Match the following terms with their definitions:
Tunica = tunic enveloping membrane/layer of tissue Tachycardia = fast heart rate Bradycardia = slow heart rate Asystole = no ventricular contraction 'cardiac arrest'
Match the following cardiovascular terms with their meanings:
Lumen = the cavity or channel within a tube/tubular organ such as a blood vessel or intestine Vaso- = pertaining to or relating to a vessel Tunica = tunic enveloping membrane/layer of tissue Bradycardia = slow heart rate
Pair the terms with their cardiovascular descriptions:
Asystole = no ventricular contraction 'cardiac arrest' Lumen = the space within the blood vessel where the blood flows Vaso- = pertaining to or relating to a vessel Tachycardia = fast heart rate
Match the terminology with their vessel-related associations:
Tunica = tunic enveloping membrane/layer of tissue Vaso- = pertaining to or relating to a vessel Tachycardia = fast heart rate Lumen = the cavity or channel within a tube/tubular organ such as a blood vessel or intestine
Connect the terms with their cardiovascular meanings:
Tachycardia = fast heart rate Tunica = tunic enveloping membrane/layer of tissue Lumen = the space within the blood vessel where the blood flows Asystole = no ventricular contraction 'cardiac arrest'
____ is a fast heart rate
