The document discusses the constituents of human blood. Blood consists of plasma and blood cells. Plasma is made up of water, proteins, nutrients, and waste products. It transports these substances between tissues. Blood also contains red blood cells, white blood cells, and platelets. Red blood cells carry oxygen and carbon dioxide. White blood cells help fight infection. Platelets aid in blood clotting. The document also covers blood typing and transfusion compatibility, as well as the importance of blood donations.

Blood is a liquid connective tissue that contains cellular elements (blood cells) and fluid matrix (plasma).
Blood helps in the transportation of different substances throughout the body.
Study of blood and its disease is known as Hematology.
The cellular components of blood are erythrocytes (red blood cells, or RBCs), leukocytes (white blood cells, or WBCs), and thrombocytes (platelets). By volume, the RBCs constitute about 45% of whole blood, the plasma about 54.3%, and white blood cells about 0.7%. Platelets make up less than 1%.

Blood is a vital fluid connective tissue in the body.
It delivers oxygen and nutrients to the organs and tissues while removing waste products.
Study of blood is called HAEMATOLOGY.
Blood makes up about 7% of the total body weight of an adult, with an average volume of about 5 liters in males and 4.5 liters in females.
Blood is constantly replenished through a process called Haematopoiesis, which occurs in the bone marrow.

Blood
It is a connective tissue and circulating fluid including plasma and blood cells.
Physical characteristics:
More viscous than water.
100.4 degree F temperature.
8% of total body weight.
Average blood volume in males is 5-6 liters and female 4-5 liters
Composition of blood
Blood is made up of two main components.
Plasma (55%)
Blood cells (45%)
Plasma:
Normally 55% of our blood is made up of plasma
Composed of approximately 90% water.
plasma is the liquid portion of the blood.
Composition of blood
Plasma can be divided into 6 components:
Inorganic ions or Mineral ion.
The plasma proteins
Organic nutrients
Nitrogenous waste products
Hormones
Gases
Composition of blood
Blood cells 3 types of blood cells are
Red blood cells (erythrocytes)
White blood cells (leucocytes)
Platelets (thrombocytes)
Red blood cells:
Also called erythrocytes & Biconcave shape
95% of the RBC consist of haemoglobin(red pigment)
Remaining 5% consist of enzymes, salts and other protein
Formed in red bone marrow
Average life span is 4 months (120 days)
Composition of blood
Function:
To transport oxygen & carbon dioxide.
Blood of male contains 5-5.5 million RBC per cubic millimetres.
Blood of female contains 4-4.5 million RBC per cubic millimetres
2) White blood cells: Also called as leucocytes
They are colourless & Much larger than red blood cells
One cubic millimetres of blood contains 7000 to 8000 WBC
Formed in bone marrow
Their life span depends on the body need so they have life span of months or even years
Composition of blood:
Types of WBC:
Granulocytes: neutrophils, eosinophils and basophils.
Agranulocytes: monocytes and lymphocytes.
Main function:
These are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders.
Composition of blood:
3) platelets: also called Thrombocytes.
Normal platelet count is 150,000-400,000/ drop of blood
Platelets have a life span of only 5 to 9 days
Platelets are formed in Bone marrow
Function:
Involving in blood coagulation (blood clotting)
Blood Formation
Hemopoiesis ( haematopoiesis) or hemopoiesis, is the process that produces the formed elements of the blood.
Hemopoiesis takes place in the bone marrow found in the epiphyses of long bones (for example, the humerus and femur), flat bones (ribs and cranial bones), vertebrae, and the pelvis.
Within the bone marrow, hemopoietic stem cells ( hemocytoblasts) divide to produce various “blast” cells.
Each of these cells matures and becomes a particular blood cells.
The rate of blood cell formation depending on the individual
But - average 200 billion RBC per day, 10 billion WBC per day, and 400 billion platelets per day
Blood Formation
Blood cells are made in the bone marrow & located inside some bones.
It contains young p
The Earth pulls all objects to its centre. This pull is called the force of gravity or gravitational force.
The weight of an object is the pull of the Earth on the object.
Only green plants possess the amazing ability of trapping solar energy to produce food.
Photosynthesis is the process in which green plants absorb solar energy to make food from carbon dioxide and water.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.

Lesson 3.2 Human blood
1.
2. The Constituents of Blood
•The average human has 4 – 6 dm³ of blood
circulating in his body.
•The major constituents of blood can be separated by
centrifugation.
The composition of human blood after centrifuge
3. •Blood consist of fluid called plasma which is made up
of suspended blood cells and blood fragments.
•Plasma makes up 55% of blood by volume. The other
45% consists of red blood cells, white blood cells and
platelets.

