Excretory system
The excretory system removes waste and toxins from the human body.
Your skin eliminates waste by sweating.
Your lungs eliminate carbon dioxide.
Your kidneys filter over 180 liters of blood in order to produce urine.
The kidneys filter waste like urea. This liquid that is collected is called urine.
Your kidneys are made up of millions of filtering units called nephrons.

⁣Cornea: The cornea is the clear outer part of the eye's focusing system located at the front of the eye. Iris: The iris is the colored part of the eye that regulates the amount of light entering the eye. Lens: The lens is a clear part of the eye behind the iris that helps to focus light, or an image, on the retina.

⁣Stomata are generally more numerous on the underside of leaves. They provide for the exchange of gases between the outside air and the branched system of interconnecting air canals within the leaf. A stomate opens and closes in response to the internal pressure of two sausage-shaped guard cells that surround it.

⁣Specialised cells are cells designed to carry out a particular role in the body, such as red blood cells which are designed to carry oxygen. Nerve cells help contraction of muscles or the relaxation of muscles according to what specific job you need them to do.

I hope you liked our video.
Kids should spend time watching informative videos and expand their knowledge day by day.
Kids retain what they see in audio-visual lessons so make them watch informative videos rather than cramming things.

If you want to learn any topic, please free to write to us, we will upload the video to help you out as soon as possible.
We can also create a customized u tube playlist for the topics you want to learn.
Your feedback is important to us.

About us:
Welcome to Tutway.
A unique platform where learning is fun.
Now there is no distinction between kids’ fun time and study time.
At Tutway, we believe in a very simple idea that audio-visual learning is the most effective tool for grasping knowledge. Many researchers have proven that kids learn a lot by playing interactive games and watching audio-visual animated lessons as compared to reading from books.

That's when Tutway comes to the rescue.
Tutway is a supplementary education program where kids can learn at their own pace. The students can watch animated videos that are so meticulously made that they can understand even the most complex concepts very easily. There is a question bank at the end of each video where students can answer those questions multiple times and test whether they have grasped knowledge completely or not.
We have information systems embedded in the program where parents can monitor real-time performance of their kids and get up to date information about their performance, including quizzes attempted and the marks got in each quiz, both in tabular and graphical formats. Regular reports are e-mailed to the parents so that the parents can analyze their kids’ performance.
If we want to learn high-level concepts, we should have a clear understanding of the basic concepts. For instance, if kids don't know about addition and subtraction, they cannot do multiplication, and if they don't know about multiplication, they cannot do division, and if they don't have knowledge of these four basic operations, Algebra cannot be done by them, and it goes on and on.
The same applies to the English language if kids don't have sound knowledge of grammar and vocabulary; it becomes extremely difficult for them to have their communication skills.
Knowledge of the scientific concepts is also required for observing physical, chemical, biological phenomena happening all around us.
That is why; Tutway has thousands of animated videos on Maths, English, and Science to clear the basics of these subjects. It perfectly suits most of the educational needs of most of the students, regardless of their learning abilities.
So hurry up, download the Tutway app and book a free demo cl**** to make education interactive and fun experience.

⁣Phonics involves matching the sounds of spoken English with individual letters or groups of letters. For example, the sound k can be spelled as c, k, ck or ch. Teaching children to blend the sounds of letters together helps them decode unfamiliar or unknown words by sounding them out.

Lyrics

A car heading for the borderline.
distance travelled = speed × time
s = v t


You want to measure the acceleration?
acceleration=(change in velocity)/(time taken)
a=(Δ v)/t

Try to build the momentum properly.
momentum = m**** × velocity
p = m v

Turn on the speaker. It’s a song from Eminem.
wave speed = frequency × wavelength
v = f λ

Ain’t nobody as ‘phat’ as me.
weight = m**** × gravitational field strength g
W = m g

I use the force in this rap equation.
resultant force = m**** × acceleration
F = m a

pressure=(force normal to a surface)/(area of that surface)
p=F/A

There’s too much density in this whole tune.
density=m****/volume
ρ=m/V

23 Physics Equations.
We’ll take it one by one so have patience.
23 Physics Equations.
We’ll take it one by one so have patience.


A powerful quarterback runs on the touchline.
power=(work done)/time
P=W/t

Or

power=(energy transferred)/time
P=E/t

If we’re talking about transfers, then check this rhyme.
What football transfer would you like to happen, if you had infinite money to buy?
energy transferred = power × time
E = P t

Another way to get energy transferred, this physics equation I’m spitting.
energy transferred = charge flow × potential difference
E = Q V

My bars. I don’t charge at this current time.
charge flow = current × time
Q = I t

If you want to measure the potential difference.
potential difference = current × resistance
V = I R

Two more power equations all of a sudden.
power = potential difference × current
P = V I

Another equation for power. Sit back and listen.
power = (current)2 × resistance
P = I2 R

Chorus

In a factory, putting of a piston.
work done = force × distance along the line of action of the force
W = F s

You want to know the force applied to a spring?
force applied to a spring = spring constant × extension
F = k e

moment of a force = force × distance normal to direction of force
M = F d
The symbol is M = Fd but you knew that of course.


Efficiency is a mission to me but kinetic energy let’s do first.
kinetic energy = 0.5 × m**** × (speed)2
E_k=1/2 m


efficiecy=(useful output energy transfer)/(total input energy transfer)

Or

efficiecy=(total power output)/(total power input)


That’s 22 equations from your physics book.
One more to do before I spit the hook.

gravitational potential energy = m**** × gravitational field strength (g) × height
Ep = m g h
That’s 23 equations done. Good night.
