Erythrocyte
|
Red blood cells that are necessary for carrying oxygen to the body cells
|
|
Reticulocytes
|
Erythrocytes (red blood cells) that haven't reached maturity (grown to adulthood) that escape and get into the blood circulation
|
|
Leukocyte
|
White blood cells that have the job of protecting the body from infection by getting around bacteria and eating it (phagocytosis)
|
|
Thrombocyte
|
Blood platelets that are necessary for blood to clot (or stop flowing) to prevent bleeding to death
|
|
Plasma
|
The liquid portion of the blood that carries the blood cells
|
|
Stem cell
|
A special cell found in the bone marrow that all cells begin from.
|
|
Erythropoietin
|
The process of making red blood cells or erythrocytes. It is released into the body when more red blood cells are needed. During exercise, rise in temperature
|
|
Hemoglobin
|
Hemoglobin is the red pigment that carries oxygen and is found in erythrocytes.
|
|
Oxyhemoglobin
|
Hemoglobin that is saturated (full and can hold no more) with oxygen
|
|
Composition of blood
|
Blood is 55% plasma and 45% blood cells.
Plasma is 92% water and 8% proteins, ions, sugars,amino acids and nitrogen waste |
|
Four functions of blood
|
Maintain amount of water in tissues
Maintain body temperature Protect acid-base balance in body Carry food, oxygen, carbon dioxide and waste in and out of cells |
|
Difference between adult and fetal hemoglobin
|
Fetal hemoglobin can be saturated with oxygen at a lower oxygen tension
|
|
Anticoagulant
|
Prevents blood from clotting and is used to prevent strokes and blood clots in the body
|
|
Blood clots involve
|
Vitamin K
Fibrin insoluble protein Calcium ions Enzyme ?? |
|
Functions and types of white blood cells (Leukocytes)
|
Phagocytes-engulf (eat) bacteria to protect body from infection
Granulocytes are phagocytes Types of granulocytes-neutrphils (Phagocytes), eosinphils (antigen-antibody complexes), basophils (store histamine) Agranulocytes are also white blood cells (Lympocytes (synthesis of antibodies) Monocytes-form macrophages for phagocytosis |
