What else can I help you with?
Which transport mechanism causes the respiratory gases to move across the alveolar pulmonary capillary membranes?
Diffusion
What moves across the membranes by osmosis?
Water molecules move across membranes by osmosis, from an area of lower solute concentration to an area of higher solute concentration to achieve equilibrium. This process helps maintain proper balance of fluids inside and outside of cells.
Do proteins move by diffusion across a capillary into the surrounding tissue?
no you dum bass
Can lipid soluble substance move by diffusion across a capillary into the surrounding tissue?
sure it can
What are Passive processes that move substances across membranes?
Diffusion ,osmosis
What passive process that move substances across membranes?
Diffusion ,osmosis
How do larger molecules move across epithelial membranes in capillaries?
by exocytosis and endocytosis
What would happen to a cell if materials could not move across the cell membranes?
it will died
Why is it easier to move materials across membranes down a concentration gradient?
osmotic pressure
How are fluids and electrolytes transported across cell membranes?
Fluids and electrolytes are transported across cell membranes primarily through passive and active transport mechanisms. Passive transport occurs via diffusion and osmosis, allowing substances to move along their concentration gradients without energy expenditure. Active transport, on the other hand, requires energy (usually from ATP) to move ions against their concentration gradients, often utilizing specialized proteins like pumps and channels. Together, these processes maintain cellular homeostasis and regulate essential physiological functions.
When the osmotic pressure in a capillary exceeds the blood pressure in the capillary what is the net movement of fluid?
water and waste will move in capillary . water and waste will move in capillary .
Are membranes selectively permeable if they allow only certain substances to move across them?
False.
