Respiratory System The respiratory system consists of a series of tubes that air passes on its journey from the nostrils. The nostrils open into the nasal cavities, which are lined with moist eiliateol epithelium. Whether one breathes through the nose or the mouth, a breath of air enters the body and flows through the nasal cavity to the pharynx (throat). The back of the nasal cavities is continuous with the throat region, or pharying. Air flows through the larynx (voice box) and into the trachea, which divides into two bronchi, one going to each lung. The trachea and bronchi are supported by C-shaped rings of cartilage that prevent the tubes from collapsing as air is drawn into the body. The bronchi divide into thousands of bronchioles. The smallest bronchioles end in clusters of microscopic air sacs or alveoli. From them, oxygen diffuses into the blood of the multitude of capillaries enveloping each air sac. At the same time, carbon dioxide diffuses from the capillaries into the air sacs and is exhaled through the respiratory tubes. Both the trachea and bronchi are l...
When you breathe in, air containing carbon dioxide (CO2) and oxygen (O2) it moves down your trachea; a tunnel containing cartilage and smooth tissue. Air then travels through two hollow tubes called bronchi; narrow branches lined with smooth muscle, mucosal and ringed cartilage to support the structure. The bronchi divide out into smaller tunnels called bronchioles; are small branches 0.5-1mm, lined with muscular walls to help dilate and constrict the airway. At the end of the bronchioles are little air sacs called alveoli; which assist in gas exchange of O2 and CO2. (Eldridge, 2016) Towards the end of alveoli are small blood vessel capillaries. O2 is moved through the blood stream through theses small blood vessels (capillaries) at the end of the alveoli and the CO2 is then exhaled. (RolandMedically,
The circulatory system and respiratory system share a highly important relationship that is crucial to maintaining the life of an organism. In order for bodily processes to be performed, energy to be created, and homeostasis to be maintained, the exchange of oxygen from the external environment to the intracellular environment is performed by the relationship of these two systems. Starting at the heart, deoxygenated/carbon-dioxide (CO2)-rich blood is moved in through the superior and inferior vena cava into the right atrium, then into the right ventricle when the heart is relaxed. As the heart contracts, the deoxygenated blood is pumped through the pulmonary arteries to capillaries in the lungs. As the organism breathes and intakes oxygenated air, oxygen is exchanged with CO2 in the blood at the capillaries. As the organism breathes out, it expels the CO2 into the external environment. For the blood in the capillaries, it is then moved into pulmonary veins and make
In the lungs gas exchange occurs to re-oxidize the blood. Air travels through the respiratory tract to reach the lungs and back up to be exhaled into the environment. At the termination point of the respiratory tract lays the alveoli. The alveoli have a sac-like structure. In biological systems, the structure and functions of components are related. The alveoli have a structure specialized for efficient gaseous exchange. In the structure of the alveoli (alveolus), it looks as if it has the form of a hollow cavity that is paired with elastic fibers...
The Respiratory System is a process by which we take in oxygen and give off of carbon dioxide. It encompasses the breathing of a human being which is in one form of respiration, called external respiration. We have to perform this function in order to maintain life. Nonetheless, there are several complications associated with the Respiratory system; commonly bronchitis and Asthma.
The Circulatory System is a transportation and cooling system for the body. The Red Blood Cells act like billions of little mail men carrying all kinds of things that are needed by the cells, also RBC's carry oxygen and nutrients to the cells. All cells in the body require oxygen to remain alive. Also there is another kind of cells called white blood cells moving in the system. Why blood cells protect from bacteria and other things that are harmful. The Circulatory system contains vein arteries, veins are used to carry blood to the heart and arteries to carry the blood away. The blood inside veins is where most of the oxygen and nutrients are and is called deoxygenated and the color of the blood is dark red. However, blood in the arteries are also full of oxygen but is a bright red. The main components of the circulatory system are the heart, blood, and blood vessels.
The Respiratory system consists of the Nose, Lungs, trachea, larynx, pharynx, bronchi and bronchioles mainly. And are divided into an upper and Lower Tract.
