Anatomy test 5 Flashcards
formed elements that are biconcave discs about 7-8 micrometers in diameter are
erythrocytes
function of hemoglobin
carries oxygen bound to heme
most abundant of leukocytes are
neutrophils
types of blood cell responsible for the immune response
white blood cells
fight infection
major disorder characterized by a reuction in the oxygen-carrying capacity of the blood is called
anemia
abnormal accumulation of fluid in the intracellular space is
edema
liquid matrix (medium) of blood is called
plasma
yellow liquid component
primary function of platelets
to form blood clots
destruction of old RBC’s is a function of the
spleen
blood flows from the superior vena cava into the
R atrium
the myocardium is made up of
cardiac muscle
thick layer
blood flows from the pulmonary veins into the
L atrium
the bicuspid valve is located between the
L atrium and L ventricle
there is a semilunar valve between the
R ventricle and pulmonary trunk
blood flows into the coronary arteries from the
aorta (ascending)
all deoxygenated blood returning from the systemic circulation flows into the
R atrium
the L ventricle wall of the heart is thicker than the right wall because
it pumps blood throughout more of the body
mitral valve
when open allows blood flow to the L ventricle
L- AV valve
tricuspid valve
prevent backflow of blood to the R atrium
R-AV valve
aortic semilunar valve
controls the flow of blood
“dupp”
pulmonary semilunar valve
pressure from the pulmonary artery closes this valve
“dupp”
venous valve
prevents reverse back flow
vena cava
brings blood from the body to the R atrium
coronary artery
carry freshly oxygenated blood directly to the heart
aorta
carries blood from the heart to all of the body except the lungs
left side of the heart
pulmonary artery
carries deoxygenated blood from the heart to lungs
pulmonary valves
prevents blood from flowing from the artery back into the heart
the tunica interna of a blood vessel is made of
endothelium
valves are present in
veins
vasoconstriction (that helps control blood pressure) occurs in the
veins
most fluid and proteins that escape from blood vessels to the interstitial fluid are normally
returned to the blood via the lymphatic system
plasma is composed of
phospholipids and proteins
mostly WATER
type O is considered the theoretical universal
blood type
no A, B antigens or ___ in the plasma
pernicious anemia
laking B12 vitamin
deficiency of production of RBC
sickle cell anemia
mutated form of hemoglobin distorts the RBC’s shape (crescent)
aplastic anemia
deficiency of RBC by failure of bone marrow development
hemolytic anemia
destruction of erythrocytes
iron-deficient anemia
insufficient absorption or intake of iron
correct sequence of parts that function to carry cardiac impulses is
- AV node
- SA node
- purkinje fibers
- bundle of His
- right and left bundle branches
humoral immunity
.
T lymphocyte
- T helper
- cytotoxic
- memory
- suppressive
- natural killers
breakdown of hemoglobin
heme and globin
agranular leukocytes that are phagocytic are the
neutrophils and monocytes
the thoracic duct empties lymph into the
left subclavian vein
specialized lymphatic capillaries call lacteals are found in
the small intestine?
T-cells and B-cells are
lymphocytes
largest lymphatic organ
spleen
antibodies are
immunoglobins
help identify and remove foreign antigens
B lymphocytes
antibody mediated immunity
T lymphocytes
cell mediated immunity
red bone marrow
stem cells give rise to undifferentiated lymphocytes
thymus
divided into lobules that contain lymphocytes
secrets thymosin
lymph node
function in immune surveillance
spleen
filters blood
red and white pulp
largest lymphatic organ
tonsils
lymph node in neck/throat
vascular resistance depends on
the pressure of blood flow
the cardiovascular center is located in the
thoracic cavity
the heart contracts during
systole
systolic pressure
a vessel that carries blood back to the heart is
coronary artery or veins
a sinus rhythm originates in the
SA node
albumin is a
plasma protein
helps maintain osmotic pressure of blood
a pigment that carries oxygen in red cells is
hemoglobin
erythropoietin is a
glycoprotein hormone
controls RBC production
serum is the
liquid portion of blood
a platelet is also called a
thrombocyte
the substance that forms a blood clot is a
platelet plug
a clot in an unbroken vessel is called a
thrombus
a floating blood clot is called a
embolus
D
the letter is D
