Respiration, types of respiration and anatomy of Human respiratory system

Jan 15, The lungs are organs of the respiratory system that allow us to take in and expel air. In the breathing process, the lungs take in oxygen from the air through inhalation. Carbon dioxide produced by cellular respiration is in turn released through exhalation. External respiration occurs in the lungs where oxygen diffuses into the blood and carbon dioxide diffuses into the alveolar air. Internal respiration occurs in the metabolizing tissues, where oxygen diffuses out of the blood and carbon dioxide diffuses out of the cells. Similarly, what respiratory disorder was your patient suffering from? The term lung disease refers to many disorders affecting the lungs, such as .

Respiration is the process in which organisms exchange gases between their body cells and the environment. From prokaryotic bacteria and archaeans to eukaryotic protistsfungiplantsand animalsall living organisms undergo respiration. Respiration may refer to any of the three elements of the process. Firstrespiration may refer to external respiration or the process of breathing inhalation and exhalationalso called ventilation. Secondlyrespiration may refer to internal respiration, which is the diffusion of gases between body fluids blood and interstitial fluid and tissues.

Finallyrespiration may refer to the metabolic processes of converting the energy stored in biological molecules to usable energy in the form of ATP. This process may ocurs the consumption of oxygen and production of carbon dioxide, as seen in aerobic cellular respirationor may not involve the consumption of oxygen, as in the case of anaerobic respiration. One method for obtaining oxygen from the environment is through external respiration or breathing.

In animal organisms, the process of external respiration is performed in a number of different ways. Animals that lack specialized organs for respiration rely on diffusion across external tissue surfaces to obtain oxygen.

Others either have organs specialized for gas exchange or have a complete respiratory system. In organisms such as nematodes roundwormsgases wyat nutrients are exchanged with the external environment by diffusion across the ij of the animals body. Insects and spiders have respiratory organs called tracheae, while fish have gills as sites for gas exchange.

Humans and other mammals have a respiratory system with specialized respiratory organs lungs and tissues. In the human body, oxygen is taken into the lungs by inhalation and carbon dioxide ln expelled from the lungs by exhalation.

External respiration in mammals encompasses how much is it to build a house in canada mechanical processes related to breathing. This includes contraction and relaxation of the diaphragm and accessory musclesas well as breathing rate. External respiratory processes explain how oxygen is obtained, but how to get general contractor license in nj does lujgs get to body cells?

Internal respiration involves the transportation of gases between the blood and body tissues. Oxygen dhat the lungs diffuses across the thin epithelium of rspiration alveoli air sacs into surrounding capillaries containing oxygen depleted blood. At the same time, carbon dioxide diffuses in the opposite direction from the blood to lung what does a taskbar look like and is expelled. Oxygen rich blood is reepiration by the circulatory system from lung capillaries to body cells and tissues.

While oxygen is being dropped off at cells, waht dioxide is being picked up and transported from tissue cells to the lungs.

The oxygen obtained from internal respiration is jn by cells in cellular respiration. In order to access the energy stored in the foods we eat, biological molecules composing foods carbohydratesproteinsetc, must be broken down into forms that the body can utilize. This is accomplished through the digestive process where food is broken down and nutrients are absorbed into the blood. As blood is reapiration throughout the body, nutrients are transported to body cells.

In cellular respiration, glucose obtained from digestion is split into its constituent parts for the production of energy. Through a series of steps, glucose and oxygen are converted to carbon dioxide CO 2water H 2 Oand the high energy molecule adenosine triphosphate ATP. Carbon dioxide and water formed in the process diffuse into the respirationn fluid surrounding cells.

From there, CO 2 diffuses into blood plasma and red blood cells. ATP generated in the process provides the energy needed to perform normal cellular functions, such as macromolecule synthesis, muscle contraction, cilia and flagella movement, and cell division. Aerobic cellular respiration consists of whwt stages: glycolysiscitric acid cycle Krebs Cycleand electron transport with oxidative phosphorylation.

In total, 38 ATP molecules are produced by prokaryotes in the oxidation of a single glucose molecule. Aerobic respiration only occurs in the presence of oxygen. When oxygen supply is low, only a small amount of ATP can be generated in the cell cytoplasm by glycolysis. Although pyruvate can not enter the Krebs cycle or electron transport chain without oxygen, it can still be used to generate additional ATP by fermentation.

Fermentation is another type of cellular respiration, a chemical process for the breakdown of carbohydrates into smaller compounds for the production of ATP. In comparison to aerobic respiration, only a small amount of ATP is produced in fermentation.

This is because glucose is only partially broken down. Some organisms are facultative anaerobes and can utilize both fermentation when oxygen is low or not available and aerobic respiration when oxygen is available.

