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.
R = Î´ P Q {\displaystyle R={\frac {\Delta P}{Q}}}. where R is the pulmonary vascular resistance (fluid resistance), Î´P is the pressure difference across the pulmonary circuit, and Q is the rate of blood flow through it.
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.
