Answers
Answer:
It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including: transporting oxygen and nutrients to the lungs and tissues. ... bringing waste products to the kidneys and liver, which filter and clean the blood.
Answer:
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.
Types of Blood Cells
We have seen blood consist of cells known as formed elements of blood. These cells have their own functions and roles to play in the body. The blood cells which circulate all around the body are as follows:
Red blood cells (Erythrocytes)
RBCs are the biconcave cells and without nucleus in humans; also known as erythrocytes. RBCs contain the iron-rich protein called haemoglobin; give blood its red colour. RBCs are the most copious blood cell produced in bone marrows. Their main function is to transport oxygen from and to various tissues and organs.
White blood cells (Leucocytes)
Leucocytes are the colourless blood cells. They are colourless because it is devoid of haemoglobin. They are further classified as granulocytes and agranulocytes. WBCs mainly contribute to immunity and defence mechanism.
Platelets (Thrombocytes)
Thrombocytes are specialized blood cells produced from bone marrow.
Platelets come into play when there is bleeding or haemorrhage.
They help in clotting and coagulation of blood. Platelets help in coagulation during a cut or wound
