Body Structure & Directional Terminology - Week 2 Flashcards
Human body
Biggest to smallest
Human organism
Body systems - system/o
Organs (viscer/o, organ/o)
Tissues (hist/o)
Cells (cyt/o, cellul/o)
Energy conversion
Metabolism (meta-)
Anabolism (ana-)
Catabolism (cata-)
Homeostasis broke down
Home/o + -stasis
Metabolism =
Anabolism + catabolism
Cell components

- ribosome
- mitochondrion
Nucleus
Tissues
(Hist/o)
Parenchymal vs stromal
4 types of tissue
-epithelial
-connective
-muscular

Organs
(Organ/o, viscer/o)
Termed viscera (singular viscus)
