I carry thoughts at rapid speed, through my axon your commands proceed. What am I?

Neuron

100

I give joints shape and keep them light, I'm neither bone nor muscle tight. I cushion blows, and bend with ease—find me in ears and in your knees.

Cartilage

100

I’m red and round, I float with ease, delivering oxygen through arteries.

red blood cell

100

I churn food into a liquid blend, and send it to your intestine friend.

 stomach

100

I let in light but don’t see at all, I focus the rays both big and small.

Cornea

200

I'm the bridge of body and mind, my spinal cord and brain combined. I command and sense, and never rest—this system’s name you must now guess.

central nervous system

200

I'm tough, I pull, I’m white as lace—muscles to bones, I hold them in place.

tendon

200

I push the blood from left to right, through chambers four, both day and night.

heart

200

I’m the filter with nephrons galore, balancing fluids forevermore

kidney

200

I’m the lens’s sibling, colored and round, I control how much light gets down.

Iris

300

I control your balance, posture, and grace, though I’m not the thinker in the brain’s space.

Cerebellum

300

My fibers contract with power and grace, voluntary motion is my place. You flex me to lift, you train me to grow—what kind of tissue makes you go?

skeletal muscle

300

I flow away from the heart with might, thick walls hold pressure tight.

artery

300

I’m coiled and long, I do the most, absorbing nutrients from your toast.

small intestine

300

I detect smell, though I’m quite small—olfactory neurons are what I call.

Olfactory Bulb

400

Though I’m just a gap, I help signals cross—without me, the message is lost.

Synapse

400

I hold bones tight, no muscle inside—sprain me too far, and I’m torn open wide.

ligament

400

I return the blood with little force, using valves to stay the course.

vein

400

 I create bile but don’t store it inside, I manage toxins the body can’t hide.

Liver

400

 I sit inside your cochlea shell, turning vibrations into stories to tell.

Organ of Corti 

500

Autonomic and somatic are both parts of me; I carry messages beyond the brain, you see.

peripheral nervous system

500

I grow with you and store some salt, I fix myself if there's a fault. I'm not soft, but very much alive—what am I?

bone tissue

500

I monitor pressure in a cuff that you inflate, I’m a vital sign you evaluate.

blood pressure

500

I'm the last stop before you go, I store your waste until it’s time to show.

Large Intestine

500

I’m the system that helps you taste,
Five flavors on your tongue are placed.
From savory soups to sweets you crave,
It's signals to your brain I'm brave.
What am I?"

gustatory system
