• It refers to the biological organs and structures responsible perpetuation of species, thus prevent its extinction

REPRODUCTIVE SYSTEM

is designed for producing eggs (ova), supporting fertilization, and nurturing the developing offspring during pregnancy (in mammals).

female reproductive system

: This hormone prepares the uterus for pregnancy after ovulation and helps maintain pregnancy if fertilization occurs.

Progesterone

: This hormone regulates the menstrual cycle, affects the development of female secondary sexual characteristics (like breasts and hips), and plays a role in bone health

Estrogen

Is part of the fallopian tube (also called the uterine tube). It is the funnel-shaped opening at the distal end (the farthest end) of the fallopian tube, closest to the ovary. • Its primary role is to catch the egg (ovum) released from the ovary during ovulation and guide it into the fallopian tube for potential fertilization.

INFUNDIBULAR • I

are paired, tubular structures that extend from the upper corners of the uterus toward the ovaries

FALLOPIAN TUBES (OVIDUCT)

Fertilization of the egg by sperm occurs in the

ampulla

is where a fertilized egg implants and develops into a fetus during pregnancy.

uterus

Uterus has two main parts

the body which fetus grow the cervix , the lower part that connects to the vagina.

runs through the cervix, and it is the passage through which menstrual blood exits the uterus and sperm enter during intercourse.

cervical canal

serves as the passage for sperm to enter during mating and also serves as the birth canal during delivery. Female Reproductive system ✔ Passage for Sperm During Mating ✓ Birth Canal During Labor ✔ Menstrual Flow Protection and Defense ✓ Sexual Function

vagina

is the external part of the female reproductive system, including the labia and clitoris, and serves as the opening to the vagina.

vulva

LABIA (MAJOR AND MINOR)

Labia Majora Labia Minora

These are the larger, outer folds of skin that protect the inner structures of the vulva.

Labia Majora

: These are the smaller, inner folds of skin that lie within the labia majora.

Labia Minora

is a highly sensitive organ located at the top of the vulva, where the labia minora meet. It contains a large number of nerve endings, making it a key area for sexual pleasure.

clitoris

is responsible for producing sperm and the hormones necessary for reproduction.

male reproductive system

are the primary reproductive organs responsible for producing sperm (male gametes) and the hormone testosterone, which is responsible for the development of male secondary sexual characteristics and sexual behavior

testes

an external pouch of testes it regulate temperature, necessary for proper sperm production.

scrotum

where sperm are produced through a process called spermatogenesis.

seminiferous tubules

is a coiled tube located on the surface of each testis. It serves as a storage and maturation site for sperm.

epididymis

the epididymis is divided into three parts:

caput, corpus, cauda,

located at the superior (upper) end of the epididymis, adjacent to the testes. Receives sperm from the seminiferous tubules (where sperm are initially produced in the testes)

Caput Epididymidis

The body lies along the side of the testes, between the head and the tail of the epididymis. As sperm move through the body of the epididymis, they continue to mature. They acquire the ability to swim (motility) and undergo biochemical changes that prepare them for fertilization. The body also serves as a site for further storage of sperm, though sperm are still not fully mature in this part. Sperm are stored here for several days and continue to gain functional characteristics necessary for fertilization.

Corpus Epididymidis)

The tail is located at the lower (distal) end of the epididymis primary storage site for mature sperm.

Cauda Epididymidis

is a muscular tube that transports mature sperm from the epididymis to the urethra during ejaculation

vas deferens (or ductus deferens)

s are paired glands that produce a significant portion of the seminal fluid, which nourishes and protects the sperm

seminal vesicle

is a tube that carries urine from the bladder and semen from the reproductive tract to the outside of the body

urethra

is the external organ used for mating (copulation). It is responsible for delivering sperm into the female's reproductive tract during insemination.

penis

The fluid that contains sperm cells (the male gametes) along with various secretions from accessory reproductive glands.

SEMEN

Cattle Bulls typically ejaculate ________ of semen per ejaculation.

5-10 milliliters

Boars have larger ejaculates than bulls, with volumes of per ejaculate

200- 300 milliliters

Sheep and Goats: Rams and bucks typically produce smaller ejaculates, around -----______

1-2 milliliters.

Horses: Stallions produce about ___________of semen.

60-80 milliliters

: Produced in the testes, it is responsible for the development of male sexual characteristics, libido, and sperm production.

Testosterone

These are produced by the pituitary gland and regulate testosterone production and spermatogenesis

Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH)

Secreted by the testes, it inhibits the production of FSH when sperm production is adequate.
