Keywords

💡Heart

The heart is described as the most special muscle in the human body, situated between the lungs and slightly to the left of the chest's center. It is a muscular organ responsible for pumping blood throughout the body via the circulatory system. In the video, the heart is likened to a pump, emphasizing its role in sending blood all over the body to deliver oxygen and nutrients to cells, which is essential for life.

💡Blood

Blood is the fluid that circulates in the heart and blood vessels, carrying oxygen and nutrients to the body's cells. The video explains that blood is deoxygenated when it first enters the heart and then is oxygenated in the lungs before being pumped to the rest of the body. This process is crucial for maintaining life as it ensures cells receive the necessary elements to function.

💡Atrium

The atrium refers to one of the two upper chambers in each half of the heart. The right atrium receives deoxygenated blood from the body, while the left atrium receives oxygenated blood from the lungs. In the video, the process starts in the right atrium, highlighting the sequential flow of blood through the heart.

💡Ventricle

The ventricles are the two lower chambers of the heart, with the right ventricle pumping deoxygenated blood to the lungs and the left ventricle pumping oxygenated blood to the rest of the body. The video script describes how blood moves from the atria to the ventricles and then is pumped out to its respective destinations.

💡Valves

Valves in the heart are like doors that control the flow of blood, ensuring it moves in one direction. The video mentions that there are four valves in the heart, which open to let blood in and close to prevent it from flowing back. This mechanism is critical for the proper functioning of the heart.

💡Oxygenated blood

Oxygenated blood is blood that has a high oxygen content, which is essential for delivering oxygen to the body's cells. The video explains that blood is oxygenated in the lungs and then sent back to the heart, where it is pumped to the rest of the body. This process is vital for cellular respiration and energy production.

💡Circulatory system

The circulatory system is the body's network of blood vessels and the heart, responsible for transporting blood, oxygen, and nutrients throughout the body. The video emphasizes the heart as the engine of this system, highlighting its importance in maintaining health and life.

💡Arteries

Arteries are blood vessels that carry oxygen-rich blood away from the heart to the body's organs and tissues. The video mentions arteries as part of the blood vessels that transport blood, indicating their role in the distribution of oxygen and nutrients.

💡Veins

Veins are blood vessels that return oxygen-depleted blood back to the heart. The video script describes veins as taking blood low in oxygen back to the heart, completing the circulatory loop and allowing for reoxygenation.

💡Capillary vessels

Capillary vessels are the smallest blood vessels that connect arteries and veins, facilitating the exchange of oxygen, nutrients, and waste products between the blood and body cells. The video briefly mentions capillaries as part of the intricate network that supports the body's needs.

💡Physical exercise

Physical exercise is any activity that increases heart rate and strengthens the heart muscle. The video provides a tip to take care of the heart by engaging in physical exercise, which is important for maintaining cardiovascular health and overall well-being.

hello friends welcome to new happy

learning video

today we're going to get to know the

engine in our body

today we're going to get to know

the human heart

[Music]

the heart

is the most special muscle we have

it's situated a little to the left from

the center of our chest

between our lungs

and is in an oblique position

positioned diagonally

we say that it's very special because it

sends blood all over our body

[Music]

blood delivers oxygen and nutrients we

need to live to all of our cells

[Music]

a heart is a type of pump

like the ones we use to inflate the

wheels on our bikes

the only thing is that instead of

pumping air it pumps blood

the heart is divided into two parts

the right part

and the left part

separated by a cellular wall so they are

not connected internally

each one of these parts has two chambers

or cavities the upper cavities are

called right

and left atrium and the lower cavities

are called right and left ventricle

the heart also has four kind of doors

which are called valves

these valves open to let's blood in

and they close so this blood can't go

back

now we've got to know the most important

parts of the heart but

do you know how it works

it all commences in the right atrium

where the deoxygenated blood meaning it

has very little oxygen and nutrients

enters the heart

then it goes through the first valve up

to the right ventricle

once it is here the heart sends the

blood directly to the lungs

and it's in this moment where the blood

is oxygenated

and it's filled with oxygen and

nutrients

when it is already oxygenated it goes

back to the heart reaching the left

atrium

from where it will pass through the

third vowel until the last cavity the

left ventricle

finally the heart sends this now

oxygenated blood through the fourth and

last valve

towards the rest of the body

and it starts again

to understand how our heart beats we

only need to imagine that our hand is a

heart and that's when it opens up it

fills up with blood

and when it's closed it pumps that blood

outwards

[Music]

when blood exits our heart it flows

through a whole body through blood

vessels and there are three types

arteries

veins

and capillary vessels

arteries deliver oxygen and nutrients

rich blood to all our organs in our body

veins take that blood low in oxygen back

to the heart

and the capillary vessels

which are very small connected arteries

with veins and cells

fun fact

do you know approximately how much a

human heart weighs

well

it's

450 grams almost half a kilo

the truth is that the heart is the

engine in our circulatory system and is

an incredibly strong muscle

it's able to beat more than a hundred

thousand times a day

so cool

we can't say goodbye without giving you

a tip

we need to take care of our heart and

that's why we need to do physical

exercise we need to eat healthy foods

and please

never ever smoke

[Music]

it's the worst thing you can do to hurt

your heart

goodbye friends see you in the next

happy learning video
