What is The airway from mouth to lungs in a fetal pig?
Trachea
Identify the major organs of the respiratory system in a fetal pig?
The major organs of the respiratory system in a fetal pig include the lungs, trachea, bronchi, and bronchioles. The lungs are the primary organs responsible for gas exchange, while the trachea, bronchi, and bronchioles help to deliver air to and from the lungs.
Pig esophagus different structure from trachea?
The pig esophagus is lined with a stratified squamous epithelium designed for food transport and protection from abrasion, while the trachea is composed of cartilage rings and lined with pseudostratified ciliated columnar epithelium to facilitate air passage and filtration. The esophagus lacks cartilage support, has a mucus-secreting submucosa, and undergoes peristalsis to move food to the stomach, unlike the trachea.
What happens when you push downward on the trachea of a fetal pig?
It depends on how hard you push. The trachea is protected with up to a dozen strong C-shaped rings made out of rigid and strong hyaline cartilage so that it stays open for air to pass through. It would be difficult to close it off without breaking the cartilage, but a severe enough blow could do it, and then you'd need emergency medical treatment.
What is a rostrum of a fetal pig?
the rostrum is the snout of a fetal pig
What keeps the trachea from collapsing in the fetal pig?
The uterus keeps the trachea from collapsing in a fetal pig.
Is the esophagus or the trachea on the dorsal side of the pig?
In a pig, the trachea is located on the ventral side, while the esophagus is positioned dorsal to the trachea. The esophagus runs behind the trachea and is responsible for transporting food from the mouth to the stomach. Thus, the esophagus is dorsal relative to the trachea.
How long is the esophagus in a fetal pig?
The esophagus of a fetal pig, like many organs and body parts, looks very similar to that of a human. It is a long narrow tube, pinkish in color, with cilia lined in the inside (to help push down the food). Click on the link below for pictures of a fetal pig esophagus:

Where is the cardiac sphincter found in the fetal pig?
Controls passive from the esophagus into the stomach.
What organs are found in the thoracic cavity of a fetal pig?
The trachea, heart, lungs, bronchial tubes, thyroid gland, and the larynx are found in the cavity of a fetal pig.
What does the thorax of a fetal pig do?
The thoracic duct of a fetal pig is used to transport food into the stomach. This is present before the development of the esophagus.

What is the function of the epiglottis in a fetal pig?
It has the same function as it does in humans - to prevent food from going into the trachea.
