Objective 20:"Look out she's comming through"

Mrs. Guess asked all of the students to step out into the hall and line up into two lines side by side. Her analogy was that she was a red blood cell traveling through the capillaries in our body's. As she was pushing her way through all of us she was bumped around a great deal, which represented how the red blood cells are pushed through the blood and how their outer layers get ripped off. Because red blood cells have no nucleus they are not able to reproduce or repair themselves. That is why they have such a short life span of only 100-120 days. Red blood cells carry the the oxygen and carbon dioxide in the blood. In pictures the look like little doughnuts. There are about 4 to 6 million red blood cells found in the blood

 

There are five different types of leukocytes:

Neutrophils:have multi lobes, and eat up bacteria, about 3000-7000 cells found in body, live anywhere      from 6 hours to a few day. About 3000-7000 are found in our bodies.

Eosinophils:bi-lobed, kill bad worms, help with allergies and asthma, about 100 - 400 cells found in body,live approximately 5 days. 100-400 of these take up space in our blood.

Basophil:is also bi-lobed, these poor guys only live a few hours to maybe a few days, their job is to release histamine and other hormones that help with inflammation. These are only about 20-50 of these guys in our blood.

Neutrophils, Eosinophils, and Basophils are all Granulocytes.

Agranulocyes include Lymphocytes and Monocytes.

Lymphocytes: are spherical shaped, they attack the bad guys cell to cell or by antibodies, they can live for hours or for years. About 1500-3000 can be found circulating through our bodies.

Monocytes: have a U shaped structure they live for only a few months, their job is to eat up the bad guy. There are about 100-700 of these cells found in the body.

Like always under the microscope everything looks the same to me. However in the pictures above each cell type looks different.

Neutrophils look like a bunch of little dots in one big pink circle

Eosinophils look like....... well I don't know what they look like

Basophils look like a purple moon with craters

Lymphocytes look like a solid purple blob

Monocytes look just like the book says U shaped
