Statement Part of the nephron
A small blood vessel that brings blood to the glomerulus Afferent arteriole
A small blood vessel that takes blood away from the glomerulus Efferent arteriole
A network of capillaries that surrounds the tubules of the nephron Peritubular capillaries
A cluster of capillaries that filter blood to form urine Glomerulus
A cup-shaped sac that surrounds the glomerulus Bowman's capsule
The first part of the nephron tubule, where most of the reabsorption of nutrients and water takes place Proximal convoluted tubule
The second part of the nephron tubule, where further reabsorption of water and electrolytes takes place Distal convoluted tubule
A U-shaped loop of the nephron tubule, where water and electrolytes are further concentrated or diluted Loop of Henle
The final part of the nephron tubule, where urine is collected before it is excreted Collecting duct
Here is a brief explanation of each part of the nephron:
  • Afferent arteriole: The afferent arteriole is a small blood vessel that brings blood to the glomerulus. The glomerulus is a cluster of capillaries that filter blood to form urine.
  • Efferent arteriole: The efferent arteriole is a small blood vessel that takes blood away from the glomerulus. The efferent arteriole is narrower than the afferent arteriole, which helps to maintain the pressure in the glomerulus and ensure that enough blood is filtered.
  • Peritubular capillaries: The perirenal capillaries are a network of capillaries that surround the tubules of the nephron. The perirenal capillaries reabsorb nutrients and water from the tubules and return them to the bloodstream.
  • Glomerulus: The glomerulus is a cluster of capillaries that filter blood to form urine. The glomerulus is surrounded by Bowman's capsule, which is a cup-shaped sac that collects the filtered fluid.
  • Bowman's capsule: Bowman's capsule is a cup-shaped sac that surrounds the glomerulus. Bowman's capsule collects the filtered fluid from the glomerulus and channels it into the proximal convoluted tubule.
  • Proximal convoluted tubule: The proximal convoluted tubule is the first part of the nephron tubule. The proximal convoluted tubule reabsorbs most of the nutrients and water that were filtered from the blood in the glomerulus.
  • Distal convoluted tubule: The distal convoluted tubule is the second part of the nephron tubule. The distal convoluted tubule reabsorbs further water and electrolytes from the filtered fluid.
  • Loop of Henle: The loop of Henle is a U-shaped loop of the nephron tubule. The loop of Henle helps to concentrate or dilute the urine.
  • Collecting duct: The collecting duct is the final part of the nephron tubule. The collecting duct collects the urine from the distal convoluted tubules and transports it to the bladder.
