Title: Blood


1
Blood!
By Tiffany Woodard and Tony Perkins
2
  • Plasma - The nonliving fluid component of blood
    within which formed elements and various solutes
    are suspended and circulated.
  • 90 water with 100 different dissolved solutes

Oh yeah! Plasma is 8 plasma proteins!
  • 60 albumin - carrier for certain molecules,
    buffer, major in contributing to osmotic pressure
    along with Na

3
Coming Up...
Red Blood Cells!
4
Red Blood Cells
  • Also called erythrocytes, red blood cells are
    small cells, about 7.5 um in diameter, that are
    basically containers of hemoglobin.
  • They pick up oxygen in the capillary beds of the
    lungs and release it to tissue cells across
    other capillaries throughout the body.
    They also transport some 20 of the
    carbon dioxide released by tissue
    cells in the opposite direction.
  • Function - gas transport (1 billion O2
    each) produce ATP anaerobically
    hemoglobin

5
  • Hemoglobin - Oxygen transporting components of
    erythrocytes.
  • It is made up of the protein globin bound to the
    red heme pigment
  • Each hemoglobin can transport four molecules of
    oxygen

6
And Now...on to
White Blood Cell
Neutrophil
Eosinophil
Lymphocytes
Basophil
Monocytes
White Blood Cells
Germ
7
  • Most abundant type of white blood cell
  • Twice as large as Erythrocytes
  • The cytoplasm stains pale lilac and contains very
    fine granules
  • Origin - bone marrow
  • Function - most numerous numbers up with
    bacterial infections phagocytize bacteria and
    some fungi contain defensins

8
  • Accounts for 1 to 4 of all leukocytes and is
    about the size of a neutrophil
  • Has a blue-rednucleus that looks like a
    telephonereceiver
  • It has large, red granules
  • Origin - bone marrow
  • Function - kill parasitic worms destroy
    antigen-antibody complexes inactivate some
    inflammatory chemicals of allergies

9
Basophil
  • The Rarest white blood cells
  • Basophil means base loving
  • Granulated cells similar to Basophil cells are
    called mast cells
  • Origin - bone marrow
  • Function - rarest release histamine and other
    mediators of inflammation contain heparin, an
    anticoagulant, that acts as a vasodilator

Histamine
10
Lymphocyte
  • Plays a crucial role in immunity
  • Acts against virus infected cells and tumor cells
  • B-Lymphocytes give rise to plasma cells, which
    produce antibodies
  • It has a large, dark purple nucleus that occupies
    most of the cell volume
  • Origin - bone marrow, lymph nodes,spleen
  • Function - mount immune response by direct cell
    attack or via antibodies

11
Monocytes
  • Have abundant gray-blue cytoplasm and a darkly
    staining blue-purple nucleus which is a U or
    kidney shape
  • They turn into highly mobile macrophages, that
    are crucial in the bodys defense against viruses
  • Origin - bone marrow
  • Function - Increase during chronic infections
    phagocytosis develop into macrophages in
    tissues attack viruses and certain intracellular
    bacterial parasites

12
Platelets
  • Each platelet exhibits a blue-staining outer
    region and inner area containing granules that
    stain purple
  • Have a lot of chemicals that act in clotting
  • Sometimes called thrombocytes
  • They stick to the damage site, and form a
    temporary plug that helps seal the break
  • They age quickly and regenerate in about 10 days
  • Origin - bone marrow
  • Function - critical role in blood clotting

13
ABO Blood Groups
  • They are the types of blood people can have
  • You can have A, B, AB, or O blood
  • They are based on the presence of agglutinogens,
    type A and type B
  • Unique to the ABO blood groups is the presence in
    the plasma of preformed antibodies called
    agglutimins, which act against RBCs carrying ABO
    antigens that are not present in a persons own
    red blood cells

14
Anemia
Normal
Anemic
  • Anemia is a condition in which the blood has an
    abnormally low oxygen-carrying capacity.
    Individuals are fatigued, often short of breath
    and chilly.
  • There are three causes for anemia
  • (1) Insufficient numbers of red blood cells
    causing Hemorrhagic, Hemolytic, and Aplastic
    Anemias.
  • (2) Decreases in hemoglobin content causing
    Iron-deficiency Anemia and Pernicious Anemia.
  • (3) Abnormal hemoglobin causing Thalassemias and
    sickle-cell anemia.

15
White Blood Cell Disorders
  • Leukemia A group of cancerous conditions of
    white blood cells. It is caused by cancerous
    leukocytes, which cause the bone marrow to become
    almost completely occupied. Symptoms are fever,
    weight loss, and bone pain. It is particularly
    dangerous because it can cause internal
    hemorrhaging. Treatments involve irradiation,
    administration of antileukemic drugs, and bone
    marrow transplants.

Leukemia
  • Mononucleosis (a.k.a. the kissing disease) It is
    a highly contagious viral disease seen in
    children and young adults. It has excessive
    numbers of granulocytes which are atypical.
    Symptoms are tiredness, aching, sore throat, and
    low grade fever. It usually runs its course in a
    few weeks.
