What is the function of the ventricles?

I'm assuming ventricles of the heart?

I think... (Click to Show Hidden Text)

The ventricle is one of two large chambers of the heart that collect and expel blood received from an atrium towards the peripheral beds within the body and lungs.

Let me know if that is what you were asking. Sorry!

Sorry, I mean ventricles of the brain. (Cardiovascular System isn't a topic this year , but nervous system is).

Yeah that's what I realized.

What is the function of the optic chiasm?

[bhavjain]

What is the function of the optic chiasm?

Answer (Click to Show Hidden Text)

The optic chiasm is where the fibers of the optic nerve partially decussate, specifically the medial fibers of each retina. This allows the left hemisphere of the brain to control the right part of both eyes, and the right hemisphere to control the left part of both eyes. This aids in binocular vision.
