What does the cardiovascular system consist of? |
-Heart -Blood Vessels |
|
|
Arteries |
•moves fluids away from the heart -oxygenated |
|
|
Capillaries (microscopic) |
•intermediary bw arteries and veins |
|
|
Veins |
•move fluids away from the heart |
|
|
What are the blood vessel types ? |
1.arteries 2.capillaries 3.veins |
|
|
What are the functions of the cardiovascular system? |
To transport: 1.nutrients 2.waste 3.homeostasis |
|
|
Coronary arteries |
Supply oxygen and nutrients to heart tissues -1st to branch off from aorta |
|
|
Pulse |
•the expansion of arteries as blood passes through by relaxation *heart rate =pulse* |
|
|
Blood pressure |
The pressure of blood against the wall of a blood vessel -sphygmomanometer -systole & diastole (why we have 2#s for blood pressure) |
|
|
Severe combined immunodeficiency (SCID) |
Typically a genetic condition when a person' a WBCs don't produce an enzyme needed to allow B and T cells to develop |
|
|
Leukemia |
A cancer derived from WBCs division out of control |
|
|
Infectious mononucleosis |
Epstein-Barr virus (EBV) infects lymphocytes which which initially result in a sore throat and swollen throat and swollen lymph nope |
|
|
Pre-capillary spincter |
A ring of muscle that controls blood flow |
|
|
Arteriovenous shunt |
Direct portal from an arteriole to a vein w/o using capillaries |
|
|
How does the blood flow? |
From the : Heart>Arteries >arterioles> capillaries> venules >veins > heart |
|
|
Law of thermodynamics |
1st lot: matter and energy cannot be made or destroyed,only transformed 2nd lot: all matter /energy move to greater disordered states (matter moves from greater concentration to lower concentration) |
|
|
Sinoatrial node(SA) |
Upper dorsal wall of the right |
|
|
Atrioventricular node |
Base of the right atrium ,near the septum |
|
|
Aneurysm |
Burst of blood vessels -due to blood clot |
|
|
Hypertension |
High blood pressure |
|
|
Atherosclerosis |
Formation of lensions (plaques) on the side of a blood vessel -results in narrow vessels |
|
|
Thromboembolism |
Clot carried to a capillary bed and can result in dangerous condition |
|
|
Stroke (Cerebrovascular accident(cvs)) |
When a small cranial arteriole burst/blocked by an embolus |
|
|
Heart attack (myocardial infraction,MI) |
When part of the heart dies due to a lack of oxygen |
|
|
Angina pectoris |
When a coronary artery becomes obstructed -feel tightness in chest (chest pain ) |
|
|
Jaundice |
Condition where the liver fails to excrete heme resulting in a yellowing of the skin and eyes |
|
|
Anemia |
A condition where there are few RBCs or the RBC don't have enough hemoglobin resulting in a fatigue-like feeling -iron or B12 deficiency |
|
|
Sickle cell anemia |
Genetic condition resulting In the sometimes destruction of RBCs |
