What is the name of the process by which the blastocyst attaches itself to the wall of the uterus?
The morula becomes hollow and fills with fluid — it is then known as a blastocyst. Near the end of this week, the blastocyst will attach itself to the endometrium, the lining of the uterus. This is called implantation.
What is the attachment of the blastocyst to the uterine wall?
This blastocyst adheres (attaches) to the uterine wall (endometrium) for receiving oxygen and nutrients from the mother. This attachment of blastocyst to the endometrium is called implantation.
What is the process in which the zygote having become a blastocyst attaches to the lining of the uterus?
During fertilization, the sperm and egg unite in one of the fallopian tubes to form a zygote. Then the zygote travels down the fallopian tube, where it becomes a morula. Once it reaches the uterus, the morula becomes a blastocyst. The blastocyst then burrows into the uterine lining — a process called implantation.
What is the process called when a blastocyst attaches to the uterine wall quizlet?
The process by which a blastocyst attaches to the lining of the uterus is called: implantation.
What is the blastocyst?
Three days after fertilization, a normally developing embryo will contain about six to 10 cells. By the fifth or sixth day, the fertilized egg is known as a blastocyst — a rapidly dividing ball of cells. The outer group will become the cells that nourish and protect it.
What hormone is produced by the blastocyst?
The level of human chorionic gonadotropin secreted by the blastocyst during implantation is the factor measured in a pregnancy test. hCG can be measured in both blood and urine to determine whether a woman is pregnant.
When does a zygote become a blastocyst?
The zygote enters the uterus in 3 to 5 days. In the uterus, the cells continue to divide, becoming a hollow ball of cells called a blastocyst. The blastocyst implants in the wall of the uterus about 6 days after fertilization.
What occurs when the blastocyst implants in the fallopian tube?
An ectopic pregnancy happens when a fertilized egg implants outside of the uterus, most commonly in the fallopian tube. The fallopian tube is not made to hold a growing embryo and can’t stretch like a uterus.
Where does the blastocyst implant quizlet?
Blastocyst implants in the uterine wall. Once the blastocyst implants in the uterine wall, this hormone begins to be produced.
