Plasma constitutes 55% of total blood volume. Composed of 90% water, salts, lipids and hormones, it is especially rich in proteins (including its main protein albumin), immunoglobulins, clotting factors and fibrinogen.
What is the composition of formed elements in blood?
Formed Elements. The formed elements are cells and cell fragments suspended in the plasma. The three classes of formed elements are the erythrocytes (red blood cells), leukocytes (white blood cells), and the thrombocytes (platelets).

Which formed elements of blood are most abundant?
Erythrocytes are the most abundant formed elements in the blood.
What is the percentage of serum in blood?
Serum is plasma without the clotting factors. Red blood cells account for approximately 45% of the whole blood, white blood cells and platelets approximately 1%, and serum or plasma accounts for the remainder, approximately 55% of the volume (Fig.
What percent of your body is blood?
adult will have approximately 1.2-1.5 gallons (or 10 units) of blood in their body. Blood is approximately 10% of an adult's weight.
How do you calculate hemoglobin percentage?
Like the CH, a frequency distribution curve is provided for the concentration and the mean concentration is calculated from the histogram. Calculated hemoglobin: The ADVIA back-calculates a hemoglobin (calculated hemoglobin) from the CHCM (i.e. calculated hemoglobin = (CHCM x MCV x RBC count) ÷ 1000.
What is MCV value?
Introduction. Mean corpuscular volume (MCV) is a laboratory value that measures the average size and volume of a red blood cell. It has utility in helping determine the etiology of anemia — calculation of the value is by multiplying the percent hematocrit by ten divided by the erythrocyte count.
Is blood 90% water?
Over 90% of blood plasma is water, while less than 10% consists of dissolved substances, mostly proteins. Blood plasma also contains electrolytes, vitamins and nutrients such as glucose and amino acids. Over 99% of the solid particles in blood are cells known as red blood cells (erythrocytes) due to their red color.
What percentage of our body is blood?
adult will have approximately 1.2-1.5 gallons (or 10 units) of blood in their body. Blood is approximately 10% of an adult's weight.
What percentage of blood is protein?
The protein concentration in plasma/serum is approximately 60–80 mg/mL of which about 50–60% are albumins and 40% globulins (10–20% immunoglobulin G, IgG) (7, 8). The size distribution of blood components ranges from small molecules and ions (< 1 nm) to about 15 μm for white blood cells.
What percentage of your body is water?
60% In adult men, about 60% of their bodies are water. However, fat tissue does not have as much water as lean tissue. In adult women, fat makes up more of the body than men, so they have about 55% of their bodies made of water.
How is blood formed?
Red blood cells are formed in the red bone marrow of bones. Stem cells in the red bone marrow are called hemocytoblasts. They give rise to all of the formed elements in blood. If a stem cell commits to becoming a cell called a proerythroblast, it will develop into a new red blood cell.
What is normal blood percentage?
The amount of blood in the human body is generally equivalent to 7 percent of body weight.
What percentage of hemoglobin is normal?
Results. The healthy range for hemoglobin is: For men, 13.2 to 16.6 grams per deciliter. For women, 11.6 to 15 grams per deciliter.
What is normal WBC?
The normal number of WBCs in the blood is 4,500 to 11,000 WBCs per microliter (4.5 to 11.0 × 109/L). Normal value ranges may vary slightly among different labs. Some labs use different measurements or may test different specimens.
What is MCHC vs MCH?
MCH quantifies the amount of hemoglobin per red blood cell. The normal values for MCH are 29 ± 2 picograms (pg) per cell. MCHC indicates the amount of hemoglobin per unit volume. In contrast to MCH, MCHC correlates the hemoglobin content with the volume of the cell.
What is percentage of water in blood?
This is the liquid portion of the blood. Plasma is 90 percent water and makes up more than half of total blood volume. Other 10 percent is protein molecules, including enzymes, clotting agents, immune system components, plus other body essentials such as vitamins and hormones.

What percent of your brain is water?
The Human Brain is 80% Water If you have ever considered how much of your brain is water, then the answer to it is 80%. That's right! It is estimated that about three-quarters of our brain is water. As such, even slight dehydration can cause fatigue, headaches, lack of mental clarity, stress and sleep issues.
Which formed element composes less than 1% of whole blood and is involved in defense against disease?
White blood cells, also called leukocytes, are much less common than red blood cells and make up less than 1% of the cells in blood. Their role is also very different from that of red blood cells: they are primarily involved in immune responses, recognizing and neutralizing invaders such as bacteria and viruses.
What are the 7 components of blood?
CBC, which includes:
- White blood cell count (WBC)
- Red blood cell count (RBC)
- Platelet count.
- Hematocrit red blood cell volume (hct)
- Hemoglobin (Hgb) concentration. Hemoglobin is the oxygen-carrying pigment in red blood cells.
- Differential blood count.
What are the 4 main components of blood?
Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in. Red blood cells are responsible for carrying oxygen and carbon dioxide. Platelets are responsible for blood clotting. White blood cells are part of the immune system and function in immune response.
