Answer:
Explanation:
Composition of Blood
Composition of Blood: Plasma, RBCs, WBCs and platelets
Components Of Blood
There are many cellular structures in the composition of blood. When a sample of blood is spun in a centrifuge machine, they separate into the following constituents: Plasma, buffy coat and erythrocytes.
Composition of Blood
Plasma
The liquid state of blood can be contributed to plasma as it makes up ~55% of blood. It is pale yellow in colour and when separated, it consists of salts, nutrients, water and enzymes. Blood plasma also contains important proteins and other components necessary for overall health. Hence, blood plasma transfusions are given to patients with liver failure and life-threatening injuries.
Red Blood Cells (RBC)
Red blood cells consist of Haemoglobin, a protein. They are produced by the bone marrow to primarily carry oxygen to the body and carbon dioxide away from it.
White Blood Cells (WBC)
White blood cells are responsible for fighting foreign pathogens (such as bacteria, viruses, fungi) that enter our body. They circulate throughout our body and originate from the bone marrow.
Platelets
Tiny disc-shaped cells that help regulate blood flow when any part of the body is damaged, thereby aiding in fast recovery through clotting of blood.
The above-stated elements form the composition of blood in humans. The only vertebrate without haemoglobin is the crocodile icefish. It derives its oxygen requirement directly from the cold, oxygen-rich water where it lives.
Explanation:
components of blood are
•red blood cells
•white blood cell
•platelets
1. red blood cells also called rbc . its main function is to produce blood
2. white blood cell also called WBC .they are fighting mechanisms of our body.they fight with other particle entering our body by building antibodies against them
3. platelets they repair the infected tissue or cell
