Answer: mouth

To eat food, we must chew before swallowing to prevent choking. The masseter helps us do this. The shape of the masseter is like the shape of a parallelogram. The superficial and deep portions are the two definite parts or sections of the masseter.

Answer: stop bleeding

A synonyom for platelets is thrombocytes. Platelets don't contain a nucleus.

Here is the clotting process:

Usually, we get a cut or something which damages the blood vessel. Our platelets quickly cleave to the blood vessel's edges where it's cut. To get more platelets to come the platelets that first responded to the injury release chemicals. The platelets cast a plug. The external bleeding discontinues. That's it for the exterior but what about the interior?

Fibrin (blood-borne materials) sticks together so it can seal the interior part of the injury.

Men's voices are deeper sounding than women's voices because men's voice boxes are larger. In the larynx there are muscles called vocal cords. When the vocal cords vibrate a sound is made. That is us speaking or making a sound.

Answer: Alfonso Corti

Alfonso Corti was born in 1822. In our ears there is the organ of Corti, which is part of the cochlea. This organ is not found in any animal other than mammals.

When we hear a sound, waves smack the ear drum. The ear drum vibrates and the sound vibrations go through our ossicles. They then go to the cochlea and cause the cochlea's fluid to move. Because the fluid moves our hair cells bend. Our auditory nerve picks up neural signs that our hair cells made. Our auditory nerve then sends signals to our brain. We clarify them as sounds.

Answer: second
