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.
Thus hemodynamics explains the physical laws that govern the flow of blood in the blood vessels. Blood flow ensures the transportation of nutrients, hormones, metabolic wastes, O 2 and CO 2 throughout the body to maintain cell-level metabolism, the regulation of the pH, osmotic pressure and temperature of the whole body, and the protection from microbial and mechanical harms.
