Cardiovascular system
B2.5 The role of the components in performing the functions of the cardiovascular system:
• components of the cardiovascular system:
o mammalian heart:
▪ atria, ventricles, aorta, vena cava, pulmonary artery, pulmonary vein, tricuspid valve,
pulmonary valve, mitral value and aortic valve
o arteries
o veins
o capillaries
o blood made up of plasma, platelets, erythrocyte and leukocytes
• the function of the components of the cardiovascular system:
o the path blood would take around the human cardiovascular system
B2.6 The process of the cardiac cycle:
• the electrical activity of the heart (for example, PQRST waves) and how heart rate is controlled and
regulated
• pressure changes in the heart and blood vessels and how this is linked to blood pressure
B2.7 The development, impact and management of coronary heart disease (CHD):
• causes of the disease
• impact on systems within the body and on physical and mental health
• how common treatments relieve symptoms:
o blood thinning medicines
o statins
o betablockers
o lifestyle changes to promote self-care and better health
