hello friends this video on tissues part 12 is brought to you by exam feel calm no more fear from exam now let us look at the different types of connective tissue so far we saw what is connective tissue what are what how does the structure of a connective tissue looks like so now we will talk about the different types of connective tissue which we are going to study in detail in the next few slides for the first connective tissue which we will talk about this blood the next one would be the support tissue now even inside connective tissue we have broadly classified them into few types so the one who is black so that is considered as a separate connective tissue then we have support tissue there are certain connective tissue whose main function used to provide support so under that category falls bone and cartilage then we have Ben's connective tissue and loose connective tissue dense connective tissue as the name says it is very dense that means maybe it is it has more fibers in the extracellular matrix the proportion of fibers is more and when compared to the ground substance so dense connective tissue are also sometimes known as fibrous connective tissue because there is more of fibers so under this category falls the ligament and the tendon so these ligaments and tendons help in joining bone to bone and bone to muscle so these are dense connective tissues then we have used the negative tissue under which we will talk about a roller tissue and adipose tissue so loose connective tissue in a very similar fashion it will have lot of lot of but at least it will have some empty spaces that means in hair like in dense connective tissue we have more of I births in this case the ground substance also plays a role in case of loose connective tissue so these are some of the types of connective tissue which we are going to discuss in this lesson so let us start our discussion with blood so blood is a fluid connective tissue so the question here is why is blood a connective tissue because you might be wondering that when connective tissue is something which joins things for example bones tendons ligaments that is quite convincing but why is blood a connective tissue what is it connecting we will see that now blood consists of one who 78% of water and 22% of solids so this is the composition now since blood connects different systems of the body by transporting gases digested food hormones and waste materials to different body parts that is why blood is considered as a connective tissue what is a connective tissue a tissue that connects different body parts so if you look at blood what does it do it actually helps in transporting food or waste materials from one part of the body to another for example the place where excretion has to happen it will take the waste materials and throw it there the two the different body parts which needs food it will transfer it there it will transport gases to different parts of the body hormones and other chemicals so it actually connects different parts of the body and that is why blood is gana considered as a connective tissue right so if you look at it just see how blood connects different body parts so blood is flowing everywhere well so it is actually connecting all the different parts of the body so now let us look at the different blood components so what are the different components which make up blood now like every connective tissue has a matrix similarly blood also has a matrix because that was the general structure of any connective tissue so whichever connective tissue we will now talk about we learned bone cartilage or tendons everything will have a matrix and they will also have some cells embedded in that matrix so in case of blood what does that extracellular matrix the extracellular matrix in case of blood is known as plasma or it is also sometimes also known as blood plasma so it is a fluid matrix on which blood cells are embedded right so the basic step will remain the same you have one matrix in that manhoods you have the cells embedded let matrix is made up of fibers and ground substance so that will remain the same just that in some connective tissue the matrix the nature of the matrix will be little different in somewhere else it will be subjective level so in case of blood the extracellular matrix is plasma which is a fluid matrix now what are the cells that are embedded in matrix the blood cells there are many different types of cells which are embedded in the plasma so what are the different types of cells the first one is RBC that is red blood cells these are small cells without nucleus so you can see in this picture also they are showing those RBC's that is the red blood cells which are small cells without nucleus so this is a point to remember that these cells and without nucleus they carry oxygen from lungs to different parts of the body so this is the function of the red blood cells because as I said by blood helps and transportation now every component of blood have a specific function for example RBC will carry oxygen from lungs to different parts similarly the next component that is WBC which is also quite as white blood cells what are they these are nucleated cells that means these are the cells with nucleus what do they do they help fight infection and builds that body's immune system so what is immune system now for inside the body of every individual we have a immune system which by itself fight against infections for example sometimes it might happen that some infection is entered your body by any means okay so it will try to disturb your body but there is by default an immune system of the body which will try to fight that infection now if the immune system wins you do not fall in at all but if the immune system fails then you fall in because the infection wins in that case and it infects your body and you fall in so these white blood cells make up the immune system they fight with the infection and thus protect our bodies from getting infected easy these white blood cells leave for three to four days in human body so their longevity is ready let's stay alive only for three to four days after which they die and then again new WBC's are formed so the formation and the completion of WBC's keep happening very frequently and the third component is platanus what a flatulence these are smaller in size when compared to the red blood cells and WBC's they help in blood clotting after you ever seen that when when you get a cut somewhere in your finger or summin what happens it starts really learn starts coming out but is it that the blood keeps keeps on coming out forever it is not like that after some time the blood clots right and that is where the black olives play its role so the black olives help in blood clotting therefore it prevents excessive bleeding from a person's body because if for a small cut too much of blood comes out of your body it becomes the body pick it becomes to be because there is very less blood left inside the body so platon it's helped in blood clotting so these are the three main components of blood that is red blood cells w DC that is white blood cells and the blood plantlets right so now you understood the structure of blood order how is the structure of blood look like so blood will have an extracellular matrix which is called plasma in that glaze m'a are embedded RBC's WBC's and platanus now RBC WBC and platitudes they have their own functions like RBC will carry oxygen from lungs to different parts WBC will fight with the infection and planets will help in blood clot again structurally also there are all different RBC's are without nucleus WBC's are with nucleus and that it's are very small in size when compared to the IVC S&W disease now when I talk of WBC's here you can see that the picture in the picture there are so many different types of issue with all different names so these are the different components of WBC so even inside WBC you have many different types let me draw a your Sinovel ways of the lymphocyte and monocyte but at present we are not going into the detail of all these different types of WBC's because this is something which you study in your higher classes so for now whatever information is given is enough another important question that might strike your mind is why is this WBC known as white blood cells because of a red blood cells it is convincing because the blood is red in color so maybe that's why it is called red blood cells but why white blood cells that is because I'm taking a small blood sample and doing a centrifugation of that sample it was seen that a white layer of nucleated cells was seen between the RBC's and the blood plasma and because of that white appearance of the nucleated cells they are known as white blood cells so under the microscope when that blood sample was seen it was seeing that there was lead to asthma there was red blood cells they were all red in color but there was a white layer of nutrients and the nucleated cells cannot be red blood cells so the nucleated cells which were white in color were termed as white blood cells so I think we are good thank you please visit www.payoor.com to watch more videos attempt free online test get free study material find tutors and mentors thank you once again
