Example sentences for: veins
How can you use “veins” in a sentence? Here are some example sentences to help you improve your vocabulary:
The distal 5 cm of the catheter was cut off using sterile scissor and sent aseptically to the clinical microbiology laboratory where it was cultured by semiquantitative method [ 10 ] . When blood cultures were indicated, 10 mL of venous blood was drawn from catheter and from two peripheral veins following skin preparation with povidone-iodine.
Interestingly, however, secondary and tertiary mesenteric veins have almost identical thickness.
Differences in smooth muscle layer thickness, however, do not always satisfactorily explain why in some instances, including stimulation of postganglionic nerve terminals, veins are more responsive than corresponding arteries [ 3 4 5 6 ] . Although differences in the type and amount of neurotransmitters, receptor density and/or sensitivity for neurotransmitter action, or signal transduction mechanisms that couple membrane receptors to the contractile elements have been proposed to underlie the functional distinctions between capacitative and resistive regions of the mesenteric circulation, the possibility that mesenteric artery and vein convey distinct expression levels of contractile proteins has not been ruled out.
It appears, therefore, that descending down the mesenteric tree, the contractile potential of arterial strips would decrease faster relative to that of veins.
It remains to be determined whether the relatively bigger amount of caldesmon and TM-α is advantageous for the artery in fulfilling resistive functions, and whether more TM-β is a prerequisite for veins to fulfill capacitative functions in the mesenteric circulation.
