulla: houses major blood vessels
  • Glomerulus: capillary network for filtration
  • Bowman's capsule: where filtration occurs
