Biology
1 answer:
Lunna [17]2 years ago
5 0

Answer:

Histocompatibility antigens are encoded on more than 40 loci, but the loci responsible for the most vigorous allograft rejection reactions are on the major histocompatibility complex (MHC).

Explanation:

Transplantation involves transferring from one site to another of cells, tissues or organs, often among people. An organ transplant (eg, kidney, liver, cardiac, lung, or pancreas) from a donor may rectify organ malfunction.

The immune system remains as a standard medical treatment the greatest barrier to transplantation. An effective and intricate mechanism has been evolved in the immune system to fight off invading invaders. These systems also contribute to the refusal of the transplanted bodies that are recognized by the immune system of the receiver as foreign.

which component of blood consists of cell fragments and is the main contributor to healing cuts? A. erythrocytes B. thrombocytes
il63 [147K]

Answer:

The correct answer would be B. thrombocytes.

Thrombocytes, also called platelets are the components of the blood which play important role in the process of hemostasis.

Hemostasis is the process of preventing the flow of blood from the damaged site or damaged blood vessel. It is the first stage involved in the healing of the wound.

Platelets form the platelet-plug at the site of damage which in turn activates another blood clotting factor fibrinogen.

Fibrinogen gets converted into an active fibrin (insoluble) which forms the meshwork like structure to trap more and more platelets and red blood cells. It results in the formation of a clot which completely seals the cut or damaged site.
