Question
Blood smear LM x 1000 their nuclei, which are stained a deep blue or purple. Observe the irregular shapes of the nuclei in many white blood cells 3 You might also see small cell fragments in the blood smear. These fragments are platelets, or thrombocytes, which are essential for blood clotting. MAKING CONNECTIONS During Activities 5.3-5.8, you observed connective tissues with diverse structures and functions. Compare the structure (e.g.cell types, protein fibers, ground substance) and function of the following three types of connective tissues: areolar connective tissue, bone, and blood.

Areolar connective tissue is loosely arranged connective tissue that is widely distibuted in the body.Areolar connective tissues consists of cells,fibres and ground substances.
Diffrent type of cells.
1. Fibrobalsts: The most common cell type is fibrobalsts,they secrete the fibres.
2.Macorophages : They fight against infections in the body.
3.Mast cells : They are responsible for release of histamine in the body.
4.Fat cells : Adipose cells
5.Plasma cells.
The fibres that forms mesh like structures of areolar tissue are as follows.
1. Collagen fibres.
2. Elastic fibres.
3. Reticular fibres.
Areolar tissue also contains the ground substances, which is like fluid matrix, it consists of large molecules called Glycosaminoglycans (glyco protien) which link together to form Proteoglycans.
FUNCTIONS : Main function is binding of organs and providing elasticity,it also helps in the moving of adjacent body parts. It contains white blood cells which through the process of phagocytosis helps the body to fight against the invading pathogens
2. Bones: Basic unit of bone is osteon, which is cylindrical in shape.There are two types of bone tissues, compact bone and spongy bone. Bone is formed of 3 types of cells
a)Osteoblasts: They form the protien mixture known as osteoid.
b)Osteocytes: They help in the formation of bone.
c)Osteoclats: They are multinucleated cells located on the surface of the bone.
Function of Bone: The main function of the bone is protection and providing the framework for the body for eg the cranium protects the brain, the rib cage protects the internal organs of the body.They store nutrients, minerals and lipids making bones a essential part of our body. Bones are responsible for the production of blood cells which occur in the bone marrow.
Blood: Blood is a connective tissue and mainly consists of plasma and formed elements, it has no fibres. It comprises of Red blood cells (Erythrocytes). which contain haemoglobin and is responsible for the red color of blood. The other component of blood is Platelets which are responsible for clotting of blood.The other important component of blood is wWhit blood cells or the leukocytes which are the cells of the immune systems that protect the body from infectious diseases.
White blood cells could be agranulocytes, which could be Lymphocytes or Monocytes.
White blood cells could be granulocytes, which may be Basophil,Neutrophil or Eosinophil.
Functions of Blood:Transport of important gases like oxygen and carbon di oxide
Maintains pH of the body and removes toxins from the body
Regulation of body temperature.
Helps in fighting of infection.
