Blood has a variety of functions, which one is not a function of blood
Maintaining body temperature by absorbing and distributing heat
Preventing infections
Transport metabolic waste to lungs and kidneys for elimination
Carrying oxygen from the cells to the lungs
These are all functions of blood
Buffy coat consists of
WBC
Plasma
Erythrocytes
Platlets
Most significant protein found in blood plasma and is a major contributor to osmotic pressure
Globulins
Albumin
Fibrinogen
Hemoglobin
How many oxygen molecules can a single hemoglobin carry?
2
4
1
8
Which structure releases EPO?
Kidneys
Bone Marrow
Spleen
Pancreas
An increase in EPO would cause BP to
Increase
Decrease
Remain the Same
You encounter a patient with a bacterial infection, what WBC count would you find abnormal?
Lymphocytes
Monocytes
Neutrophils
Basophils
An abnormal T lymphocyte count indicates
Production of antibodies
Asthma
Inflammation
Potential Tumor
Viewing a specimen under the microscope you find a parasite, this patient's _____________ would be abnormally high
Eosinophils
Basophils
Lymphocytes
Neutrophils
Vaccines are designed to trigger antibody production. The goal is to stimulate what WBC?
Eosinophils
B Lymphocytes
Monocytes
Neutrophils
All WBC come from myeloid stem cells
True
False
The correct sequence of events in coagulation would be
Prothrombin -> Thrombin -> Fibrinogen -> Fibrin
Prothrombin -> Prothrombin Activator -> Fibrinogen -> Fibrin
Prothrombin -> Fibrinogen -> Thrombin -> Fibrin
Fibrinogen -> Fibrin -> Prothrombin -> Thrombin
In activation of prothrombin, Factor X will be coupled with _______ to form prothrombin activator
Factor V
PF3
Ca2+
All are coupled with Factor X
To achieve the quickest response in coagulation it would be ideal to go through what pathway?
Extrinsic
Intrinsic
Which ion is primarily responsible for the plateau phase of the cardiac action potential?
Sodium
Potassium
Chloride
Calcium
Due to a birth defect of the circuitry of the heart causes blood to reenter the left atrium from the left ventricle. This particular birth defect affects what valve in the heart?
Tricuspid valve
Pulmonary valve
Bicuspid valve
Aortic valve
The pulmonary artery carries
Oxygenated blood to the heart
Deoxygenated blood towards the lungs
Oxygenated blood away from the heart
Deoxygenated blood away from the lung
What veins drain into the right atrium
Superior vena cava
Inferior vena cava
Coronary Sinus
Pulmonary vein
Pulmonary Trunk
Which chamber of the heart generates the highest pressure during systole?
Left ventricle
Right atrium
Left atrium
Right ventricle
Generates impulses at 75x/minutte
SA node
AV node
Bundle of His
This would be an example of
Sinus Rhythm
Junctional Rhythm
Heart Block
Arrhythmia
Absent of the T wave complex would indicate issues in
Atrial depolarization
Ventricular repolarization
Ventricular depolarization
Atrial repolarization
A patient HR reads 80 bpm and their cardiac output (CO) was determined to be 8000. What is the stroke volume?
(a)
If there is increased vagal stimulation to the heart, how does cardiac output change?
Increase
Decrease
Remain the Same
An increase in afterload would cause SV to
Increase
Decrease
Remain the same
An increase in SV could be associated with
EDV decreases
Increase in preload
ESV increase
Decreasing contractility
An increase in ESV would cause CO
Increase
Decrease
Stay the same
Which of the following changes would decrease myocardial oxygen demand?
Increased heart rate
Increased contractility
Decreased preload
Increased afterload
A person with uncontrolled hypertension over a long period of time would have direct consequences on their
Kidneys
Liver
Brain
Heart
If the fluid is not exiting the capillaries what might be effected
Osmotic pressure
Hydrostatic pressure
Systolic pressure
Which one is not associated with resistance
Blood viscosity
Vessel length
Vessel Diameter
All are associated with resistance
If baroreceptor firing increase, what happens to total peripheral resistance
Increase
Decrease
Remain the same
Which of the following would lead to an increase in venous return?
Standing still for prolonged periods
Increased skeletal muscle contraction
Decreased blood volume
Increased intrathoracic pressure
When total peripheral resistance increases, what happens to mean arterial pressure
Increase
Decrease
Remain the same
Firing of cardioinhibitory center causes CO
Increase
Decrease
Remain the same
If arterial compliance decreases, how does systolic blood pressure change
Increase
Decrease
No effect
What causes fluid to exit capillaries into tissues?
Osmotic pressure greater than hydrostatic pressure
Net filtration pressure equaling zero
Hydrostatic pressure greater than osmotic pressure
Albumin
From arteriole to venule, the osmotic pressure of the capillary
Increases
Decreases
Remain the same
After the review, 1-10, how prepared do we feel about the exam?
1-2
3-4
5-6
7-8
