About This Presentation

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

This medical PowerPoint presentation is about blood, a vital fluid that circulates throughout the body of many animals, including humans. It is composed of plasma, which is a liquid component, and various types of cells, including red blood cells, white blood cells, and platelets.

The main function of blood is to transport oxygen, nutrients, and hormones to the bodys tissues and organs and remove waste products such as carbon dioxide. It also plays a crucial role in the immune system by transporting white blood cells and antibodies to fight infections.

The color of blood is typically bright red when it is oxygenated and darker red or blue when it is deoxygenated. The composition of blood can vary depending on a persons health and the presence of any medical conditions. A blood test can provide valuable information about a persons health, including their blood type, cholesterol levels, and blood sugar levels.

Plasma-55% Formed elements-45% Blood Buffy coat-<1%

Buffy Coat- <1% Leukocytes Platelets
Slide 8-

Erythrocytes (red blood cells) Leukocytes (white blood cells) Platelets (thrombocytes) Formed Elements of the Blood-45%
Slide 9-

Erythrocytes
Slide 10-

Erythrocyte7.5m in dia · Anucleate- so can't reproduce; however, repro in red bone marrow · Hematopoiesis- production of RBC · Function- transport respiratory gases · Hemoglobin- quaternary structure, 2  chains and 2  chains · Lack mitochondria. Why? · 1 RBC contains 280 million hemoglobin molecules · Men- 5 million cells/mm3 · Women- 4.5 million cells/mm3 · Life span 100-120 days and then destroyed in spleen (RBC graveyard)
Slide 11-

Hemoglobin
Slide 12-

Blood Cell Production
Slide 13-

Anemia- when blood has low O2 carrying capacity; insufficient RBC or iron deficiency. Factors that can cause anemia- Exercise- causes need for more hemoglobin and also sweat includes iron B12 deficiency RBC Diseases
Slide 14-

Sickle-cell anemia- Found in 1 out of 400 African Americans. Homozygous for sickle-cell is deadly, but in malaria infested countries, the heterozygous condition is beneficial. RBC Diseases
Slide 15-

Polycythemia- excess of erythrocytes,  viscosity of blood; 8-11 million cells/mm3 Usually caused by cancer; however, naturally occurs at high elevations Blood doping- in athletesremove blood 2 days before event and then replace it- banned by Olympics. RBC Diseases
Slide 16-

Granulocytes Neutrophils- 40-70% Eosinophils- 1-4% Basophils- <1% Agranulocytes Monocytes- 4-8% Lymphocytes- 20-45% Never let monkeys eat bananas 4,000-11,000 cells/mm 3 Types of Leukocytes

ID WBC’s
Slide 19-

Leukopenia Abnormally low WBC count—drug induced Leukemias Cancerous conditions involving WBCs Named according to the abnormal WBC clone involved Mononucleosis highly contagious viral disease caused by Epstein-Barr virus; excessive # of agranulocytes; fatigue, sore throat, recover in a few weeks WBC Diseases

Hemostasis- stoppage of bleeding Tissue Damage Platelets: 250,000-500,000 cells/mm3
Slide 22-

Hemostasis: 4. Coagulation Vessel injury 2. Vascular spasm 3. Platelet plug formation
Slide 23-

Hemostasis(+ feedback) Traps RBC & platelets Platelets release thromboplastin
Slide 24-

Blood Clot Fibrin thread Platelet RBC
Slide 25-

Disorders of Hemostasis Thromboembolytic disorders: undesirable clot formation Bleeding disorders: abnormalities that prevent normal clot formation
Slide 26-

Thromboembolytic Conditions Thrombus: clot that develops and persists in an unbroken blood vessel May block circulation, leading to tissue death Embolus: a thrombus freely floating in the blood stream Pulmonary emboli impair the ability of the body to obtain oxygen Cerebral emboli can cause strokes
Slide 27-

Thromboembolytic Conditions Prevented by Aspirin Antiprostaglandin that inhibits thromboxane A2 Heparin Anticoagulant used clinically for pre- and postoperative cardiac care
Slide 28-

Thrombocytosis- too many platelets due to inflammation, infection or cancer Thrombocytopenia- too few platelets causes spontaneous bleeding due to suppression or destruction of bone marrow (e.g., malignancy, radiation) Platelet count <50,000/mm3 is diagnostic Treated with transfusion of concentrated platelets Bleeding Disorders
Slide 29-

Impaired liver function Inability to synthesize procoagulants Causes include vitamin K deficiency, hepatitis, and cirrhosis Liver disease can also prevent the liver from producing bile, impairing fat and vitamin K absorption Bleeding Disorders
Slide 30-

Hemophilias include several similar hereditary bleeding disorders Symptoms include prolonged bleeding, especially into joint cavities Treated with plasma transfusions and injection of missing factors Bleeding Disorders
Slide 31-

Hemophiliac- a sex-linked recessive trait, primarily carried by males (x chromosome)
Slide 32-

Type A Type B Type AB Type O Blood Types
Slide 33-

Blood type is based on the presence of 2 major antigens in RBC membranes-- A and B Blood type Antigen Antibody A A anti-B B B anti-A A & B AB no anti body Neither A or B O anti-A and anti-B Antigen- protein on the surface of a RBC membrane Antibody- proteins made by lymphocytes in plasma which are made in response to the presence of antigens. They attack foreign antigens, which result in clumping (agglutination) Blood Typing

Type AB- universal recipients Type O- universal donor Rh factor: Rh+ 85% dominant in pop Rh- 15% recessive Blood Type Clumping Antibody A antigen A anti-A serum antibody anti-b B antigen B anti-B serum antibody anti-a AB antigen A & B anti A & B serum - O neither A or B no clumping w/ either anti A or B anti-a, anti-b
