The Respiratory System Essay

Answer 2: The respiratory system functions in the exchange of gases with the outside environment. Oxygen is inhaled through the nasal cavity or the mouth, and it travels to the alveoli in the lungs. There, the capillaries exchange the oxygen for carbon dioxide. The oxygenated blood flows back to the heart from the lungs. It enters the left side of the heart and is delivered to all the body tissues via the aorta. In the capillaries of the body tissues, oxygen is exchanged for carbon dioxide. This deoxygenated blood flows back to the right side of the heart and then to the lung. In the capillaries that run across the alveoli, carbon dioxide is exchanged for oxygen that has recently been inhaled. The carbon dioxide will then be exhaled through the mouth and nasal cavity.

The respiratory system is a complex organ structure of the human body anatomy, and the primary purpose of this system is to supply the blood with oxygen in order for the blood vessels to carry the precious gaseous element to all parts of the body to accomplish cell respiration. The respiratory system completes this important function of breathing throughout inspiration. In the breathing process inhaling oxygen is essential for cells to metabolize nutrients and carry out some other tasks, but it must occur simultaneously with exhaling when the carbon dioxide is excreted, this exchange of gases is the respiratory system's means of getting oxygen to the blood (McGowan, Jefferies & Turley, 2004).

Gas exchange occurs between the air and blood in the lungs. Since the oxygen saturation of air is higher in the lungs than in the blood, oxygen diffuses from air to blood. Carbon dioxide moves from the blood to the air within the lungs by diffusing down its concentration gradient. As a result of this exchange, the inspired air contains more oxygen and less carbon dioxide than the expired air. The lungs provide necessary oxygen to the body, in addition to removing carbon dioxide. More importantly, blood leaving the lungs has a higher oxygen and lower carbon dioxide concentration than the blood delivered to the lungs in the pulmonary arteries. This is because the lungs function to bring the blood into gaseous equilibrium in the air. Gas exchange between the air and blood occurs entirely by diffusion through the lung tissue

The blood that travels to the tissues and organs in the body have a high level of oxygen. Diffusion occurs between the capillaries and the body’s tissues and organs. Oxygen diffuses from the blood into the body’s cells and tissues, whereas carbon dioxide is diffused from the body’s tissues and organs into the blood where it then travels to the lungs. Here, it diffuses across the thin walls of the alveoli, where it is removed out of the body by exhalation.

This refers to the process of Oxygen and Carbon Dioxide moving between the lungs and blood. Diffusion occurs when molecules move from an area of high concentration to an area of low concentration. This occurs during gaseous exchange as the blood in the capillaries surrounding the alveoli has a lower oxygen concentration of Oxygen than the air in the alveoli which has just been inhaled. Both alveoli and capillaries have walls which are only one cell thick and allow gases to diffuse across them. The same happens with Carbon Dioxide. The blood in the surrounding capillaries has a higher concentration of CO2 than the inspired air due to it being a waste product of energy production. Therefore CO2 diffuses the other way, from the capillaries, into the alveoli where it can then be

Air is entered through the mouth and then travels down to the lungs. As gases move between the air within the alveoli and the bloodstream within the capillaries, they must cross a thin barrier of alveolar cells and one layer of capillary cells. As oxygen within the alveolar air is of higher concentration than the oxygen within the bloodstream, oxygen

In general, mammals have a closed circulatory system allowing them to ventilate easily. Air is inhaled by mammals through their mouths when their diaphragm contracts before travelling down the trachea. Air enters the lungs through the trachea, which splits into two bronchi and then smaller bronchioles. All of these tubes are held open by rings of cartilage. It is on the bronchioles where alveoli are. Alveoli are the gas exchange surface in mammals. Alveoli provide a moist gas exchange surface in which oxygen diffuses from the water into the alveoli. The oxygen diffuses from the alveoli to the blood capillaries surrounding them before the blood gets transported to the many cells needed because of respiration. The blood supply is extensive, which means that oxygen is carried away to the cells as soon as it has diffused into the blood.

