Do pigs have epiglottis?
Locate the epiglottis, a cone-shaped structure which closes when a pig swallows. The small opening in the center of the epiglottis is the glottis and it leads to the trachea and then to the lungs.
What is the function of glottis?
The glottis, a slit-like opening on the floor of the pharynx, is a valve that controls airflow in and out of the respiratory passages. The glottis opens directly into a boxlike larynx. This voice box occurs in all amphibians but is anatomically most complex in frogs.
What is an epiglottis?
(eh-pih-GLAH-tis) The flap that covers the trachea during swallowing so that food does not enter the lungs.
What is the main function of the epiglottis quizlet?
The main function of the epiglottis is to prevent foods and drinks from falling down the airway. The epiglottis is located at the entrance of the larynx. The opening between the vocal folds is known as glottis and the epiglottis works as a tight seal on the glottis.
What is the function of the sublingual gland in a fetal pig?
The gland is responsible for secreting saliva through the parotid duct into the mouth, which aids in swallowing of food and the beginning of the digestion of starches (you should remember this from lecture). Note: humans also have two parotid glands (one on each side) that are located slightly inferior to the ears.
What is the function of the larynx in a fetal pig?
The larynx (or voice box) is a large hollow structure located at the anterior end of the trachea. Passage of air over vibrating cords of elastic tissue within the larynx produces sound and vocalizations.
What is the function of epiglottis and glottis?
Glottis vs Epiglottis Glottis opens into the windpipe and is responsible for the production of sound. While the epiglottis is a cartilaginous flap on top of the glottis that prevents the food from entering into the larynx.
What is the function of the epiglottis quizlet?
How does epiglottis protect the respiratory system?
The epiglottis is a leaf-shaped flap in the throat that prevents food and water from entering the windpipe and the lungs. It stays open during breathing, allowing air into the larynx.
Which of the following describes the main function of the epiglottis?

What is the function of the epiglottis and the glottis quizlet?
What is the function of hard and soft palate fetal pig?
It is made of bone and covered with folds of mucus membrane. The hard palate separates the oral cavity from the nasal cavities. Note that the membranes continue posteriorly, forming the soft palate, which does not contain bone. It lifts during swallowing to keep food from backing up into your nose.
What is the function of the soft palate in a fetal pig?
This palate is very flexible. When elevated for swallowing and sucking, it completely blocks and separates the nasal cavity and nasal portion of the pharynx from the mouth and the oral part of the pharynx. While elevated, the soft palate creates a vacuum in the oral cavity, which keeps food out.
What is the function of glottis and epiglottis?
What are the functions of the uvula and epiglottis quizlet?
-Epiglottis: a flap of cartilage at the root of the tongue, which is depressed during swallowing to cover the opening of the windpipe. -Uvula: During swallowing, the soft palate and the uvula move together to close off the nasopharynx, and prevent food from entering the nasal cavity.
What is epiglottis and its function quizlet?
epiglottis. A flap of tissue that seals off the windpipe and prevents food from entering. airway obstruction.
What is the function of an epiglottis in a pig?
What is the function of the epiglottis? To cover the trachea during deglutition so food/water does not enter the airway 2 anatomical structures found on female pigs and NOT male
Why do the lungs appear collapsed in the fetal pig?
Lungs appear collapsed in the fetus because they are filled with amniotic fluid and they have never been inflated with air yet. Why is the fetal pig lung tissue so dense? The lungs of a fetal pig have never taken air in so they will appear dense and collapsed.
What is the species for a fetal pig?

How many lungs does a fetal pig have?
The pig’s trunk is divided into two regions: thorax (chest) and abdomen (stomach). Similarly, how many lobes are there in the lungs of the fetal pig? The left lung contains three lobes and the right lung contains four. How are the lungs of a pig divided? The pig lung consists of seven lobes divided by fissures (Figure 10-1). The left side has a cranial, middle, and caudal lobe; the right side has a cranial, middle, and caudal lobe and an intermediate lobe that is located caudal to the heart
