Maintenance Of Acid-Base Balance

Question 1

To preserve homeostasis the captured hydrogen ion must ultimately be either permanently tied up in

Answer 1

Water molecules, through the removal of carbon dioxide by the lungs, or removed from the body fluids, through secretion by the kidneys.

Question 2

The underlying problem is that the bodies supply of buffer molecules is limited. This situation can be resolved only by

Answer 2

Removing hydrogen ion from the ECF (thereby freeing the buffer molecules), or by replacing the buffer molecules

Question 3

The maintenance of acid base balance includes balancing hydrogen ion gains and losses. This balancing act involves coordinating the actions of

Answer 3

Buffer systems with respiratory mechanisms and renal mechanisms

Question 4

These mechanisms support the buffer system by

Answer 4

1. Secreting or absorbing hydrogen ion
2. Controlling the excretion of acids and bases
3. Generating additional buffers
