In the cross-section of a kidney, there are three main regions that become apparent. The outer region is called the "renal cortex", this is where the capillaries are mainly located. The deeper and darker region, that looks like small pyramids arranged in a semicircle is called the "renal medulla", where the filtering of the blood takes place. The flat, tube-like structure is called the "renal pelvis".

Structure moves up against epiglottis when food is swallowed to prevent passage of food into it.
borishaifa [10]

Answer:

The correct answer is A. The larynx moves up against epiglottis when food is swallowed to prevent passage of food into it.

Explanation:

The epiglottis is a moist, cartilaginous structure that is part of the cartilaginous skeleton of the larynx. It also marks the boundary between the oropharynx and the laryngopharynx. The epiglottis obstructs the passage of the bolus at the time of swallowing preventing it from going to the respiratory system.

Larynx closure occurs when the vestibular and vocal folds approach the midline during swallowing. Occasionally, when you eat very fast, solid foods or liquids can enter the larynx.
