Q

Pathway of air

A

Air enters through the nose or mouth
Travels down the trachea
Branches into two bronchi leading to the lungs
In the lungs the air moved into the alveoli where gas exchange occurs

Q

Endocardium

A

inner layer of the heart wall

19
Q

Myocardium

A

muscular inner layer of the heart wall

20
Q

Epicardium

A

Protective sac that covers the heart

21
Q

Atrium

A

top chambers of the heart, left and right

22
Q

Ventricles

A

Bottom chambers of the heart, left and right

23
Q

Right atrium

A

receive oxygen poor blood from the superior and inferior vena cava, pumps blood into the right ventricle

24
Right Ventricle
receives oxygen poor blood from the right atrium, pumps the oxygen poor blood to the lungs through the pulmonary artery to reload the blood with oxygen
25
Heart Valves
Open and close to allow blood flow through and keep blood from moving in the wrong direction
26
Atrioventricular valves
AV valve open between the atria and ventricles
27
Tricuspid valve
the valve between the right atrium and the right ventricle
28
Mitral (bicuspid) valve
valve between left atrium and left ventricle
29
Semilunar valves
valves that open when blood flows out of the ventricles
30
Aortic Valve
opens when blood flows out of the left ventricle to the aorta
31
Pulmonary Valve
opens when blood flows from the right ventricle to the pulmonary arteries
32
Capillary
connect your arteries to your veins, one cell thick, where gas exchange occurs
33
Heart sounds
produced by the closure of the heart valves, described as "lub-dub" sounds
34
S1
Lub, closure of the atrioventricular valves
35
S2
Dub, closure of the semilunar valves
36
Pulse
rhythmic throbbing of the arteries caused by expansion and contraction of the heart as it pumps blood. A way to measure heart rate, normal pulse rate 60-100 beats per minute
37
Iron
a mineral essential to the production of hemoglobin, found in red blood cells and helps carry oxygen to the tissues
38
Anemia
a condition where blood doesn't have enough healthy red blood cells to carry sufficient oxygen to your body tissues
39
Iron deficiency anemia
a type of anemia due to insufficient iron leading to the production of less hemoglobin.
40
Pulse Oximetry
measures the oxygen level (oxygen saturation) of the blood using a probe placed on the finger
41
Probe
device that uses light to measure how much oxygen is in the blood
42
Blood Pressure
the pressure of circulating blood against the walls of blood vessels, measured by systolic and diastolic pressure. normal = 120/80
43
Systolic Blood Pressure
the first number in blood pressure, the pressure pushing against your artery walls when the heart beats
44
Diastolic blood pressure
second number in blood pressure, the pressure your blood is pushing against your artery walls while the heart muscle rests between beats
45
Hypertension
high blood pressure
