Blood cells. (1988)

Pedestrians on the streets of the city.

A student works with a microscope.

Blood flows through the vessels, view under the microscope.

Blood treatment on a centrifuge.

The blood was stratified into two components, 60% plasma, the rest is a red layer, mainly red blood cells.

This is an indicator of hematocrit.

The researcher makes a blood smear.

The smear is fixed and stained.

Under the microscope, red blood cells are nuclear-free disc-shaped corpuscles.

In pathological blood, red blood cells can differ significantly from each other in size and shape.

Sickle-shaped erythrocytes indicate sickle-cell anemia.

The blood of a healthy person contains mature red blood cells.

With blood loss, hematopoiesis and the flow of immature forms of red blood cells from the bone marrow into the blood increases.

These cells are called reticulocytes.

A student under a microscope determines the number of red blood cells in

a unit of blood.

Blood tests in the polyclinic laboratory.

Red blood cells are the most numerous elements of blood.

Equipment for blood tests.

For a detailed acquaintance with the shaped elements of blood, electron microscopy is used.

The thinnest sections of cells are obtained with a glass knife on an ultratome.

The slices are prepared in a special way and placed in an electron microscope.

Climbers in the mountains.

Shepherds and herds of animals grazing in the mountains.

People and animals living constantly in the mountains have increased hemoglobin.

Hemoglobin can exist in the blood and in other organisms.

Spectroscope.

Samples of the spectra of different forms of hemoglobin.

Students work with a hemometer.

In the polyclinic, a photoelectrocolorimeter is used to determine the amount of hemoglobin.

The concept of laced blood.

It absolutely cannot be transfused.

If the erythrocytes of one person are mixed with the plasma of another person, in some combinations, gluing, ablucination is observed.

These combinations are unacceptable, they should not be allowed during blood transfusion.

A cartoon telling about blood groups and their ablucination.

Determination of the blood group.

The patient was transfused blood without determining compatibility.

The patient has a headache, the pressure drops, the work of the heart changes.

These are the symptoms of hemotransfusion shock.

Blood transfusion procedure.

White blood cells are white blood cells.

A student examines white blood cells in a blood smear.

Single leukocytes are visible among the erythrocytes.

They are a thousand times smaller than red blood cells.

Leukocytes are distinguished by size, shape of nuclei, presence of granules in the cytoplasm and their color.

A blood sample of a person with leukemia.

There are a lot of leukocytes in the blood, and immature forms predominate.

The number of white blood cells can be calculated in the same way as red blood cells.

All types of leukocytes are shown.

Cartoon explaining the concept of leukocyte formula.

Lymphocytes under an electron microscope.

Changes in the leukocyte formula with the age of the child.

A cartoon showing the protection of the body by leukocytes.

Immune reactions.

The central organs of immunity are the thymus and bone marrow.

Peripheral organs lymph nodes and spleen.

A cartoon explaining the work of immunity.

A cartoon explaining the work of cellular immunity, typical for tissue transplantation.

A cartoon explaining the work of humoral immunity.

Bone marrow examination in white blood disease.

Biochemical blood tests.

Modern equipment for biochemical analyses.

The movement of blood through the vessels, observation under a microscope.
