Keywords

💡Respiratory System

The respiratory system is a biological system consisting of specific organs and structures that allow for the process of respiration. In the context of the video, it is the key system that facilitates breathing, which is essential for life. The script explains that the respiratory system uses the lungs and airways to carry out the process of inhaling oxygen and exhaling carbon dioxide. It is crucial for the body to function properly, and its health is directly impacted by the quality of the air we breathe.

💡Inhalation

Inhalation is the act of drawing air into the lungs. It is the first phase of the breathing process, during which oxygen-rich air is taken into the body. The video script describes inhalation as the phase when air enters the lungs, highlighting its importance in the respiratory process. It is a vital step for oxygen uptake, which is necessary for cellular respiration and energy production.

💡Exhalation

Exhalation is the process of expelling air from the lungs. It is the second phase of breathing, where carbon dioxide, a waste product of cellular respiration, is removed from the body. The script mentions exhalation as the phase when the air we don't use is expelled, emphasizing its role in maintaining a healthy balance of gases within the body.

💡Oxygen

Oxygen is a chemical element that is essential for life, as it is required for cellular respiration. In the video, oxygen is described as a component of the air that we inhale, which is then used by our cells to produce energy. The script emphasizes the importance of oxygen by illustrating how it is taken into the body through the respiratory system.

💡Carbon Dioxide

Carbon dioxide is a waste gas produced during cellular respiration. The video script explains that carbon dioxide is expelled from the body during exhalation, which is a critical process for maintaining a healthy internal environment. The buildup of carbon dioxide can be harmful, so the respiratory system's ability to remove it is essential for good health.

💡Airways

Airways refer to the passages through which air travels to reach the lungs. The script outlines the components of the airways, including the nose, mouth, pharynx, larynx, trachea, bronchi, and bronchioles. These structures are essential for the respiratory system to function, as they facilitate the movement of air in and out of the lungs.

💡Lungs

The lungs are the primary organs of the respiratory system, where the exchange of oxygen and carbon dioxide takes place. The video script describes the lungs as the site of gas exchange, where oxygen from the air is transferred to the blood, and carbon dioxide is moved from the blood to be exhaled. The health of the lungs is crucial for the respiratory system to work effectively.

💡Pharynx

The pharynx, or throat, is a part of the airway that connects the nasal and oral cavities to the larynx. In the video, the pharynx is mentioned as a passage for air to travel through during the breathing process. It plays a role in both respiration and swallowing, making it an essential component of the respiratory and digestive systems.

💡Larynx

The larynx, or voice box, is a part of the respiratory system that also contains the vocal cords. The script explains that the larynx is where the vocal cords are located, which are responsible for producing sound when they vibrate, as in speaking or singing. The larynx is a crucial component of both the respiratory and vocal systems.

💡Bronchi

Bronchi are the main airways within the lungs that branch off from the trachea. The video script describes how the trachea divides into two bronchi, which further branch into smaller tubes called bronchioles. The bronchi are essential for directing air into the appropriate parts of the lungs for gas exchange to occur.

💡Alveoli

Alveoli are tiny air sacs in the lungs where the actual gas exchange occurs. The script mentions that oxygen passes from the air in the alveoli into the blood, and carbon dioxide moves from the blood back into the alveoli to be exhaled. The alveoli are critical for the respiratory system's function, as they increase the surface area available for efficient gas exchange.

Highlights

Breathing is an involuntary process that we do without realizing but can control it.

Breathing consists of inhaling oxygen-rich air and exhaling carbon dioxide.

Inhalation is the phase when air enters the lungs, while exhalation is when we expel unused air.

The respiratory system uses the lungs and airways to facilitate breathing.

Airways include the nose, mouth, pharynx, larynx, trachea, bronchi, and alveoli.

The larynx contains vocal cords, which allow us to speak and sing.

The trachea is divided into two tubes called bronchi, which lead to the lungs.

Hello friends we all know that in order

to live we have to breathe and to carry

out this very important function we use

the respiratory system

[Music]

breathing is an involuntary process that

we do without realizing but we can

control it today we're going to find out

what breathing consists of and how the

respiratory system

works the first thing we need to know is

that breathing consists of inhaling air

in

nature to take advantage of the oxygen

it

contains and thereby expelling the

carbon dioxide

which is the part of the air we don't

[Music]

use the first phase which is when the

air enters the lungs is called

inhalation the second phase which is

when we expel the air we don't

use is called

exhalation they are the exact

[Music]

opposite there respiratory system is

responsible for

breathing and for that it uses the

lungs and the Airways which are the

parts that compose

it the Airways are tubes through which

the air passes until it reaches the

lungs and they are made up of the nose

and

mouth the FNX

the larynx the

traa the

broni the

bronchial and the

alvioli now let's take a look at how the

respiratory system

works when we breathe in air enters our

body through our nose and

mouth the air then passes through the

far and into the

larynx did you know that the larynx

contains the vocal cords which allow us

to speak or sing la la la la la they are

like the strings of a

[Music]

guitar when they vibrate they produce

the voice well once the air has passed

through the larynx it reaches the traa

the traa is divided into two tubes

through which the air passes which are

called the

broni the broni once inside the lungs

Branch into narrower tubes called

bronchials and each Broncho

leads into many small sacks called

alvioli and it is there in the alvioli

where gas exchange takes

place the oxygen in the air passes into

the blood through some very small blood

vessels which are called

alvioli then what is left over from the

air which is carbon dioxide travels back

through the respiratory system to be

expelled outside

[Music]

as you can see the respiratory system is

very important so we have to take good

care of it and for that we have to

practice a lot of sport and take care of

nature so as not to pollute the air we

breathe healthy lungs are pink but when

we breathe in tobacco smoke SM or when

the air is very

polluted they turn brown and stop

working

properly when this happens we get tired

without doing

anything and we start to feel really bad

it's certainly not very smart to damage

our lungs don't you

think so make sure you do lots of

physical exercise and remember

never ever smoke to ensure that your

lungs will always be very

healthy and that you will always be very

happy goodbye friends see you in the

next
