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.
â¢ This question asks you to choose the factors that will decrease the blood pressure. Study Questions on Factors that Affect Blood Pressure: 1. (Page 1.) What are the four main factors affecting blood pressure? 2. (Page 3.) Blood cells and plasma encounter resistance when they contact blood vessel walls. What is this resistance called? 3. (Page 3.)
