La aorta se ramifica en arterias que se van haciendo cada vez más finas hasta convertirse en arteriolas que finalmente conducen la sangre a los capilares. Sabiendo que el caudal sanguineo es, para una persona en reposo, de 5 Lmin y que los radios disminuyen desde 10 mm para la aorta a \( 0,008 \mathrm{~mm} \) para los capilares, siendo la sección total de los capilares de aproximadamente \( 2.000 \mathrm{~cm}^{2} \), determinar: a) la velocidad de la sangre en la aorta en mm/s b) el número de capllares c) el caudal en \( 1 / \) min de sangre que pasa por un capilar d) la velocidad de la sangre en un capilar, en mm/s c) la velocidad de la sangre en la aorta y en cada uno de los capilares. RTA \( =265,39 \mathrm{~mm} / \mathrm{s} ; 995222930 \) capilares; \( 5,024 \mathrm{E}-9 \mathrm{~L} / \mathrm{min} \) y \( 0,416 \mathrm{~mm} / \mathrm{s} \)
