The movement of fluids between cellular compartments involves?
The movement of fluids between cellular compartments involves active transport mechanisms, such as ion pumps and channels, as well as passive transport mechanisms like diffusion and osmosis. Cells need to regulate the movement of fluids to maintain homeostasis and ensure proper function. This movement is crucial for distributing nutrients and signaling molecules, removing waste products, and maintaining proper cellular function.
Define glomerular filtration rate Name and describe the pressures which are effective at the glomerulus under normal conditions and result in glomerular filtration?
Glomerular filtration is a passive process in which hydrostatic pressure forces fluids and solutes through a membraneThe glomerular filtration rate (GFR) is directly proportional to the net filtration pressure and is about 125 ml/min (180 L/day).The glomeruli function as filters. High glomerular blood pressure (55 mm Hg) occurs because the glomeruli are fed and drained by arterioles, and the afferent arterioles are larger in diameter than the efferent arterioles.
Which process describes the pushing of water across the capillary (blood vessel) membrane?
The process that describes the pushing of water across the capillary membrane is called filtration. Filtration occurs due to the pressure difference between the blood inside the capillary (hydrostatic pressure) and the surrounding tissue (osmotic pressure). This pressure gradient forces water and small solutes to move out of the capillary into the surrounding tissue.
Which forces affect the exchange of substances between blood and tissue fluid?
At the proximal end of capillary, you get the fluid out in the tissue fluid due to blood pressure. At the distal end of the capillary, you get back the tissue fluid due to oncotic pressure of the blood proteins.
What are the two forces that combine to produce an electrochemical gradient?
The two forces that combine to produce an electrochemical gradient are the concentration gradient, which is the difference in ion concentration across a membrane, and the electrostatic gradient, which is the difference in charge across a membrane. Together, these forces drive the movement of ions across the membrane.
What forces the fluids through the membraNes in the kidneys?
hydrostatic pressure
What is the name of the pressure that forces fluids from capillaries into extracellular spaces?
Capillary Hydrostatic Pressure
When hydrostatic pressure forces water across a membrane passively the process is called?
It's called Filtration

Process where cell forces out contents through membrane?
osmosis
What are the two forces that are in equilibrium in a star?
Hydrostatic and Equilibrium
Which are the two forces that primarily control capillary fluid exchange?
osmotic and hydrostatic forces
The balance of forces that keeps a star from collapsing is called .?
hydrostatic
What does it mean when your power steering pump forces fluids through the top?
It means its time to take your car to the shop.
What is the force that causes water and solutes to be filtered by the glomerulus?
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.
Molecules within the blood are forced out through the walls of capillaries as a result of osmotic pressure?
false- osmotic pressure draws water in capillaries hydrostatic pressure forces water out
What factor gives forces to fluids?
Pressure
