Unit 1 Exam Review Flashcards
type A blood has ____ antibodies in the blood system?
type b
in adults erythropoiesis exclusively takes place in
red bone marrow
blood leaves the right ventricle by passing through the
pulmonary valve
the average life span of a red blood cell is
4 months
the hormones that may be slowly administered by intravenous drip to accelerate labor and delivery is/are
oxytocin
which of the following vitamins is needed for the formation of clotting factors?
vitamin k
coronary veins empty into the
right atrium
the normal pacemaker of the heart is located in
the sinoatrial node
which of the following hormones is/are water soluble and therefor bind to extracellular receptors?
insulin and epinephrine
which of the following is not true regarding type 1 diabetes
tissues inhibit insulin resistance
blood pressure is determined by
estimating the pressure needed to close off an artery with external pressure cuff
cardiac output is increased by
symphatetic stimulation
which of the following substances activate protein kinases and thus acts as a second messenger
ACTH
what are the layers of blood vessels from outside to inside
tuna externa; tunica media; tunica interna
____ are chemical messengers that are released by cells and transported in the bloodstream to alter the activities of specific cells in other tissues
hormones
blood colloid osmotic pressure is produced by
large non-diffusible proteins in the blood plasma
partial constriction due to constant sympathetic stimulation
vasomotor tone
an increase in the rate of action potentials from baroreceptors will trigger a reflex to
both decrease heart rate and decrease pressure
Baroreceptors are located in the
carotid and aortic sinuses and the right atrial wall
compared to arteries, veins
have thinner walls
the heart secretes the hormone
atrial natriuretic peptide
identify the vein labeled “10”
inferior vena cava
identify the vein labeled “8”
subclavin
a persons blood type is determined by the
presence of specific glycoproteins on the cell membrane
the smallest arterial branches are called the
areterioles
the pituitary hormone that promotes egg development in ovaries and sperm development in
FSH
which of the following is true of the endocrine system
it responds slowly but effectively for maintaining homeostatic functions
capillaries that have complete lining are called
continuous capillaries
hormones can be divided into different groups based on their chemistry. these categories include all of the following except
Acetylcholine derivatives
the construction phase of the cardiac cycle is called
systole
red blood cell production is regulated by the hormone
Erythropoietin
the percent fraction of formed elements relative to whole food is the
hematocrit
the t wave on and ECG training represents
ventricular repolarization
edema may occur when
the plasma concentration of protein is reduced, capillary hydrostatic pressure is elevated, and the capillary endothelium permeability goes up
venous valves are responsible for
channeling blood toward the heart
the sequence in which excitation would move through this system is
4,3,2,5,1
the most numerous white blood cells in peripheral circulation are the
neutrophilis
the volume of blood ejected from each ventricle during a contraction is called the
stroke volume
which part of the vascular system functions as a blood reservoir and contains over 60% of the body’s blood
veins
the main action of antidiuretic hormones is
increased water conservation by kidneys
each of the following is true of the pineal gland except that it
is a component of the hypothalamus
the function of hemoglobin is to
carry dissolved blood gases
the extrinsic pathway of a coagulation is initiated by the
release of tissue factor (factor III) b damaged endothelium
the process of fibrinolysis
dissolves clots
how would removal of calcium ions from a blood sample affect coagulation
coagulation would be prevented
all of the following are functions of blood except
generating action potentials
follicle cells synthesize a protein called
Thyroglobulin
the visceral pericardium is the same as the
epicardium
end-systolic is defined as the
amount of blood remaining in a ventricle after contraction
blood returning to the heart from systemic circuit first enters the
right atrium
blood colloid osmotic pressure decreases in starving children because
starvation increases the ermebility of capillaries causing decrease in BCOP
if the connection between the SA node and AV node becomes blocked,
the atria will contract more forcefully
a patient has an infected puncture wound to her foot. which type of white blood cell would you expect to be elevated in a differential white cell count
Eosinophils
one cause for insulin resistance is non-insulin dependet diabetes is
insulin receptor up-regulation
