Year 11 Excretory system 5D

By Ultimate Bob

Revision of Excretory

This only revision task ONLY focuses on the nephron in brief detail

Some text here about the topic of discussion

Multiple Choice

Site of first filtration

• bowman capsule

• glomerulus

• efferent capillary

• afferent capillary

Multiple Select

What is filtered into the bowman capsule

• water

• small molecules

• blood cells

• large proteins

Multiple Select

Role of proximal convoluted tubule

• Reabsorption of blood cells

• Reabsorption of water

• Reabsorption of amino acid and glucose

• secretion of ammonia

• Reabsorbs ion, amino acid and glucose

• Reabsorbs water (via osmosis) which leads to some urea reabsorbed (which we do not want)

• Ammonia and toxins are secreted (move into the nephron)

Summary

Proximal convoluted tubule

Fill in the Blanks

Open Ended

Provide a description of how water reabsorption is promoted in the loop of henle

Water reabsorption in Loop of Henle

1. Ascending limb pumps out ions (making outer environment of nephron low in water concentration)

2. Water in descending limb moves out via osmosis due to low concentration outside

What common role does the distal convoluted tubule and collecting duct share

Multiple Choice

Nephron in order of filtration

• Bowman, proximal, Loop, distal, collecting duct

• Bowman, distal, Loop, proximal, collecting duct

• Bowman, loop, proximal, distal, collecting duct

• Bowman, proximal, distal, collecting duct, loop
