The kidneys receive a large amount of blood fluid through the renal arteries. The blood is initially filtered by the glomerulus, which only passes molecules with low molecular weight, and then, when passing through the proximal tubules, Henle's loop and distal tubule, high molecular weight molecules are secreted, and important components for the body return through reabsorption. Considering this information and the content studied, analyze the following statements and mark V for true and F for false:

(I) The podocytes are cells that surround the glomerular capillaries.
(II) Reabsorption occurs mostly for components such as water, proteins, and glucose.
(III) Aldosterone is a type of hormone produced by the cortex of the adrenal gland in the kidneys to stabilize the hydroelectrolytic balance.
(IV) The vasoconstriction of the renal arterioles is due to the activation of alpha-1 receptors in the sympathetic system.
(V) In cases of blood loss from the body, there is a higher renal filtration rate to reduce mean arterial pressure.
