ProblemsProblems

Cardiovascular disease-plaque or fatty Cardiovascular disease-plaque or fatty deposits build up inside ateries or veins, deposits build up inside ateries or veins, closing down those vessels and blocking closing down those vessels and blocking blood from the heartblood from the heart

Anemia-not enough iron in the blood, Anemia-not enough iron in the blood, therefore blood does not carry enough therefore blood does not carry enough oxygen-easily tired and windedoxygen-easily tired and winded
