Question

1. the combining forms angi/o- and vaso- all mean:

○ vein
○ valve
○ heart
○ vessel

1. the combining forms that mean \vein\ are:

○ arterio- and vaso-
○ ven/o- and phleb/o-
○ atri/o- and athero-
○ angio- and phlebo-

Explanation:

Question 5

To solve this, we recall medical terminology combining forms. "angi/o-" and "vaso-" both refer to blood vessels (arteries, veins, capillaries). "vein" is too specific (ven/o- or phleb/o- mean vein), "valve" has other combining forms, "heart" is cardio- related. So the correct meaning is vessel.

We analyze each option:

• "arterio-" means artery, "vaso-" means vessel, so first option is wrong.
• "ven/o-" and "phleb/o-" both mean vein (e.g., venipuncture, phlebitis), this matches.
• "atri/o-" is atrium (heart), "athero-" is plaque, wrong.
• "angio-" means vessel, "phlebo-" means vein, but angio- is broader, so second option is correct.

Answer:

D. vessel (assuming the options are labeled A - D as: A. vein, B. valve, C. heart, D. vessel)
