 Standard of Competence  Students are able to interpret the cellular organization

  

linking network structure and function in plant organ systems of animals and their application in the context of science, environment, technology and society. Basic Competence Describe the component and function of tissues in animals. Indicators Students can explain the component and function of blood.

Blood is the body fluid that is found in the heart and blood vessels

Red Blood Cell (Erythrocyte)

White Blood Cell (Leucocyte) Platelets (Thrombocyte)

 Oxygen supply to tissues (bound to hemoglobin, 

which is carried in red cells) Supply of nutrients such as glucose, amino acids, and fatty acids (dissolved in the blood or bound to plasma proteins (eg, blood fat)) Disposal of waste such as carbon dioxide, urea, and lactic acid Immunological functions, including circulation of white blood cells, and detection of foreign material by antibodies Coagulation, which is one part of the self-repair mechanisms of the body (blood clots after an open wound to stop bleeding)

 Transport functions, including the transport of

hormones and signaling of tissue damage  PH regulatory body  Regulating the body's core temperature  Hydraulic functions

Description: - 4-6 million per mm3 blood - Bright red to dark purple - Biconcave disks without nuclei - Red blood cell can live of about 120 days - Old red blood cell breake down in lymph Source: Red bone marrow Function: transport O2 and help transport CO2

Description : -4,000-11,000 per mm3 blood - Separate into 2 kind: Granular leucocyte (Basophil, eosinophil, neutrophil) Agranular leucocyte ( Lymphocyte, Monocyte) Function : Fight infection Source : Red bone marrow

Description: - 150,000-300,000 per mm3 blood - Disk shaped cell fragments - With no nuclei - Purple granules in cytoplasm Source: Red bone marrow Function: aid clotting

The scheme of blood freezing process: If someone experience is hurt and releases blood

The thrombocyte that broke


Vit K, Ca+
