Filtration and Osmosis Lab

Anatomy 1

Filtration

The process of materials passing through a filter from a region of Higher hydrostatic pressure to a region of Lower Hydrostatic pressure.

What determines which substance can pass through a filter?

The size of the molecule

Can Proteins pass through capillary filtration?

No, because they are very large particles that must be broken down.

Can Amino Acids pass through capillary filtration?

Yes, but they require active transport

Can Water pass through capillary filtration?

Yes, because of osmosis (diffusion of water). It does not require energy and moves in and out of the cells.

Can Red Blood Cells pass through capillary filtration?

No, they cannot pass, they stay where they are supposed to be which are vessels. They carry oxygen to muscle cells then they return to get more.

Do Blood Platelets pass through capillary filtration?

They cannot pass through normally because they go to site of injury and form a clot, so they go to where they are supposed to be

Can White Blood Cells pass through capillary filtration?

They can pass through. They are larger but move in an ameba method through the pores to get to the artery. It helps with infection and add to the cite of infection.

Selectively Permeable

Selective on what moves the membrane (size/polarity)

Semipermeable membrane

A barrier that allows certain molecules or ions to pass through while blocking others.

Diffusion

Passive transport of a molecule from high to low concentration.

Osmosis

Special diffusion H20 from high to low concentration

Facilitated Diffusion

Passive transport of a molecule from high to low with a helper protein.

Active Transport

Movement of a molecule from low to high concertation using ATP

Solute

Minor component of a solution (NaCl, k+) (Substance being dissolved)

Osmosis if the movement of?

fluid/H2O from higher to lower concentration.

Solvent

Major component of a solution (H2O) (The thing that is doing the dissolving)

Solution

Mixture of a solute and solvent

Hypotonic Solution

Less solute and more solvent when compared to another solution

Hypertonic Solution

More solute and less solvent when compared to another solution.

Isotonic Solution

Same solute and same solvent when compared to another solution

Water

Moves from higher to lower solution

Distilled water

Hypo-tonic

Water with 0.9% NaCl

Iso-tonic

5% NaCl

Hyper-tonic
