Circulatory system

• Right Atrium receives deoxygenated blood from the body through the superior vena cava, inferior vena cava, and coronary sinus
• Pulmonary veins are the blood vessels that carry oxygenated blood from the lungs to the left atrium.
• Left Ventricle pumps oxygen-rich blood out into the arteries of the body
• The right atrioventricular valve (tricuspid) separates the right atrium from the right ventricle.
• The left atrium receives oxygen-rich blood from the lungs via the pulmonary veins.
• The left atrioventricular valve (bicuspid or mitral) separates the left atrium from the left ventricle.
• The right ventricle pumps blood into the pulmonary artery which carries it to the lungs where carbon dioxide is removed and oxygen is added to the blood.
• Blood pressure refers to the force exerted by blood against the walls of blood vessels as it flows through them.
• The left ventricle pumps blood out of the heart via the aorta to all parts of the body except the lungs.
• The right ventricle is responsible for pumping deoxygenated blood to the pulmonary trunk (pulmonary artery)
• The heart is divided into four chambers by two sets of valves - the tricuspid valve between the right atrium and ventricle, and the bicuspid valve between the left atrium and ventricle.
• The PH of blood is 7.35-7.45
• Arteries carry blood away from the heart
• Veins return blood back to the heart
• Capillaries are tiny tubes that connect arteries with veins
• Blood has 4 components; White and Red Blood Cells, Platelets, and Plasma.
• Red blood cells transport oxygen around the body
• White blood cells fight infection
• Plasma is the liquid part of blood which carries nutrients, hormones, waste products, and gases such as carbon dioxide and oxygen
• The circulatory system consists of the heart, blood vessels (arteries, capillaries, and veins), and blood
• Platelets clot blood when we cut ourselves
• Blood types are determined by the presence or absence of antigens on the surface of red blood cells.
• Type A has only type A antigen
• Type AB has both type A and type B antigens
• Type O has neither type A nor type B antigens
• Type B has only type B antigen
• A person's own antibodies will attack foreign antigens if they receive a transfusion with mismatched blood.
• Pacemakers are found in the right atrium of the heart and are responsible for the normal rhythm of the heart
• Three major types of blood vessels are; Arteries, Veins, and capillaries.
• Capillaries connect arteries and veins and allow exchange between cells and blood.