4. Plasma
•Plasma is the yellow liquid in our blood.
•90% of plasma is water. The rest are dissolved
substances which include:
•a. Nutrients such as glucose, amino acids and vitamins.
•Proteins like antibodies, hormones, enzymes, albumins,
fibrinogens.
•Inorganic ions such as sodium, calcium, chlorides and
phosphates.
6. Main Functions of Plasma
a. To transport nutrients to tissues.
b. To remove waste products from tissues
c. To distribute hormones, enzymes, antibodies and
other proteins
d. To distribute heat energy from the liver and
muscles to all other parts of the body.
7. Red Blood Cells (Erythrocytes)
•They are biconcave, disc – shaped cells without
nucleus.
•The red blood cells transport oxygen from the lungs to
all parts of the body.
•They contain a red pigment called haemoglobin which
combines with oxygen molecules to form
oxyhaemoglobin.
8. •They also carry carbon dioxide from body cells to our
lungs.
•There are about 5, 000,000 red blood cells in each
cubic millimeter of blood.
•Red blood cells are made in the bone marrow.
•The lifespan of red blood cells is about 120 days.
•When the red blood cells are worn out, they are
destroyed in the liver and spleen.
9. White Blood Cells (Leucocytes)
•White blood cells are much larger than red blood cells
and they have a nucleus.
•They are usually irregular in shape, colourless and do
not contain haemoglobin .
10. •There are several types of white blood cells.
•White blood cells are formed from bone marrow
cells.
•The lifespan of white blood cells depends on the type
of white blood cells. It varies from a few hours to a
few months.
•They play a vital role in the body’s defense against
diseases. Some white blood cells produce antibodies to
render bacteria inactive while other white blood cells
ingest bacteria.
•Unlike red blood cells. White blood cells can squeeze
through the walls of the blood capillaries into the
spaces among the cells to destroy the bacteria.
11. Platelets (Thrombocytes)
•Platelets are cell fragments produced by large cells in the
bone narrow.
•They appear as tiny oval – shaped structures without
nucleus under a high – powered microscope.
•There are between 250, 000 and 500, 000 platelets in
every cubic millimeter of blood.
•They play an important role in blood clotting. When a
blood vessel breaks, the platelets release clotting factors.
12. Blood Groups
•There are many different systems by which blood is
grouped but the ABO system is the best known.
•The ABO system classifies the human blood into main
four groups called A, B, AB, and O.
•During a blood transfusion, the donor’s blood must be
compatible with the recipient’s blood.
•When an incomplete type of blood is transfused, the
red blood cells of the donated blood will clump
together (agglutinate) and cause fatal blockages in the
recipient’s blood vessels.
13. O A B AB

14. •Blood group O can safely donate blood to anyone in
small quantities. People with group O are called
universal donors.
•Blood group AB can safely receive blood from anyone.
Group AB people are called universal recipients.

Blood transfusion – donors and recipients
15. The importance of blood donations
•By donating blood, one could have save lives of
others.
•Blood maybe needed for treatment of accident cases,
cancer victims, haemophiliacs, surgery,
gastrointestinal bleeding and in childbirth where a
great loss of blood occurs.
•The donated blood can be used either as unfiltered
blood for one patient, or separated into components to
help several patients.
16. Main uses of the components of donated blood
Component Main uses
Plasma Great loss of blood in surgery and
childbirth
Red blood cells Anemia
Platelets Bone marrow failure, leukemia
Blood proteins Burns
17. Storage and handling of donated blood
•A donor normally gives about 400 cm³ of blood from
vein in his arm.
•Blood should be collected under aseptic conditions into
a sterilised container containing anticoagulant solution
which prevents clotting.
•The donated blood is tested for ABO group and the
presence of antibodies that maybe cause problems in a
recipients.
•Screening tests are performed for evidence of donor
infection and hepatitis, AIDS and other sexual
transmitted disease.
18. •The date of expiration should be written on the label
attached to the blood container.
•The blood can be stored at 5°C for 10 days, or longer
if glucose is added.
•The blood maybe separated into several components.
•Red blood cells can be stored under refrigeration for
42 days, or they can be frozen for up to 10 years.
•Platelets can be stored at room temperature for a
maximum of 5 days.
•Frozen plasma can be kept for up to 1 year.
•Frozen plasma and red blood cells should be thawed
in a water bath at temperature not exceeding 38°C.
