Cardiovascular system Flashcards
a fluid-filled network of tubes (or vessels)
cardiovascular system
2 functions of cardiovascular system
transportation and removel/excretion
functions of cardiovascular system
what does cardiovascular system transport
oxygen gas (02), glucose, hormones
functions of cardiovascular system
what does cardiovascular system removexcert
carbon dioxide (co2) and urea
which are removed from cells
3 main parts ofcardiovascular system
heart, blood, blood vessels
muscular organ behind ribcage and between lungs, which is slightly tilted to left and the size of a clenched fist
heart
parts of heart
wall of tissue that divides left and right side of heart
septum
parts of heart
prevents blood from flowing betweeen atriums and venticles
septum
parts of heart
right and left atrium
right and left ventricle
chambers
parts of heart
triccuspid, bicuspid, aortic, pulmonary valves
heart valves
“river of life” and fluid tissue
blood
transportation of dissolved gases, nutrients, hormones, and metabolic wastes
blood
protection against toxins, pathogens, and blood loss injuries
blood
parts of blood
pale, yellowish liquid
plasma (55%)
parts of blood
92% water, 8% dissolved mixture
plasma
parts of blood
rbc, wbc, platelets
formed elements (45%)
parts of blood
erythrocrytes
red blood cells (rbc)
parts of blood
biconcave in shape
red blood cells (rbc)
parts of blood
responsible for carrying ocygen throughout the body andremoval of carbon dioxide
red blood cells (rbc)
parts of blood
anucleated/no mitochondria
means- cell wouldn’t have necessary energy to live, lacking cell nucleus
red blood cells (rbc)
parts of blood
lifespan: 120 days
rbc
parts of blood
contains hemoglobin (red chemical pigment)
rbc
parts of blood
leukocytes
white blood cells (wbc)
parts of blood
protects body from diseases caused by bacteria, viruses, and foreign substances
wbc
parts of blood
colorless and no hemoglobin, lifespan-: 11-20 days
wbc
parts of blood
larger than rbc, but fewer in number
wbc
parts of blood
thrombocytes
platelets
parts of blood
for blood clotting or coagulation, aids in wound healing prccess
platelets
highways for your blood, are the tubes that carry blood all around your body
blood vessels
parts of blood vessels
move blood away from heart
arteries
parts of blood vessels
move blood towards heart
veins
parts of blood vessels
smallest part, allows nutrients and gases to diffuse between capillary walls and body cells
capillaries
oxygenated or deoxygenated blood
high oxygen concentration, bright red in color
oxygenated blood
oxygenated or deoxygenated blood
high carbon dioxide concentration, dark red in color
deoxygenated blood
3 types of circulation
circulation of blood within heart
coronary
3 types of circulation
circulation of blood within heart and lungs
pulmonary
3 types of circulation
circulation of blood within heart and cells of body
systemic
what circulation
heart - lungs - heart
pulmonary circulation
what circulation
right side of heart, pumps deoxygenated blood to lungs
pulmonary circulation
what is the pulmonary circulation?
right ventricle - pulmonary arteries - lung capillaries - lungs *- pulmonary veins - left atrium *
bold- deoxygenated blood ; itallics- oxygenated bloood
what is the systemic circulation?
*left venticle - aorta - smaller arteries - body organs and tissues * - superior and inferior vena cava - right atrium
bold- deoxygenated blood ; itallics- oxygenated bloood
inability of blood to reach coronary arteried
coronary heart disease
due to aging or atherosclerosis - arterial wall thickens and hardens
coronary heart disease
aka hypertension - due to tightening of arterioles
hypertensive heart disease
causes the heart to work harder than normal to force blood through tightened blood vessels
hypertensive heart disease
arterial disease related with cholesterol build up inside arterial wall
atherosclerosis
results arteries to harden, loose its elasticity, and degenerate
atherosclerosis
disorder that results from blockage and hardening of arteries in the brain or neck
stroke
common to people with atherosclerosis and hypertension
stroke
inability of blood to clot properly - consistent bleeding occurs
hemophilia
due to lack of one of the plasma proteins associated with clotting
hemophilia
genetically inherited and males are mostly affected
hemophilia
condition where the rbc count stays low
anemia
due to low hemoglobin level, deficiencies and diseases,
anemia
conditions where wbc stays high, dangerous blood disorder
leukemia
