Blood cell
A blood cell, also called a haematopoietic cell, hemocyte, or hematocyte, is a cell produced through hematopoiesis and found mainly in the blood. In mammals, these fall into three general categories:
Together, these three kinds of blood cells add up to a total 45% of the blood tissue by volume, with the remaining 55% of the volume composed of plasma, the liquid component of blood. This volume percentage hematocrit is measured by centrifuge or flow cytometry and is 45% of cells to total volume in males and 40% in females.
Haemoglobin (the main component of red blood cells) is an iron-containing protein that facilitates transportation of oxygen from the lungs to tissues and carbon dioxide from tissues to the lungs.
Red blood cells (Erythrocytes)
Red blood cells primarily carry oxygen and collect carbon dioxide through the use of haemoglobin, and have a lifetime of about 120 days. In the process of being formed they go through a unipotent stem cell stage. They have the job alongside the white blood cells of protecting the healthy cells.
Hemocyte (invertebrate immune system cell)
A hemocyte is a cell that plays a role in the immune system of invertebrates. It is found within the hemolymph. Hemocytes are phagocytes of invertebrates.
Hemocytes in Drosophila melanogaster can be divided into two categories: embryonic and larval. Embryonic hemocytes are derived from head mesoderm and enter the hemolymph as circulating cells. Larval hemocytes, on the other hand, are responsible for tissue remodeling during development. Specifically, they are released during the pupa stage in order to prepare the fly for the transition into an adult and the massive associated tissue reorganization that must occur.
There are four basic types of hemocytes found in fruit flies: secretory, plasmatocytes, crystal cells, and lamellocytes. Secretory cells are never released into the hemolymph and instead send out signalling molecules responsible for cell differentiation. Plasmatocytes are the hemocytes responsible for cell ingestion (phagocytosis) and represent about 95% of circulating hemocytes. Crystal cells are only found in the larval stage of Drosophila, and they are involved in melanization, a process by which microbes/pathogens are engulfed in a hardened gel and destroyed via anti-microbial peptides and other proteins involved in the humoral response. They constitute about 5% of circulating hemocytes. Lamellocytes are flat cells that are never found in adult cells, and instead are only present in larval cells for their ability to encapsulate invading pathogens. They specifically act on parasitic wasp eggs that bind to the surfaces of cells, and are incapable of being phagocytosed by host cells.

Mr. Dayton
by: Homicide[Verse 1:]
My name is Dayton, the triple gold killa,
I be the reason for murder to a po black young nigga.
Flow deep on your shit lookin' hella clean.
See, I'm the reason, that niggas look at you mean.
I bring jealousy and hate when I roll through.
Havin' niggas jockin' on your car that you never new.
I make the game worth winnin', gold spokes spinnin',
But don't let me catch your ass slippin'.

So you best invest in more protection.

Cuz when a nigga gets killed, I'm the evidence.
So it's 1-8-7 all day.

Have enough scratch to relax on some gold daytons?

So catch me if you can Mr. D-A,

[Verse 3:]
1 nigga, 2 killas, 3 daytons, 4.
It's murder after dark, when them G's ride low.
Reflections of death, triple gold punk bit the block on them thangs,
Now every bitch know my name.
Ain't no hope, when I step out the station,
Every nigga sprung on them guns and the gold daytons.
All day, every day, it's the same shit,
Every nigga tryin' to find his way up out the game, quick.
Cuz Mr. Cop and Mr. Fed want a nigga dead.
But the park's in my heart, so them fools bled.
I'm hittin' corners, pushin' levels with that deep shit.
These undercovers tryin' to catch me on the weak tip.
I'm from the 4-block, but the OG's, they rock forever
Don't slip on these dark streets cuz the one-time way too clever.
Home invasion, I'll have a nigga soaked in blood.
Niggas can't deal with that Oak Park Terrel love.

Bloodshed every where, motherfuckers dead.

Some don't understand, I'm a G.
