Excretion and Nephron

This blood vessel carries blood to the glomerulus:

• afferent arteriole

• efferent arteriole

• peritubular capillary network

• renal vein

This blood in this vessel is more viscous and has minimal water, nutrients and ions.

• afferent arteriole

• efferent arteriole

• peritubular capillary network

• renal vein

This is a network of capillaries that carries blood at relatively high pressure.

• afferent arteriole

• efferent arteriole

• peritubular capillary network

• glomerulus

This is a network of capillaries that picks up water, ions, and nutrients that have been reabsorbed out of the filtrate.

• afferent arteriole

• efferent arteriole

• peritubular capillary network

• glomerulus

Contains filtrate with lots of water, glucose, amino acids, and ions.

• Bowman's capsule

• proximal convoluted tubule

• distal convoluted tubule

• loop of the nephron

Carries filtrate towards loop of the nephron and has cuboidal cells with microvilli.

• Bowman's capsule

• proximal convoluted tubule

• distal convoluted tubule

• loop of the nephron

Carrier filtrate away from the loop of the nephron towards the collecting duct.

• Bowman's capsule

• proximal convoluted tubule

• distal convoluted tubule

• loop of the nephron

Occurs in glomerulus; seperates blood and filtrate

• pressure filtration

• selective reabsorption

• tubular excretion

• reabsorption of water

high blood pressure causes water & small particles to leave blood, while large components remain

• pressure filtration

• selective reabsorption

• tubular excretion

• reabsorption of water

Active transport of glucose, amino acids from the filtrate into the blood.

• pressure filtration

• selective reabsorption

• tubular excretion

• reabsorption of water
