pig anatomy

#1

epiglottis

Prevents food from entering the trachea during swallowing

#2

soft pallete

separating the mouth from the nasal cavity and controlling airflow, preventing food from entering the nasal passages

#3

hard pallete

crucial for feeding, chewing, and vocalization

#4

larynx

Produces sound (voicebox)

#5

treachea

allow air exchange between the lung and the outside

#6

thryriod

Produces hormones necessary for development (T3 & T4)

#7

thymus

Site of maturation of T-cell lymphocytes

#8

cranial vena cava

Carry blood back to the right atrium
