myocardial infraction
which layer of the heart is the innermost and is smooth and allows blood to flows smoothly
endocardium
semilunar valve between right ventricle
pulmonary
atrioventricular valve on the right side
tricuspid (TRIRIGHT)
ventricular valve on the left side
bicuspid
during a heartbeat, what do the ventricles do while the atria relax
contract
where does blood enter the heart from the inferior and superior vena cavas
atria
which of these types of blood vessels contain thick muscular tissue
arteries
thrombocytes are
platelets
normal blood pressure is
120/80
this causes the blood to produce antibodies if positive
rh factor
white blood cells lifespan is
9 days
in what type of circulation does the blood flow between the heart and the lungs
pulmonary
which of these types of blood vessels are microscopic and are between arterioles and venuoles
capilliaries
red blood cells lifespan is
120 days
which of these items help form clots
platelets
platelets lifespan is
5-9 days
high blood pressure is
140/90
which layer of the heart has a lubricating fluid to reduce friction
pericardium (outermost layer)
what is the pale yellow liquid part of the blood
plasma
erythrocytes are
red blood cells (RBC)
which layer of the heart is made of muscle tissue and pumps the blood through the system
myocardium
which of these items fights disease and infection
white blood cells
vasodilation is what and when and what happens
widening of blood vessels, when you're hot (sweating) skin turns pinkish/red
which blood type is known as the universal donor
O-
during a heartbeat, what do the atria do while the ventricles contract
relax
iron or vitamin b12 supplements may be a treatment for which of these diseases
anemia
which of these types of blood vessels are tiny arteries
arterioles
extremely high blood pressure is
200/100
in what type of circulation does the blood flow between the heart and the cells of the body
systemic
which of these types of blood vessels are thin and carry deoxygenated back to heart
veins
which of these types of blood vessels are tiny veins
venuloles
leukocytes are
white blood cells (WBC)
pathway of blood to the heart
right atrium, tricuspid valve, right ventricle, pulmonary valve, left atrium, bicuspid (mitral) valve, left ventricle, aortic valve
3 layers of heart & describe
pericardium - double membrane that covers the outside of the heart
myocardium - middle & thickest layer
endocardium - smooth layer of cells that line the inside of the heart & blood vessels
vasodilation & vasoconstriction: describe, define, why, when
vasodilation: widening of blood vessels, when you're hot (sweating) skin turns pinkish/red
vasoconstriction: narrowing of blood vessels, when you're cold
compare & contrast the four chambers of the heart
ventricles: pumping chambers, blood leaves
atria: receiving chambers, blood enters
both: located in the heart
4 functions of cardiovascular system
Supplies nutrients and oxygen to the body, removes metabolic waste and carbon dioxide from cells, distributes hormones and antibodies throughout the body, helps control body temperature and electrolyte balance
what are the valve functions
keep blood flowing in one direction and it keeps it from flowing back
atrioventricular valves & the semilunar valves, location
Atrioventricular valves are located between the atria and the ventricles on each side of the heart, semilunar valves are located between the ventricles and the vessels where blood leaves the heart
scribble drawing, compare veins, capillaries, ateries, what are the tiny veins called, two largest veins, largest artery
veins - carries blood back to heart, arteries - carries blood away from the heart, capillaries - microscopic vessels where the exchange of materials takes place, superior & inferior vena casa, aorta
name scientific name for red & white blood cells & platelets, describe function, & lifespan
erythrocytes - carries oxygen to all cells & removes carbon dioxide - 90 to 120 days, leukocytes - fight disease and infection - 9 days, thrombocytes - Help form clots to prevent blood loss - 5 to 9 days
what is considered low, high, normal blood pressure
what is it called when you have high blood pressure
why is this referred to as the silent killer
90/60, 120/80, 140/90
hypertension
shows no symptoms
what is hemoglobin & what does it do
a protein in red blood cells, carries oxygen to all cells and removes carbon dioxide.
