Summary Introduction

To discuss:

Normal pH of the blood and ECF, and importance of homeostasis of acid–base balance.

Introduction:

The proper composition and balance of fluid, electrolyte, and acid–base are required to regulate the cellular functions of the body. The urinary, digestive, endocrine, lymphatic, nervous, cardiovascular systems etc. maintain these balances.

Fluid balance: Equal maintenance of fluid gain and loss; and proper distribution of fluid in the body.

Electrolyte balance: Equal maintenance of absorbed electrolytes by the small intestine and loss of electrolytes through urine in the body.

Acid–base balance: Maintenance of the stable body pH.
