Science reproduction system parts

Cervix

The lower part of the uterus that dilates during childbirth, connecting to the vaginal canal.

Vagina

A stretchy canal that connects the external genitals to the uterus, facilitating intercourse and childbirth.

Uterus

A muscular organ where a fertilized egg implants and grows into a fetus during pregnancy.

Endometrium

The uterus's inner lining that thickens monthly, preparing for a potential pregnancy.

Fallopian tube

The ducts through which eggs travel from the ovaries to the uterus; fertilization usually occurs here.

Ovaries

Glands that produce eggs and hormones (estrogen and progesterone) crucial for reproductive functions.

Penis

The male organ for sexual intercourse and urine expulsion.

Urethra

The tube through which urine exits the body and, in males, carries semen.

Testes

Male reproductive glands that generate sperm and testosterone.

Vas deferens

The tube transporting sperm from the testes to the urethra during ejaculation.

Prostate

A gland that produces seminal fluid, which nourishes and transports sperm.

Bladder

The organ that stores urine until it is expelled.

Epididymis

A coiled tube behind each testis where sperm matures and is stored.

Seminal vesicle

Glands that produce a sugary fluid to nourish sperm as part of semen.

Scrotum

The pouch of skin that houses the testes, regulating their temperature.

Stamen

The male part of a flower, consisting of the anther and filament.

Anther

The part of the stamen that produces and holds pollen, essential for plant reproduction.

Filament

The stalk that supports the anther and positions it for effective pollen dispersal.

Carpel

The female structure of a flower, which includes the ovary, style, and stigma.

Stigma

The part of the carpel that captures pollen and initiates fertilization.

Style

The stalk connecting the stigma to the ovary, guiding pollen tubes.

Ovule

The structure in the ovary that develops into a seed following fertilization.

Petal

The colorful parts of a flower that attract pollinators for reproduction.

Sepal

The outer part of a flower that protects the developing bud.

Copulation

The mating process in which male and female reproductive organs come together.

Pregnancy

The condition of carrying a developing fetus within the uterus.

Fertilisation

The union of sperm and egg, leading to the formation of a zygote.

Asexual reproduction

Reproduction without the involvement of gametes, resulting in genetically identical offspring.

Sexual reproduction

Reproduction involving the fusion of male and female gametes to produce genetically diverse offspring.

Pollen

The fine powder containing male gametes, essential for plant fertilization.

Sperm

The male reproductive cell involved in fertilization.

Hormones

Chemical messengers that regulate various functions in the body, including growth and reproduction.

Placenta

An organ that nourishes the fetus and removes waste products during pregnancy.

Gamete

Reproductive/sex cell.
