Blood is an essential part of your body (no duh, right?) It delivers oxygen and nutrients to the cells of the body and it also transports waste products away from the cells.
It is made up of blood cells suspended in a liquid called blood plasma. Plasma is about 55% of the fluid found in blood and is mostly water. Floating in the plasma are:
- hormones (help to regulate body activities like mood, sleep, growth, etc.)
- glucose, (sugars for energy)
- carbon dioxide (which the body is trying to get rid of.)
- platelets (for clotting if you are cut)
- red blood cells (contain hemoglobin, which helps to move oxygen.)
- white blood cells (help resist infections and deal with parasites.)
Blood is made up of the following four components:
1. Red blood cells. These make up 40-50% of blood by volume. Their function is to carry oxygen from the lungs to all parts of the body.
2. White blood cells. These make up only about 1% of a healthy person's blood by volume. But they are very important in that they help rid the body of harmful organisms like bacteria.
3. Platelets. These are the part of blood that allows it to clot at the site of a wound.
4. Plasma. This is made up mostly of water. It helps bring nutrients to the cells and to carry waste away from them. About 55% of blood (by volume) is plasma.
Blood consists of a watery fluid called plasma containing certain floating bodies termed formed elements. The latter include blood cells or corpuscles and blood platelets or thrombyocytes . The blood corpuscles are of two types : red corpuscles, or erythrocytes (RBCs) and white corpuscles, or leucocytes (WBCs). None of the corpuscles divides in the blood. The plasma and formed elements form about 55% and 45% of the volume of the blood respectively.
Plasma. The plasma is a faint yellow, slightly alkaline, somewhat viscous fluid. It is a complex mixture which is in dynamic equilibrium with the intercellular fluid bathing the cells and the intracellular fluid present within the cells. It constantly takes up and loses materials as it flows through the capillaries, yet it has constant chemical composition. It consists of about 90% water, 1% inorganic salts in true solution, and 7 or 8% proteins in colloidal state. The remaining 1 or 2% of the plasma is formed from food materials, waste products, dissolved gases, regulatory substances, anticoagulant, cholesterol and antibodies. These substances do not form an integral part of the plasma as they enter and leave at intervals. They are carried by the plasma form one place to another in the body.
Proteins. The plasma contains a number of proteins: serum albumen (albumin), serum globulins, properdin, prothrombin and fibrinogen

There are four components of the blood: red blood cells, platelets, white blood cells, and plasma. Red blood cells are responsible for transporting oxygen and getting rid of carbon dioxide. Platelets works with blood clotting at sites of wounds. White blood cells fight of infections. Lastly, plasma brings nourishment to the heart and removes the waste products of metabolism.
Blood consists of red blood cells, platelets, white blood cells and plasma. Platelets clot the blood, white blood cells fend off infections and the last two components of blood carry substances around.

Blood is an essential component of the body. It is the liquid flowing throughout our body carrying out various functions.
Blood is made up of upto 4000 different components. There are 4 major components which are as follows:-
Plasma makes up 55% of our bloods volume. The main function of plasma is t. clean blood from toxins produced by metabolism process. It is yellow in color and carries hormones, proteins and nutrients throughout the boDy. It contains red blooD cells, white blood cells and platelets, that nourishes cells when being pumped from heart. It contains somewhat 500 proteins.
2. Red blood cells
Red blood cells carry oxygen from lungs throughout the body to various organs and tissues and also carry back carbon dioxide. Red blood cells are made continuously in our bonemarrow by stem cells. 95% of the red blooD cells comprises of haemoglobin which are the gas transport protein molecules.
Platelets are produced in the bonemarrow from stem cells. Platelets main function is to stop blood from bleeding when you get a cut in form of clotting. It also invades and kills bacteria while stimulating the immunity system.
4. White blood cells
White blood cells are found very little like 1% in the blood. these are usually made by stem cells and also at various different locations like thymus gland found in the base of the neck. White blood cells main function is directly related to immunity. These seek, recognize viruses, bacteria, Fungi etc that cause diseases and kills them. White blood cells also remove dead blood cells from blood keeping it healthy.
bloos is basically a colloidal solution. its red colour is due the iron complex found in blood.
Due to d-d transitions its red colour appears. To show that blood is a colloidal solution :
when due to some injury blood starts to flow FeCl3 can be applied which is an electrolyte
it coagulates the blood and blood clotting is thus done.
