As blood passes through the capillary bed in an organ, the capillaries join to form venules (small veins). assume the blood speed increases by a factor of 4.00 and the total cross-sectional area of the venules is 10.0cm2. how many capillaries are involved if their average diameter is 10.0μm?

Explanation:

Given:

factor of increase of blood flow, f = 4

cross-sectional area of venules,

diameter of the capillaries involved in venule formation,

Now, area of each capillary:

No. of capillaries that will combine to form the venule of given cross-section area:

if you already have the answer to (a), then just work out how many periods there are in 1 minute, and that's the answer to (c).

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete
