BLOOD :
HOW MUCH DO YOU KNOW ABOUT YOUR BLOOD?!
Basically, anyone would say blood is a red-coloured fluid that gushes out of your body when you have a cut or bleed on any part of your body. It is known to be a key player in the circulatory system.
But on a standard and more complex note,
Blood is a fluid found in the body of vertebrates and other invertebrates circulatory system that is pumped by the heart and circulated throughout the body cells, tissues and systems by passing through veins, arteries and capillaries carrying oxygen and nutrients to body cells, removing carbon(iv)oxide and waste products from body cells and tissues and then transporting hormones and other substances needed by the body for functions such as metabolism, growth, and protection of body from foreign particles (such as pathogens).
And I must say, that’s a lot of grammar!
Now, back to knowing more about blood,
HEMATOLOGY is the branch of medicine that deals with the study of (anything about) blood.
• The white blood cells, WBC or Leukocytes
• The platelets or Thrombocytes
all contained in a yellow liquid called
• Blood plasma
¬¬_**When blood is centrifuged, the tube shows,
• A yellow liquid (blood plasma) at the top which is about 55% of the entire volume and contains water, nutrients, proteins, hormones and the likes.
• A thin with layer with buffy coat
And,
• A red liquid (RBC) at the bottom of the tube.
All the various cells of blood are made in the bone marrow in a process called HEMATOPOESIS.
** The formation of Erythrocytes is known as ERYTHROPOESIS while that of Leukocytes and Thrombocyte is known as MYELOPOESIS.**
During childhood, almost every human bone produces red blood cells. But in Adults, RBC production is limited to larger bones.
The proteinaceous components of blood are produced predominantly by endocrine glands and the watery fraction is regulated by the hypothalamus and maintained by the kidney.
The pigment found in blood is known as HEMOCHROME and is largely due to the protein in the blood responsible for oxygen transport. These proteins differ depending on the organism involved.
The colours described after the pigments refer to the colours of the pigment when oxygenated and deoxygenated.
• Hemoglobin in vertebrates
Bright red to Dark red
• Hemocyanin in most molluscs such as crabs
Dark blue to Colourless
• Chlorocruorin in most annelids (round worms)
Violet-pink to Colourless
• **Hemerythrin **
¬¬¬Green to Red¬

I’m pretty sure this heading would leave you wondering, is there a care for one’s blood?
The garbage in and garbage out function carried out by the blood when it circulate oxygen and nutrients, battle with pathogens and remove waste products from various body cells determines the health condition of the organism concerned.
Since the blood functions day and night year-round, keeping its nature at standard should be of high priority.
This helps to reduce blood pressure, glucose level, heart disease risk and prevent the accumulation of waste and iron overload in the body system.
Stem cell transplantation
Stem cells are cells that form the blood cells. Their transplant would cause formation of new and healthy stem cells in the body.
Using chemotherapy and radiation therapy for blood cancers and disorders.
