Question

P x 10* m and its length is 103 m. The viscosity Pas. Calculate the capillary resistance. (ii) What will be 5x 10 capillaries connected in a parallel combination? 2-(a) The radius of the aorta is 1.2 x 10 m and the mean pressure is 1 Determine the tension in the aorta wall. aorta is 1.2 x 102 m and the mean pressure is 1.3 x 10* Pa. typical artery is 5.0 x 1o3 m. For a mean pressure of 1.2 x 10' Pa, artery? what would be the tension in the wall of the (e) Using factr the assumption that a ventricle may be approximated by a sphere, by what factor must ventric the wall tension increase to maintain the same pressure difference if the le radius increases by 10%. 3. (a) For the Cardin

Explanation / Answer

a) T= PR
= 13000x0.012 = 156 N  
b) T= PR = 12000x0.005 = 60 N  

c) tension should also increase by 10 % which is 1.1 times
