a decrease in the oxygen-carrying capacity of the blood cause be a decrease in RBC's or a problem with hemoglobin content. There are many types of anemia but symptoms are common including dyspnea, weakness, tachycardia, pallor and hypertension.
the most common type of anemia resulting from decreased intake, increased demand or the inability to properly absorb iron.
increased and premature destruction of RBC's, commonly resulting in jaundice.
anemia due to chronic or acute blood loss
types of anemia:
a decrease of all 3 cell lines associated with bone marrow failure caused by radiation, a virus or medications
folic acid deficiency
types of anemia:
insufficient folic acid intake causing decreased production and life span
types of anemia:
low levels of vitamin B12 or lack of intrinsic factor in the stomach, which helps absorption of B12
sickle cell anemia
types of anemia:
a genetic disorder in people of African descent where RBC's change shape when oxygen is low and then cannot move freely in capillaries. This causes severe pain, internal bleeding and organ damage.
cells, structures and functions
hematic/lymphatic: These systems share common ___________________________
viruses and bacteria
Blood is the source of certain immune cells that locate, identify and destroy disease causing agents (pathogens) such as ________________.
lymph vessels and blood vessels
immune cells rely on ___________________ to deliver their protective benefits to the entire body.
Immune cells (lymphocytes and macrophages) also used lymph structures (the spleen and nodes) to provide temporary or permanent __________________.
The ________________ operates in close association with blood returning lymph and immune substances back to the circulatory system for redelivery to the entire body.
tissue fluid, lymphatic capillary
lymph is essentially ______________ that has entered the ____________________.
blood plasma, plasma proteins
Tissue fluid originates from _____________ and has much the same composition (nutrients, gases and hormones) but not ______________.
occur in groups or chains along the paths of the larger lymphatic vessels
the bone marrow releases lymphocytes into circulation and the thymus processes these undifferentiated lymphs into T cells (ie. they become immunocompetent)
primary functions of nodes are filtering harmful particles from lymph and immune surveillance provided by _______________ and _____________________ "stationed" in the lymph nodes
note: the _______ filters blood but is NOT an organ of the lymphatic system.
- the largest lymphatic organ
- filters debris and foreign particles such as bacteria
- destroy's old RBC's
- Acts as a reservoir for healthy RBC's and platelets to be placed into circulation when needed (for example when oxygen concentration is low)
