Respiratory System

The middle part of the pharynx is called as oropharynx. The upper part is called as nasopharynx. The lower part is called as larynopharynx. What you see after depressing the tongue is oropharynx.

Since we were born, all vital functions are managed by the Central Nervous System as an involuntary commandment. Bowels movement, heart pulsing, breathing, remain active throughout our lives. In the CNS there are specialized sectors commanding respiration, heartbeat, bowels movement. Our body doesn't need knowing that we have to breathe, but a part of our body, the brain,through the CNS, know that we can't stop breathing.

Each lung is covered with an enclosed membrane called the pleura. The pleura consists of two layers: the visceral pleura, which directly covers the lung tissue, and the parietal pleura, which lines the chest wall. The space between these two layers, known as the pleural cavity, contains pleural fluid that reduces friction during breathing and helps maintain pressure for lung expansion.

the air enters the bronchioles, and into the aveoli, which are small, one cell-thick sacks of air. These sacks are surrounded by tiny capillaries, which is how your blood retrieves its oxygen. From here, the oxygenated blood is carried back to the heart through the pulmonary vein and pumped into your body.

It connects the pharynx with the trachea.

Blood picks up oxygen and releases carbon dioxide in the lungs.

Respiratory acidosis is caused by any condition that interferes with the ability of the lungs to exchange gases, specifically to remove carbon dioxide from blood. And there is an elevated carbon dioxide level in blood with acidosis.

Hyperventilation

lungs

The ciliated lining of the trachea and other tubes of the respiratory tract sweeps impurities up away from the lungs and towards the throat.

The function of alveoli is to exchange gases: oxygen is taken into the blood and carbon dioxide leaves the blood by diffusion across the alvoelar wall. If the alveoli were covered with mucus this would reduce the diffusion of gas molecules between the air and the blood. As there is no mucus, there is no need for cilia either, which Cary out the function of moving cilia out of the respiratory system.

The heart and the Lungs. The heart transfers the blood to the lungs where recently breathed in air will oxygenate the blood, they go from there throughout the body providing oxygen to limbs and the brain along with all the other organs and body parts.

Abnormal development or growth of tissue, organ or cells.

There are tiny hairs called Cilia which lines the airway. Possibly this is what you are thinking about. These tiny hairs trap dirt particles in the air and move them out of the lungs.

Atmospheric (external) air contains a high percentage of oxygen and nitrogen whereas alveoli gas contains a lower percentage of oxygen and a higher percentage of carbon dioxide. The differences in composition are due to the fact that gaseous exchange is taking place within the alveoli in the lungs. Oxygen is diffusing from the alveoli into the pulmonary artery and carbon dioxide is diffusing back into the alveoli from the pulmonary artery due to the concentration gradients. This is the main reason why external air and alveolar gas have such different compositions.

Another reason why the gas compositions are different is due to the fact that alveoli gas contains a mixture of both atmospheric air which has been inhaled and 'old' air which stays in the respiratory track and is not exhaled after each breath therefore giving it a different composition.

Alveolar gas has a larger percentage of water vapour than atmospheric air due to the fact that air is being warmed and moistened as it travels into the respiratory track. This is done by the mucus in the nasal cavity as the air travels past it.

Diaphragm is not part of respiratory system but part of muscular system but it helps in breathing movements .
