For arterial blood pH=7.41, Venous blood =7.36
Blood is composed of four major components : plasma, red blood cells, white blood cells and platelets
Plasma is about 90% water and also contains vitamins, minerals, nutrients and waste products. Its makes up about 55% of the blood
Red blood cells make up about 45% and contain protein haemoglobin which give blood its red color and allows it to carry oxygen
White blood cells makes up about 1% of blood volume. The three types include the monocytes,lymphocytes and granulocytes

The normal pH of human arterial blood is approximately 7.40 (normal range is 7.35-7.45), a weak alkaline solution. Blood that has a pH below 7.35 is acidic, while blood pH above 7.45 is alkaline. Blood pH along with arterial carbon dioxide tension (PaCO2) and HCO3 readings are helpful in determining the acid-base balance of the body. The respiratory system and urinary system normally control the acid-base balance of blood as part of homeostasis.
Blood is a highly specialized circulating tissue consisting of several types of cells suspended in a fluid medium known as plasma. The cellular constituents are: red blood cells, which carry respiratory gases and give it its red color, white blood cells (leukocytes), which fight disease, and platelets, cell fragments which play an important part in the clotting of the blood.

pH of blood is very close to 7 and that is because of the buffer system in the blood. A buffer system consist of a weak acid and a weak base. Whenever pH of the blood increases and blood becomes acidic, the buffer system produces more base to bring it back to 7 and whenever it becomes more basic, buffer system produces more acid.
Blood consist of Red and White Blood cells, Platelets and Serum (water and different proteins).

The body maintains a pH level of 7.35-7.45 (slightly alkaline).
Blood is composed of 4 main components:
Erythrocytes (red blood cells)
Leukocytes (white blood cells)
Platelets (responsible for clotting)
Plasma (liquid - mostly water)
Each of these components can be broken down further. For example, there are several types of leukocytes, and we could discuss the different proteins that may be present in the plasma, but in simple terms, that's it.

In addition to the answers here, I'd like to add that exercise lowers this value significantly if waste products (e.g. Hydrogen Ions and Lactic acid) can't be removed as quickly as they're being made.

pH (potenial hydrogen) of blood is from 7.35 to 7.45
blood consists of plasma(water), proteins, leukocytes(white blood cells), red blood cells and many other things

don,t think blood has a PH level..and its made up of red cells and i cannot remember anything else as i fell asleep in human biology

It should be 7. It's made of cells and water- basically.

physiological pH is around 7.0.
