What is the movement of a fluid through a membrane?

Osmosis is the net movement of water across a selectively permeable membrane driven by a difference in solute concentrations on the two sides of the membrane.

How do liquids across the cell membrane?

Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion (or a type of diffusion known as osmosis ). Osmosis is the diffusion of water across a semi-permeable (or differentially permeable or selectively permeable) membrane.

What is the movement of a solvent across a cell membrane?

Osmosis can be defined as the spontaneous movement of solvent molecules through a semi-permeable membrane from a lower-concentration solution to a higher-concentration solution.

What helps water move across the membrane quicker?

A channel protein, a type of transport protein, acts like a pore in the membrane that lets water molecules or small ions through quickly. Water channel proteins (aquaporins) allow water to diffuse across the membrane at a very fast rate.

What are the different types of transport across the cell membrane?

There are two major types of cell transport: passive transport and active transport. Passive transport requires no energy. It occurs when substances move from areas of higher to lower concentration. Types of passive transport include simple diffusion, osmosis, and facilitated diffusion.

What is the movement of oxygen and carbon dioxide between the alveoli and circulating blood is called?

The process of exchanging oxygen and carbon dioxide between the alveoli and the blood of the capillaries is called: external respiration.

Which oxygen flow meter can be used upright?

pressure-compensated flowmeter

What are the characteristic of alveoli?

Features of the alveoli they have moist, thin walls (just one cell thick) they have a lot of tiny blood vessels called capillaries.
