Circulatory System Flashcards
The cardiovascular system:
- Heart & blood vessels - arteries, cappillaries, and veins.
- transport of nutrients and waste products
The lymphatic system:
- lymph, lymph nodes, and vessels
- maintains fluid balance, initiate immune response
Transport oxygen - depleted blood
Pulmonary circuit
Describe the process of how deoxygenated blood become oxygenated.
deoxygenated blood will enter through the right atrium, go through the right ventricle, and exit out to the lungs. In the lungs, blood with attach to oxygen and enter through the left ventricle in the aorta.
Veins transfer what kind of blood?
deoxygenated
Oxygenated blood enters through the… ?
arteries
The transportation of oxygen enriched blood from the lungs occurs during?
The system circuit
CO2 exchanges ____ in lungs
oxygen
Waste products exchange ___ in viscera
nutrients
_____ carry blood AWAY from the heart
arteries
the exchange of oxygen/co2 and nutrient/waste products occur where?
capillary beds
___ carry blood back to the heart
veins
What is the lymphatic system?
the route from periphery to the venous system
List 4 functions of the lymphatic system
- collect lymph from interstitial spaces
- filter lymph
- detect and intitate response to infection
- return lymph to cardiovascular system
List 3 components of lymphatic system
- lymph capillaries
- lymph vessels
- lymph nodes
Heart failure
ventricles do not contract properly causing reduced blood flow.
heart murmur
unusual heart sounds caused by incomplete closure of valves
arteriosclerosis
hardening of arteries that causes reduced blood flow and increased blood pressure
ischemia
the lack of blood flow to an area
angina pectoris
chest pain caused by ischemia of cardiac muscle
myocardial infraction
AKA heart attack, heart cells die.
