nose helps to inhale air which is carried through the windpipe to the lungs then it purifies the air
NOSE: nose is a very important part of a respiratory system nose help us to English Healthcare it has years also in nose present in our nose which help us to stop the dust particles in years and all need oxygen got into our body that they are very helpful for us nose in the air which gone into the windpipe
WINDPIPE: windpipe when the nose get the year when the year according to the windpipe windpipe help us to reach out to air into the lungs it has also many parts for twin babies the main part that from it's a tube with helper 2 ke give the air for lungs
LUNG: Lungs Arthur last part fit aur oxygen School It's a last part of a respiratory system first person to the nose and 1 windpipe and then the lungs its main parts
BRONCHUS: branches of the part in the lungs where the oxygen is come from the branches oxygen is go to the lungs each bronchus is known as branchi
1. frogs when they are in water they breathe with their skin and when they are on land they breathe with lungs.
Adam's apple: In human males, the larynx grows larger during puberty and can be seen as a protruding part of the throat. This protrusion is known as the Adam's apple. ...
Secondary sexual characters are those features that help in distinguishing the male and the female body from each other.
Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. This results in a net gain of two ATP molecules. Life first evolved in the absence of oxygen, and glycolysis does not require oxygen.
Glycolysis takes place in the cytoplasm.

Pathway of air: nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles > alveoli (site of gas exchange)

respiratory system means the organs by which we respire
1.Frogs, like salamanders, newts and toads, are amphibians. Most amphibians begin their life cycles as water-dwelling animals, complete with gills for breathing underwater. As they grow to adulthood, amphibians normally become land-dwelling creatures, lose their gills and develop lungs for breathing. Frogs have lungs like we do and if their lungs fill with water, they can drown just like us. Frogs can also breathe through their skin. ... They use their skin to absorb oxygen when underwater, but if there is not enough oxygen in the water, they will drown.
2. During anaerobic respiration in plants (like yeast), ethanol, carbon dioxide and energy are the final products.(a)There is a build-up of lactic acid in the muscles during vigorous exercise. The lactic acid needs to be oxidised to carbon dioxide and water later.(b)The resultant products of anaerobic respiration if occurs in plants especially like yeasts are along with little amount of energy ethanol and carbon dioxide are released. So the yeast cells are widely used for fermentation process.
Some animal do have a sharp mind, and are able to think to few extent and they also have feelings of love and emotions. But it doesn't mean that they are always able to think to right direction. The reason is because no other animal, except humans are to develop brain's capacity continuously.Red blood cells collect the oxygen from the lungs and carry it to the parts of the body where it is needed, according to the American Lung Association. During the process, the red blood cells collect the carbon dioxide and transport it back to the lungs, where it leaves the body when we exhale.
Parts of the respiratory system
As we breathe, oxygen enters the nose or mouth and passes the sinuses, which are hollow spaces in the skull. Sinuses help regulate the temperature and humidity of the air we breathe.
The trachea, also called the windpipe, filters the air that is inhaled, according to the American Lung Association. It branches into the bronchi, which are two tubes that carry air into each lung. (Each one is called a bronchus.) The bronchial tubes are lined with tiny hairs called cilia. Cilia move back and forth, carrying mucus up and out. Mucus, a sticky fluid, collects dust, germs and other matter that has invaded the lungs. We expel mucus when we sneeze, cough, spit or swallow.
The bronchial tubes lead to the lobes of the lungs. The right lung has three lobes; the left lung has two, according to the American Lung Association. The left lung is smaller to allow room for the heart, according to York University. Lobes are filled with small, spongy sacs called alveoli, and this is where the exchange of oxygen and carbon dioxide occurs.
The alveolar walls are extremely thin (about 0.2 micrometers). These walls are composed of a single layer of tissues called epithelial cells and tiny blood vessels called pulmonary capillaries.
Blood passes through the capillaries. The pulmonary artery carries blood containing carbon dioxide to the air sacs, where the gas moves from the blood to the air. Oxygenated blood goes to the heart through the pulmonary vein, and the heart pumps it throughout the body.
The diaphragm, a dome-shaped muscle at the bottom of the lungs, controls breathing and separates the chest cavity from the abdominal cavity, the American Lung Association noted. When a breath it taken, it flattens out and pulls forward, making more space for the lungs. During exhalation, the diaphragm expands and forces air out.
Diseases of the respiratory system
Diseases and conditions of the respiratory system fall into two categories: viruses, such as influenza, bacterial pneumonia, enterovirus respiratory virus; and chronic diseases, such as asthma and chronic obstructive pulmonary disease (COPD). According to Dr. Neal Chaisson, who practices pulmonary medicine at the Cleveland Clinic, there is not much that can be done for viral infections but to let them run their course. "Antibiotics are not effective in treating viruses and the best thing to do is just rest," he said.
COPD is the intersection of three related conditions — chronic bronchitis, chronic asthma and emphysema, Chaisson told Live Science. It is a progressive disease that makes it increasingly difficult for sufferers to breath.
Asthma is a chronic inflammation of the lung airways that causes coughing, wheezing, chest tightness or shortness of breath, according to Tonya Winders, president of the Allergy & Asthma Network. These signs and symptoms may be worse when a person is exposed to their triggers, which can include air pollution, tobacco smoke, factory fumes, cleaning solvents, infections, pollens, foods, cold air, exercise, chemicals and medications.
Lung cancer is often associated with smoking, but the disease can affect non-smokers as well. Every year, about 16,000 to 24,000 Americans die of lung cancer, even though they have never smoked. In 2018, the American Cancer Society estimates there will be about 234,030 new cases of lung cancer (121,680 in men and 112,350 in women) and around 154,050 deaths from lung cancer (83,550 in men and 70,500 in women).
