Science
These introduce bias or variability to results
confounding variables
This tissue lines the surfaces of organs and secretes fluids
epithelial tissue
This plane separates the body into upper and lower halves
transverse plane
Fertilization typically happens here
fallopian tubes
Gives skin strength and flexibility and anchors hair follicles & sebaceous & sweat glands; contains blood vessels, sensory nerve fibers, & piloerector muscles
dermis
positive feedback loop
This word describes tissues without blood vessels
avascular
The heart is ___ to the rib cage
deep
This vessel drains blood directly from the brain
internal jugular vein
partly transparent sheet surrounding the underlying muscles, nerves, and vessels
deep fascia
government agencies (CDC/FDA), "fact checkers", majority consensus
epithelium lining the body cavities, coated in a watery fluid to reduce friction.
bursting of the appendix can cause gut bacteria to spill out into the peritoneal cavity, causing an infection of the peritoneal membrane called...
peritonitis
protein pigment that helps block UV radiation from the sun from damaging DNA of dividing basal cells below
melanin
List the steps of the scientific method in chronological order
Question -> background -> hypothesis -> predictions -> test -> analyze
These structures allow cell contents to flow between adjacent cells
gap junctions
visceral pericardium
Name the structures of the urinary system in order of urine flow
kidneys -> ureter -> urinary bladder -> urethra -> internal/external urethral sphincters
Layers of dead, interlocked keratinocytes that are replaced every month and a half or so. Functions as an extra layer of protection in the epidermis
stratum corneum (surface)
Name the ways corporations and the government may enforce false dominant narratives
Ignore contrary evidence, lie about evidence, smear or falsely label contrary science, scare people
fingerlike extensions of cell membranes that increase surface area
microvilli
bi-layered membrane formed when visceral peritoneum wraps around small intestines and continues back to meet parietal peritoneum. Encloses nerves and vessels going to and form intestines
mesentery
nasal cavity -> pharynx -> larynx -> trachea -> bronchi -> lungs -> alveoli
Briefly describe the process of skin repair after lacerations. Be sure to name specific structures involved.
blood brings macrophages to fight off invading microbes -> blood clotting creates scab -> mast cells trigger inflammation -> fibroblasts reconnect dermis by making dense fibers called scar tissue -> basal cells reestablish the epidermis
