Blood is a heterogeneous mixture because the blood cells are physically separate from the blood plasma. The cells have different properties than the plasma. The cells can be separated from the plasma by centrifuging, which is a physical change.
==========
If it were homogenous, we'd be dead. Human blood is heterogeneous: it's composed of:
- red blood cells, which carry oxygen,
- white blood cells, which fight infection,
- liquid plasma, which carries proteins and minerals in suspension,
- platelets, which produce clotting when a blood vessel is ruptured or cut.
Human blood is decidedly NOT homogeneous. It is composed of many different components, each with it's own important function: The main components of blood are the plasma (the liquid that everything else floats in), red blood cells (transporting oxygen to and carbon dioxide from cells), white blood cells (fighting infection), and platelets (clotting, repair of injuries). There are many other things that may be found in blood including nutrients, waste products (other than carbon dioxide), antibodies, and hormones. At any given time most of the blood in an individual will have very similar composition other than the obvious differences between arterial blood (going to the cells) and venous blood (coming back from the cells) and differences between blood entering organs like the kidneys and liver and the blood leaving those organs.
Blood is heterogeneous because your blood has many other substances included like plasma, RBC, WBC, haemoglobin, etc and all these substances can be separated through a simple physical method like Plasma Pheresis !!
Thus blood is a Heterogeneous substance as we can also see its different parts maybe under a microscope !! :D and also O2 and CO2 are no uniformly distributed in blood making it heterogeneous !! Hence proved :P
What else can I help you with?
Why is sand homogeneous?
Sand is not a homogeneous material.
Is salt homogeneous our hetergeneous?
Pure salt is a homogeneous material.
Suspended and dissolved material indicates what?
The meaning of "dissolved" is that a material (solute) form a homogeneous solution.Suspended material float in a liquid but is not soluble; it is a non-homogeneous mixture.
Is Au and Hg homogeneous or heterogeneous?
Gold-mercury amalgam is a homogeneous material.
Blood is a homogeneous compound?
Blood is not a compound; it is a mixture composed of different components such as red blood cells, white blood cells, platelets, and plasma. These components are not chemically bonded together, making blood a heterogeneous mixture, not a compound.
Can a non homogeneous material be isotropic?
NO
Is barium a homogeneous or heterogeneous mixture?
Barium is an element and therefore a pure substance, so it is considered a homogeneous material.
Is vegetable oil a homogeneous or a heterogeneous?
Filtered an nonaltered vegetable oil is a homogeneous material.
What classifies a material as a solution?
It is a homogeneous mixture.
