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. Slide3
Match the amounts:
The volume of
blood passing through both kidneys in one minuteThe 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 minutethe 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.
http://www.hhmi.org/biointeractive/cardiovascular/kidneyfunction.htmlSlide5
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.

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
GlomerulusBowman’s capsuleProximal convoluted tubuleLoop of HenleDistal convoluted tubuleCollecting Duct
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.
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. Slide8
