Whats the primary function of the Respiratory System? allow lungs to take oxygen and dispose of waste products through inhaling and exhaling.
What is the function of the respiratory system of a pig?
The main role of the respiratory system is to capture oxygen from the air as well as to eliminate CO2 from tissue catabolism. In the pig, it also plays an important role in the thermoregulation process, as the pig does not have developed sweat glands.
What is the role of the respiratory system in a healthy functioning of the fetal pig?
The respiratory tract humidifies and warms the air, it also filters out dust particles and germs.
How do fetal pigs breathe?
When breathing, air passes through the nasal passages to the pharynx. The pharynx is the space in the posterior portion of the mouth that both food and air pass through. From the pharynx, it passes through the glottis to the trachea.
What takes over the function of lungs in a fetal pig?
The lungs do not function in a fetal pig. … The placenta takes over the lungs’ function. The fetus’s deoxygenated blood flows to the placenta, where carbon dioxide is removed from the blood, and oxygen is added. The oxygenated blood then returns to the fetus.
Does the diaphragm function in the fetus of a fetal pig?
The diaphragm isn’t used by the fetal pig because gas exchange occurs through the umbilical cord. The diaphragm in adult pigs moves up and down changing air pressure in the chest cavity causing air to move into and out of the lungs.

What function do the cartilaginous rings of the trachea serve in a fetal pig?
Explanation: The trachea maintains its rigidity by virtue of a series of cartilaginous rings arranged along its length called as the C- shaped cartilage rings. They prevent the trachea from collapsing during absence of air and also protect it.
What is the function of the diaphragm?
It is a large, dome-shaped muscle that contracts rhythmically and continually, and most of the time, involuntarily. Upon inhalation, the diaphragm contracts and flattens and the chest cavity enlarges. This contraction creates a vacuum, which pulls air into the lungs.
What does the trachea do?
Your trachea, or windpipe, is one part of your airway system. Airways are pipes that carry oxygen-rich air to your lungs. They also carry carbon dioxide, a waste gas, out of your lungs. When you inhale, air travels from your nose, through your larynx, and down your windpipe.
What is the function alveoli?
The alveoli are where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and breathing out. Oxygen breathed in from the air passes through the alveoli and into the blood and travels to the tissues throughout the body.
What are the respiratory organs of a pig?
The respiratory tract can be divided into the upper part, consisting of the nose, pharynx, larynx and trachea, and the lower part, consisting of the different parts of the lung.
What is the lungs of pig?
The pig lung has the dorsal, ventral, medial and lateral bronchiole systems on either side. In addition, a tracheal bronchiole (bronchus) arises from the right side of the trachea.
What is the function of the hard palate in a fetal pig?
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 does the diaphragm do to help the pig inhale?
contraction of the diaphragm allows chest or thorax cavity to expand.
What is the main function of the tracheal rings quizlet?
The tracheal rings are composed of hyaline cartilage, and their function is to prevent collapse of the respiratory airway.
What is the function of the cartilaginous rings in the trachea quizlet?
What is the function of the cartilaginous rings in the tracheal wall? To prevent the trachea from collapsing, blocking the airway, &, allows the esophagus to expand as food moves through it on the way to the stomach.
What is the purpose of the cartilage rings in the trachea quizlet?
What important role is played by the cartilage rings that reinforce the trachea? It prevents the airway from collapsing during pressure changes of breathing.
What is the function of ribs and diaphragm in breathing?
During inhalation, the ribs move up and outward and the diaphragm moves in. this movement decrease the space in our chest cavity and the air rushes in. During exhalation, the ribs moves down and inward and the diaphragm moves up. This movement increases the space in our chest cavity and the air is pushed out.
Which of the following is the function of the respiratory system?
The lungs and respiratory system allow us to breathe. They bring oxygen into our bodies (called inspiration, or inhalation) and send carbon dioxide out (called expiration, or exhalation). This exchange of oxygen and carbon dioxide is called respiration.
What are the 3 main structures of the respiratory system?
There are 3 major parts of the respiratory system: the airway, the lungs, and the muscles of respiration. The airway, which includes the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles, carries air between the lungs and the body’s exterior. The lungs Continue Scrolling To Read More Below…
What is the function of the cilia or pilli in the trachea?
The function of cilia in the trachea and bronchi is to protect the airways from being damaged or infected by particles of dust or foreign matter.
What happens when exhale?
When the lungs exhale, the diaphragm relaxes, and the volume of the thoracic cavity decreases, while the pressure within it increases. As a result, the lungs contract and air is forced out.
What is the function of the cilia found in the cells of the trachea?
The cilia project into the channel (lumen) of the trachea to trap particles. There are also cells and ducts in the mucous membrane that secrete mucus droplets and water molecules.
What are the three functions of the lungs?
Delivers oxygen to the cells in your body. Removes waste gases, including carbon dioxide, from the body when you exhale. Protects your airways from harmful substances and irritants.
How does circulatory system and respiratory system work together?
The respiratory system works with the circulatory system to provide this oxygen and to remove the waste products of metabolism. It also helps to regulate pH of the blood. … The blood transports the gases to and from the tissue cells. The exchange of gases between the blood and tissue cells is internal respiration.
What is the main organ of the respiratory system?
The main organ of the respiratory system is the lungs. Other respiratory organs include the nose, the trachea and the breathing muscles (the diaphragm and the intercostal muscles).
What do fetal pigs lungs feel like?
The lungs feel spongy because there are millions of alveoli in the lungs. These alveoli are made so that the maximum surface area can take in oxygen for deoxygenated blood. Because there are little spaces between the alveoli, they do not make a solid feeling organ, they make a spongy feeling one.
What is the function of the hard and soft palate of the mouth?
The soft palate is continuous with the hard palate, which forms in the anterior roof of the mouth. The soft palate plays an essential role in blocking food and other substances from entering the nasal passages during swallowing and is important in the formation of certain sounds in speech production.
What is the function of the hard palate quizlet?
The hard palate holds the roots of the teeth and helps with mastication.
What is the function of the soft palate in a 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 the umbilical arteries in a fetal pig?
umbilical arteries: two arteries, carry deoxygenated blood from fetus to placenta.
What is the structure and function of the trachea and the tracheal rings quizlet?
The trachea contains C-shaped tracheal cartilaginous rings (hyaline cartilage), which prevent it from collapsing in the thoracic cavity.
What is the function of trachea filters air we breathe quizlet?
The trachea filters the air we breathe and branches into the bronchi. When a person breathes, air comes in through the nose or mouth and then goes into the trachea (windpipe). From there, it passes through the bronchial tubes, which are in the lungs. These tubes let air in and out of your lungs, so you can breathe.
What are 3 functions of the nasal cavity?
The nasal cavity functions to humidify, warm, filter, and act as a conduit for inspired air, as well as protect the respiratory tract through the use of the mucociliary system. The nasal cavity also houses the receptors responsible for olfaction.
What is the specific function of the cilia on the walls of the trachea quizlet?
What is the specific protective function of the cilia in the trachea? Ciliated cells of the mucosa move the sheet of contaminated mucus away from the lungs and toward the throat for swallowing.
What is the function of the mucous membrane that lines the nasal cavity quizlet?
What are the functions of the mucous membrane that lines the nasal cavity? to warm the air, to moisten the air, and to trap small particles entering the nasal cavity.
What are the 3 functions of the pharynx?
What does the pharynx do?
- Carries air to the respiratory system.
- Delivers food and liquid to the digestive system.
- Pushes food into the esophagus so it’s not breathed in.
- Equalizes pressure in the ears and drains fluid from the ears.
