Normal Pregnancy Female Anatomy Stages Conception Childbirth Anatomy

Normal Pregnancy Female Anatomy Stages Conception Childbirth Anatomy Weight gain during pregnancy is caused mainly by: your growing baby. increased amounts of amniotic fluid (the protective liquid within your uterus that surrounds your baby) the increased size of your uterus. the placenta. additional breast tissue. increased blood volume. increased fat storage. The dilation stage is the longest stage of labor and typically takes 6–12 hours. however, it varies widely and may take minutes, hours, or days, depending in part on whether the mother has given birth before; in each subsequent labor, this stage tends to be shorter. figure 28.4.4 28.4. 4: stages of childbirth.

Stages Of Pregnancy Diagram During the development and growth of the fetus inside the womb several anatomical changes occur in the pregnant mother to accommodate the process. these changes are basically attributed to the hormones of pregnancy and mechanical pressure exerted by the enlarging uterus. the changes include: development of placenta. A full term pregnancy lasts approximately 270 days (approximately 38.5 weeks) from conception to birth. because it is easier to remember the first day of the last menstrual period (lmp) than to estimate the date of conception, obstetricians set the due date as 284 days (approximately 40.5 weeks) from the lmp. Physiology. the earliest sign of pregnancy is a missed menstrual period. for sexually active women who are of reproductive age and have regular periods, a period that is ≥ 1 week late is very likely to be due to pregnancy, although other factors can cause secondary amenorrhea. pregnancy is considered to last: 266 days from the time of conception. The gestational age is expressed in completed weeks. the start of the gestation (based on the lnmp) is usually 2 weeks before ovulation, assuming a 28 day regular menstrual cycle. the developmental or fetal age is the age of the conception calculated from the time of implantation, which is 4 to 6 days after ovulation is completed.

Pregnancy is a state of having implanted products of conception located either in the uterus or elsewhere in the body. it ends through either spontaneous or elective abortion or delivery. during this time, the mother’s body goes through immense changes involving all organ systems to sustain the growing fetus. all medical providers must be aware of these alterations present in pregnancy to be. A pregnancy can be multiple gestations, as in the case of twins or triplets. childbirth usually occurs about 38 weeks after conception, or approximately 40 weeks from the start of the last normal menstrual period. pregnancy is divided into three trimesters that roughly approximate specific developmental stages.
