Blood also may be analyzed on the basis of properties such as
total volume, circulation time, viscosity, clotting time and clotting abnormalities, acidity (pH), levels of oxygen and carbon dioxide
, and the clearance rate of various substances (see kidney function test).

What are physical properties of blood?
Physical Characteristics
Blood is a fluid that is technically considered a connective tissue. It is an extracellular matrix in which blood cells are suspended in plasma. It normally has a
pH of about 7.4
and is slightly denser and more viscous than water.
What are the three properties of blood?
- Amount: : 7-9% of total body weight; 79ml/kg.
- Blood volume: 5-6 liters.
- Viscosity: (3.5-5.5) times more than water.
- Specific Gravity:045-1.065.
- PH:3-7.4 (slightly alkaline)
- Venous blood has low pH than the arterial blood as venous blood has more CO.
- Temperature- 38

What is human blood made of?
Your blood is made up of
liquid and solids
. The liquid part, called plasma, is made of water, salts, and protein. Over half of your blood is plasma. The solid part of your blood contains red blood cells, white blood cells, and platelets.

- Blood Provides the Body’s Cells with Oxygen and Removes Carbon Dioxide. …
- Blood Transports Nutrients and Hormones. …
- Blood Regulates Body Temperature. …

What are properties of blood?

total volume, circulation time, viscosity, clotting time and clotting abnormalities
, acidity (pH), levels of oxygen and carbon dioxide, and the clearance rate of various substances (see kidney function test).
What is the main function for blood in the body?
Blood is needed
to keep us alive
. It brings oxygen and nutrients to all the parts of the body so they can keep working. Blood carries carbon dioxide and other waste materials to the lungs, kidneys, and digestive system to be removed from the body. Blood also fights infections, and carries hormones around the body.
What are the 7 types of blood cells?
Blood cells. Blood contains many types of cells:
white blood cells (monocytes, lymphocytes, neutrophils, eosinophils, basophils, and macrophages), red blood cells (erythrocytes), and platelets
. Blood circulates through the body in the arteries and veins.
What are chemical properties of blood?
Each red blood cell is about one-third hemoglobin, by volume. Plasma is about 92% water, with plasma proteins as the most abundant solutes. The main plasma protein groups are albumins, globulins, and fibrinogens. The primary blood gasses are
oxygen, carbon dioxide, and nitrogen
.
What is the color of the blood?
Human blood is
red
because hemoglobin, which is carried in the blood and functions to transport oxygen, is iron-rich and red in color. Octopuses and horseshoe crabs have blue blood. This is because the protein transporting oxygen in their blood, hemocyanin, is actually blue.
How much blood is in the human body?
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.
Which blood type is most common?
The need for
O+
is high because it is the most frequently occurring blood type (37% of the population). The universal red cell donor has Type O negative blood. The universal plasma donor has Type AB blood.
What percentage of blood is platelets?
Whole blood contains red cells, white cells, and platelets (~
45%
of volume) suspended in blood plasma (~55% of volume).
