circulatory system

• Arteries carry oxygenated blood away from the heart to the body.
• The heart is a muscular organ that pumps blood through the circulatory system.
• The heart has four chambers - two atria and two ventricles
• The blood is composed of plasma, red blood cells, white blood cells and platelets.
• Veins return deoxygenated blood back to the heart.
• White Blood Cells (WBC) are involved in fighting infection and disease.
• Blood enters the left atrium, then passes through the bicuspid valve into the left ventricle, where it is pumped out through the aortic semilunar valve into the aorta.
• Red Blood Cells (RBC) contain haemoglobin which binds with oxygen and transports it around the body.
• Veins return deoxygenated blood to the heart.
• Plasma carries nutrients, hormones, waste products and gases around the body.
• Platelets play an important role in clotting.
• Red Blood Cells (RBC) contain haemoglobin which carries oxygen around the body.
• Arteries carry oxygen-rich blood away from the heart.
• Arteries carry oxygenated blood away from the heart.
• Arteries carry blood away from the heart under high pressure.
• The cardiovascular system consists of the heart, blood vessels and blood.
• The right atrium receives deoxygenated blood from the vena cava.
• Capillaries are tiny blood vessels where exchange between cells takes place.
• Capillaries allow exchange between cells and plasma.
• the circulatory system delivers oxygen and nutrients into the body's cells by the blood stream.
• the main components of the circulatory system include the heart, blood vessels (arteries, veins, capillaries) and blood. They work together to transport oxygen, nutrients, hormones and waste products through the body.
