What is the physiology of pregnancy?

pregnancy physiology concerns all physical aspects and changes in the body that occurs during pregnancy. This generally includes all elements of the mother's pregnancy process as well as all phases of fetal development. Physiology of pregnancy can also apply to the birth process.

changes in pregnancy will vary from man to person and the development phase are divided into categories known as the first trimester, the second trimester and the third trimester of pregnancy. The first trimester occurs during the first 12 weeks of pregnancy. One of the common events in the physiology of mothers pregnancy is the morning disease, especially during the first trimester. Morning disease is a common term for nausea that occurs early in the morning. However, not every pregnant woman experiences symptoms of morning illness.

During the first trimester, a pregnant woman can experience tender or sore breasts, constipation or hemorrhoids. Irritability or depression are other symptomsomes many women experience in the early stages of pregnancy. During the second and third trimester it can also occurto frequent urination. Some women experience swollen ankles during pregnancy, although this may be related to other physical problems.

The mother's weight gain is the main aspect of pregnancy physiology. Depending on the female body and height, it can get anywhere from £ 25 to £ 65 (11 to 29 kilograms). A pregnant woman can get up to £ 6 (2.72 kilograms) in body fluid. In the full period, the average fetal weight is generally £ 7 (3.17 kilograms).

The

vital aspect of fetal physiology is the heart rate that increases during the pregnancy stage. In four or five weeks, the human fetus will have an average heart rate of about 100 beats per minute. When the fetus experiences dangerously low heart rate, this condition is known as bradycardia. After the birth of the averagno-born heart rate is approximately 130-135 beats per minute.

pregnancy physiology also refers to changes to which tolies in the main body organs. Changes in the cardiovascular system and the pulmonary system are also examined when studying pregnancy physiology. The gastrointestinal system of many women may also be influenced by the changes that occur during pregnancy.

Many books have been written on pregnancy physiology. Some are in the form of a medical textbook that can be useful for students studying medicine. Other publications include simple instructions for pregnant women who will follow and refer to all phases of pregnancy.