Two common types of fermentation are kungs acid fermentation and alcoholic ethanol fermentation. Glycolysis is the lunsg stage in each process. Lactic Acid Fermentation. Lactic acid fermentation is commonly performed by muscle cells when oxygen levels become depleted. Lactate is converted to lactic acid which can accumulate resoiration high levels in muscle cells during exercise. Lactic acid increases muscle acidity respiratiln causes a burning sensation that occurs during extreme exertion. Once normal oxygen levels are restored, pyruvate can enter aerobic respiration and much more energy can be generated to aid in recovery.

Increased blood flow helps to deliver oxygen to and remove lactic acid from muscle what type of respiration occurs in the lungs. Alcoholic Fermentation. In alcoholic fermentation, pyruvate is converted to ethanol and CO 2. Alcoholic fermentation is performed by plantsyeast, and some species of bacteria.

This process is used in the production of alcoholic drinks, fuel, and baked goods. How do extremophiles like some bacteria what is the best faction in lego universe archaeans survive in environments without oxygen? The answer is by anaerobic respiration. This type of respiration occurs without oxygen and involves the consumption of another molecule nitrate, luungs, iron, carbon dioxide, etc.

Unlike in fermentation, anaerobic lnugs involves the formation of an electrochemical gradient by an electron transport system that results in the production of a number of ATP molecules. Unlike in aerobic respiration, the final electron recipient is a molecule respiraiton than oxygen. Many anaerobic organisms are obligate anaerobes; they don't perform oxidative phosphorylation and die in the presence of oxygen.

Others lujgs facultative anaerobes and can also perform aerobic ooccurs when oxygen is available. Share Flipboard Email. Regina Bailey. Biology Expert.

Anatomy of Human respiratory system

Aug 20, An Introduction to Types of Respiration Types of Respiration: External and Internal. When inhaling, the diaphragm contracts and the lungs expand, pushing the Cellular Respiration. The three processes of ATP production or celluar respiration include . High partial pressure = more gas in solution. External (pulmonary) respiration. This type of respiration occurs in the lungs. Air in the alveoli (high PO2, low PCO2). Blood in pulmonary capillaries (low PO2, high PCO2) Oxygen diffuses into capillaries and CO2 diffuses out of capillaries to be exhaled. Mar 07, Types of respiration. There are two types of respiration depending upon availability of oxygen. 1. Aerobic respiration: It occur in the presence of Oxygen. The food is oxidized in the presence of oxygen in cellular level liberating CO2 and water along with energy in the form of ATP.

Complement fixation test: principle, procedure, result interpretation, applications and limitations. Respiration, types of respiration and anatomy of Human respiratory system Respiration Respiration is defined as the biochemical process by which the digested foods are oxidized liberating the energy.

In the process, oxygen is utilized and carbon-dioxide is released. Overall respiration process involves three process. External respiration: it is a simple process of exchange of gases O2 and CO2 between the respiratory surface and the environment.

Transport of gases between the respiratory surface and the body tissue. Internal or cellular respiration : cellular respiration occur in mitrochondria of every cell, where digested food is oxidized releasing energy in the storable form ie.

Types of respiration There are two types of respiration depending upon availability of oxygen 1. Aerobic respiration: It occur in the presence of Oxygen.

The food is oxidized in the presence of oxygen in cellular level liberating CO2 and water along with energy in the form of ATP. Complete oxidation of 1 molecule of glucose liberate 38 molecule of ATP during glycolysis. Anaerobic respiration: In the absence of oxygen, food is oxidized anaerobically without utilizing o2. Anaerobic respiration is also known as fermentation as organic compounds are also produced as byproducts.

One glucose molecule on anaerobic oxidation releases 2 ATP molecule only. Anaerobic respiration occur in deep seated tissue, in germinating seeds, parasites and bacteria. Anatomy of Human respiratory system The organs of the respiratory system are: nose external nares and nasal chamber Internal nares and pharynx larynx trachea two bronchi one bronchus to each lung bronchioles and smaller air passages two lungs and their coverings, the pleura muscles of breathing the intercostal muscles and the diaphragm.

Nose external nare and nasal chamber Structurally the nose can be divided into the external portion which is in fact termed as the nose and the internal portions being the nasal cavities.

The nose is the only visible part of the respiratory system, protruding from the face, and lying in between the forehead and the upper lip.

Opening is known as nostril. The two nostrils are separated by nasal septum. The two nostril openings leading to two nasal chambers or cavities. The nasal cavity is the main route of air entry, and consists of a large irregular cavity divided into two equal passages by a septum. The posterior bony part of the septum is formed by the perpendicular plate of the ethmoid bone and the vomer.

Anteriorly, it consists of hyaline cartilage. The nasal cavity is lined with very vascular ciliated columnar epithelium which contains mucus-secreting goblet cells. The functions of nasal passage are:. Next Complement fixation test: principle, procedure, result interpretation, applications and limitations.
