The tendency for turbulent flow is greatest in: (A) image_question, (B) image_question, (C) image_question, (D) image_question
Answer is D. The tendency for turbulent flow is greatest in the aoa. The turbulence of flow depends upon Reynold&;s Number: Reynold&;s Number Type of Blood flow <2000 Laminar 2000-3000 Transitional >4000 Turbulent In the proximal poions of the aoa and pulmonary aery, Reynold&;s Number can rise to several thousand during the rapid phase of the ejection, which causes considerable turbulence due to following High velocity of blood flow Pulsatile nature of the flow Sudden changes in vessel diameter Large vessel diameter Ref: Guyton and Hall 13th edition Pgno: 174
