|
pericardial cavity (location & fluid)
|
a space between the parietal pericardium and the viceral pericardium
- has a small amount of fluid to help reduce friction |
|
|
|
septum (meaning)
|
separates
|
|
|
|
left ventricle thickness
|
very thick because it's the main pumper of blood in the cardiovascular system
|
|
|
|
atrioventricular valves (AV)
|
both between the atria and the ventricles
- bicuspid (left side of the heart) - tricuspid (right side of heart) |
|
|
|
Semilunar valves
|
between ventricles and great vessels
- pulmonary (between pulmonary trunk and right ventricle) - aortic (between aorta and left ventricle) |
|
|
|
Blood goes to lungs from...
|
Right side of heart
|
Which side of heart?
|
|
|
Blood goes to system/body (systemic circulation) from...
|
Left side of heart
|
Which side of heart?
|
|
|
What part of body needs the freshest blood?
|
The heart
|
|
|
|
Drains deoxygenated blood from the heart into the right atrium
|
Coronary sinus
|
|
|
|
Diastole
|
means relaxing
|
|
|
|
Systole
|
Means contraction
|
|
|
|
is the pulmonary trunk part of the pulmonary arteries?
|
No, it comes out of the heart first
|
|
|
|
In heart contraction, the atria contract first when stimulated by...
|
SA
|
what node?
|
|
|
Average time required to complete cardiac cycle is...
|
usually less than one second (about 0.8 seconds at a heart rate of 75 bpm)
|
|
|
|
Pericarditis
|
inflammation of the pericardium
|
|
|
|
Ischemia
|
lack of oxygen to heart muscle (may lead to necrosis aka. tissue death)
|
|
|
|
Heart failure
|
caused by right or left sided congestion and poor circulation to tissues and lungs
|
|
|
|
ADH (antidiuretic hormone) is released from the posterior pituitary gland in response to...
|
dehydration or decreased blood volume
|
|
|
|
ANP (Atrial naturetic peptide) is a natural diuretic polypeptide hormone released by cells of the cardiac atria to...
|
secrete sodium, lowering BP (causes a direct vasodilation)/reducing blood volume (by promoting loss of salt and water as urine)
|
|
|
|
Normal BP
|
120/80mmHg
|
|
|
|
Hypotension
|
systolic below 110mmHg (often associated with illness, low body weight)
|
|
|
|
Hypertension
|
systolic above 140mmHg (can be dangerous if chronic)
|
|
|
|
Tachycardia
|
rapid heart rate over 100 bpm
|
|
|
|
Bradycardia
|
slow heart rate less than 60 bpm
|
|
|
|
Cardiac output
|
the amount of blood pumped out of the heart per minute
- SV x HR |
|
|
|
SV (stroke volume)
|
the volume of blood pumped by each ventricle in one contraction
|
|
|
|
"lub"
|
first heart sound caused by atrioventricular valves closing (ventricular systole)
|
|
|
|
"dub"
|
Second heart sound, caused by Semilunar valves closing (early diastole)
|
|
|
|
Where do we get the freshest blood?
|
left ventricle into the ascending aorta
|
|
|
|
Primary lymph organs
|
thymus and bone marrow
|
|
|
|
Secondary lymph organs
|
spleen, lymph nodes, and other lymphoid tissues like the tonsils
|
|
|
|
2 lymphatic system functions
|
transports escaped fluid back to the blood
Plays essential role in body segregate abs resistance to disease (immunity) |
|
|
|
Properties of lymphatic vessels
|
- one way system toward the heart
- no pump - lymph moves toward tube heart via - milking action of skeletal muscles - rhythmic contraction of smooth muscle in vessel walls |
|
