What are the compensatory mechanisms that are acting to maintain blood pressure in the face of blood loss?
An increase in cardiac output (heart rate x stroke volume) is the main acute compensatory mechanism. There is also constriction of blood vessels to increase total peripheral resistance and maintain central bp. In the more long term, activation of the renin-angiotensin system helps to maintain fluids by reabsorbing sodium and water, releasing aldosterone and promoting thirst. Organs like the liver and the spleen, which act as blood stores, contract to put more blood into circulation. Blood is also diverted away from all systems not considered vital.

How do feedback on mechanisms help maintain homestsasis?
Feedback mechanisms provide information to the body about changes in internal conditions. This information allows the body to respond and make adjustments to maintain balance and stability, which is essential for overall health and function. By sensing fluctuations and acting to correct them, feedback mechanisms ensure that the body can maintain homeostasis despite external or internal challenges.
What is the meaning of pressure in drama?
acting
How can the pressure acting on the surface be increased by the force acting on the surface?
Simply pressure is the force per unit area. So Pressure is directly proportional to the force applied. Hence by increasing the force we can increase the pressure.
How is pressure realted to force and area?
Pressure is the force acting per unit area.
On pneumatic thermostat what is the difference between direct acting and reverse acting?
A Direct Acting (DA) pneumatic thermostat increases branch line pressure as temperature increases. A Reverse Acting (RA) pneumatic thermostat decreases branch line pressure as temperature increases.
What is the differences of direct acting actuator and reverse acting actuator?
When a pressure signal is applied, the valve shaft moves in the direction opposite that of the direct-acting actuator, but it follows the same operating principle. In the reverse-acting actuator, the valve shaft is pulled into the actuator by the application of a pressure control signal.
What is the force per unit area acting on a solid?
pressure
What strain or pressure in a material due to forces acting on it?
Stress
The temperature at which the pressure of the vapor in the liquid is equal to the external pressure acting on the surface of the liquid is a?
Boiling point
2.5 kpa equals how many kgs force?
kPa is pressure, how much area is the pressure acting on
How pressure works in gases?
Pressure in gases is very similar to pressure in liquids. The pressure of a gas is always higher in the direction a force is acting e.g. gravity.
What is the relationship between hydrostatic water pressure and the buoyant force acting on a submerged object?
The hydrostatic water pressure increases with depth, which in turn increases the buoyant force acting on a submerged object.