The lungs are a vital part of the respiratory system, a group of organs and tissues that work together to help humans breathe. The system’s main job is to move fresh air into the body while removing waste gases. Lungs are important because every cell in the body needs oxygen to live. The air we breathe contains oxygen and other gases. Once in the lungs, oxygen is moved into the bloodstream and carried throughout the human body. The bloodstream then carries the waste gas back to the lungs where it is removed from the blood stream and then exhaled. The lungs and respiratory system automatically perform this vital process, called gas exchange (American Lung Association). Lungs contain millions of air sacs called alveoli. With each breath,
The Respiratory System 1. Define respiration. Respiration is the process of converting glucose to energy, which goes to every cell in the body. 2. Describe the organs of external respiration.
To introduce the respiratory system, use the SOS strategy found in the DE Techbook teacher section Silence is Golden. Show the video segment Cow’s Lungs in Explore More Resources with no audio and ask the students to describe what is happening and why. As they discuss aloud what they are seeing, educators will get an idea of what they understand, need to still master and want to know more about. Ask the students to record their observations in their notebooks. Then to finish up, have them explain to a partner what the video has demonstrated. As the students observe the cow’s lungs experiment, they will be isolating a single system and constructing a simplified model of it; imagining an artificial boundary between the respiratory system and
Healthy lung tissue is predominately soft, elastic connective tissue, designed to slide easily over the thorax with each breath. The lungs are covered with visceral pleura which glide fluidly over the parietal pleura of the thoracic cavity thanks to the serous secretion of pleural fluid (Marieb, 2006, p. 430). During inhalation, the lungs expand with air, similar to filling a balloon. The pliable latex of the balloon allows it to expand, just as the pliability of lungs and their components allows for expansion. During exhalation, the volume of air decrease causing a deflation, similar to letting air out of the balloon. However, unlike a balloon, the paired lungs are not filled with empty spaces; the bronchi enter the lungs and subdivide progressively smaller into bronchioles, a network of conducting passageways leading to the alveoli (Marieb, 2006, p. 433). Alveoli are small air sacs in the respiratory zone. The respiratory zone also consists of bronchioles and alveolar ducts, and is responsible for the exchange of oxygen and carbon dioxide (Marieb, 2006, p. 433).
Respiratory System Have you ever felt like you were out of breath. This all falls under the respiratory system. The respiratory system is divided into two different portions. The first portion is made up of the upper airway and the second portion is the lower airway. Muscles, respiratory distress, failure, hypoxic drive, etc.
The larynx prevents food and liquids from traveling down the air path ways which could result in choking. From the larynx, Bronchi trachea splits into two bronchi each leading to a lung, each lung is divided into lobes. The right lung has three lobes and the left has two lobes. The right lung is slightly larger than the left lung. The two lungs are mainly made of up connective tissue, which gives them their soft and spongy texture. The bronchi branch are smaller and are called bronchioles which are divided many more times in the lungs. The lungs is made up of connective tissue, blood, lymphatic tissue, air pathways and alveoli are at the end of the branches inside of the lungs. The alveoli sends oxygen and removes carbon dioxide. This is a basic view of how the respiratory system functions and if the respiratory system doesn’t do its job then this could lead to infectious diseases of the respiratory
Our respiratory system is made up of organs in our body then that helps you to breath. The Goal of breathing to take oxygen to the body. The air we breath splits in two’s the air and the body keeps the oxygen and gets rid of the carbon dioxide. the air goes into the lungs threw the noes then pass trachea
blood to the lungs, and the left side of the heart has to work harder
The trachea filters the air we breathe. At the end of the Trachea it splits into two which is called Bronchus. Bronchus are two air tubes that branch off to the Trachea and carry air directly into the lungs. The lungs are the main organ in the respiratory system. In the lungs, oxygen is taken into the body and carbon dioxide is breathed out. The red blood cells collect oxygen from the lungs and deliver it to other cells in our body and they also pick up the waste from the other cells (Carbon Dioxide) and bring it back to the lungs to get exhaled. The diaphragm is not part of where the air travels, but it is used to air in and out of the lungs. The diaphragm is a muscle that moves, causing a change in air pressure. When you breathe out, the diaphragm moves upward, which decreases the volume of the lungs, causing high pressure. When you breathe in, the diaphragm moves downwards in it can increase the volume of the lungs which causes negating pressure. These organs are equally useful as they all play a role to keep your respiratory system working. You need to
