In humans, oxygen-rich blood (from the lungs) must not mix with oxygen-poor blood (from other cells). We have 4-chambered heart to ensure there is no mixing.
However, some animals (such as alligators) have no problem letting their blood mix.
The two most common blood types in the US are O positive and A positive.
The two types of blood that are in the heart are oxygen-rich blood that is pumped from the lungs to the body (systemic circulation) and oxygen-poor blood that is pumped from the body to the lungs (pulmonary circulation).
When two incompatible blood cells mix and come into contact with each other, a reaction called agglutination occurs. This can lead to clumping of the blood cells, which can block blood vessels and cause serious health complications.
type "O" which really is zero, means that no antigens are present, it is the universal donor. anyone can take it in without difficulty. there are no antigens which would cause clotting or problems. type "AB" means that you already have both antigens, so you are the universal acceptor. any blood given to you, type A or B, won't hurt you since you already have those antigens. Type "O" has none, so that's good too. the Rh factors will further complicate things, but the ABO blood typing system is that simple. If you are a vampire, other probems might arise.
Two types of blood vessels are arteries, which carry blood away from the heart, and veins, which carry blood towards the heart. There is also a third type of vessel called a capillary which is neither artery nor vein but connects the two and is the site where oxygen, nutrients, and wastes are exchanged between the blood and the tissues.
Not recommended.
No, two A positive parents cannot have a child with O negative blood type. The A blood type parents can pass on either A or O alleles, but since they both have at least one A allele, any offspring would inherit A or AB blood types. The O negative blood type requires two O alleles, which is not possible with parents who both have A blood types.
No, two O positive parents cannot have an AB positive baby. Inheritance of blood type follows specific patterns, and a child cannot have a blood type that is not possible based on the parents' blood types.
There are two types of blood. Deoxygenated blood, and oxygenated blood.
it is rh negative and rh positive that u dont want to mix not the a b o types it is the + or - two ++ mom n dad or two -- mom n dad not 1 positive(+) and 1 negative(-)
You cannot mix only two items.

No, there is no limitation on people of different blood types reproducing.
There are two different types of A blood types, there is the one that originated from Europe and one that originated from the Arctic. The two blood types have specific properties and each require certain foods to be healthy.
