Reproductive System Flashcards
Which reproductive system is a positive feedback loop?
females, Oxytocin release during childbirth which causes stronger contractions
Which reproductive system is a negative feedback loop?
males, Testosterone regulation in males which inhibits further hormone release when the levels are high
penis function
delivers semen into the female reproductive tract
Vas deferens function
Transports sperm from the epididymis to the urethra.
Seminiferous tubules
Produce sperm within the testes.
Epididymis
Stores and matures sperm.
Testicles (testes)
Produce sperm and testosterone.
Scrotum
Protects and regulates the temperature of the testes.
Prostate gland
Produces fluid that nourishes and protects sperm.
Urethra
Conducts semen (and urine) out of the body
what is meiosis?
creates sex cells with half the number of chromosomes
difference between mitosis and meiosis
mitosis makes identical body cells for growth and repair
meiosis makes sex cells with half the chromosomes for reproduction
whats the difference between spermatogenesis and oogenesis?
Sperma produces sperm continuously in males while oogene produces eggs in females one per menstrual cycle
what is a menstrual cycle?
the monthly process preparing for pregnancy by maturing an egg and thickening the uterus
3 phases of the menstrual cycle?
Follicular- egg matures uterus thickens
Ovulation-egg is released
Luteal-Uterus thickens: if no pregnancy it sheds
Testosterone function and what happens if it malfunctions?
Develops male reproductive organs, sperm production, and secondary sex traits. Malfunction: Low levels cause infertility and reduced male traits.
FSH function and what happens if it malfunctions?
Stimulates sperm production in males and egg development in females. Malfunction: Infertility.
LH function and what happens if it malfunctions?
Triggers testosterone production in males and ovulation in females. Malfunction: Infertility or irregular cycles.
Estrogen function and what happens if it malfunctions?
Develops female traits, regulates cycles, and supports pregnancy. Malfunction: Irregular cycles, infertility.
Progesterone function and what happens if it malfunctions?
Prepares uterus for pregnancy and maintains it. Malfunction: Miscarriage or trouble conceiving.
HcG function and what happens if it malfunctions?
Maintains pregnancy by supporting progesterone. Malfunction: Pregnancy loss.
Oxytocin function and what happens if it malfunctions?
Stimulates labor contractions and milk release. Malfunction: Weak labor or no milk ejection.
Prolactin function and what happens if it malfunctions?
Produces breast milk after childbirth. Malfunction: Lack of milk production.
