sangre

• la sangre es un tejido ___


  conectivo
• (parte líquida) es viscoso, compone el 55% de sangre

  plasma
• célula roja = eritrocito
• las células sanguíneas son las encargadas del transporte de oxígeno y nutrientes por todo el cuerpo.
• células blancas = leucocitos
• células plateletes = trombocitos
• como la anatomía de la célula sanguina roja permite que cargue oxígeno y dióxido carbono ?


  el pigmento en la célula eritrocitos llamado hemoglobin permite eritrocitos y oxigeno se combinen en los pulmones para transportarlo a tejidos del cuerpo despues para combinar con el dióxido carbono en los tejidos y transporta a los pulmones como desecheo
• of the three proteins in plasma — is the one that plays a role in maintaining water balance

  albumin
• blood cell formation occurs in the

  myebid tissue (red bone marrow)
• vital role in clotting

  fibrinogen
• stem cell

  hematocytoblasts
• involved in production of antibodies

  lymphocytes
• red cells destroyed

  hemolytic anemia
• inherited clotting disorder - recessive gene on x chromosome -main symptom : tendency to hemorrhage. is hemophilia
• type of cancer - overproduction of WBC (leukocytes)- susceptible to infections , anemia , and excessive bleeding 


  leukemia
• caused by four factors - decrease of erythrocytes - decrease of hemoglobin in RBC- deficiency of normal hemoglobin- production of abnormal hemoglobin - causes in fatigue, shortness of breath, pale skin.


  anemia
• most common in african americans -erythrocytes have abnormal sickle shape and cannot carry enough oxygen.


  sickle cell anemia
• hemoglobin production suppressed 


  thalassemia
• blood poisoning caused by infection of microorganisms and toxins in their blood 


  septicemia
• caused by injection protozoan - plasmodium by a female mosquito 


  malaria
• number of thrombocytes or blood platelets -results in long term bleeding of capillaries 


  thrombocytopenia
• also called polycythemia - caused by excessive amount of red blood cells- defect in the stem cell - leads to hypertension or high blood pressure 


  erythrocytosis
