In which structure are lymphocytes produced?

A. Broad ligament: The broad ligament is a peritoneal fold that supports the uterus and attaches it to the lateral pelvic walls.

B. Adventitia: This is the outer connective tissue layer that supports the uterus but does not suspend it from the pelvic wall.

C. Round ligament: This ligament supports the uterus but primarily connects the uterus to the labia majora and does not suspend it from the lateral pelvic wall.

D. Ovarian fossa: This is a depression in the pelvic cavity that contains the ovaries, but it does not suspend the uterus.

A. Epiglottis: The epiglottis is a leaf-shaped flap of cartilage located at the root of the tongue. It covers the opening of the trachea during swallowing to prevent food and liquids from entering the airway. This function is crucial for protecting the respiratory tract from aspiration.

B. Arytenoids: The arytenoid cartilages are small, paired cartilages that are involved in the movement and tension of the vocal cords but do not cover the opening of the trachea.

C. Thyroid: The thyroid cartilage is the largest cartilage of the larynx and forms the Adam's apple but does not cover the trachea.

D. Cricoid: The cricoid cartilage is located below the thyroid cartilage and is the only complete ring of cartilage around the trachea. While it provides support, it does not cover the opening of the trachea.
