In the primitive heart (around 18-19 days) the primitive ventricle is on top of the primitive atrium
True
False
Which do all cardiac veins empty into the coronary sinus EXCEPT?
great cardiac vein
anterior cardiac vein
posterior cardiac vein
middle cardiac vein
If there is a fracture in the surgical neck of the humerus which artery is at risk for rupture?
a. subscapularis
a. circumflexa humeri posterior
a. circumflexa humeri anterior
a. profunda brachii
a. epigastrica superficialis is NOT derived from which artery ?
a. femoralis
a. poplitea
abdominal aorta
a. glutes superior
glutes inferior supplies superior gluteal muscles
True
False
Fenestrated capillaries appears on? EXCEPT
Kidney
small intestine
endocrine gland
bone marrow
Right lymphatic duct collect lymph from the upper right quadrant of the body?
True
False
The epicardium is composed of endothelium and subendocardium connective tissue
True
False
The degree of fiber stretch as a result of quantity of the blood in the ventricle prior to contraction
Afterload
Preload
Resistance
Contractility
Rising phase of action potential within the pacemaker is cells is caused by?
Ca2+
Na+
Parasympathetic effects on the pacemaker cells?
Increased permeability of the potassium
Binding of the epinephrine to b1 adrenergic receptor
Increased frequency of action potential
Increased contractility
what happened if there are enough acetyl coa from beta oxidation of fatty acids?
pyruvate dehydrogenase inhibited so glycolysis is not performed
citrate is inhibited so phosphofructokinase can produce pyruvate
lactate will be produced because it is a sign of anoxia
chylomicrons containing LDL will not be taken from blood
where does vldl come from?
lipid in the diet packed into apo B
lipogenesis of excess sugar in the liver
failure in regulation of coagulation cascade
oxidative stress of endothelium
How is lactate produced, and why is it used?
in anoxic condition, NADH reduces pyruvate to lactate so that glucose is used in vital organs
beta oxidation produces 1 acetyl coa and a fatty acyl group
Dehydrogenation of fatty acyl coa creates FADH2 and a fatty acyl group. This causes lactic acidosis thus lactate is uptaken by liver
so that brain can use lactate as energy
CK-MB is increased 6 hours after heart attack and regress in 24 hours
True
False
LDL not captured by liver via apoB 100 will be taken by tissues to make hormones
True
False
Blood flow in capillary beds has a higher velocity than in the aorta because the diameter of all capillary beds combined is greater than in the aorta
True
False
blood flow is determined by ohm’s law
True
False
Which is the formula of mean arterial pressure?
diastolic pressure + ⅓ systolic pressure
diastolic pressure + ½ pulse pressure
diastolic pressure + ⅓ pulse pressure
diastolic pressure + ⅓ cardiac output
You are given two blood vessels. radius in blood vessel A is 1 cm and blood vessel b is 2 cm. Assuming the length of two blood vessels is the same and the viscosity of blood is constant, which statement below is correct?
The resistance in blood vessel A is 4 times higher than in blood vessel B
The resistance in blood vessel A is 16 times higher than in blood vessel B
The flow in blood vessel A is 16 times higher than in blood vessel B
The flow in blood vessel B is 4 times less than in blood vessel A
What is the physiological response in humans if blood pressure is high?
rate of firing in afferent nerves increased, activating cardiovascular center, decreasing sympathetic nerve activity to decrease heart rate and stroke volume
rate of firing in afferent nerves decreased, deactivating cardiovascular center, decreasing sympathetic nerve activity to increase heart rate and stroke volume
rate of firing in afferent nerves decreased, deactivating cardiovascular center, decreasing sympathetic nerve activity to increase preload and vasoconstrict the blood vessels
rate of firing in afferent nerves decreased, deactivating the cardiovascular center, decreasing sympathetic nerve activity to increase contractility and vasodilate the blood vessels
Which of the following is NOT an ischemic heart disease?
Angina pectoris
Myocardial infarction
Tetralogy of Fallot
Sudden cardiac death
Rheumatic heart disease is caused by the same pathogen as post streptococcal glomerulonephritis
True
False
Which of the following is NOT host factors of infective endocarditis?
Malignancy
DM
Obesity
Immunodeficiency
Women are more likely to get atherosclerosis than men
True
False
Which is true regarding Buerger's disease?
Develop before 40 years of age
One of the symptoms is a pain in the shoulder
inflammation is present in small and medium arteries
accompanied by mild pain at rest
What defines heart failure?
a clinical syndrome in a patient due to inherited or acquired abnormality of structures or function of the heart develop clinical symptoms (dyspnea and fatigue) and signs (edema and rales)
Damage or death of an area of cardiac muscle (myocardium) due to blockage of blood supply to that area
inflammation that causes thickening and hardening of artery walls caused by deposits of cholesterol-lipid-calcium plaque in the lining of vessel wall
When you get rejected by your crush
What is the golden standard of acute myocardial infarction lab diagnosis?
BNP
Increased ASTO
Troponin
Benedict test
A patient was brought to RS Bunda Margonda because she felt in pain lately. She was diagnosed with congestive heart failure and it was found that she was suffering from dyspnea and anginal pain. She has physical activity limitations but she is still comfortable when she rests. What is the classification of her condition?
Class I
Class II
Class III
Class IV
A patient did a laboratory test because he was kepo. Turns out, his CTN level is 0.60 ng/ml. What does it mean?
High risk of AMI
Intermediate risk of AMI
High risk of Arteriosclerosis
Intermediate risk of Arteriosclerosis
Which one is the correct outline process of atherosclerosis?

In patients who have had heart valve surgery, the incidence of S. aureus, S. epidermidis, and gram-negative bacilli infections is higher.
True