Air is inhaled from the mouth and/or nose and goes through the trachea. The trachea is then split into the bronchial tubes. The bronchial tubes travel through the lungs and eventually split into tiny tubes called the bronchioles, at the end of a bronchiole, there is a sac called the alveoli. The alveoli is surrounded by blood vessels called the capillaries. The initially inhaled air passes through the alveoli walls and into the blood.

The Respiratory System: The respiratory system includes: the lungs, alveoli, nares, glottis, trachea, bronchi, larynx, the esophagus, and diaphragm. Oxygen is inhaled and carried throughout the body through all of these parts of the body and released using the same parts. The location of these parts are primarily between the throat and ribs with veins being used to carry oxygen throughout the body.

The diaphragm separates the chest and the abdomen as well as this it has a large role in breathing. The diaphragm moves down when we breathe in which expands the chest cavity making room for air to enter through the nasal cavity or mouth. When we breathe out the diaphragm moves upwards, forcing the chest cavity to reduce in size and pushing the gases in the lungs up and out of either the nose or mouth.

The way the Respiratory System works is complicated . It also is surprisingly fast in what it does. First the Diaphragm moves downwards which causes the lungs to expand creating a vacuum for air . Air enters the mouth or nose and goes through the Pharynx and into the Larynx to the vocal cords .The air then goes down the Trachea and into two Bronchi which feed into the lungs .Then air reaches tiny little itty bitty sacs called Alveoli .Which pass oxygen into the bloodstream.When the Diaphragm moves upwards air moves out the lungs up the Trachea through the Pharynx and out the mouth or

I am an oxygen molecule and will be going on a journey through the respiratory system. I begin my journey in the nose. In the nose I am being inhaled and prickled by tiny little hairs that filter me. I am also being moistened by mucus, green/yellow slimy mucus. Now I am sliding through the adams apple or voice box, into the trachea and the pharynx. Leading me into the bronchi tubes I am being seperated into the tree like branches called brochioles in the lungs. As the tubes get smaller and smaller I make my way down to the alveoli, which are smaller air sacs that fill with air when you breathe. In the alveoli there are tiny blood vessles called capillaries. The walls of the alveoli and capillaries are very thin. Finally by the alveoli

The bronchi and bronchiole tubes are loosely wrapped with muscle. During regular breathing, the muscles around these airways are relaxed (5). This allows air to flow freely through these passageways to the alveoli. However, during an asthma attack, air has trouble reaching the alveoli, which prevents the body from receiving oxygen. This is because the airways become smaller. Firstly, the muscles around the airways spasm and contract. This then causes inflammation of the bronchioles and bronchi themselves, which causes a mucus to be produced.

The main system effected by Emphysema is the respiratory system. Positioned in the left and right sides of the thorax is the lungs which are protected by a membrane which gives the lungs huge elasticity to grow when they gather with air. When looking at the lungs microscopically, the lobes of the lungs are compiled of hundred of little alveoli sacs where the exchanging of oxygen and carbon dioxide happen (Shah, 2010). These alveoli can be located at the closing of the bronchioles and are encompassed by vessels where blood travels. Bronchioles are two tubules that transport oxygen into the lungs and are lined with microscopic cilia hairs.

Your lungs are 2 wipe like organs in your mid-section. Your right lung has 3 segments, called flaps. Your left lung has 2 flaps. The left lung is littler in light of the fact that the heart takes up additional room on that side of the body. When you take in, air enters through your mouth or nose and goes into your lungs through the trachea (windpipe). The trachea partitions into tubes called bronchi (solitary, bronchus), which enter the lungs and gap into littler bronchi. These gaps to frame littler branches called bronchioles. Toward the end of the bronchioles are small air sacs known as alveoli. The alveoli retain oxygen from the breathed in air into your blood and expel carbon dioxide from the blood. This is removed from the body when
