learning target

1. Know the blood volume of the human body and have a preliminary understanding of blood transfusion.

2. Master the ABO blood type.

3. Outline the principles of safe blood transfusion and the significance of voluntary blood donation.

4. Be able to understand the functions of blood and related knowledge of blood types based on blood transfusion examples in life.

5. Establish the concept that healthy adult citizens should actively participate in voluntary blood donation.

Preview test:

1. What measures do doctors take to treat patients with massive bleeding?

blood transfusion

2. What should you pay attention to before blood transfusion?

To identify the patient's blood type, the principle should be to transfuse blood of the same type. However, when there is no blood of the same type and the situation is urgent, a small amount of blood of the different type can be slowly transfused.

3. How many blood types are ABO blood types?

Four types: A, B, AB, O type

4. How much voluntary blood donation can be done each time without affecting your health?

200~300ml

Independent Study 1: Blood Volume and Blood Transfusion

1. Approximately how much blood volume does a normal person have in weight?

The blood volume of normal adults is relatively constant, about 7% to 8% of body weight.

2. Does everyone who loses blood need a blood transfusion? Under what circumstances is it needed?

no. If the blood loss exceeds 1200~1500ml at one time, it will be life-threatening and blood transfusion must be carried out in time.

Independent Learning 2: Blood Type

discovery of blood types

In the 17th century, after Harvey discovered blood circulation, humans began to try blood transfusions. In 1667, the French philosopher Denis and the surgeon Emmerez transfused 250 ml of sheep blood to a patient. This was the first blood transfusion recorded in human history. Of course, the result was unsuccessful and the patient died.

In 1829, British doctor Brundle completed the first human-to-human blood transfusion experiment. However, the results of subsequent trials were still disappointing. Most patients died and only a few recovered. What was the reason?

Give your opinion

Material 1: The son wanted to donate blood, but the mother refused, thinking it would damage his vitality and cause anemia.
