Respiratory Body System

Your respiratory system is made up of the organs in your body that help you to breathe. Respiration = Breathing

The respiratory system (or ventilatory system) is a biological systems consisting of specific organs and structures used for the process of respiration in an organism. The respiratory system is involved in the intake and exchange of oxygen and carbon dioxide between an organism and the environment.

Why do I sneeze?

Sneezing is like a cough in the upper breathing passages. It is the body's way of removing an irritant from the sensitive mucous membranes of the nose. Here are some things that can irritate the mucous membranes. Dust, pollen, pepper or even a cold blast of air are just some examples that may cause you to sneeze.

Why do I yawn?

When you are sleepy or drowsy the lungs do not take enough oxygen senses this shortage of oxygen and sends a message that causes you to take a deep long breath---a YAWN.from the air. This causes a shortage of oxygen in our bodies.

Why do I hiccup?

Hiccups are the sudden movements of the diaphragm. You have no control over hiccups. Here are some causes of hiccups. The diaphragm may get irritated, you may have eaten to fast, or maybe some substance in the blood could even have brought on the hiccups.

  • Ventilation

In respiratory physiology, ventilation (or ventilation rate) is the rate at which gas enters or leaves the lung.

  • Inhalation

The act of taking in breath. Inhalation results from the negative pressure in the lungs caused by contraction of the diaphragm, which causes it to move downwards and to expand the chest cavity. The resulting flow of air into the lungs restores a pressure equal to that of the atmosphere. inhalation.

  • Exhalation

The act of breathing out air. During exhalation, the diaphragm relaxes and moves upward, causing compression of the lungs and an outward flow of air. exhalation.

  • The right lung is slightly larger than the left.
  • Hairs in the nose help to clean the air we breathe as well as warming it.
  • The highest recorded "sneeze speed" is 165 km per hour.
  • The surface area of the lungs is roughly the same size as a tennis court.
  • The capillaries in the lungs would extend 1,600 kilometres if placed end to end.
  • We lose half a litre of water a day through breathing. This is the water vapour we see when we breathe onto glass.
  • A person at rest usually breathes between 12 and 15 times a minute.
  • The breathing rate is faster in children and women than in men.
