How does lung volume control inspiration?
Nesterboy [21]
An increase in volume DECREASES the pressure in the chest (pressure and volume vary inversely when temperature is held constant -- Boyle's law). Gas can only flow from an area of higher pressure to an area of lower pressure. It can't go uphill -- ever. It can only go from high to low pressure. When the diaphragm and intercostals contract, the diaphragm flattens and the rib cage rises. That increases the volume of the chest. That increase in volume decreases the pressure inside the chest (temperature is held constant -- because the temperature of the chest cavity does not change appreciably. It remains at body temp.). Air then flows from the area of higher pressure (atmospheric) to lower pressure (intrathoracic). That continues until the pressures are equal.

When the diaphragm and intercostals relax, the chest cavity decreases in size, the pressure increases to above atmospheric, and gas flows again from the area of higher pressure (intrathoracic) to lower pressure (atmospheric) until they are again equal.

It has nothing to do with the concentration of oxygen. You can ventilate a lung with ANY gas. It has to do with the change in pressure and only the change in pressure -- which is a function of the volume of the chest cavity.

What makes lipids/fats hydrophobic?
maw [93]

Answer:

Lipids are hydrophobic because they do not mix with water. Lipids are made of long chains of carbon and hydrogen. ... The partial charges on the water molecule cannot interact with the neutral lipid molecule and thus water and lipids do not mix.

The sodium-potassium pump is involved in active transport that moves 3 sodium ions from the cell for every 2 potassium ions it m
Ugo [173]

Answer:

The sodium-potassium pump is an active transporter because it needs to move sodium and potassium ions against the concentration gradient.

Explanation:

You have to think of it as outside vs inside the cell.

Outside the cell, you have 5mM K and 150mM Na. Inside the cell, you have 100mM K and 10mM sodium. Without the transporter then the ions would go from greater concentration to lower concentration.  Energy keeps the ions going from the way they would naturally happen.
