What is the principal method through which acids enter the human body?

Cellular metabolism (chemical reactions inside a cell to maintain life.)
Both ureters open into the bladder via the _____.

Ureteral orifices
The renal tubule is made of:

Three parts: the proximal convoluted tubule (PCT), the loop of Henle, and
the distal convoluted tubule (DCT).
What causes water and solutes to leave the glomerulus?
Give this one a try later!
The afferent arteriole, which is fed by the interlobular artery, is much larger
in diameter than the efferent arteriole. The difference in diameter causes an
extremely high blood pressure in the glomerular capillaries, forcing water
and solutes out of the blood, thus making filtration possible. Water and
solutes leave the glomerulus, enter the glomerular capsule, and
subsequently flow into the renal tubule.
What happens if the GFR is too slow? Too fast?
Give this one a try later!
, If flow is too rapid, needed substances cannot be adequately reabsorbed.
If flow is too slow, nearly all the filtrate is reabsorbed, including most of the
wastes that should be excreted.
Describe the loop of Henle.
Give this one a try later!
The second section is the hairpin loop of Henle. Initially the loop of Henle
has the descending limb followed by the ascending limb. The descending
limb allows water loss and the ascending limb allows salt (NaCl) loss.
What happens to cause hyperventilation? Hypoventilation?
Give this one a try later!
If blood pH begins to fall (becomes more acidic), the respiratory center is
excited, causing hyperventilation. If blood pH begins to rise (become more
alkaline), the respiratory center is depressed, causing hypoventilation.
Describe the structure of the renal corpuscle.
