INDEX

Basically, my topics are Budding in hydra and female reproductive parts . This presentation will be giving you all enough information on both of my topics.

Hydra is exclusively a freshwater organism having different species. It is very small, just a half centimetre long. It is a cnidarian having a tubular body which is composed of a head, distal end and afoot at the end.

budding in hydra

LOREM IPSUM 02

Budding in hydra involves a small bud which is developed from its parent hydra through the repeated mitotic division of its cells. The small bud then receives its nutrition from the parent hydra and grows healthy. Growth starts by developing small tentacles and the mouth. Finally, the small newly produced hydra gets separate from its parent hydra and becomes an independent organism.

The process

The female reproductive system is framed to perform different functions. The female reproductive system is composed of a pair of ovaries along with a pair of fallopian tubes (oviduct) , vagina, cervix, and uterus. These parts along with a pair of mammary glands that are integrated both functionally and structurally also support the process of ovulation,fertilization, birth and finally the child care.

female reproductive organs

Ovaries act as the main female sex organs that produce the female gamete and various hormones. These organs are situated one on both the side of the lower abdomen. Each ovary measures about 2 to 4 cm in length which is then connected to the uterus .

ovaries

It is a muscular, inverted pear-shaped organ of the female reproductive system. The walls of the uterus consist of three layers- the inner glandular layer, the middle thick layer, and the outer thin layer.

Fallopian tubes are a pair of muscular tubes and funnel-shaped structures, extend from the right and left of the superior corners of the uterus to the edge of the ovaries. These tubes are enclosed in small projections called fimbriae that swipe over the ovaries to pick up released ova and deliver them to the infundibulum for supplying the uterus. Each fallopian tube is covered by cilia that functions by carrying the ovum to the uterus.

Fallopian tubes (oviducts)

The vagina is a muscular and elastic tube that connects the cervix to the external body. It functions as the receptacle for the penis in sexual intercourse and delivers sperm to the fallopian tubes and uterus. It also acts as a birth canal by expanding to allow delivery of the fetus during childbirth.

vagina

The cervix is the lower end of the uterus. It is located at the top of the vagina and is about one inch long. The cervical canal passes through the cervix, allowing blood from a menstrual period and a baby (fetus) to pass from the womb (uterus) into the vagina.The cervical canal also allows sperm to pass from the vagina into the uterus
