Respiratory

Question 1

a vital part of our body that
helps us breathe. It is made up of organs like the nose,
mouth, windpipe (trachea), airways (bronchi and
bronchioles), lungs, and tiny air sacs called alveoli.

Answer 1

respiratory system

Question 2

Its main function is to take in oxygen from the air we
breathe and release carbon dioxide, which is a waste
product.

Answer 2

respiratory system

Question 3

protect our
body from germs and other particles in the air

Answer 3

respiratory system

Question 4

Organs of the respiratory system

Answer 4

Nose and Nasal Cavity
Pharynx (throat)
Larynx (voicebox)
Trachea (windpipe)
Bronchi (airways)
Lungs
Diaphragm

Question 5

warm and moisten incoming air. They also house olfactory receptors responsible for the sense of smell

Answer 5

Nose and Nasal Cavity

Question 6

serves as a passage for both air and food. It plays a role in swallowing and directing air into the trachea

Answer 6

Pharynx (throat)

Question 7

contains the vocal chords, which vibrate as air passes through, producing sounds for speech

Answer 7

Larynx (voicebox)

Question 8

a tube-like structure made of cartilage rings that transport air from the larynx to the lungs. Its walls are lined with cilia and mucus, which help trap and remove foreign particles.

Answer 8

Trachea (windpipe)

Question 9

They further divide into smaller brochioles, eventually reaching the alveoli

Answer 9

Bronchi (airways)

Question 10

The primary organs of respiration. They are sponge-like structures containing millions of tiny air sacs called alveoli, where gas exchange occurs. Oxygen from the air is absorbed into the bloodstream,, and carbon dioxide is released from the bloodstream into the alveoli to be exhaled.

Answer 10

Lungs

Question 11

A dome-shaped muscle located below the lungs, plays a crucial role in breathing. When it contracts, it flatterns,, increasing the volume of the chest cavity and causing inhalatioon. When it relaxes, it returns to its dome shaped, decreasing the volume of the chest cavity causing exhalation.

Answer 11

Diaphragm

Question 12

Located at the Lining of the respiratory tract, including the nasal cavity, trachea, bronchi, and bronchioles

Answer 12

Epithelial Tissue

Question 13

Acts as a protective barrier against pathogens,
allergens, and foreign particles entering the
respiratory system

Answer 13

Epithelial Tissue

Question 14

Secretes mucus to trap debris, microbes, and
other particles, preventing them from reaching
the lungs

Answer 14

Epithelial Tissue

Question 15

Contains cilia that sweep mucus and trapped
particles out of the respiratory tract, aiding in
their removal

Answer 15

Epithelial Tissue

Question 16

Located throughout the respiratory system,providing structural support to various components

Answer 16

Connective tissue

Question 17

Maintains the shape and integrity of the airways, preventing collapse during breathing

Answer 17

Connective tissue

Question 17

Supports blood vessels, nerves, and other structures within the respiratory tract.

Answer 17

Connective tissue

Question 18

Allows for elasticity and recoil of the lung tissue, facilitating movements.

Answer 18

Connective tissue

Question 19

Located in the Smooth muscle in the walls of the bronchi and bronchioles

Answer 19

Muscle tissue

Question 20

Regulates the diameter of the airways controlling air flow into and out of the lungs

Answer 20

Muscle tissue

Question 21

Constricts during conditions like
asthma or allergies, leading to airwaynarrowing

Answer 21

Muscle tissue

Question 22

Dilates to increase airflow during
periods of increased demand,such as exercise

Answer 22

Muscle tissue

Question 23

Nerves innervating respiratory muscles and control centers in the brainstem

Answer 23

Nervous tissue

Question 24

Controls breathing rate and depth, adjusting in response to changes in oxygen and carbon
dioxide levels in the blood

Answer 24

Nervous tissue

Question 25

Coordinates the contraction and relaxation of respiratory muscles during inhalation and
exhalation.

Answer 25

Nervous tissue

Question 26

Sensory perception of lung function, detecting irritants and triggering protective reflexes like
coughing or sneezing.

Answer 26

Nervous tissue

Question 27

These cells line the respiratory tract and serve as a protective barrier againts pathogens and foreign bodies. They also produce mucus which helps trap and remove these particles from the airways.

Answer 27

Epithelial Cells

Question 28

These cells are gound in the repiratory tract and are covered in hair-like structure called cilia. The cilia beat in a coordinated fashion to move mucus and trapped particles upward and out of the airways, a process knows as mucociliary clearance.

Answer 28

Ciliated cells

Question 29

These cells are thin, flat cells that make up the walls of the alveoli, the tiny air sacs in the lungs where gas exchange occures. Their thin structure allows for efficient diffusion of oxygen and carbon dioxide.

Answer 29

Alveolar type 1 cells

Question 30

These cells secrete sufactant, a substance t hat reduces surface tension in the alveoli and prevents them from collapsing. Surfactant is crucial for maintaining lung function and preventing resporatory distress syndrome in premature infants.

Answer 30

Alveolar type II cells

Question 31

These are immune cells that engulf and digest pathogens, dead cells, and other debris in the lungs. They play a critical role in the i mmune defense of the repiratory system

Answer 31

Macrophages

Question 32

Contribute to the production of surfactant (reduces tension in the narrow lumen of the respiratory portion of the airway), detoxifies air and may differentiate in bronchial epithelial cells to replace older cells.

Answer 32

Non-ciliated cells

Question 33

Are specialized cells in the alveoli responsible for gas exchange.

Answer 33

Pneuomecytes

Question 34

These cells are found in the epithelium lining of the respiratory tracts. They serve as progenitor cells, capable of differentiating into various types of epithelial cells, including ciliated cells and goblett cells. They play a crucial role in the repair and regeneration of the respiratory epithelium following injury or infection.

Answer 34

Basal Cells

Question 35

occurs as the intrathoracic pressure is reduced through the contraction of diaphragm and the external intecostals muscles and the movement of air into the lungs

Answer 35

Inspiration

Question 36

Occurs as the inpiratory muscles are relaxed and the diaphragm and rib cage rebound to their original positions

Answer 36

Expiration
