Physiology of ascitis

It is known that in ascites, liver damage usually causes a reduced osmotic pressure, and this results in edema. How does this increase the portal venous pressure?

Kidney regulation of osmolarity and absorption of Na and water

Why is the distal tubule/collecting duct the only place to regulate osmolarity, seeing as we can absorb Na without H20 in the ascending loop? Is it just because the effect of any change in osmolarity earlier in the tubule gets undone (by ADH) in the distal tubule? Or is it because those earlier Na transporters aren't under physiological control?

Plese note the following T/F are extremely misleading. In the following questions, determine whether they are True or False, and explain your reasoning. T/F In a normal person at rest, the part of the respiratory cycle in which no air is flowing through the airways and the respiratory muscles are relaxed is at the end of inspiration, prior to expiration? T/F Infants born prematurely frequently develop respiratory distress syndrome of the newborn because they have too few alveoli to exchange O2AND CO2 efficiently. T/F In the systemic cappillaries, the Partial pressure of 02 OF the erythrocytes is greater than the Partial Pressure 02 of the plasma, causing a shift from oxyhemoglobi... click for more
