About This Presentation

Description : Check out this medical PowerPoint presentation titled "The Blood System”.

This medical PowerPoint presentation is about the blood system, an essential part of the human body that is responsible for circulating blood throughout the body. Blood is composed of several components, including red blood cells, white blood cells, platelets, and plasma.

Red blood cells contain hemoglobin, which carries oxygen from the lungs to the bodys tissues and organs. White blood cells are part of the immune system and help the body fight infections and diseases. Platelets are responsible for blood clotting, which is essential for preventing excessive bleeding after an injury. Plasma is a fluid that carries nutrients, hormones, and waste products throughout the body.

The blood system also includes several organs, such as the bone marrow, spleen, and liver, which help produce, store, and filter blood. The bone marrow produces new blood cells, while the spleen and liver remove old or damaged blood cells from the body.

Disorders of the blood system can have serious consequences for overall health. Common blood disorders include anemia, leukemia, and hemophilia. Regular check-ups and blood tests can help detect potential problems early, allowing for early treatment and management.

Slide 1-

1 The Blood System The Blood System Arteries Veins
Slide 2-

2 Objectives Objectives After studying this chapter, you will be able to Name the parts of the blood system and discuss the function of each part Define combining forms used in building words that relate to the blood system Identify the meaning of related abbreviations Name the common diagnoses, clinical procedures, and laboratory tests used in treating the blood system
Slide 3-

3 Objectives Part 2 Objectives cont'd List and define the major pathological conditions of the blood system Explain the meaning of surgical terms related to the blood system Recognize common pharmacological agents used in treating the blood system
Slide 4-

4 Structure and Function Structure and Function Blood complex mixture of cells, water, proteins and sugars transports nutrients, oxygen, and hormones to all parts of the body helps regulate body temperature helps maintain stability of the body’s fluid volume transports waste products away from body cells
Slide 5-

5 Blood Composition Structure and Function Without blood, human life is impossible Blood Composition Fluid Portion -Plasma consisting of: water proteins salts nutrients vitamins hormones Cellular Portion -Blood cells consisting of: red blood cells white blood cells platelets NOTE: If some proteins and blood cells were removed from plasma the remaining fluid would be called serum.
Slide 6-

6 Plasma Proteins Structure and Function Plasma Clear liquid made up of 92% water and 8% organic and inorganic biochemicals. Plasma Proteins
Slide 7-

7 Red Blood Cells Structure and Function Red Blood Cells Also known as erythrocytes Produced in the bone marrow in response to erythropoietin Mature red blood cells have no nucleus and appear biconcave Hemoglobin is a protein in red blood cells that is essential to the transport of oxygen Red blood cells live about 120 days
Slide 8-

8 Red Blood Cells Part 2 Hemoglobin Red Blood Cell Count Male = 4.6 to 6.4 Female = 4.2 to 5.4 Average red blood cells in a cubic millimeter of blood Structure and Function Red Blood Cell
Slide 9-

9 Leukocytes Structure and Function Leukocytes Also known as white blood cells Function to destroy foreign substances Two main groups are granulocytes and agranulocytes Granulocytes Agranulocytes Neutrophils Eosinophils Basophils Monocytes Lymphocytes
Slide 10-

10 Platelets Structure and Function Platelets Also known as thrombocytes. Live for about 10 days Assist in blood clotting Red blood cells Platelets Damaged Platelets begin to adhere to tissue edges and to each other as blood escapes. They form a soft platelet plug. Other clotting factors make this a stable plug or clot. Tissue mends and anti-thrombin, and other agents break down the clot.
Slide 11-

11 Blood Types Structure and Function Blood Types Four human blood types or groups exist Individuals needing a blood transfusion must be karyotyped. Blood typing is based on the presence of antigens and antibodies. Blood Types A, B, AB, O People with type O blood can donate to all other types and are called universal donors. Individuals with type AB are called universal recipients.
Slide 12-

12 Rh Factor Individuals receiving incompatible blood during a transfusion will have agglutination or clumping of the blood which can be fatal. Structure and Function Rh Factor In addition to the blood type, there is a positive or negative element found in the blood. Rh positive blood contains an antigen first identified in the rhesus monkeys. Rh negative blood does not contain the antigen. The Rh factor is very important during pregnancy because a mother that is Rh negative carrying a Rh positive fetus will develop antibodies to fight Rh positive blood cells with future pregnancies.
Slide 13-

13 Rh Antibodies Structure and Function Rh negative mom with Rh positive fetus First Pregnancy Antibodies develop Second Pregnancy Another Rh positive fetus If this mother did not receive Rhogam after her first delivery, this baby’s blood cells will be attacked (erythroblastosis fetalis) which could be fatal for the baby.
