Question

Define d following terms -:
phagocytosis
diapedesis
defibrinated blood
blood transfusion

Answer 1

Phagocytes are cells that protect the body by ingesting harmful foreign particles, bacteria, and dead or dying cells. 

Diapedesis, is the movement of leukocytes out of the circulatory system and towards the site of tissue damage or infection. 

Defibrinated sheep blood is perishable and is collected and processed upon receipt of your order.

Blood transfusion is generally the process of receiving blood or blood products into one's circulation intravenously.

Answer 2

hello!
here is the answer for your question

a) Phagocytosis :- Phagocytosis: The process by which a cell engulfs particles such as bacteria, other microorganisms, aged red blood cells, foreign matter, etc. The principalphagocytes include the neutrophils and monocytes (types of white blood cells)

b)diapedesis :- The movement or passage of blood cells, especially white blood cells, through intact capillary walls into surrounding body tissue.

c)defibrination blood :- blood is collected in a sterile bottle containing small glass beads and with constant manual agitation during the bleeding process. For citrated blood, blood was collected in a standard tubes for human blood sampling but in exactly the right ratio of blood and anticoagulants (1,4 ml citrate : 10ml of the blood). In both cases, blood is liquid and can be used to make microbiological media (blood agar).

d)Blood transfusion: The transfer of blood or blood components from one person (the donor) into the bloodstream of another person (the recipient). Blood transfusionmay be done as a lifesaving maneuver to replace blood cells or blood products lost through bleeding or due to depression of the bone marrow. Transfusion of one's own blood (autologous) is the safest method but requires advanced planning, and not all patients are eligible for it. Directed donor blood allows the patient to receive blood from known donors. Volunteer donor blood is usually most readily available and, when properly tested, has a low risk of side effects.
