Ovarian follicles are the basic units of female reproductive biology. Ovum is developed in these structures in the ovary.Each of them contains a single oocytes (immature ovum or egg cell). These structures are periodically initiated to grow and develop, culminating in ovulation of usually a single competent oocyte in humans.They also consist of granosula cells and theca of follicle.
Epiglottis is structure of the body that hangs down the windpipe. When food is swallowed, the Epiglottis keeps it from entering the lungs. In the absence of Epiglottis a person can choke and cough every time while eating.
Normally, Epiglottis points upwards allowing free passage of air into the trachea and larynx. During eating and swallowing process, the Epiglottis shuts itself thus blocking the opening into the trachea. When the swallowing is done, the Epiglottis opens up again allowing normal breathing.
