Body Systems and Beyond!
Considered the smallest, fundamental unit of life.
What is a cell?
Often colloquially called the "white of the eye," this structural layer forms the tough protective exterior shell of the eyeball.
What is the sclera?
In a classroom digestion lab modeling the stomach, orange juice serves as a realistic substitute for this critical biological fluid.
What is stomach acid?
Nicknamed the "little brain," this rear region manages complex coordinated movement, body balance, posture, and motor memory
What is the cerebellum?
In a classic hands-on lab using crackers and bananas, this final piece of waste material exits through a hole cut into the bottom of a paper cup (science name only!).
What is stool?
In the hierarchy of life, this specific level is defined as an individual living thing is formed by cooperating organ systems.
What is an organism?
This transparent covering over the iris acts as the very first structure helping to gather and focus incoming light rays
What is the cornea?
This fluid, created by the liver and stored in the gallbladder, mechanically breaks up massive fat droplets
What is bile?
Responsible for basic life support, this primary segment handles fundamental autonomous functions such as breathing rhythm, core blood pressure, and heart rate
What is the brainstem?
When navigating a lab specimen like a sheep brain, a scientist uses this specific term to point directly toward the top of the brain facing the sky.
What is dorsal?
This biological category is defined as a group of similar cells structurally working together to execute a highly specific bodily task
What is a tissue?
This internal crystalline architecture actively alters its physical shape to fine-tune focus by flipping incoming light upside-down onto the rear of the eye
What is the lens?
This thick liquid substance is generated after food blocks are thoroughly churned by the stomach's muscular walls and mixed with gastric acids
What is chyme?
This central bridge of nerve fibers serves as the communication line between the right and left cerebral hemispheres.
What is the corpus callosum?
This anatomical directional phrase based on the Latin word rostrum means "toward the snout/nose of an animal."
What is rostral?
This specific biological tier is defined as a collection of functionally related organs that work together to perform complex, essential bodily tasks.
What is an organ system?
Absent in humans, this shiny blue-green layer gives animals like cows, cats, and dogs a literal "second chance" to capture light for enhanced night vision.
What is the tapetum lucidum?
Millions of these tiny, fingerlike lining structures inside the jejunum and ileum maximize the surface area required to efficiently absorb processed nutrients directly into the bloodstream
What are are villi?
While gray matter is primarily made up of neurons, white matter gets its color from cells that look like insulated cables called this
What are axons?
When opening the back half of the dissected eye, students encounter this thick, clear, gelatinous substance that fills the space between the lens and the retina.
What is the vitreous humor?
Moving past an individual organism, it is the correct hierarchical path spanning from a group of one single species to a broadly classified climate region
What is population, community, ecosystem, and biome?
The circular spot located on the back half of the eye where the retina connects to the optic nerve (also the reason for our blind spot).
What is the optical disc?
The coordinated, wave-like muscular contractions that physically propel ingested bolus or chyme forward through the digestive tract.
What is peristalsis?
Appropriately translated as the "Inner Room," this key dual-lobed gray matter hub acts as the brain's ultimate routing station for incoming sensory data
What is the thalamus?
If a dissection guide asks you to locate a structure residing in the "posterior dorsal" zone of the brain, you would find this lobe in the brain.
What is the parietal lobe?
