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¢ As you go through this topic, keep in mind this flow chart, which outlines the factors affecting blood pressure: Factors Affecting Blood Pressure Peripheral Resistance Vessel Elasticity Blood Volume Cardiac Output Page 2. Goals â¢ To understand the factors that affect peripheral resistance, and therefore blood pressure. â¢ To understand how vessel elasticity, blood volume, and cardiac output affect blood pressure. Page 3. Sources of Peripheral Resistance â¢ One of the main factors that affects blood pressure is peripheral resistance.
