Explain the sexual reproduction between male and female |
| Answer» Sexual reproduction is a general and fundamental mode of reproducing their young ones in animals, humans, and plants. Compared to asexual reproduction, sexual reproduction is lengthy and more complex. An organism that follows sexual reproduction has the specific reproductive organs. Both male and female have a different set of reproductive organs in their respective systems.The male reproductive organs are located in the lower abdomen around the pelvic region. The major function of the male reproductive organs is to deliver sperm for fertilization. The male reproductive system is mainly composed of:\t*******– A small muscular sac-like organ which is located below and behind the *****. It consists of the testes and is mainly involved in maintaining the temperature required for the of sperm production.\tTestes – It is also called as testicles. They are a pair of oval-shaped organs which are mainly responsible for the sperm production and synthesis of testosterone- male hormones.\t*****– It is the primary sexual organ which serves as both reproductive organ as well as excretory organ and used for the purpose of sexual intercourse. It is a cylindrical tube-like organ with a small opening at the top and is extremely sensitive as it becomes vertical when a person is sexually aroused. Semen, containing sperm, is ejaculated from the opening at the top when the person reaches sexual climax.\tUrethra– A narrow tube-like structure that conducts urine and semen from the urinary bladder to the *****.\tVas Deferens– It is a muscular tube that carries mature sperm produced in the testes to the urethra.The female reproductive organs are located near the lateral walls of the pelvic cavity which consists of the following major organs:\tOvaries– They is a pair of organs which are mainly responsible for the production and storage of ovum, or egg, which are the *** gametes in a female.\tUterus– It is commonly known as the womb. It is a pear-shaped muscular bag-like organ with a strong muscular lining that holds the baby after fertilization. The uterus is referred as the site for the embryo development as it protects the fertilized ovum and holds it till the baby is mature enough for birth.\tCervix– A cylinder ring-shaped tissue which is composed mainly of fibromuscular tissue. It is located at the lowermost portion of the uterus and is involved in connecting the uterus and the ******.\t******– – The primary sexual organ which serves as both excretory organ as well as reproductive organ. It is a muscular and tubular part of the female genital tract that opens outside the body and the opening of the ****** is called the vulva, which also includes the ********, *****, and urethra. The ****** connects cervix to the external female body parts and it is the path for ***** during coitus as well as a fetus during delivery. | |
