Tendons and Ligaments

What makes our bones stay together? Well in our body there is a special rubber band that makes our bones stay together and that is called a ligament. Ligaments attach our bones together so we can bend and do all other kinds of stuff. Ligaments are really helpful too, but why is that. Well think if we had one long bone on our arm would we be able to be able to bent our arm, no that’s why we need our ligament so they can help us and our bones and joints move. But joints need our ligaments more so your joints can make us move. Also what makes are muscles connect to our bones? There is a special name for that and those are your tendons. Tendons are the end of the muscles and they connect to your bones. Did you know that the biggest tendon in our body is Achilles and your Achilles location in the body is the heel? Do you know how you injure you tendons? Well the way you injure your tendons is when you pull your tendons but what does that mean. Pulling a tendon means that when you are doing something on Physical Education and you don’t stretch you can pull your tendon .  Did you know that you tendons are very different from your muscles because your tendons can not stretch the same way as your muscles. Even there is another injury for your tendons and that is called Tendonitis. Tendonitis is cause by certain things you do and they are either typing, piano or string instruments, but what happens is when you get tendonitis your tendons get inflamed and swollen and when you move one of your tendons when have tendonitis your tendons will be painful. So always remember to protect your tendons and ligaments.   

Different parts of the blood

Do you know what makes our blood? Well there are several parts of your blood and they are called Plasma, White Blood Cells, Red Blood Cells and Platelets. Plasma is what makes your blood into liquid and makes your white blood cell and red blood cells travel around your body too. White blood cells are what makes you better when you get sick which means-- your white blood cells fight your germs, but your white blood cells need energy to fight your germs and that is sleeping. If you go to sleep your white blood cells can fight your germs in your body, if you don't go to sleep you will still be sick because you don't have enough energy and your white blood cells won't have enough energy. So when your sick and you feel tired you need to go to sleep so you can get better. Platelets are what makes your bleeding stop like for example when you scrape your knee on the side walk you will bleed, but for a few minutes your platelets will come and stop the bleeding then your bleeding will stop and then when your bleeding stops the next day you'll have a scab on your knee. Also think if you didn't have enough platelets you will bleed to death if you scraped your knee on the side walk or something else that you can scrape your knee on, which means.  Red Blood Cells are what make your blood red and make your blood have oxygen. 

Arteries

    

                            

How is blood traveling around our bodies? Well our blood travels in tubes that are all around our body. One of the tubes in our body that carries the blood, which is the red blood and that tube is called an Artery. Arteries are the biggest tubes in your body and they carry the rich blood which is the red blood. Another thing arteries can do is that they can pump blood faster then the veins.Your arteries also carry your blood away from the heart and the blood that is taken away from your heart is the blood that has oxygen and that blood is red which is the blood that comes out of you when you scratch your self on a hard rock floor like a road or a side walk. Even your arteries have thicker walls then your capillaries and veins but why does your arteries have thick walls? Well arteries have thick walls because they can't let the blood leak out. That is why your arteries have thick walls. Did you know that the largest artery in your body is called the Aorta and the Aorta is connected to your heart. But are there any other tubes that make are blood travel to every cell in our body?

Skeletal Muscular System

The Respiratory System

The Circulatory System

Air Sacs of The Lungs

 Where is the air that you breathe in going through? Well the air that you breathe in goes to your body but the air that you breathe in goes to a certain part of your body and that part of your body is called the air sacs. Air sacs are these thin walls in your body. Air sacs are like little holes in a sponge and those holes are filled up with air because when you breathe in the air travels really fast and goes to your air sacs into the holes in your air sacs then goes to every cell in your body. They are also covered up with millions and millions of capillaries. Capillaries are not apart of the respiratory system capillaries are apart of the circulatory system. Did you know why air sacs are called air sacs well an air sac is called an air sac because there is air in the holes and they are in a sac covered up in capillaries, but maybe thats why they are called air sacs. But did you know that air sacs are the tiniest tubes in your lungs and air sacs are like these little tiny balloons too. Also the air that you breathe in goes from your lungs so fast to your air sacs and then to your blood, but why does the oxygen air go to the blood? Well your air goes to your blood because your blood needs oxygen so you can live.Even there are names for some of your air sacs and one of the names of your air sac are called  Alveoli's. But is air sacs the only place your air that you breath in can go through?

But is that the only place your air can go through.
