If something slows an asteroid, it may fall towards the Sun, towards Mars, or towards Jupiter. As both Jupiter and Mars move past the asteroids in their orbits, they may be pulled slightly towards those huge bodies in their orbits. In fact, Phobos and Diemos, the two tiny moons of Mars, may be captured asteroids.
Resistance - is opposition to flow and is a measure of the amount of friction blood encounters as it passes through the vessels. Blood flow (F) is directly proportional to the difference in blood pressure (Î´P) between two points in the circulation, that is, the blood pressure, or hydrostatic pressure, gradient. Thus, when Î´P increases, blood flow speeds up, and when Î´P decreases, blood flow declines.
Whereas, if the vascular resistance increases, the blood flow drops and if the vascular resistance decreases, then blood flow rises. This should make sense because the energy that causes blood to exert pressure against the walls of the blood vessel is the driving force for blood flow.he answer to this question is that to keep the blood flow (Q) stable within a given organ or tissue the body must be able to adjust the vascular resistance (R), up or down, to compensate for the changes in perfusion pressure (P). Remember Q = P/R.
