What does a physiological study involve
it investigates how living organisms function, typically involves experiments, measurements, and observations at the molecular, cellular, tissue, organ or organism level to understand biological mechanisms.
What are different types of anatomical study?
gross anatomy, microscopic anatomy (histology and cytology), developmental anatomy, comparative anatomy, surface anatomy, pathological anatomy, regional anatomy, systemic anatomy
Knowledge of the structure of body parts helps us understnad the function which one is adequate reprfesentation of that principle

When ionic compounds disolve in water their ions?
dissociate
cations and anions that disscoiate in water are sometimes called
electrolytes
What is an electrolyte
a substance that dissolves in water to produce ions, allowing the solution to conduct electricity, examples include salts, acids, and bases

work best in that range
what molecule is produced as a waste product of the metabolism of glucose by cells?
what qualifies something as an organic compound?
carbon dioxide
what is the difference between biomolecules
carbs used for immediate fuel, lipid is stores fuel, lipid is used for transport, protection, control, and nucleic acid is dna and stuff
glucose is major nutrients for most body cells
it is broken down during cellular respiration to produce atp the molecule that powers cellular activities
glycogen is the stored form of carb for
animal
Rna vs Dna what are sugars found in both
ribose and dioxyribose
what is starch
starch is a type of carbs made up of many glucose molecules linked together. it is a way plants store energy
what is cellulose
not digestiable to humans but it is a type of carb found in the cell walls of plants and it provides structure and support to the plant
the plasma membrane is descibed as being selectively permeable
it means it controls what enters and leaves the cell
vitamin a a fat soluble vitim moves across plasma membrane into the cell by
dissolving into lipid bilayer
four primary tissue types
epithelial, connective, muscle, nervous
what is the mesoderm when it comes to the embryonic layer
is one of the three primary embryonic layers that form during early develoment, it is the middle layer, located between the ectoderm and endoderm. It gives rise to strucutres like muscles, bones, the heart, blood vessels, and kidneys

extracellular matrix
What is a biopsy
youll know it when u see it on the test lmao
Write down ecto, meso, and endoderm and what the difference between each?
ectoderm is outer layer and forms skin hair and nails and the nervous system, mesoderm devlopes muscles, bones, and blood vessels and internal organ, endoderm gives ruse to the lining of the digestive tract,respiratory system, liver, pancreas, and bladder
what seperates epithelial tissue from all the other tissue types
prescense of basement membrane
which of the following is function of epithelial tissues
secretion and absorption of molecules
how do we classify different types of epithelial
shape of the cells and number of types of cell barriers
stratified epithelium
multiple layers
keratinized v non keratinized. where would u see it
karanized(found on outer layer of skin) is a tough protective protein called keratin, non keratinized(mouth, vagina, esophagus)th does not have a lyer or keratin and it is softer and more flexible, and moist
describe epidermis of skin
the epidermis is the outermost layer of skin. its made up of several layers of cells with top layer being made of dead cells filled with kertain. the epidermis is a barrier from harmful things
of organelles in cells which one is most important in secretory epiuthellial cells
golgi
what happens to squamous epithelial if you stretch it too far
could tear, lose their structural integrity, or become misaligned.
