Study Notes
Pregnancy
- Lasts approximately 40 weeks, divided into three trimesters:
- First trimester (weeks 1-12): fetus develops major organs and body systems
- Second trimester (weeks 13-26): fetus grows and develops rapidly
- Third trimester (weeks 27-40): fetus prepares for birth and grows in size
- Stages of fetal development:
- Embryo (weeks 1-8): major organs and body systems form
- Fetus (weeks 9-40): growth and development of organs and body systems
- Maternal changes during pregnancy:
- Physiological changes: weight gain, breast changes, and hormonal fluctuations
- Anatomical changes: expansion of the uterus and changes in the pelvic region
Childbirth
- Stages of labor:
- First stage: onset of contractions to full dilation of the cervix (average 12-24 hours)
- Second stage: pushing and delivery of the baby (average 1-2 hours)
- Third stage: delivery of the placenta (average 5-30 minutes)
- Types of delivery:
- Vaginal delivery: most common type of delivery
- Cesarean section (C-section): surgical delivery through the abdomen
- Factors influencing childbirth:
- Fetal position and size
- Maternal age and health
- Previous uterine surgeries or complications
Baby Born Outside the Uterus
- Ectopic pregnancy: a pregnancy that develops outside the uterus, typically in the fallopian tube
- Causes and risk factors:
- Previous tubal surgery or infection
- Hormonal imbalances
- Multiple previous pregnancies
- Symptoms:
- Severe abdominal pain
- Vaginal bleeding
- Pelvic pain
- Treatment:
- Medication to stop the growth of the embryo
- Surgery to remove the embryo and repair the fallopian tube
- Complications:
- Rupture of the fallopian tube, leading to internal bleeding
- Infertility due to damage to the fallopian tube
Pregnancy
- Pregnancy lasts approximately 40 weeks, divided into three trimesters:
- First trimester: 12 weeks, fetus develops major organs and body systems
- Second trimester: 14 weeks, fetus grows and develops rapidly
- Third trimester: 14 weeks, fetus prepares for birth and grows in size
- Fetal development stages:
- Embryo (weeks 1-8): major organs and body systems form
- Fetus (weeks 9-40): growth and development of organs and body systems
- Maternal changes during pregnancy:
