Circulatory system

• Arteries have thick, elastic walls that allow them to withstand the high pressure of blood pumped from the heart.
• The other term for circulatory system is cardiovascular system
• Pulmonary circulation is the blood transport between the heart and lungs
• Systematic circulation is blood transport between the heart and all the other parts of the body
• The heart pumps blood
• Blood vessels are tubes that carries and moves blood all around the body.
• There are 2 types of blood vessels
• Veins carry deoxygenated blood
• Arteries carry oxygenated blood
• Hepatic blood vessels return low-oxygenated blood from your liver back to the heart
• Renal blood vessels carry blood from the kidney and ureter to the inferior vena cova
• The inferior vena cava is a large vein that carries blood to the heart from the lower part of the body
• The right side of the system takes care of the deoxygenated blood
• The left side of the system takes care of the oxygenated blood
• Valves regulates blood flow
• The left ventricle has a thicker wall and pumps blood with higher pressure than the right ventricle. This activity pumps blood to the whole body compared to the right ventricle that only pumps blood to the lungs
• The valves prevent the backflow of blood
• The heart's right atrium receives deoxygenated blood from the body through the superior/inferior vena cava
• The deoxygenated blood moves to the right ventricle and goes to the triscupid valve
• From the triscupid valve the deoxygenated blood then goes to the right ventricle
• From the right ventricle the deoxygenated blood then goes to the pulmonary valve to the pulmonary artery then to the lungs to become oxygenated blood
• After it becomes oxygenated blood it goes to the pulmonary vein and goes down to the left atrium and then the mitral valve and then the left ventricle and goes through the aortic valve and exits through the aorta
