For physician, particularly for physician who handled pregnant patient in the intensive care unit (ICU) should be familiar 
with the physiologic adaptation of the major organs to the pregnant state. The following article will describe you about the physiology of normal pregnant state in association with how pregnancy may lead the patient into specific condition relating to the ICU.
In this physiology of the normal pregnancy article you will be taken into sections about General changes of pregnant women, The Respiratory changes (with a table which shown changes in lung volumes in women who are 7 to 9 months pregnant compared with volumes in nonpregnant women), Cardiac changes (including a table of central hemodynamic changes in normal pregnancy), Renal changes by 16 weeks gestation, Gastroesophageal reflux common symptom of pregnant women, and physiology of the fetus (figuring maternal–fetal oxygen transfer and table of measurement and value of fetal oxygenation).
Stated in the article, that the knowledge of normal physiology in pregnancy is very important in understanding the pathophysiologic states of women pregnancy.
