- Side 3

- Blood is composed of two major components; What are they?
- Plasma and suspended cells
- Plasma contains:
- H2O, Inorganic salts, organic matter, gases, proteins and antibodies
- Cells contain:
- Leukocytes (white blood cells)
  Erythrocytes (red blood cells)
  Thrombocytes (platelets)
- how many leukocytes circulating in the bood stream?
- 3,500 to 12,500
- Leukocytes are catergorized into two groups, these are ... ?
- Agranulocytes and Granulocytes
- Granulocytes include .. ?
- neutrophils, eosinophils, and basophils
- Agranulocytes include ...?
- Lymphocytes and monocytes
- Thrombocytes appear as ...?
- small cell fragments
- what are the most frequent cell type?
- erythrocytes
- what are erythrocytes responsible for?
- transport of oxygen to tissues and the transport of carbon dioxide t the lungs
- where do erythrocytes usually originate and mature?
- in the bone marrow
- what happens to an erythrocyte when it matures?
- the size of the cell decreases and the nucleus disappears.
- In certain disease state, RBC's can also be produced by ... ?
- liver and spleen
- What is the smallest blood cell?
- A mature RBC at about 7 um in diameter
- Name this white blood cell
- Neutrophil
- Name this white blood cell
- Eosinophil
- Name this white blood cell
- Basophil
- Name this white blood cell
- Lymphocyte
- Name this white blood cell
- Monocyte
- Thrombocytes (or platelets)
- small, irregularly shaped cell fragments that have broken away from larger cells in the bone marrow (megakaryocytes)
- the two upper chambers are the ...
- right and left ATRIA
- the two lower chambers are the ...?
- right and left VENTRICLES
- what do the ventricles do?
- they form the bulk of the heart and are the discharging chambers that push blood to various places in the body.
- Interatrial or Interventricular septum
- the wall of tissue that separates the right and left chambers longitudinally
- Deoxygenated blood comes TO the heart and is drained into the right atrium though one of two major vessels... what are they?
- the superior vena cava and the inferior vena cava
- superior vena cava
- drains blood from the upper body (head, neck, and forelimbs)
- inferior vena cava
- drains blood from the trunk and lower body
- Tricuspid Valve
- a valve with three flaps found between the right and left atrium and ventricle.
- Chordae Tendinae
- fibrous strands that attach the tricuspid valves to the muscular wall of the right ventricle
- Pulmonary Trunk
- this divides into two pulmonary artieries that convey the blood to the lungs for gas exchange
- semi-lunar valve
- a valve between the right ventricle and the pulmonary trunk that prevents the backflow of blood.
- how does oxygenated blood return to the heart?
- through two pulmonary veins
- Bicuspid valve, or the mitral valve
- a valve with two flaps; between the left atrium and left ventricle, its a chamber to prevent the backflow of blood.
