Answer:
Respiratory System
Your respiratory system is the network of organs and tissues that help you breathe. This system helps your body absorb oxygen from the air so your organs can work. It also cleans waste gases, such as carbon dioxide, from your blood. Common problems include allergies, diseases or infections.
What is the respiratory system?
The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.

FUNCTION
What does the respiratory system do?
The respiratory system has many functions. Besides helping you inhale (breathe in) and exhale (breathe out), it:
Allows you to talk and to smell.
Warms air to match your body temperature and moisturizes it to the humidity level your body needs.
Delivers oxygen to the cells in your body.
Removes waste gases, including carbon dioxide, from the body when you exhale.
Protects your airways from harmful substances and irritants.
ANATOMY
What are the parts of the respiratory system?
The respiratory system has many different parts that work together to help you breathe. Each group of parts has many separate components.
Your airways deliver air to your lungs. Your airways are a complicated system that includes your:
Mouth and nose: Openings that pull air from outside your body into your respiratory system.
Sinuses: Hollow areas between the bones in your head that help regulate the temperature and humidity of the air you inhale.
Pharynx (throat): Tube that delivers air from your mouth and nose to the trachea (windpipe).
Trachea: Passage connecting your throat and lungs.
Bronchial tubes: Tubes at the bottom of your windpipe that connect into each lung.
Lungs: Two organs that remove oxygen from the air and pass it into your blood.
From your lungs, your bloodstream delivers oxygen to all your organs and other tissues.
Muscles and bones help move the air you inhale into and out of your lungs. Some of the bones and muscles in the respiratory system include your:
Diaphragm: Muscle that helps your lungs pull in air and push it out.
Ribs: Bones that surround and protect your lungs and heart.
When you breathe out, your blood carries carbon dioxide and other waste out of the body. Other components that work with the lungs and blood vessels include:
Alveoli: Tiny air sacs in the lungs where the exchange of oxygen and carbon dioxide takes place.
Bronchioles: Small branches of the bronchial tubes that lead to the alveoli.
Capillaries: Blood vessels in the alveoli walls that move oxygen and carbon dioxide.
Lung lobes: Sections of the lungs — three lobes in the right lung and two in the left lung.
Pleura: Thin sacs that surround each lung lobe and separate your lungs from the chest wall.
Some of the other components of your respiratory system include:
Cilia: Tiny hairs that move in a wave-like motion to filter dust and other irritants out of your airways.
Epiglottis: Tissue flap at the entrance to the trachea that closes when you swallow to keep food and liquids out of your airway.
Larynx (voice box): Hollow organ that allows you to talk and make sounds when air moves in and out.
CONDITIONS AND DISORDERS
What conditions affect the respiratory system?
Many conditions can affect the organs and tissues that make up the respiratory system. Some develop due to irritants you breathe in from the air, including viruses or bacteria that cause infection. Others occur as a result of disease or getting older.
Conditions that can cause inflammation (swelling, irritation and pain) or otherwise affect the respiratory system include:
Allergies: Inhaling proteins, such as dust, mold, and pollen, can cause respiratory allergies in some people. These proteins can cause inflammation in your airways.
Asthma: A chronic (long-term) disorder, asthma causes inflammation in the airways that can make breathing difficult.
Infection: Infections can lead to pneumonia (inflammation of the lungs) or bronchitis (inflammation of the bronchial tubes). Common respiratory infections include the flu (influenza) or a cold.
Disease: Respiratory disorders include lung cancer and chronic obstructive pulmonary disease (COPD). These illnesses can harm the respiratory system’s ability to deliver oxygen throughout the body and filter out waste gases.
Aging: Lung capacity decreases as you get older.
Damage: Damage to the respiratory system can cause breathing problems.
The characteristics of the respiratory system restrict where an organism is able to live, due to the availability and diversification of oxygen sources, not all living beings can obtain an oxygenation rate
What are the main factors that influence the solubility of oxygen?
There are, however, two factors that change its solubility:
- pressure
- and temperature.
The influence of pressure on a liquid can be stated by Henry's Law: "At constant temperature, the solubility of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid."
With this information, we can conclude that the characteristics of the respiratory system restrict where an organism is able to live, due to the availability and diversification of oxygen sources, not all living beings can obtain an oxygenation rate
