Cardiovascular Anatomy
This part of the heart points toward the left hip
Apex
Blood flows from the left atrium to the left ventricle through this valve
Bicuspid valve (aka mitral)
A rapid heart rate over 100 PBM
tachycardia
A person's blood type is determined by the
specific antigens
What is the first phase of blood clotting?
Vascular
This vessel carries deoxygenated blood from the heart to the lungs
Pulmonary artery
What is the function of the AV valves
prevent black flow into the atria when ventricles contract
the measure of blood pressure in the arteries during ventricular contraction
Systolic Pressure
What special protein allows oxygen to bind to red blood cells?
hemoglobin
The term for longer and smaller diameter vessels create more resistance to blood flow
vascular resistance
What is the mediastinum
the middle cavity of the thorax where the heart is located
The first sound of the heart (the lub) is associated with
the closing of the tricuspid and bicuspid valves
Does the AV node impulse beat faster or slower than the SA node?
slower
This plasma protein stays in the blood to maintain osmotic pressure
albumin
The term for a blood clot breaking down
Which vessel delviers blood to the heart from the lower half of the body?
inferior vena cava
valves are found in what types of blood vessels to prevent backflow
veins (and lymphatics)
The QRS complex on an EKG represents what
the depolarization of the ventricles
This plasma protein is involved in blood clotting
fibrinogen
The term for blood flow slowing due to more particles/thickening of the blood
viscosity (low viscosity)
the_____ anchor the atrioventricular valves to the walls of the ventricles
chordae tendinae
Which valve is passed through first in the pathway of blood through the heart?
Tricuspid valve
The pacemaker of the heart
SA node
The EKG wave that represents depolarization of the atria
P wave
A pressure gradient in blood refers to what?
The difference in vessel pressure- liquid will flow from an area of higher pressure to an area of lower pressure
