Question

Answer

Respiratory Tract in Human Beings

The respiratory system is responsible for respiration that involves the intake of oxygen and the release of carbon dioxide. The human respiratory tract consists of a series of organs and structures that work together to provide oxygen to the body and remove carbon dioxide.

The correct sequence of the respiratory tract in human beings is as follows:

- Nose: The respiratory tract starts with the nose, which is the primary organ for breathing. The nose filters, warms, and moistens the air before it enters the body.
- Pharynx: The air passes through the pharynx, which is a muscular tube that connects the nose and mouth to the larynx and esophagus.
- Larynx: The air then passes through the larynx, which is also known as the voice box. The larynx contains the vocal cords and helps in producing sound.
- Trachea: The air then enters the trachea, which is a tube-like structure that connects the larynx to the bronchi. The trachea is also known as the windpipe.
- Bronchi: The trachea divides into two bronchi, which are two branches that lead to the lungs.
- Bronchioles: The bronchi further divide into smaller branches, known as bronchioles.
- Alveoli: The bronchioles end in tiny air sacs called alveoli, which are surrounded by blood vessels. The exchange of oxygen and carbon dioxide occurs in the alveoli.

Therefore, the correct sequence of the respiratory tract in human beings is Nose - Pharynx - Larynx - Trachea - Bronchi - Bronchioles - Alveoli. Option B is the correct answer.

Answer

The correct sequence is

Nose - Pharynx - Larynx - Trachea - Bronchi - Bronchioles - Alveoli

Answer

Answer should be b bcoz nose open into pharynx and pharynx, which is common passage for food and air open into larynx and larynx into trachea then trachea extend up to mid thoracic cavity and divide into left and right bronchi and bronchi leads to secondary teritary  bronchiole and it lead to thin irregular wall like structure known as alveoli

Answer

B

Answer

Option b

Answer

A

Answer

Correct answer is B... nose - pharynx -larynx - trachea-bronchi-bronchioles -alveoli

the question is from std 11th biology NCERT... breathing and exchange of gases topic... respiratory system, physiology...

explanation : in respiratory tract.... air passes through
nose ( external nare ) -- nasal cavity -- internal nare --- pharynx --- larynx ( sound box ) --trachea (windpipe ) ---bronchi ---- bronchioles ---alveoli

Answer

The answer is B.

Answer

Options b is the correct answer

Answer

Obtion b

Answer

Answer b
part-1 The respiratory system- the respiratory system organs helps in breathing process. includes nasal airways ( nose,pharynx,larynx, and trachea) lungs ( having alveoli), blood vessels for gaseous exchange.

it helps body to exchange CO2 and O2 between air and blood.

part-2. The Air passage- air enters respiratory system through nostrils and goes into nasal chamber. air then travels into pharynx and then larynx. larynx present above trachea which results in air transferring to trachea or windpipe.

part-3 conclusion - air moves from nose towards alveoli .

Answer

Correct optn=b)
Coz. nose then pharynx which is coman opening for respiratory and digestive tract. then comes larynx which is also known as voice box.then trachea (wind pipe) then bronchi (the passageways that connect your windpipe to your lungs)then comes small branches of bronchi known as bronchioles and then alveoli which exchange co2 and o2

Answer

A part

Answer

Optn B

Answer

Answer should be b

Answer

Nostrils-nasal cavity- pharynx- larynx- trachea- bronchi - bronchioles- alveoli

Answer

Air is move from nose and pass through pharynx move thrown from larynx and go to trachea and move to bronchi and it's have two bronchioles in that alveoli is present
