Answer 1

the human respiratory system consists of organ responsible for taking in oxygen for respiratory in realising carbon dioxide and water vapour which are the waste product formed during respiration the nostrils Ranchi lungs and it right here are the main organ of the respiratory system in a man breeding in the taking of a rich in oxygen into the our body is called inhalation the air around us is ampere hour long require which is most warm and clean as the air we breathe in a parcel to distress it is Mall stand by the synonym of skuast present in a nose musculus is secreted by the lining in the air becomes warm by blood circulating in the nose the most QS and their present inside our nose does dust particle and diseases causing germs and prevent them from entering the respiratory system we don't get clean air if we breathe through our mouth inside of our nose therefore we should always bad to the nose it will protect us from kaycee and infection to the lungs from the nose and nasal cavity the year passes through the short cavity to the wind pipe or trachea the wind pipe inches into two similar tube called the branch each branch was present into a lunch in a lungs each branches branches out into smaller tube called branch e holes at the end of this kids 8 years sex called Olive each lungs contain about 300 million olives the air we breathe in eventually reach is this year sex the sets are surrounded by blood vessels the oxygen present in air we breathe in goes into the blood contained in a blood vessels the carbon dioxide present in blood passes out of the blood into their success does exchange of gases take place in the lungs the blood takes the oxygen to all the cells of the body where it is used to get energy from food the carbon dioxide released by the sales as waste goes back into the blood and is released into the air success of the lungs it is then breath out by the bay giving out of a rich in carbon dioxide it is called acceleration to understand what causes air to go in and out of the Lambs letters perform a simple activity when you breathe in air the diaphragm goes down increasing the space in the chest cavity the Year from the atmosphere enters the lungs and their expend when you break them out the diagrams of decreasing the space in the circuit in these forms the route of the lungs when a person need extra energy for example the various is running the breathing become faster supplier of season 2 the cell this is speed of The breakdown of food does release more energy cellular respiration the blood taken the auction to all the cells of the body body as a substance called hemoglobin which brand itself with oxygen to form a global it is this form that oxygen is carried through the body during respiration occurs in SSLC English speaking Cellular respiration the sugar molecules in a food oxidised to form carbon dioxide and water and energy is given out the reaction involved in oxidation form of glucose is oxidised reduce carbon dioxide and water

Answer 2

Residual air is the small volume of air that remains inside the lungs even after exhalation.

The presence of residual air in lungs constitutes benefits for the lungs such as

- The presence of residual air inside the lungs keeps it or protects it from collapsing after exhalation.

- Due to the presence of residual air inside the lungs, it stays ventilated until the next inhalation.
