Is respiration the same thing as breathing? - MyTutor
The key differences:Breathing is the process of moving air in and out of the lungs - like when you take a breath.Respiration is the reaction, carried out in cells, which produces energy. Further information about breathing:
What is the difference between breathing and respiration?
Breathing is the physical process where you inhale and exhale air in and out of your lungs. Inhaling brings in air containing Oxygen, which is absorbed and exchanged for Carbon Dioxide. The Carbon Dioxide, now in the air inside your lungs, is expelled when you exhale.
Describe how air is moved in to and out of your lungs.
The process of moving air into and out of your lungs is called ventilation, or breathing. Ventilating the lungs is brought about by the contraction and relaxation of the intercostal muscles and the diaphragm, this causes changes in pressure in the chest cavity forcing air …
Explain the process of inhalation - MyTutor
Inhalation is the process of breathing air into the lungs through the nose and mouth. This causes an increase in the volume of air in the lungs, meaning the pressure will decrease. This is acheived using 3 sets of muscles.
Explain the mechanism of breathing - MyTutor
Breathing consists of two phases called inhalation and exhalation. Inhalation. In order for air to be drawn into the lungs during inhalation the volume of the thorax must increase. This is brought about due to the contraction of respiratory muscles. The diaphragm contracts and flattens and the intercostal muscles contract to pull the ribs up ...
Describe the mechanism of mammalian breathing. | MyTutor
The process of breathing is made up of two components: Inhalation; Exhalation; Inhalation is the process of filling the lungs with air. As they fill they expand and so the rib cage moves upwards and outwards. Exhalation is the process where the lungs empty of air. As they empty they shrink back and the ribs move downwards and inwards.
Describe the process of breathing out. | MyTutor
Firstly, the intercostal muscles contract. This causes the ribcage to move upwards and outwards. The diaphragm also contracts.
What is the difference between breathing and respiration?
Respiration, on the other hand, is a CHEMICAL process during which organic (containing carbon) molecules (e.g. glucose) are metabolised (=broken down) in an oxidation reaction (=using oxygen) in order to release energy for our bodies to use. Therefore, breathing is essential for respiration to occur, as it provides the oxygen needed.
Explain the diffusion process of gas exchange in the lung
Explain the diffusion process of gas exchange in the lung during respiration Oxygen and carbon dioxide, dissolved in water, are exchanged by diffusion in the lungs. Blood travelling to the lungs is deoxygenated and instead of oxygen, carbon dioxide is bound to the red blood cells.
Explain the role of the diaphragm in breathing out | MyTutor
The external intercostal muscles contract which moves the diapraghm upwards. This reduces the volume of the thorax and therefore with less space, the pressure in the lungs goes up. The pressure in the lungs will now be higher than outisde and becuase of this difference, air will move out causing exhalation (breathing out).
