Chapter 5 Flashcards
chemical that melts a clot is
thrombolytics
What shape is a healthy red blood cell?
Discs - thinner in middle than the edges
another name for endothelial lining of blood vessels
tunica intima
nutrient at the center of the hemoglobin molecule
iron
type of anemia, bone marrow activity is suppressed or non-existent, all types of blood cells are in short supply
aplastic anemia
another term for stasis thrombosis
Coach Class Syndrome
clot or piece of debris that travels on the arterial side of the systemic circuit will always end up where
anywhere but the lungs
possible complication of a large intramuscular hematoma
myositis ossificans
genetic disorder resulting in insufficient supply of important clotting factors is?
hemophilia
Blood leaks into a joint space because of poor clotting is the result of what disorder?
Hemophilic arthritis
Thrombocytopenia
decreased number of thrombocytes
Feature that distinguishes myeloma from other forms of blood cancer
significant bone damage
What condition is an autosomal recessive disease leading to the production of abnormal hemoglobin
sickle cell disease
What is sickle cell crisis
infarction that kills healthy tissues
What is a Virchow triad
injury to endothelium, hyper-coagulability, venous stasis (slow blood flow)
Condition that occurs when BIGGEST of the arteries becomes weak and inelastic and may bulge
aortic aneurysm
How can abdominal aneurysm cause severe back pain
can press against spine and nerve
Condition where deposits of cholesterol and other substances infiltrate and weaken layers of large and medium-sized blood vessels, particularly the aorta and coronary arteries
atherosclerosis
Foam cells send with atherosclerosis begin as
cholesterol filled monocytes
chest pain associated with atherosclerosis and risk of heart attack is called
angina pectoris
most common type of hypertension
essential hypertension
chronic hypertension is most likely to lead to?
vision problems (retinopathy)
Raynaud phenomenon is a symptom or complication of what disorders
scleroderma & lupus (and other autoimmune connective tissue diseases)
Signs and symptoms of a Raynaud syndrome episode
waves of pallor, cyanosis & flushing of hands or feet
Deep veins are less susceptible to varicosities than superficial veins because
deep veins are supported by external skeletal muscle
Leading cause of heart attack
ischemic attack that kills off portion of the myocardium
blood vessel involved in a heart attack
coronary arteries
What does heart failure mean?
heart cannot work hard enough
What is right-sided heart failure?
ventricle cannot pump efficiently, fluid accumulates in extremities
Which of following deficiencies may cause nutritional anemia
Vitamin B-12
Tissue that is damaged first in chronic hypertension
arterial walls
which of the following is a controllable risk factor for the development of atherosclerosis
smoking
what is the difference between primary and secondary Raynaud syndrome
Secondary is reaction to an underlying problem
What factor determines the severity of a heart attack?
The length of time blood supply is deprived
what is a temporary circulatory complication of some other condition, such as pregnancy, kidney problems, adrenal tumor, or hormonal disorder
secondary hypertension
sometimes called spider veins - permanently dilated capillaries & venules appear on ankles & legs and usually harmless
telangiactasias
