Capillary Hydrostatic Pressure
Pressure
false- osmotic pressure draws water in capillaries hydrostatic pressure forces water out
hydrostatic pressure
Pressure. Capillaries are small so the force of blood coming from the heart is at greater pressure when it reaches the tiny capillaries. Pressure forces the diffusion of particles in and the osmotic diffusion of substances out (mainly metabolic wastes) to the veins.
Starling's law of the capillaries states that the net filtration = forces favouring filtration vs. forces opposing filtration. These forces include: Tonicity, Blod Hydrostatic Pressure (BHP), Blood Colloid Osmotic Pressure (BCOP), Interstitial Fluid Hydrostatic Pressure (IFHP), Interstitial Fluid Colloidal Pressure (IFCOP) and membrane permeability. Therefore effective filtration pressure (and the application of Starling's Law of the Capillaries) is defined as such: EFP=(BHP + IFCOP) - (IFHP + BCOP) Therefore: BHP + IFCOP moves fluid out of the capillaries and IFHP + BCOP moves fluid into capillaries
filtration
temperature, pressure or added fluids
Hydrostatic pressure. The vessel draining the glomerulus has a smaller internal diameter than the vessel feeding it. This means that blood doesn't exit the glomerulus as quickly as it enters. This creates a pressure, called hydrostatic pressure, within the glomerular capillaries and that pressure forces the fluids and many solutes into the glomerular capsule surrounding the glomerulus.
a. moving molecules that exert forces.
All of the forces exerted by the individual particles in a fluid combine to make up the pressure exerted by the fluid.
The capillaries behind your eyes are very delicate and sensitive to blood pressure changes. Roller coasters can increase the blood pressure in the anterior end of your body (head) through negative g forces ("upwards" forces). Sufficient pressure can rupture capillaries resulting in what is called "red out," where you can actually see red. Brain damage is also a concern for the same reason. BUT THIS WILL NEVER HAPPEN ON ROLLER COASTERS!
air particles push against each other and against the container and these pushes create forces against their container.xD
