In the right lung, there are three lobes, the superior, middle, and inferior. It is divided into three lobes by two interlobular fissures, transverse fissure and oblique fissure (Taylor, n.d.). The superior and middle lobe are separated by a transverse fissure and the middle and inferior lobe are separated by an oblique fissure (“Structure of the Lungs”, n.d.). The left lung and right lung are not the same though. As you see, the right lung has only three lobes, as the left lung has two. They are different in size as the left lung is smaller than the right. The reasoning for this is because your hearts sets in between the lungs so the heart uses some of the space that your left lung is (Taylor, n.d.). The function of the lungs is pulmonary ventilation, or breathing. Air is inhaled through your nostrils which pass through your trachea and enters the bronchi. Bronchi are two tubes that carry air to the lungs. Bronchioles are smaller branches of bronchi that split off (“Structure of the Lungs”, n.d.). Bronchioles divide into even smaller structures to form respiratory bronchioles which lead to the alveolar ducts. Then there are air sacs called alveoli. They are the basic functional units of lungs and have simple squamous epithelial cells. Alveoli cover about 60-70m. Oxygen is exchanged for carbon dioxide from the bloodstream by microscopic structures of the lungs called alveoli. Pleura protects the lungs with a…
Physiology of the lungs: The lungs working properly will result in the successful exchange of gases. During inhalation the diaphragm contracts, which draws air into the lungs. All the muscle groups act together expanding the lungs. The trachea pulls air into the lungs via the bronchi. The bronchioles then are a functional branch of the bronchi. The tiny pockets of alveoli store air briefly in order for oxygen to be absorbed in the bloodstream. Through the alveoli the gas exchange into the lungs occurs.…
• Describe an overview of the key anatomical parts of the respiratory system and how it works.…
The function of the respiratory system is to remove carbon dioxide and water from the body, also to maintain an oxygen to supply to each of the cells. In the respiratory system there is internal and external respiration. The internal respiration is carried out in the body cells whereas external respiration consists of blood transport, breathing and gaseous exchange. The respiratory system contains alveoli which allow the diffusion of oxygen into the blood stream and carbon dioxide out of the blood stream. This process allows the respiratory and cardiovascular system to work together to transfer the nutrients. Internal respiration is also known as cell respiration where the cells are provided with energy in order to perform…
The organs of the respiratory system ensure that oxygen enters the body and carbon dioxide leaves the body. Ventilation is another term for breathing that includes both…
The respiratory system takes away the oxygen needed for the body from the outside of the body and brings it into the lungs where it is pushed around the lungs into the blood stream. The circulatory system brings and carries the…
Your respiratory system is made up of the organs in your body that help you to breathe. The goal of breathing is to deliver oxygen to the body and to take away carbon dioxide.…
A lung is associated with respiratory system, the function of the lungs is to let out carbon dioxide and bring in oxygen.…
The main function of the respiratory system is to inhale oxygen and exhale the waste product carbon dioxide. Oxygen is breathed through the mouth and nostrils into the lungs. The gas then diffuses through the alveolar walls and into red blood cells (erythrocytes). Carbon dioxide carried back within red blood cells diffuses back through the alveolar walls and is exhaled out through the mouth.…
The respiratory system is responsible for the exchange and intake of oxygen and carbon dioxide.…
2.) Ventilation is the movement of air into and out of the lungs. This is important for the process…
The ribs, rib muscles and diaphragm all play a part in allowing air into and out of the lungs, (oxygen going into the body and carbon dioxide leaving the body). This is known as ventilation. When we breathe in we inhale and when we breathe out we exhale.…
3. In a person’s body that exercises, the lungs are important in sending more oxygen to the person’s cells, because the body consumes all available resources. The person’s body takes in oxygen quicker as they exercise, resulting in the person breathing harder/faster to keep up with the rate consumption.…
The expandation of your lungs causes the air to be breathed in through your nose or mouth. The air goes down your windpipe and into lungs. Through your bronchial tubes it helps the air to reach and enter the alveoli or air sacs.…
The lungs form is pretty much a sac that is like a balloon. It is flexible in order to inflate and deflate. The lung being like a balloon and flexible allows it to be able to inflate when inhaling air then deflate when exhaling air.…
