Exam 1 - Anatomy & Physiology 2 (Ch. 17-19 K-Know U-
Understand) Questions With Complete Solutions
K- 1) Describe atrial systole Correct Answers Atrial contraction
Pressure inside atria > ventricle
AV OPEN
Following atrial systole, the ventricle reaches its maximum
blood volume, this is called EDV
K- 2) Early ventricular systole Correct Answers Ventricular
contraction
Great vessels > ventricular pressure > atria
At constant EDV
AV/SL CLOSED
K- 3) Late ventricular systole Correct Answers Ventricular
pressure >> greater vessels and atria
Blood volume is decreasing as SV is ejected, ESV is leftover
blood
AV CLOSED
SL OPEN
K- 4) Early ventricular diastole Correct Answers Ventricle
relaxation
Great vessels > ventricular pressure > atria
Constant at ESV
AV/SL CLOSED
K- 5) Atrial diastole Correct Answers Atrial pressure <
ventricles
Ventricular blood volume is decreasing
,AV OPEN
K- 6) Late ventricular diastole Correct Answers Ventricular
pressure << atria and ventricles
Ventricles blood volume is increasing passively
AV OPEN
SL CLOSED
K- A mutation that causes a conformational change in
hemoglobin protein chains and decreases their ability to bind
and transport oxygen is known as: Correct Answers
Thalassemia
K- APGAR test Correct Answers Appearance, pulse, grimace,
activity, respiratory effort
K- Arterial compliance and elasticity Correct Answers Arteries
are less compliant and more elastic, this allows them to be good
pressure reservoirs
K- Blood is a component of which fluid compartment? Correct
Answers Extracellular fluid
K- Blood type is the same as Correct Answers The antigens on
the RBC's surface
K- Blood vessels have three categories: Correct Answers
Arteries, veins, capillaries
K- Boyle's law Correct Answers Pressure and volume have an
inverse relationship
,K- Bradycardia Correct Answers Heart rate too slow
K- Capillaries are not distributed randomly, how are they
distributed? Correct Answers Networks of vessels known as
capillary beds
K- Cardioacceleratory innervates via what kind of neuron?
Correct Answers Sympathetic
K- Cardioinhibitory innervates via what kind of neuron? Correct
Answers Parasympathetic
K- Characteristics of Leukocytes Correct Answers Nucleated,
ameboid motion, chemotaxis, move via diapedesis and
margination
K- Characteristics of the basophil Correct Answers Basophils
support infections
Secrete serotonin, heparin, histamine, and prostaglandins
Mediate inflammation
Anaphylaxis, allergies
Bi-lobed, dark purple/blue stain
K- Characteristics of the eosinophil Correct Answers Attack
parasites
Regulate inflammation, increase in times of allergic reactions to
degrade histamines
Asthma, allergies
, Bilobed, stain bright red with eosin (acidic)
K- Characteristics of the lymphocyte Correct Answers
Differentiate into B and T lymphocytes
Small, single nucleus, dark blue/purple stain
K- Characteristics of the monocyte Correct Answers Transform
into macrophages after exiting the bloodstream
Inflammatory macrophages move to infections to engulf
pathogens
Anti inflammatory macrophages stay in the CT to prevent the
pathogens from entering the bloodstream.
Large, U-shaped nucleus, dark purple/blue stain
K- Characteristics of the neutrophil Correct Answers Their
granules contain hydrolytic enzymes, defensins, and lysosomes,
which are all effective in combatting bacteria. They are the
initial cells at infections and can cause oxidative bursts.
Large, polymorphonuclear, light purple stain
K- Characterizations of sickle cells Correct Answers They are
sickle shaped, sticky, unable to hold oxygen well, prone to
apoptosis
K- CO equation Correct Answers CO = SV * HR
K- Compared to women, men have Correct Answers More
blood and more blood cells (hematocrit)
