How do Blood Cells and Viruses work in the Human Body? 


To find the answer to the question I would research and if I wanted to learn it quick I would find a summary of it.


I have researched blood cells and found out that there are 8 types of blood cells and there is pretty much only 1 category of blood cells which is white blood cells but erythrocytes are red blood cells and the only type of red blood cells and like with erythrocytes, platelets, which count as blood cells take on their own category of blood cells which does not have a technical term yet, I have also researched some viruses like pnuemococcus that I will talk about but there might not be much about viruses, and I have researched some stuff about the human body.


WIth the data part and presentation part I was going to talk about viruses in the data part and everything else in the presentation part but I cannot so everything goes in here, basically

I will be talking about expiration, covid 19 then  pneumonoccus for the viruses section. 

Exparation is what happens when something,  usually food is left out for too long, also I kind of did an experiment with this even though I didn't mean to. if you had let's say bunch of grated beatroot all in one bowl and one part expired then all of the beetroot would expire immediately

covid 19  is a contagious virus that can be deadly, it is spread by lung air, spit, as well as touching, especially touching the face, which is why we wear masks, it spreads from host to host and affects older people the most, my guess is that it is either because younger people have better immune systems than older people or that younger people's senses are less developed than older people's senses.


Pneumococcus or as the scientific term would be, streptococcus pneumoniae in plural is called pneumococci and it is a gram-positive, and spherical bacteria and can be alpha-hemolytic or beta-hemolytic, and if u didn't understand that I can explin what it means. Gram-positive bacteria are bacteria i with thick cell walls, spherical means shaped like a sphere, alpha-hemolytic means a greenish discoloration and partial hemolysis of the red blood cells immediately surrounding colonies of some streptococci on blood agar plates and, and beta-hemolytic, sometimes  called complete hemolysis (hemolysis  is the extermination of blood cells nd it is what exterminates the blood cells usually)  is a complete lysis of red cells in the media around and under the colonies: the area appears lightened (yellow) and transparent. Streptococcus pneumoniae are usually found in pairs and do not form spores and are non motile, they are also  facultative and anaerobic members of the genus Streptococcus. I will make sense of some of the words again, spores are a rounded resistant form adopted by a bacterial cell in adverse conditions in microbiology( the biology of germs and bacteria) language, anyways non-motile bacteria are bacteria species that lack the ability and structures that would allow them to propel themselves, under their own power, through their environment. Facultative means "optional" or "discretionary" (antonym obligate), used mainly in biology in phrases such as: ... Facultative anaerobe, an organism that can use oxygen but also has anaerobic methods of energy production. It can survive in either environment, and the final word, which is anaerobic means relating to, involving, or requiring an absence of free oxygen.

After talking about the viruses I wil talk about the human body now.

The human body has many parts but I think I will just talk about what I know primarily keeps us alive and our body parts that give us our senses or improve them, first I will talk about what keeps us alive and I will try to keep it all short. The three things that keep us alive are our brain, heart and lungs and you might be saying our soul keeps us alive too but in my perspective and opinion the soul counts as the heart in this, our minds keep us alive because we need to be constantly thinking and when you are not thinking you have to be talking  but even while you talk you still think and what I'm trying to say is that if we stop thinking we immediately stop living and it might be a bit dark but it is the truth, the way our hearts keep us alive is that they have to keep beating to work and they have to be  working so that our soul stays in our body because our hearts are connected to our soul and if someone's  heart stops working their soul leaves their body and then they would be dead and a common way a person's heart stops beating  is when the person gets a heart attack, and finally the reason our lungs keep us alive is because we must breath to live and we can only hold our breath for 3 minutes (please don't try holding your breath for that long) and the reason we die if we hold our breath for about 3 minutes is because our lungs are overfilled with air and you might ask "why do they not overfill while we are breathing because we are letting more air in when we breath than when we are holding our breath because we let no air in while holding our breath" and I theorize it is because when we breathe we are letting out the air every 2 seconds-ish but when we hold our breath and keep the air boxed in welet the air slowly overfill and destroy our lungs.


