HBS 3.4.3Part II day 1

Review Glomerular Filtrate The water, waste products, salt,

glucose, and other chemicals that have been filtered out of the blood at the glomerulus (gloh-mer-yuh-luhs) are known collectively as glomerular filtrate.

The glomerular filtrate consists primarily of water, excess salts (primarily Na+ and K+), glucose, and urea.

Match the amounts: The volume of blood passing through

both kidneys in one minute The amount of glomerular filtrate that

is produced by both kidneys in one minute

the volume of urine that is produced by both kidneys in one minute

the volume of urine produced by an average adult in one day

Let’s take a look at what is really going on inside the Nephron.

Imagine how the 3-D structure of the nephron would appear. For example, the Bowman’s capsule is a cup-like chamber containing the glomerulus. The filtrate that occurs due to high pressure in the glomerulus empties into the Bowman’s capsule and drains into the proximal convoluted tubule. 11:27, 12:30

3.4.3 Procedures 7-10

Use markers or colored pencils to color all vessels containing blood red and all the tubules that would contain filtrate or urine yellow.

Using an orange marker, label the following components of the nephron:› Efferent arteriole› Afferent arteriole› Glomerulus› Bowman’s capsule› Proximal convoluted tubule› Loop of Henle› Distal convoluted tubule› Collecting Duct

o Use a black marker to draw arrows that show the general direction of filtrate and material movement in and out of the nephron’s structural components.o Research the points in the nephron’s structure where the three key processes of filtration, reabsorption and secretion occur. Think about how these three processes relate to the composition of blood and to urine.
