RESPIRATION -Important Points -One Liners For Exams
1- The microscopic air sacs present in lungs are called alveoli
2- We will find vocal cards in larynx
3- Lungs are protected by two layers called pleura
4- No of lobes present in the left lung of man are two and in the right lung three
5- In males diaphragm plays important role in respiration, where as
ribs in females.
6- Human physiology written by John Daper
7- Pharynx is a common passage of digestive and respiratory system.
8-Gaseous exchange takes place within the lungs by diffusion
9- A flap like muscular valve controls movement of air and food is
epiglottis
10- Normal shape of diaphragm is dome.
11- The total lung capacity of human is 5800ml
12-The energy currency (ATP) is stored in mitochondria (power houses of the cell)
13-Each ATP (adenosine tri Phospate) molecule gives 7200 calories of energy.
14- Iron (Fe) is present in the haemoglobin where as Magnesium Mg in chlorophyll
15- Accumulation of lactic acid due to strenuous work results muscular pain.
16- In prokaryotic cells respiration occurs within the cytoplasm
17- Production of ethanol during anaerobic respiration by yeast is called fermentation
18- Cellular respiration occurs in mitochondria where carbohydrates get oxidized.
19- Cellular respiration in prokaryotes takes place in cytoplasm
20- Mangrove trees respire with their Arial roots (root hairs)
21- Insects (cockroach, grasshopper) respire through tracheal respiratory system.
22- Fish respire through gills (bronchial respiration)
23- Respiration through skin (Ex. Frog, Earth worm) is called Cutaneous respiration
24- In amoeba, hydra and planarians respiration occurs through diffusion
25- Gaseous exchange takes place in plants through stomata (leaf), lenticels (stem)
