Oxygen Diffusion

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

The complexity of the respiratory system and the physiology behind pulmonary respiration can be considered extraordinary high. Within the single system, individual organs, actions and co-ordinations are culminated to equate in the survival of humans. The respiratory system carries out many roles within the body; control of bodily pH, aid in speech production and olfaction, regulation of blood pressure and promotion of venous and lymphatic flow. Although these function are necessary to optimally function, the exchange of gases from the internal bodily environment to the external bodily environment is the most important function and role of the respiratory system (Martini, Ober, Nath 2011).

It is stratified in temperature, with warmer layers higher up and cooler layers farther down. This is in contrast to the troposphere near the Earth's surface, which is cooler higher up and warmer farther down. The border of the troposphere and stratosphere, the tropopause, is marked by where this inversion begins, which in terms of atmospheric thermodynamics is the equilibrium level. The stratosphere is situated between about 6 mi and 30 mi altitude above the surface at moderate latitudes, while at the poles it starts at about 5 mi altitude.

The air with then travel through the bronchi, which branches off into bronchioles. Each bronchiole has lots of very little air sacs called alveoli. Alveoli hold the gas and are the gas exchange site for exchange between the lungs and blood, and is what allows the oxygen to get into the blood, by being surrounded my lots of capillaries taking the oxygen away. This system is adaptation of the lungs. Additionally, there are is another adaptation of a humans gas exchange system, the first is ventilation or in short breathing.

The Respiratory System is designed to get oxygen into the body and carbon dioxide out. Once external respiration takes place exchanges of gases between outside air (atmosphere), to inside blood and cells takes place. Internal respiration continues from this exchanging of gases from blood and tissue fluids. Cellular respiration further continues the process and helps fuel the production of ATP which is the body’s essential energy source. (Johnson 2010 Chp.15)

The lungs are essential respiratory organs in humans which enable us to breathe. Our lungs are specialised structures that allow us to exchange gases. We require oxygen from the air to enter our blood, as all cells need it to function. We also need to get rid of carbon dioxide which is a product of many metabolic reactions within our cells. Our lungs allow this gas exchange so we can get rid of carbon dioxide and acquire oxygen. Each person has two lungs that are connected by our trachea (windpipe). The trachea separates into two bronchi, one of each leads to a lung. These bronchi then branch off into smaller bronchioles. The bronchioles are then connected to small air

Our bodies need oxygen to produce energy. To start, the body Max is in takes a deep breath. Oxygen comes into the body either through the nose or mouth. We’ll say it came in through the nose. In the nose, mucus moistens and cleans the air while cilia sweeps the mucus to your throat, where you swallow it. Then the air travels through the pharynx, trachea, and bronchi to reach the lungs. Here is where the gas exchange happens. Inside the lungs are these little sacs called alveoli. These alveoli are covered in capillaries. Here the bloodstream flows, and the blood picks up oxygen, and drops off CO2, which then is breathed out. Then the blood goes back to the heart, where it is then taken to Max.

Mammals use a ventilation system to carry out gas exchange. Diffusion of the respiratory gases occurs because the body needs to get rid of the carbon dioxide (a product of cell respiration) through exhalation and needs to absorb oxygen as oxygen is vital for cell respiration to make ATP. Oxygen in the air is ventilated into the body by inhalation (moving air from the atmosphere into the lungs) through either the mouth or he nasal cavity, after which it travels down the trachea (throat) towards the lungs. The first thing the air comes in contract with is the bronchi, which are The airways of the lungs, after a person takes in a breath of air, the air travels through the nose or mouth, down into the trachea, The trachea then divides two main

The Troposphere is the lowest layer from Earth of Earth’s atmosphere. In the troposphere is where all weather takes place. The second layer is the Stratosphere which has warmer layers than most of the atmosphere. The Mesosphere is the third layer of Earth’s atmosphere. In this layer temperature decreases with altitude. It also includes the coldest places on Earth. The next layer is the Ozone. In the Ozone layer gases and chemicals protect us from harmful Uv radiation from the sun. The last and final layer of the atmosphere is the Thermosphere. In the Thermosphere Uv radiation is captured by the sun and warms up this layer. This is the warmest layer of all of Earth’s atmosphere. Also in this layer radio waves are refracted due to the solar radiation interfering with

When we breathe; exhalation moves the diaphragm up into the chest cavity and reduces the amount of space in it. This forces the air, which is thick with carbon dioxide at that point, out of the lungs and trachea. It then exits the body through the nose or mouth. Usually, this requires no physical effort from the body and is something that is done naturally. Diffusion of oxygen into the blood takes place at the alveoli (air sacs).

