Science Q3 (Human Reproductive System)

• Penis - Deposits the sperm into the vagina during mating.
• Scrotum - Hangs behind the penis and contains the testicles. It acts as a climate control system for the testes.
• Testis - Responsible for making testosterone and producing sperm cells.
• Epididymis - A long, coiled tube that rests on the backside of each testicles. It carries, stores, and brings the sperm to maturity.
• Vas deferens - It transports mature sperm to the urethra in preparation for ejaculation.
• Vasectomy - Surgical procedure to cut or seal the tubes that carry a man's sperm to permanently prevent pregnancy.
• Ejaculatory duct - Formed by the fusion of the vas deferens and the seminal vesicles.
• Urethra - Carries urine from the bladder to outside of the body
• Seminal vesicle - Produces a sugar-rich fluid (fructose) that provides sperms with a source of energy and helps with the sperms' motility (ability to move).
• Prostate gland - It is a walnut-like structure with contributes additional fluid to the ejaculate, and help to nourish the sperm.
• Cowper's gland - Also called the bulbourethral gland.
• Cowper's Gland - Produce a clear, slippery fluid that empties directly into the urethra.
• Ovary - Site of oogenesis; produces hormones estrogen and progesterone.
• Fimbriae - Picks up the ovum from the ovary.
• Fallopian tube - Passage from ovary to uterus; site of fertilization.
• Endometrium - Nourishes the embryo; sheds during menstruation.
• Uterus - Site of egg implantation, embryo development.
• Cervix - Muscular opening of the uterus.
• Vagina - Entrance of the penis, also called the birth canal.
• Bulbourethral glands - Also known as Cowpers' glands, they produce pre-ejaculatory fluid or lubricant.
• Females have 2 ovaries, which alternate each month to produce an egg/ovum.
• Ovulation is when one ovary releases an egg into the fallopian tube.
• Puberty refers to physical changes during adolescence, including breast growth, pubic hair, and menstruation.
• Menarche is the first menstrual period, usually occurring between ages 10-16.
