Question

deconstruct the following medical terms into their basic element.

1. passage of a substance through a filter.
2. enzyme that causes vasoconstriction.
3. surrounding the small renal tubules.
4. blood that reclaims previously filtered substances.

Explanation:

1. Filtra- (root: filter) + -tion (suffix: process) = the process of filtering a substance.
2. Vaso- (root: blood vessel) + -constrict- (root: narrow) + -ase (suffix: enzyme) = enzyme that narrows blood vessels.
3. Peri- (prefix: surrounding) + -tubul- (root: small tube/renal tubule) + -ar (suffix: pertaining to) = pertaining to surrounding renal tubules.
4. Re- (prefix: again) + -absorpt- (root: take in) + -ive (suffix: having the quality of) + blood (root) = blood that takes in filtered substances again.

Answer:

1. Filtration: filtra- / -tion
2. Vasoconstrictase: vaso- / -constrict- / -ase
3. Peritubular: peri- / -tubul- / -ar
4. Reabsorptive blood: re- / -absorpt- / -ive / blood
