I carry thoughts at rapid speed, through my axon your commands proceed. What am I?
Neuron
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
I’m red and round, I float with ease, delivering oxygen through arteries.
red blood cell
I churn food into a liquid blend, and send it to your intestine friend.
stomach
I let in light but don’t see at all, I focus the rays both big and small.
Cornea
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
I'm tough, I pull, I’m white as lace—muscles to bones, I hold them in place.
tendon
I push the blood from left to right, through chambers four, both day and night.
heart
I’m the filter with nephrons galore, balancing fluids forevermore
kidney
I’m the lens’s sibling, colored and round, I control how much light gets down.
Iris
I control your balance, posture, and grace, though I’m not the thinker in the brain’s space.
Cerebellum
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
I flow away from the heart with might, thick walls hold pressure tight.
artery
I’m coiled and long, I do the most, absorbing nutrients from your toast.
small intestine
I detect smell, though I’m quite small—olfactory neurons are what I call.
Olfactory Bulb
Though I’m just a gap, I help signals cross—without me, the message is lost.
Synapse
I hold bones tight, no muscle inside—sprain me too far, and I’m torn open wide.
ligament
I return the blood with little force, using valves to stay the course.
vein
I create bile but don’t store it inside, I manage toxins the body can’t hide.
Liver
I sit inside your cochlea shell, turning vibrations into stories to tell.
Organ of Corti
Autonomic and somatic are both parts of me; I carry messages beyond the brain, you see.
peripheral nervous system
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
I monitor pressure in a cuff that you inflate, I’m a vital sign you evaluate.
blood pressure
I'm the last stop before you go, I store your waste until it’s time to show.
Large Intestine
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
