The oxygenated blood then makes its way to the pulmonary veins. These four veins, two from each lung, carry oxygen-rich blood to the left side of the heart, where it is pumped to all parts of the body. The carbon dioxide the blood left behind moves into the alveoli and gets expelled in our exhaled breath.
The diaphragm, a dome-shaped muscle at the bottom of the lungs, controls breathing and separates the chest cavity from the abdominal cavity. When air gets taken in, the diaphragm tightens and moves downward, making more space for the lungs to fill with air and expand, according to the National Heart, Lung and Blood Institute. During exhalation, the diaphragm expands and compresses the lungs, forcing air out.
Diseases and conditions of the respiratory system fall into two categories: Infections, such as influenza , bacterial pneumonia and enterovirus respiratory virus, and chronic diseases, such as asthma and chronic obstructive pulmonary disease COPD. Not much can be done for viral infections but to let them run their course, according to Dr.
Neal Chaisson, who practices pulmonary medicine at the Cleveland Clinic. For most healthy individuals, the most common respiratory ailment they may face is an infection, said Dr. A cough is the first symptom, possibly accompanied by a fever. Related: The gross science of a cough and a sneeze. 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.
Exercise can also induce asthma. For some people, asthma is a mild irritation, but for others it can be a life-threatening condition, according to the Mayo Clinic. Asthma cannot be cured, but its symptoms can be managed. Early identification and treatment can prevent long-term damage and stop asthma from getting worse over time. COPD is a chronic and progressive disease in which the air flow in and out of the lungs decreases, making it harder to breathe. COPD is a combination of chronic bronchitis inflammation of the bronchial tubes and emphysema damaged alveoli , according to the Mayo Clinic.
Smoking is the leading cause of COPD. Over time, the airways of people with COPD become inflamed and thicken, making it harder to get rid of waste carbon dioxide, according to the American Lung Association. As the disease progresses, patients experience a shortness of breath, and it can limit activity. COPD has no cure, but it can be treated. Lung cancer is often associated with smoking, but the disease can affect nonsmokers as well.
It is the second most common cancer for both men and women, outranked by prostate and breast cancers, respectively. The American Cancer Society ACS estimates that in , there will be about , new cases of lung cancer , in men and , in women and around , deaths from lung cancer 69, in men and 62, in women in the United States.
However, the number of lung cancer deaths has been on a downward slope in recent years due to advances in treatment and early detection. Most people diagnosed with lung cancer are older than 65, and the average age of people diagnosed with lung cancer is 70, according to ACS.

Imagine your on the labor and delivery floor of a hospital and you hear a loud and robust cry, signaling the birth of a new born baby. Have you ever wondered why? The respiratory system is a group of organs and structures that helps us breathe. It is made up of the lungs, airways, muscles, and linked blood vessels. The airways are the pipes that both carry oxygen-rich air to the lungs and carry carbon dioxide out of the lungs. These include the nose and linked air […].
The nose is superior to the mouth. The pharynx is posterior to the nasal and oral cavities. The larynx is inferior to the pharynx and connects the pharynx to the trachea. The […]. The respiratory system consists of organs that oversee inhaling of oxygen, exchanging gases, and exhaling of carbon dioxide.

Home Page lung diseases Essay example. Open Document. Around 10, litres of air move in and out of your lungs every day. Every breath you take contains foreign bodies and germs, not just the oxygen in it so the lung has a physical and chemical defence system that is used to stop unwanted substances from getting into the body. Two thin layers of tissue called the pleura cover each lung.
They allow the lungs to contract and relax by sliding over one another when you breathe. Each lung weighs around 1lb but the left lung is a little smaller than the right as the right has more space and does not have to share its space with the heart, unlike the left lung which does. Every part of your body needs oxygen from the air to survive. It is carried around the body by red blood cells in the bloodstream. Oxygen cannot get into the blood directly, through the skin, a complicated system is present in the lungs to absorb it from the air and transfer it into the bloodstream.
So, if the lungs systems are not functioning correctly it can cause many health problems and complications. I will be talking about the different types of lung diseases, their symptoms, the course of infection and the transmission of the lung diseases. There are a lot of things that can cause harm to your lungs and give you lung diseases later on. One of these risk factors is smoking. Smoking is very hazardous to your health and has been linked to many diseases such as lung disease, cancer, heart and circulation diseases and osteoporosis to name but a few.
Smoking can damage the tiny air sacs alveoli and airways in your lungs. The damage induced by smoking to your blood vessels will see your heart rate and blood pressure increase which puts you at risk of heart disease and or a stroke. It affects your reproductive system and sex organs but is more greatly recognised as the biggest cause of chronic obstructive pulmonary disease COPD.
COPD is a disease caused by obstruction to airflow that interferes with normal breathing. Bronchitis means 'inflammation of the bronchi'. These are the tubes or airways which carry oxygen from the air through the lungs. This inflammation increases mucus production in the airways, producing phlegm which makes you cough.
Emphysema is where the alveoli air sacs in the lungs lose their elasticity. This reduces the support of the airways, causing them to narrow. It also means the lungs are not as good at getting oxygen into the body, so you may have to breathe harder. This can result in shortness of breath. It does not include other obstructive diseases such as asthma. It causes damage to the airways and lungs which leads to the development of this long-term condition. Smoking can also make symptoms worse for people with asthma and other lung conditions too.
Stopping smoking is essential to prevent the development of COPD or slow down its progression. If you have a lung condition such as COPD, you are more likely to feel increasingly breathless if you smoke, or are exposed to second-hand smoke. COPD leads to damaged airways in the lungs, causing them to become narrower and making it harder for air to get in and out of the lungs.
It involves the complex mechanisms on Depression and Anxiety in help supply human organism with a constant stream of oxygen to stay alive and remove and depression are prevalent in patients with moderate-to-severe chronic obstructive respiratory processes to maintain human known to how to write xml file in net patient-centered outcomes and quality of life.