Osmosis and diffusion are two important processes in the human body that help in the functioning of cells and homeostasis, or maintaining balance within the body. Osmosis is the movement of water from a higher concentration to a lower concentration, and its purpose is to maintain stability between a solvent (water) and a solute. Diffusion is the movement of solutes down their concentration gradient, toward a lesser concentration of solutes, in order to pass a membrane, such as the lipid bilayer of the plasma membrane (Tortora and Derrickson 2012). Diffusion requires no energy and is affected by many different aspects including heat, causing the reaction to occur at a more rapid rate, the size of the particle, and the amount of space in which the diffusion must cover (Tortora and Derrickson 2012). Osmosis is a form of diffusion that is more so for water, and both require no energy. The phospholipid bilayer of the cell membrane is a protective barrier against foreign materials that could harm the cell. The membrane is what is defined as selectively permeable (Tortora and Derrickson 2012) because it only allows certain materials get into it, while keeping others from moving out. The bilayer of the membrane has hydrophilic heads, which work well with water, and hydrophobic tails, which repel water. This difference in the head and tails is what causes only certain materials to be able to enter the membrane without help. Materials that can get in are small, gaseous, and

                   Have you ever had any trouble breathing in your life? No? Well consider yourself lucky. Breathing is an essential thing to life. You don’t breathe, you don’t live. That’s just the way it is. When you breathe in, the lungs take that oxygen and release the carbon dioxide as a waste product into the atmosphere. This is what keeps the body regulated and gets the metabolism going. The process of aspiration is an ongoing phenomenon. Everyone is constantly breathing in and out because our lungs can only take in so much oxygen. We constantly breathe more and more to live.

Normal respiration consists of inhalation and exhalation. Inhalation is taking in oxygen and delivering it to all cells in the body and exhalation is picking up carbon dioxide waster product of cells and taking it out. Air travel from the nose or mouth into the larynx into the trachea and ends up in the lungs where oxygen is dropped and carbon dioxide is picked up. Oxygen is really important for cell function and when oxygen is not delivered, cells begin to die. So when process of breathing does not work properly other methods of delivering oxygen are used such as tracheostomy.

The respiratory system is made up of the organs in the body which help you to breathe. Breathing is how our body takes in the oxygen required to break down food such as glucose into the energy necessary for the body’s processes by the process of respiration. The lungs are the main organs in the respiratory system. Red blood cells take oxygen from the lungs to the body cells which require it. They then pick up carbon dioxide, the waste product of respiration and carries it back to the lungs where it is removed from the body through exhalation. The other parts of the respiratory system are; the trachea, also known as the windpipe, which filters the air that we breathe in and branches out into the bronchi. The bronchi are the two tubes which carry air directly into the lungs and the diaphragm which contracts when inhaling to enlarge the space in the lungs

which is equal to ~200° F. This is the coldest layer in the atmosphere. The thermosphere is final thermally definitive layer of the atmosphere. In this layer, temperatures can reach up to up to 725° - 1, or 225° C. The thermosphere can be divided on the basis of chemistry. The lower thermosphere, the ionosphere extends from roughly 80 kilometers, or 50 miles, too somewhere around 300 to 600 kilometers out. After the ionosphere comes the exosphere. The exosphere is the second outer layer of the thermosphere. It lies beyond about 500-1,000 kilometers and is defined by an increasing hydrogen and helium level. This is because the oxygen and nitrogen that control the lower atmosphere have been broken into ions in the ionosphere. The layer that secedes from the exosphere is the homosphere. The homosphere is the portion of the lower atmosphere with almost no Ionization. Finally, the heterosphere, the area in which you get varying mixes of gas molecules and ions, is the last layer in the thermal structure of our atmosphere. It reaches heights between 80 and 10,000 kilometers. These layers show the thermal structure of our atmosphere.
