Blood type compatibility

The presentation reflects material for a biology lesson in grade 8 in accordance with the textbook by N. I. Sonina and M. R. Sapin Biology. Man. The slides present facts from the history of blood transfusion, differences in blood of different groups, compatibility of blood during transfusion.

What types of immunity are known? D / c No. 116: Describe the main mechanisms of protection against infection What do you know about AIDS? Recovery of knowledge

The first experiments on the transfusion of animal blood to man – in the 17th century. The first successful blood transfusion (from lamb to man) took place in 1667. The first blood transfusion from person to person was made by the English doctor J. Blundell in 1819, in Russia – in 1832, blood was transferred from the person by G. Wolf. blood loss woman. Blood transfusion

Blood type compatibility

The explanation of the characteristics of blood transfusion became possible after the creation of the theory of immunity (I. I. Mechnikov, P. Erlich; Nobel Prize in 1908) and the discovery of blood groups (Austrian scientist K. Landsteiner, Nobel Prize in 1930). Karl’s blood transfusion Landsteiner, 1868-1943

PARTICIPANTS OF TRANSFER DONOR – a person who gives blood RECIPIENT – a person who takes blood

The blood of different people varies in composition. In the red blood cells, there may be some antigens (agglutinogens), which were called A and B. In the blood plasma there may be some antibodies (agglutinins) called α and β. Blood types

The blood of different people varies in composition. If during the transfusion of the patient’s and the donor’s blood group, the patient’s blood flow is not correct, then when blood is mixed, agglutination occurs

Blood group I (0) in erythrocytes there are no proteins A and B in the plasma there are antibodies α and β (for proteins A and B) People with the first blood group are universal donors, their blood can be transferred to a person with any blood group Blood groups No. 120

Blood Transfusion Scheme I (0) I (0) II (A) IV (AB) III (B) II (A) III (B) IV (AB)

Blood group II (A) in erythrocytes there is protein A in plasma there are antibodies β (to protein B) People with the second blood group can be transfused with blood or the same group or group I (0) Blood groups

Blood Transfusion Scheme I (0) I (0) II (A) IV (AB) III (B) II (A) III (B) IV (AB)

Blood group III (B) in erythrocytes there is protein B in plasma there are antibodies α (to protein A) People with the third blood group can be transfused with blood or the same group or group I (0) Blood groups

Blood group IV (AB) in erythrocytes is proteins A and B. There is no α and β antibodies in plasma. People with the fourth blood group are universal recipients, they can be transfused with blood of any group. Blood types

Donated blood is used in complex operations, injuries, burns. The blood of one donor is divided into components and, thanks to this, 4-5 patients can save lives.

Rh factor – another blood protein (antigen, agglutinogen). It was first found in the blood of rhesus monkeys in 1940. 85% of people in the blood have this protein, they are called Rh-positive (Rh +) 25% of people do not have this protein in the blood, they are called Rh-negative (Rh -) Rh factor

By topic: methodical developments, presentations and notes

The lesson presentation is held in the course of biology of the 8th class.

Biology lesson topic “Tissue compatibility and blood transfusion” Grade 8 Lesson purpose: To form the concept of human blood groups and the reasons for group differences; rhesus factor; reveal value

The presentation tells about the history of blood transfusion, the problems that arose when trying to transfuse, the causes of these problems. The concepts of donor, recipient are given. It is a question of the meaning of donation.

methodical development contains the topic, purpose, objectives of the lesson, the application in the form of a presentation. The lesson type is combined, the learning method is problematic. Methodical development is made to the lesson according to

The purpose of the lesson: to form students’ knowledge of blood types, to identify the main differences between different blood groups of people, to reveal the concept of red blood cell agglutination, the mechanism of blood transfusion, Rh factor, dono.

The material allows you to gain knowledge about blood groups, the value of the application of transfusion. It contributes to the achievement of metasubject results: to compare, generalize, develop mental abilities. On.

The presentation reinforces the knowledge of deaf students about the composition and functions of blood, introduces concepts of blood loss, blood transfusion, blood types, blood donors .. Speech material studied by n.
