Week 1 (Antepartum) Flashcards
Within the male reproductive system, the scrotum hold what and what does it contain?
Scrotum holds testes which contain seminiferous tubules(Where spermatogenesis occurs)
Where is Sperm maturation completed?
Epididymis
After the Epididymis, where does the sperm go?
Through the abdominal cavity and joins the ejaculatory duct
After the ejaculatory duct, what happens to the sperm?
it secretes from the seminal vesicles and passes into the urethra. then out of the body
Prostate glands and bulbourethral gland produce what?
Alkaline fluid as the sperm leaves the body.
In the female body, Where does fertilization occur?
Fertilization occurs in one of the fallopian tubes
Uterus is divided into 3 parts. Explain.
Fundus, body, and cervix
Explain the stages of fertilization
- Sperm Enter the egg
- Blastocyst is created
- Implantation of the blastocyst into uterine cavity (Day 5 or 6)
- Embryo (up to 8 weeks gestation)
- Fetus (9 weeks to birth)
What is a blastocyst?
Consist of the embryoblast in the inner cell and the trophoblast, which assist in implantation and will become apart of the placenta.
What is Organogenesis?
The formation and development of body organs.
With Fetal circulation, weeks 2-3 after conception, what happens?
Cardiovascular system develops
What happens in week 3?
fetal heart begins to beat
What is the ductus venosus?
Connects umbilical vein to inferior vena cava.
What is the Foramen ovale?
Opening between the right and left atria
What is the ductus arteriosus?
Connects the pulmonary artery with descending aorta.
What is the placenta made from?
Maternal and fetal tissue
What is the Chorionic membrane when it comes to the placenta?
Develop from trophoblast and chorionic villi
The chorionic villi later form blood vessels for the fetus
What is the job of the placental membrane?
Prevents fetal and mom blood from mixing.
Allows for gas, nutrient, and electrolyte exchange.
Function of the placenta?
metabolic and gas exchange
Hormone production
How long does it take the placenta to be fully functional?
8-10 weeks
What is the embryonic membranes?
In consist of the amniotic and chorionic membranes which formed the amniotic sac that form around the fetus.
Helps protect the fetus from bacteria and stretches with the fetus as it grows.
In each trimester, how is the amniotic fluid produced?
1st- Amniotic membrane
2nd/3rd- Fetal kidneys
What is the function of amniotic fluid?
Cushions the fetus
Allows for fetal movements
Provide a consistent thermal environment
What does the Umbilical Cord consist of?
AVA
2 arteries and 1 vein
