Valve Port

We just learned about the valve Bonnet.

Another part of a valve is the Valve Port.

This is the part of the valve that lets water or gas in or out.
They can have as little as just two ports, but many valves have more.
Some valves even have up to 20 ports!

Simple two port valves are just open or closed.
Other valves with a lot of ports might have a few open and others closed depending on how it is set up.

Lappet

We just learned about the Nerve Net that is like a jellyfish's brain.

Another part of a jellyfish is the Lappet.

The circle shaped bell of a jellyfish is sometimes split up into parts by a small indent on the outside of the bell.
This little part where the bell dips toward the middle helps the jellyfish bell be able to flex and pull in and out so the jellyfish can swim.

Each of the parts of the outside of the bell between the indents is called a lappet.

Zonule of Zinn

We just learned about the Uvea.

Another part of the eye is the Zonule of Zinn.

This are the tiny little things like strings that go from the ciliary body to the lens.
Remember the lens is like the magnifying glass that changes shape so you can see far or close,
and the ciliary body is where the muscles are that help push and pull the lens to change it's shape.

It might sound like someone just wanted to come up with a funny name for a part of the body, but the word "zonule" means like tiny zone or tiny area, and the person who discovered this part of the body was named Johann Gottfried Zinn, so he named the area the Zonules of Zinn.

Sometimes it is also called Zinn's membrane, or the ciliary zonule, but Zonule of Zinn sounds the most fun.

Antarctica

We just learned about the Half Tower, and a whole lot of other types of castle Fortifications.

Let's learn about something else. The continent of Antarctica!

Even though we think of it as just a big chunk of frozen ice at the bottom of the earth, people have studied it and given names to all the parts of it from the east to the west.

There are even seas inside Antarctica, and hundreds of islands!

Some people even live down in Antarctica to study the ice and the climate.
There are some crazy animals down there too living on the land or even deep down in the cold sea.

We are trying to study it and learn more about it every year!

Chacmool

We just learned about the art pattern of Xicalcoliuhqui.

Another ancient Mesoamerican work of art is the Chacmool.

These are sculptures of warriors on their backs, propped up on their elbows with their knees bent and their head turned.
They have a bowl on their stomach, and many people believe these were used to offer sacrifices to mythological gods for fallen warriors.
