important functions in the maintenance of his life.

Слайд 3Blood is composed of plasma and formed elements (cells):
Red blood

cells (erythrocytes)

Platelets (thrombocytes)

White blood cells (leukocytes)

Слайд 4erythrocytes - the most numerous of the formed elements .

Mature red blood cells do not contain nuclei and are

shaped like biconcave disks. Circulating 120 days and destroyed by the liver and spleen. Protein found in red blood cells of iron ions - hemoglobin , which provides the main function of red blood cells - transport of gases in the first place - oxygen. It hemoglobin gives blood red color.

erythrocytes - the most numerous of the formed elements . Mature red blood cells do not contain

Слайд 5Thrombocytes - platelets, non-nuclear blood cells with a diameter of

2 - 4 mm, with irregular rounded shape and are

formed in the red bone marrow from megakaryocytes. Together with plasma proteins ,they provide a blood clotting, arising from damaged blood vessels, leading to stop bleeding, and thus protect the body against life-threatening blood loss.

Thrombocytes - platelets, non-nuclear blood cells with a diameter of 2 - 4 mm, with irregular rounded

Слайд 6Leukocytes - consisting of cytoplasm and nucleus; formed in the

red bone marrow, spleen and lymph nodes. They are involved

in immune responses, choosing T cells that recognize a variety of viruses and harmful substances, B cells that produce antibodies, macrophages that destroy these substances.

Leukocytes - consisting of cytoplasm and nucleus; formed in the red bone marrow, spleen and lymph nodes.

Слайд 7Blood groups
Blood group - a classification of blood for the

presence or absence of certain inherited antigens on the surface

of red blood cells.

Blood groupsBlood group - a classification of blood for the presence or absence of certain inherited antigens

Слайд 8There are four blood types:
no agglutinogens and agglutinins from both

- (0) also known as I;
only agglutinogens A and beta

agglutinins - (A) also known as II;
only B agglutinogens and agglutinins alpha - (B) also known as III;
with both agglutinogens and agglutinins without - (AB) also known as IV.
