CIRCULATORY SYSTEM - Coggle Diagram
CIRCULATORY SYSTEM
HEALTH
DOUBLE CIRCULATION
SYSTEMIC LOOP
left ventricle to artoa artery
tissues
exchange nutrients and gas (capillaries)
blood with CO2 and wastes
right atria from cava veins
PULMONARY LOOP
right ventricle to pulmonar arteries
lungs
gas exchange (oxygen in co2 out)
left atria from pulmonary veins
blood disorders
anaemia
low haemoglobin´s level (low iron)
get tired easily (low energy)
balanced diet
leukaemia
cancer bone marrow
deficient production of blood cells
blocked arteries
lipids cholesterol in walls
artery dinameter reduced
astheroclerosis
in heart (coronary arteries)
myocardial infarction (heart atack)
partially blocked
angina pectoris
BLOOD
Plasma
transport nutrients wastes
mostly water
yellow liquid
Blood cells
platelets
small groups
stop bleeding (plots)
white cells
protect against infections
with nucleus
red cells
transport oxygen (haemohlobin)
no nucleus
dubly concave
BLOOD VESSELS
ARTERIES
heart to organs
high pressure
wall strong elastic
VEINS
low pressure
organs to heart
thinner walls
CAPILLARIES
very small diameter
exchange blood cells
dense networks into organs
HEART
structure
myocardium
muscle walls
2 ventricle
blood out of heart (through arteries)
2 atria
blood into heart (through veins)
hearbeat (cardiac cycle)
diastole (relaxation)
atria fill with blood from veins
second sound (artery walls closed)
ventricular contraction (systole)
blood out of heart
first sound (atrioventriicular valves closed)
atrial contraction (systole)
blood to ventricles
