Nephron Anatomy
his structure of the nephron is responsible for filtering blood and forming the initial filtrate.
What is the glomerulus?
This outer region of the kidney contains the glomeruli and is the site where filtration begins.
What is the renal cortex?
This organ releases renin in response to low blood pressure or low sodium levels.
What is the kidney?
This organ filters blood to remove waste and produce urine.
What is the kidney?
What is the largest organ in the human body?
What is the skin?
This part of the nephron reabsorbs the majority of water, glucose, and ions from the filtrate.
What is the proximal convoluted tubule?
This funnel-shaped structure collects urine from the calyces and channels it into the ureter.
What is the renal pelvis?
This enzyme converts angiotensinogen into angiotensin I.
What is renin?
These two tubes carry urine from the kidneys to the bladder.
What are the ureters?
What structure connects muscles to bones?
What is a tendon?
This U-shaped structure plays a key role in concentrating urine by creating a medullary osmotic gradient.
What is the loop of Henle?
These triangular structures in the inner region of the kidney contain loops of Henle and collecting ducts.
What are renal pyramids?
This structure, primarily found in the lungs, converts angiotensin I into angiotensin II.
What is angiotensin-converting enzyme (ACE)?
This functional unit of the kidney is responsible for filtration, reabsorption, and secretion.
What is the nephron?
What hormone regulates blood glucose levels by lowering it?
What is insulin?
This portion of the nephron is primarily responsible for regulated reabsorption of sodium and secretion of potassium under the influence of hormones like aldosterone.
What is the distal convoluted tubule?
This microscopic functional unit of the kidney is responsible for filtering blood and forming urine.
What is the nephron?
This hormone, released from the adrenal cortex, increases sodium and water reabsorption in the kidneys.
What is aldosterone?
This process in the kidneys removes substances like glucose and ions from the filtrate back into the bloodstream.
What is tubular reabsorption?
What ion is primarily responsible for depolarization during an action potential?
What is sodium (Na⁺)?
This specialized region where the distal convoluted tubule contacts the afferent arteriole helps regulate glomerular filtration rate through tubuloglomerular feedback.
What is the juxtaglomerular apparatus?
This specialized capillary network, located between the afferent and efferent arterioles, is responsible for filtration under high pressure.
What is the glomerulus?
This specific region of the nephron is the primary site where aldosterone acts to increase sodium reabsorption and potassium secretion.
What is the distal convoluted tubule (and collecting duct)?
This hormone increases water reabsorption in the kidneys by acting on the collecting ducts, helping to concentrate urine.
What is antidiuretic hormone (ADH)?
What part of the brain is primarily responsible for balance and coordination?
What is the cerebellum?
