Unit 1 Exam Review: Part 2

Body fluid compartment within all the cells of the body and accounts for about 67% of body water (Growth and Metabolism)

Intracellular Fluid

Body fluid compartment which is the fluid portion of blood and accounts for about 7% of body water. Has a greater concentration of protein

Plasma

Body fluid compartment found around and between cells and makes up about 26% of body water.

Interstitial Fluid

Which two fluid compartments make up the extracellular fluid?

Plasma and Interstitial Fluid

Stores and transmits genetic information in the form of DNA

Nucleus

Sites of ribosomal RNA synthesis

Nucleolus

Protein factories of the cell

Ribosomes

Proteins synthesized on the attached ribosomes enter this organelle and are distributed to other organelles or secreted from the cell

Rough ER (endoplasmic reticulum)

Contains enzymes for fatty acid and steroid synthesis, stores and releases CA^2+

Smooth ER

Membrane bound vestibular and tubular structures that assist the Golgi Apparatus with sorting, modifying, and directing vestibular traffic in cells

Endosomes

Break down bacteria and dead cell debris with acid and a variety of digestive enzymes

Lysosomes

 Removes hydrogen from organic molecules including lipids, alcohol, and potentially toxic ingested substances

Peroxisomes

Associated with processes that maintain and change cell shape and movements.

Cytoskeleton
