Blood
hemoglobin is found here
Red blood cells
These carry blood away from the heart
arteries
this is the relaxed phase of the heartbeat during which blood fills the heart
diastole
The heart consists of these 3 layers
epicardium, myocardium, endocardium
blocked blood flow to a part of the heart can cause
myocardial infarction
These destroy pathogens and remove waste from cells
white blood cells
A vein that brings deoxygenated blood into the right atrium from the body
Inferior Vena Cava
these conduct impulses to each ventricle
right and left bundle branch
a heart valve the regulated the blood flow from the left atrium into the left ventricle
mitral (bicuspid) valve
involves an abnormal increase in the number of white blood cells
Leukemia
Known as the universal donor
0-
largest artery in the body
aorta
Known as the "natural pacemaker" of the heart
SA node
A wall of tissue that devides the right and left sides of the heart
cardiac septum
A condition that occurs when the heart becomes too weak to pump efficiently and supply the needs of the body. The blood returns to the heart faster than the heart can pump it out and becomes "backed up"
Congestive heart failure
known as the universal recipient
AB+
this carries deoxygenated, nutrient-depleted blood from the fetus to the placenta?
umbilical artery
this slows the electrical signal, which allows time for the ventricles to receive blood from the atria
atrioventricular node (AV node)
the largest chamber of the heart
left ventricle
an inherited blood disoder that affects hemoglobin and the shape of RBC's causing them to move less freely through the blood, resulting in blocked blood flow
Sickle cell disease
this has proteins that help fight infection and aid the clotting process
plasma
these surround tissues and cells, they connect branches of arteries to branches of veins
capillaries
nerve fibers that send impluses to the ventricles, which causes them to contract and pump blood
Purkinje fibers
a thin, fluid-filled sac that provides lubrication for the heart and helps protect the heart from infection
pericardium
An irregular and often very rapid heart rhythm(arrhythmia) that can lead to blood clots in the heart
Atrial fibrillation (a-fib)
