Cards

Term
Acids
Definition
Release hydrogen ions in solution
Term
Bases (Alkalis)
Definition
Accept hydrogen ions in solution
Term
pH
Definition

Hydrogen ion concentration of a solution

Normal blood pH 7.35-7.45 (7 neutral)

Term
Volatile Acid
Definition

Can be eliminated from body as a gas

 

Carbonic acid (H2CO3) is the only kind of this

produced in the body

Term
Nonvolatile acids
Definition

All other acids produced in the body

 

Must be metabolized or extcreted in fluid

 

Ex: Lactic acid, hydrochloric acid, phosphoric acid,

sulfuric acid

Term

3 Systems that work together to

maintain normal pH range

Definition
  • Buffer Systems
  • Respiratory Systems
  • Renal Systems
Term
Buffers
Definition

Substances that prevent major changes in pH by releasing hydrogen ions

 

Act within a fraction of a second

 

Limited capacity to maintain pH

 

Bind with(acid) or release(alkaline)

hydrogen ions to balance pH

Term
Body's major buffer systems
Definition
  • Bicarbonate-carbonic acid
  • Phosphate
  • Protein
Term
Acidosis
Definition

pH below 7.35

 

Results from strong acid to extracellular fluid depleting bicarbonate

Term
Alkalosis
Definition

pH above 7.45

 

Adding a strong base depleting carboinc acid as it combines with the base
