The kidneys serve the following essential functions, which is the first and foremost?
They regulate the body's fluid status, electrolyte balance, and acid-base balance
The kidneys produce or activate hormones that are involved in erythrogenesis, Calcium metabolism and the regulation of blood pressure and blood flow
The kidneys are also endocrine organs: they produce renin, the biologically active form of vitamin D, erythropoietin, prostaglandins, and bradykinin
They function as filters, removing metabolic products and toxins from the blood and excreting them in urine
The total number of nephrons in both kidneys is about
800, 000 to 1, 200, 000 nephrons
1, 600, 000 to 2, 400, 000 nephrons
1, 000, 000 to 2, 000, 000 nephrons
800, 000 to 1, 000, 000

21%
20%
-21%
-20%
0.5%
A 28 y/o male was admitted because of fever, temp was noted to be 39 degrees Celsius. If the insensible water loss was calculated to be 700mL/day, under physiologic conditions. In this situation, insensible fluid loss is estimated to be?
700mL
770mL
1400mL
500mL
The podocytes consists of negatively charged GAGs and play a role in preventing leakage of large negatively charged macromolecules
True
False
Mesangial cells of the glomerular capillaries are almost completely surrounded by the glomerular capillaries basement membrane and a layer of podocyte foot processes except in the small regions towards the center of the glomerulus where they have neither basement membrane nor podocytes.
False
True
Filtration occurs towards the mesangial cells at the peripheral portion of the capillary wall which is covered by basement membrane and podocytes.
False
True
The endothelial cells contain large fenestrations 70nm hole that has no restriction to the movement of water and small solutes out of the lumen of the capillary
True
False

True
False
