Biology Flashcards
Ovaries
Store and release eggs
Fallopian tubes
It carries the egg to the uterus, fertilization occurs here
Uterus
The (womb) is where the fertilized egg becomes implanted and finds nourishment
Cervix
The cervix leads from the vagina to the uterus
Vagina
The vagina holds the male penis during sexual intercourse
Ovulation
An egg is released from the ovary an average of every 28 days
Menstruation/Period
The uterus becomes thicker and richer in blood vessels to be ready to receive the egg. If it’s not fertilized by a sperm the thicken uterus breaks away and a small amount of blood passes out through the vagina
Fertile period
These are the days of the menstrual cycle when the woman is most likely to become pregnant
Intercourse 2 or 3 days before, during or after ovulation could lead to fertilization because sperm cells can survive for this long
Pause to menstrual cycle
If an egg is fertilized, the menstrual cycle is paused for the duration of pregnancy. The first sign of pregnancy is often that menstruation does not happen.
Menopause
Signals the end of a female’s ability to reproduce and also the end of her menstrual cycle. It happens at different ages for different people, typically in the late 40’s to early 50’s.
Testes
Produces Sperm
Scrotum
Is where the testes are, it’s located outside the body to ensure the temperature is lower than body temperature for healthy sperm.
Epididymis
Is a coiled tube on the outside of each testis that stores sperm and allows them to mature fully
Vas deferens
Sperm duct
Seminal vesicles, prostate gland and Cowper’s gland
Produces seminal fluid which mixes with sperm to form semen, it nourishes the sperm and allow them to swim.
Penis
It enters female and ejaculates semen
