Study Notes
Male and Female Reproductive Systems
- Sperm carries genetic material (DNA) from male to fertilize the egg.
- Testes produce sperm and testosterone.
- Prostate gland and seminal vesicles produce fluid to nourish sperm.
- Vas deferens transports sperm to the urethra.
- Epididymis is where sperm mature.
- Urethra carries both semen and urine.
- Male hormones (e.g., testosterone) regulate sperm production.
- Ovaries produce ova (eggs) and hormones (estrogen, progesterone).
- Placenta delivers nutrients to the embryo.
- Estrogen and progesterone regulate the menstrual cycle and secondary sex characteristics.
- Fallopian tube is the usual site of fertilization.
- Uterus prepares for implantation and maintains pregnancy.
- Uterus wall thickens, egg is released, and lining breaks down (menstruation).
Menstrual Cycle
- Menstrual cycle is a result of the female body preparing for pregnancy.
- Cycle phases: Menstrual, Follicular, Ovulation, and Luteal.
- Menstruation (1-5 days): Shedding of the uterine lining if pregnancy does not occur.
- Follicular phase (6-13 days): Egg develops and LH surges before ovulation.
- Ovulation (Day 14): Egg release from the ovary.
- Luteal phase (15-28 days): Corpus luteum produces progesterone which maintains the uterine lining.
- Positive feedback loop in childbirth and lactation.
- Negative feedback loop (in menstruation) when pregnancy does not occur.
- Positive feedback loop in ovulation.
Homeostasis
- Homeostasis is the body's process to maintain a stable internal environment.
DNA Structure
- DNA: Deoxyribonucleic acid.
- Nitrogenous bases: Adenine (A), Thymine (T), Guanine (G), Cytosine (C).
- Double-stranded helix.
- DNA stores and transmits genetic information.
- RNA has ribose sugar and uracil (U) instead of thymine.
