In insects, air enters the body through
In insects, air enters the body through spiracles present on lateral sides of body as small opening.
During exhalation, the ribs move
The process of releasing air during respiration is called exhalation. During exhalation, the ribs move downwards to reduce the volume of thoracic cavity.
Plants breathe through their stomata located in their
Stomata are small openings on the leaves surface through which exchange of gases takes place in plants.
Gills are respiratory organs in
Gills are respiratory organs in fish. Gills intake oxygen from water.
Breathing is a
Breathing may be defined as the process of taking in oxygen from the environment and giving out carbon dioxide So, breathing is just a physical process in which no energy is released. On the other hand, the process of respiration is more complex. It involves the inhalation of air, absorption and transport of oxygen to various cells of the body, oxidation of food in the cells and elimination of carbon dioxide from the body. Thus, respiration is a biochemical process. During the process of respiration energy is released which is used for performing various biological activities and maintenance of life.
In anaerobic respiration which chemical substance is produced?
The products of anaerobic respiration are lactic acid,Alcohol,carbon dioxide, and water. Anaerobic respiration is the breakdown of glucose in the absence of oxygen.
Blood is red coloured due to presence of
Blood is red coloured due to presence of haemoglobin pigment that carries oxygen.
Inhalation is the
The part of breathing during which oxygen rich air is taken in is called inhalation.
More energy is released in
During aerobic respiration, complete oxidation of food takes place and more energy is released in form of ATP.
The opening of the pharynx to larynx is guarded by
Pharynx opens in larynx through glottis which is guarded by a leaf like unpaired cartilage which is called epiglottis. It prevents the entrance of food into trachea.
