This is the largest artery in the body.
Pulmonary
Atrium
Ventricle
Aorta
The cusps (leaflets) of atrioventricular valves attach directly to
papillary muscles.
trabeculae carneae
chordae tennidae
interatrial septa
After blood leaves the capillaries, it enters the
arteries.
arterioles.
venules.
What would happen if a small hole developed in the septum?
The heart would stop pumping.
Blood would move between the right and left side of the heart.
The blood from the pulmonary artery would enter the aorta.
Blood would not flow into the coronary arteries
Why is a myocardial infarction life threatening?
A damaged heart muscle cannot pump blood efficiently.
Swollen veins lose elasticity, which decreases blood flow to vital organs.
A minor bump or fall could lead to internal bleediing.
It inhibits the exchange of oxygen and carbon dioxide in body cells.
Which blood pressure reading would be considered healthy?l
140/90
80/50
120/70
160/100
What vessels carry deoxygenated blood away from the heart?
Neither coronary arteries or pulmonary artery
Pulmonary artery only
Both coronary arteries and pulmonary artery
Coronary arteries only
What is a ballooning out of, or saclike formation in the wall or an artery called?
Anemia
Arteriosclerosis
Atherosclerosis
Aneurysm
What is known as the "pacemaker" because it initiates the heartbeat?
Bundle of His
AV node
SA node
Purkinje fibers
Smooth layer of cells lining the inside of the heart
Pericardium
Myocardium
Endocardium
Epicardium
Muscular middle layer of the heart
Pericardium
Myocardium
Endocardium
Epicardium
Vasodilation is a(n):
increase in the diameter of a blood vessel
drug that dilates the blood vessels
decrease in the diameter of a blood vessel
synonym for vasoconstriction
Which of the following describes the pathway of the intrinsic nodal (electrical) system?
AV node -> SA node-> Purkinjie fibers -> AV bundles -> Bundle branches
SA node->AV node-> Purkinje fibers -AV bundle
SA node -> AV node -> AV bundle-> Bundle branches -> Purkinje fibers
AV node -> SA node-> Purkinjie fibers -> bundle branches -> AV bundble
Average heart rate for a healthy adult should be what?
120
140
55
70
What does this picture show?
Atherosclerosis
High Cholesterol
High HDL Cholesterol
Circulatory System
term for slow heart rate (less than 60 beats per minute)
Bradycardia
Tachycardia
Term used to discuss any change or deviation from the normal rate or rhythm of the heart
Arrhythmia
Aneurysm
Hematoma
Sickle cell anemia
This blood vessel lies in the groove on the front & back of the heart to supply it with fresh blood that is full of nutrients & oxygen.
Pulmonary artery
Aorta
Pulmonary veins
Coronary artery
What is ECG?
electrocardiogram
a tool that collects electrical changes in the heart muscle
will detect any abnormal rhythm of the heart
all of the above
Referring to an Electrocardiogram, what is occurring during the "P-wave"
Atrial Depolarization
Ventricle Repolarization
Ventricle Depolarization
Atrial Repolarization
The function of hemoglobin is to
carry oxygen
protect the body against infection
produce the spleen
all the above
What is the function (job) of the platelets?
To form clots (i.e. scabs) when you have cuts and grazes.
To transport oxygen to the muscles
To carry dissolved sugars.
To produce antibodies
Which cell engulfs and digests bacteria/pathogens?
lymphocytes
phagocytes
platelets
Which cell releases antibodies to the blood?
phagocytes
lymphocytes
platelets
What destroys pathogens?
antibodies
red blood cells
platelets
plasma
Platelets are also known as
leukocytes
erthryocytes
thrombocytes
monocytes
What is the function (job) of the plasma?
To release antibodies to fight infections.
To transport oxygen around the body.
To carry dissolved nutrients and sugars.
To transport oxygen around the body.
What is the process of blood cells being produced called?
homeostasis
hematopoiesis
hemostasis
homogeneous
What hormone controls the rate at which new red blood cells are produced?
erythropoietin
interleukin
TSH
What is the function of a basophil?
Plays a major role in allergic response by producing histamine; also produces heparin to control blood clotting
Functions specifically to combat parasitic infection, they also help to promote inflammation and play a role in allergic reactions
One of the first responders in the immune system, it phagocytoses pathogens and may present the phagocytosed antigens to other immune cells
Helps the blood clotting process by gathering at the site of an injury, sticking to the lining of the injured blood vessel, and forming a platform on which blood coagulation can occur
Functions in transport and gas exchange
