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.
â¢ With increased stroke volume, due to increased venous return and/or increased contractility, there. is an increased cardiac output and increased blood pressure. Page 15. Summary. â¢ Increases in peripheral resistance, blood volume, and cardiac output result in higher blood pressure. Conversely decreases in any of these factors lead to lower blood pressure. â¢ Three main sources of peripheral resistance: Blood vessel diameter, blood viscosity, and total vessel.
