Welcome to Chapter 31 :
Overview Of Vertebrates!
In this chapter, we
will be explaning about vertebrates, from the way they evolved, to the different heart structures of each type of vertebrates! And
all the usual special and unique characteristics that all vertebrates have. Click the links on the left to the
desired section! Hope this would be a fun and educational for you!
The Inside Scoop!
Section
1 : Story Of Vertebrate Evolution
The
History of how the amazing vertebrates evolved during the years. Who dominated the land and the sea first? In which order
did they come in? Learn more about these interesting creatures in Section 1!
Section 2 : Challenge Of Obtaining Oxygen
The different ways that different species obtain
oxygen. Keep in mind that not all species of vertebrates have lungs that can be used to inhale oxygen from! Check this section
out to learn more about their structures!
Section 3 : Evolution Of A Better Heart
In order to obtain energey, there would be a neccessary organ to do all this ; that would
be the HEART. Not only do the lungs do all the work, but the heart is also a big part of the body. Each organ helps out another
to carry out the important tasks. In section 3, we will be explaining about the different heart structures of different species.
Section 4 : Challenge Of Retaining Water
Since vertebrates have been known to have evolved in the water, there must have been a period
of time in which they spent most of their lives underwater. So in the section, we will learn more about the evolution of vertebrates
from under water to vertebrates on land. We will also show some of the organs that helped them survive from the balance of
water and salt water.
Section 5 : Reproduction and Developement
In this chapter, the importance of the life cycle is obvious. Without reproduction,
there would not be a continuation of any species. So, in this chapter, we will be talking about how different types of vertebrates
reproduce and the ways they develope into adult hood.
