Lesson 1
Little boxes in a row
Cuboidal means shaped like a cube. These lining cells are about as tall as they are wide, like sugar cubes lined up in a row.
Each one has a round nucleus right in its middle.
- They line the tiny tubes inside your kidneys.
- They line tubes in many glands, like your sweat glands.
Wow!Your kidneys have about a million tiny filters each, and many of the tubes connected to them are lined with these box cells.
Lesson 2
Take back the good stuff
Cube-shaped cells are thick enough to hold lots of busy cell machinery. That lets them take in things and give out things.
In your kidneys, liquid filtered from your blood flows through tiny tubes. The cube cells grab back the water and useful stuff your body still needs. What is left over becomes pee.
Try thisPress Take back water on the 3D model and watch the cube cells pull useful stuff out of the tube.
