compartmentalization - #4

Compartmentalization :

the body relies on this to maintain homeostasis in diff area of the body

What often helps with the creation of Compartments?

cells

what tissue is the lining of Organs?

epithelial tissue

what does Basiapical Polarity in Epithelial Cells mean?

this means that there’s MORE nutrients on the side that attaches to the Organ

Basoapical Axis :

an axis where it’s lining is TOUCHING the Organ

Planar Axis :

an axis that RUNS ALONG the Organ

• it’s arrangement can change as we run along this axis

Intracellular Fluid :

also known as “cytosol”

• this makes up MOST of our body fluid

how much Intracellular Fluid makes up all our body fluid?

about half

Extracellular Fluid :

this is all the fluid that SURROUNDS the cells

what does Extracellular Fluid also contain

• Interstitial Fluid

• Plasma

• and Other Fluids

Interstitial Fluid :

this is fluid within a tissue that surrounds the cells

• EX: fat cells (theres a little water/fluid around)

Plasma :

the water with OTHER ions & nutrients within

• EX: blood cells that are suspended in water/fluid

Other Fluids :

this includes CSF & Extracellular Fluid

Why is maintaining fluid in the Extracellular Fluid essential for our bodies to function?

• for our structures to maintain themselves → the fluid builds pressure/structure

• to maintain diff functions within the composition → allowing the functions to differ

an example of maintaining diff fluids to allow for Functions to Differ?

EX: more sodium is stored within the Extracellular Fluid & more potassium is needed in the Intracellular Fluid
