Structure and Functions Of Male Reproductive OrgansMale Structure FunctionsReproductiveOrgansPenis Composed of Deposits sperm spongy tissues cells in the vagina and covered by a loose flap of skin called the roreskin which may be removed by circumcision.
Scrotum Small suspended Holds the testicles sac-like structure which contains the testicles (testes).Testicle/Testes Long, tightly coiled Produces the male tube which lies sex cells (sperm) behind each and male sex testicle. hormone (testosterone)Epididymis Sperm duct or Serves as a tube storage for sperm
Vas deferens A group of small Enables the glands around the developed sperm urethra from epididymis to pass throughProstate gland Found at the Produces prostate upper parts of the secretion urethraUrethra A tube which Enables sperms to opens to the leave the penis outside
Structure and Functions Of Female Reproductive Organs Female Reproductive Structure Functions OrgansOvaries Small, oval- shaped Produce the female cells organs at either side of and hormones (estrogen the uterus, just above the and progesterone) pelvic boneUterus (womb) Found at the front of the Nourishes the fertilized lower abdomen and eggs behind the urinary bladderCervix Narrow outer end pf the Stretches open wide uterus enough for the baby to pass through during delivery
Vagina A canal that leads from Enables sperm to enter the uterus to the external and menstrual fluid to opening of the vulva flow outVulva Area around the opening Lubricates; produces of the female urinary and fluids that facilitates the reproductive systems; passage of sperm consists of two-folds of tissue (labia)Fallopian tubes A pair of tubes stretching Directs the egg from the from the ovary to the ovary to the uterus uterus
Respiratory Systems• The parts of the body that help people breath.• Breathing is one of the involuntary actions people do.• Gaseous exchange takes place by inhaling oxygen and exhaling carbon dioxide.•
Respiratory Structure FunctionsOrgansNostrils Opening which Enables air to leads to the enter the nasal nasal cavity cavityPharynx Throat cavity Enables air from the nasal cavity to enter the tracheaTonsils Soft masses of Blocks off lymph tissues harmful microorganisms
Larynx Triangular ridge Produces called the sounds Adam’s apple; contains the vocal cordEpiglottis Leaf-like plate Controls of flexible opening to cartilage larynx
Trachea Tube Enables air to measuring 11.5 get to the lungs; cm long and 2.5 a passageway cm in diameter; also called the wind pipeBronchi Two tubes Enables air to found at lower pass though end of the tracheaBronchioles Network of Allow for the bronchial tubes change of ending in a tiny oxygen and chamber carbon dioxide
Alveoli Air sac Main organ of surrounded by respiration many blood vesselsLungs Sponge like. Filters and Cone-shaped purifies air organs composed of three lobes, separated by pleural membranes
