Science- Reproduction Flashcards
Four main hormones that control the menstrual cycle and puberty.
Estrogen
Proesterone
Follicule stimulating hormone
Luteinizing hormone
Male repo system - testes
Produces sperm and testrostrone
MALE REPO system- scrotum
Regulates temerature for sperm and reproduction
Male repo system- penis
Delievers sperm to the inside of the female reproductive system
Male repo system- seminal vesicle
Produces seminal fluid that nourishes sperm
Male repo system- prostate
Produces fluid that helps to protect and transport sperm - fructose is a type of sugar which enegises it giving it energy
FRS- ovary
Ovary: Produces eggs (ova) and hormones (estrogen and progesterone).
FRS- uterus
Uterus: Supports fetal development during pregnancy
RPS- fallopian tube oviduct
Fallopian Tube (Oviduct): Site of fertilization and transports the egg to the uterus.
FRS- cervix
• Cervix: Opens into the uterus and allows passage of sperm and menstrual fluid.
FRS- vagina
Vagina: Birth canal and the receptacle for the penis during intercourse.
FRS-placenta
Provides nutrients and oygen to the fetus and removes waste
FRS- Umbilical cord
Connects the featus to the placenta supplying food and oxygen
Changes During the Menstrual Cycle
Ovary: Follicles mature, ovulation occurs (release of an egg), and the corpus luteum forms.
Uterus: The endometrium thickens in preparation for a potential pregnancy and sheds if fertilization does not occur.
Hormones: Estrogen levels rise before ovulation, followed by a surge in LH; progesterone rises after ovulation.
Body Temperature: Basal body temperature typically rises slightly after ovulation due to increased progesterone.
