What is the function human chorionic gonadotropin during pregnancy
Rescues corpus luteum from degeneration until, the 3rd or 4th month of pregnancy
What are the functions of progesterone and estrogen during pregnancy
- maintains endometrium of uterus
- helps prepare mammary glands for lactation
- prepare Mother’s body for birth of the baby
Function of relaxin during pregnancy
- increases flexibility of pubic symphysis
2. Helps dilate uterine cervix during labor
What is the function of the hormone hCS
- helps prepare mammary glands for lactation
- enhances growth by increasing protein synthesis
- decreases glucose use and increases fatty acid use for ATP production
Corticotropin releasing hormone function
- establishes the timing of birth
2. increases secretion of cortisol
What are the steps of the first week of development
1 .fertilization
- cleavage
- morula
- blastocyst
- implantation
What may cause female infertility
Ovarian disease
Obstruction of the uterine tubes
Inadequate body fat
Uterus is not prepared for a fertilized ovum
Male fertility is the inability of the sperm fertilizing the secondary oocyte what are the possible causes of male infertility
Over exposure to x rays and ionizing radiation Infections Toxins Malnutrition Higher -than normal scrotal temperatures
When is intracytoplasmic sperm injection uses
This has been used when infertility is due to imapairments in spermatozoon motility or to the failure of spermatic to develop into spermatazoa
What happens in the procedure of in vitro fertilization
Mother - mother is given FSH soon after menstruation ,so we have several secondary oocytes
When several follicles have reached the appropriate size ,the stimulated follicles and transferred to a solution containing sperm and the oocytes go under fertilization
What is an ectopic pregnancy
It is the development of an embryo or fetus outside the uterine cavity
Where can an ectopic pregnancy occur
Uterine tube ,uterine cervix ,ovaries ,abdominal cavity
What are the signs and symptoms of ectopic pregnancy
One are two missed periods followed by bleeding and acute abdominal and pelvic
How would you treat an ectopic pregnancy
Include surgery or the use of cancer drug called methotrexate (embryonic cells stop dividing and eventually disappear )
What can be detected in the urine 8 days after fertilization
Human chorionic gonadotropin
What is placentation
This is the process of forming the placenta
What forms the fetal portion of the placenta
Chorionic villi of the chorion
What forms the maternal portion of the placenta
Decidua basalis of the endometrium
What do the umbilical arteries carry
Deoxygenated blood from the fetus to the placenta
What does the umbilical vein carry
It carries oxygenated blood to the fetus and the Wharton’s jelly
Describe the maternal cardiovascular changes when a mother is pregnant
Stroke volume goes up Heart rate goes up Cardiac output goes up Blood volume goes up IVC compressions loser venous return and may cause edema
When the mother is pregnant she can experience renal artery compression what can this cause
Renal hypertension
What happens to the today volume during pregnancy
Goes up 30 percent
What happens to the expiratory reserve volume during pregnancy
Goes down by 40 percent
