Answers
Answer:
1. Nares
2. Primary Bronchi
3. spiracles
4. cell membrane. (not sure)
5. Gills
6. Inhalation
7. Antenna (specially found I arthropod insects)
8. capillaries (located in the wall of alveoli)
9. Adenosine Triphosphate
10. The very special dome shaped muscle located below the lungs in a human body is the major muscle of respiration , it create beats rhythmically and continuously
based upon the inhalation .
1. Nostrils
2. Bronchi
3. Spiracles
4. Unicellular oranisms do not have any respiratory system, Oxygen enters in body through diffusion.
5. Gills
6. The taking in of air rich in oxygen in to the body during breathing is called Inhalation & giving out of the air rich in carbon dioxide is called Exhalation. Therefore, a breath means one inhalation plus one exhalation.
7. Antenna are the special organs which are only found in insects ( arthropods ) but not in any other group of animals.
8. Gas exchange is the delivery of oxygen from the lungs to the bloodstream, and the elimination of of carbon dioxide from the blood stream to the lungs. It occurs in the lungs between the alveoli and a network of tiny blood vessels called capillaries, which are located in the walls of the alveoli.
9. Adenosine tri - phosphate
10. The diaphragm, located below lungs, is the major muscle of respiration. It is a large, dome - shaped muscle contracts rythmically and continuity, and most of the time, involuntarily. Upon inhalation, the diaphragms contracts and flattens and the chest cavity enlareges.
