Answer 1

Answer 1 :

● Mouth :

• Mouth is also known as oral cavity.
• It is the secondary external opening for the respiratory tract.

● Nose :

• Nose allows the entry of the air.
• It helps to filter the air we inhale.

● Pharynx and larynx :

• Pharynx are are muscular tube which acts as a passage way for air.

● Diaphragm :

• Diaphragm contracts and expands the lungs.

● Lungs :

• Lungs allows us to breathe.
• It helps oxygen to enter the RBC in blood.

Answer 2 :

Various parts which are found in lungs are upper lobes, lower lobes, bronchi, alveolar ducts. Alveoli are found in lungs which are bubble like structures.

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Answer 3 :

The chief respiratory organs are nose, mouth, pharynx, larynx, diaphragm and lungs. Each chief organ plays an important role in respiration. Each organ have specific functions.

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Answer 4 :

The various parts found in larynx are glottis, subglottis and supraglottis.

• Glottis is a opening of pharynx and it directly open in larynx.

Answer 5 :

The component of food oxidised to produce energy is glucose.

• Glucose formula is C6H12O6.
• Glucose is oxidised to energy during the process of respiration.

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

Answer 6 :

Heat energy is produced at the end of respiration.

• Respiration is also known as exothermic respiration because it produces heat energy.

Answer 2

Question 1:-

Name the structures found in the respiratory system.

AnSwEr:-

1) lungs:- lungs are largest organs of the respiratory system. they allow our body to breathe and oxygen to get in our body.

2) pharynx:- it is a tube like structure which connects the nasal cavity and back of mouth to the throat and larynx.

3) larynx:- larynx connects our pharynx and trachea and it also to conduct air through the respiratory system.

4) trachea:- the trachea (also known as wind pipe) is the widest passage in our respiratory system. it connects larynx to lungs for passage of air.

Question 4:-

name the various parts found in larynx.

AnSwEr:-

(i) glottis:- it is the area of the vocal cords.