Now that I am talking about what make our senses and improve them I will try to get this over with quickly, and I will talk about the 5 senses and something else I think of as an sense. Our sense of sight comes from our eyes and  some people are born blind and my theory to why that is that the things behind our eyes probaby help us see through our eyes, so some people could be born with the things behind their eyes not working so well, also the only way  you could improve your sense of sight would be to give your eyes proper rest or better rest. Your sense of hearing comes from your ears and what improves your sense of hearing are these little hairs in your ears that help you hear better but as you get older they fall out and I think the reason that some people are born deaf is because they are not born with the little hairs in their ears or they do not have much of them when they are a baby and then the hairs would fall out soon.This sense is the sense of smell, which comes from your nose, the only way I would say  you could improve this sense would be to be around more easily smellable objects like food or polluted water. Your sense of touch comes from your nerves and when your nerves are kept in the same position for too long it feels tough to feel stuff physically and you feel numb so the only way you could improve your sense of touch would be to try to keep our hands in the same position for as short as you can. Your sense of taste comes from your tastebuds  which identify the flavour of something and you probably couldn't impove your tastebuds because they could be too good to impove.The last "sense" is the sense of gut feeling and that comes from your gut but I also consider instincts and gut feelings the same and instincts come from the heart and you should trust your gut feling and insincts because gut feelings are always right but instincts are mostly right.


Now I will be talking about Blood Cells and this probably sounds a bit rushed and it could be because I am doing this on the night before it is due.

There are 8 types of blood cells which are called neutrophils, monocytes, lymphocytes, eosinopils, basophils, macrophages, erythrocytes, and platelets, I will talk about what they are individually, what they do, and what they have in common. Neutrophils are a type of white blood cells like every other blood cell expect for platelets and erythrocytes and neutrophils form up to 40% to 70% of the blood cells in the human body, they form an essential part of the immune system. Monocytes are a type of leukocyte, or white blood cell. They are the largest type of leukocyte and can differentiate into macrophages and myeloid lineage dendritic cells. As a part of the vertebrate innate immune system monocytes also influence the process of adaptive immunity. A lymphocyte is a type of white blood cell in the immune system of jawed vertebrates. Lymphocytes include natural killer cells, T cells, and B cells. They are the main type of cell found in lymph, which prompted the name "lymphocyte". Lymphocytes make up between 18% and 42% of circulating leukocytes. Eosinophils are a type of disease-fighting white blood cell. This condition most often indicates a parasitic infection, an allergic reaction or cancer. You can have high levels of eosinophils in your blood (blood eosinophilia) or in tissues at the site of an infection or inflammation (tissue eosinophilia). Basophils are a type of white blood cell. Basophils are the least common type of granulocyte, representing about 0.5% to 1% of circulating white blood cells. However, they are the largest type of granulocyte. Listen to pronunciation. (MA-kroh-fayj) A type of white blood cell that surrounds and kills microorganisms, removes dead cells, and stimulates the action of other immune system cells. Red blood cells, also referred to as red cells, red blood corpuscles, haematids, erythroid cells or erythrocytes, are the most common type of blood cell and the vertebrate's principal means of delivering oxygen to the body tissues—via blood flow through the circulatory system and they also transfer nutrients. Platelets, also called thrombocytes, are tiny fragments of cells that are essential for normal blood clotting. They are formed from very large cells called megakaryocytes in the bone marrow and are released into the blood to circulate and they are what fix wounds which are actually caused by germs. All white bood cells have to exterminate germs from the human body but erythrocytes are red blood cell and then platelets are in thir own category.


In conclusion I have said everything I know, that I could fit in about viruses, blood cells, how they work in the human body, and the human body itself.


My sources were mainly google and I searched up  the definitions and I copy-pasted some of the words and I also came up with some of them just by thinking.


I would like to than my mom for helping me with this when I had a headache, I would also like to thank my big brother for teaching me what citaton means.
