Blood and blood type PPT, part 2: learning by knowledge points

hemoglobin

Red blood cells contain red hemoglobin, which gives blood its red color.

Hemoglobin is an iron-containing protein that easily combines with oxygen, so red blood cells have the function of transporting oxygen.

anemia

1. Iron deficiency: You should eat more foods rich in iron and protein. Such as: lean meat, fungus, kelp, etc.

2. Malnutrition: Mainly caused by lack of vitamin B12 and folic acid, so oral supplementation is enough.

Routine blood tests

Routine blood tests are often used as an auxiliary means for disease diagnosis. The main items checked include red blood cell count, white blood cell count, platelet count and hemoglobin content.

Doctors can initially determine the patient's condition by interpreting routine blood test data.

red blood cell count

Adult men: (4.0～5.5)×1012/L

Adult women: (3.5～5.0)×1012/L

Reduce: anemia, blood loss;

Increase: Polycythemia, pulmonary heart disease, congenital heart disease, severe dehydration and burns, etc.

White blood cell count

Adult: (5～10.0)x109/L

Reduce: typhoid fever, aplastic anemia, viral and protozoal infections, etc.;

Increase: acute infection, acute hemorrhage, acute poisoning, leukemia, late stage of various malignant tumors.

Blood and blood type PPT, part 3: blood donation

Will donating blood affect your own health?

Clinical practice and scientific research have led to the following conclusion: regular blood donation is more beneficial to health.

Practice has shown that people who insist on donating blood in an appropriate amount for a long time have significantly higher levels of fresh blood cells in their bodies than those who have not donated blood. They are more energetic and healthier.

As a healthy citizen, you should actively participate in voluntary blood donation and dedicate your love to saving the lives of others.
