Recommended: Relationship between the respiratory and cardiovascular system

When a baby is born, the first breathes are taken and the lungs begin to expand. As the lungs expand, the lungs are cleared of fluid. There is an increase in the baby's blood pressure and a significant decrease in the pulmonary pressures. This reduces the need for the body to shunt blood. These changes promote the closure of the shunt. These changes increase the pressure in the left atrium of the heart, which also decreases the pressure in the right atrium. The shift in pressure promotes the foramen ovale to close.
The process for an adult’s circulation system starts with non-oxygenated blood entering the right atrium from the inferior and superior vena cava. Once in the right atrium the tricuspid valve opens and drains the blood to the right

  • Mitral Valve Prolapse

    872 Words  | 2 Pages

    The normal Mitral Valve controls blood flow between the upper (left atrium) and lower chamber (left ventricle) of the left side of the heart. The mitral valve allows blood to flow from the left atrium into the left ventricle, but not flow the other way. With each heartbeat, the atria contract and push blood into the ventricles. The flaps of the mitral and tricuspid valves open to let blood through. Then, the ventricles contract to pump the blood out of the heart. The flaps of the mitral and tricuspid valves close and form a tight seal that prevents blood from flowing back into the atria (nhlbi.nih.gov).

  • Hypoplastic Left Heart Syndrome Essay

    2105 Words  | 5 Pages

    During pregnancy an echocardiogram of the fetus can be done to produce images of the heart by sending ultrasonic sound waves to the vital organ. These sound waves create an image for the physician to analyze the babies heart function, structure sizes, and blood flow. A positive diagnosis before birth has shown to improve chances of survival, and will allow for appropriate care to be readily available at birth. If a baby is born without being diagnosed with the heart defect, some symptoms previous noted such as low oxygen levels can be suggestive of hypoplastic left heart syndrome. The baby may not display any symptoms or signs for hours after birth because of the openings allowing for blood to be pumped to the rest of the body. However, listening to the babies heart can revel a murmur indicating an irregular flow of blood in the heart. If a murmur is heard, or signs of the defect are observed, diagnostic tests will be ordered and performed. An echocardiogram is still the go-to test once the baby is born to evaluate the heart. The echocardiogram will diagnose the newborn, by revealing the underdeveloped left ventricle, mitral and aortic valve, and the ascending aorta commonly seen in

  • Patent Ductus Arteriosus ( Pda )

    1437 Words  | 3 Pages

    According to Batshaw, Roizen, and Lotrecchiano (2013), patent ductus arteriosus (PDA) is “the persistence of a fetal passage permitting blood to bypass the lungs” (p. 745). This is an inherited heart condition in which the ductus, a small pathway between the pulmonary and the aortic, valves remain open. This cardiovascular problem usually occurs in low birth weight infants. The blood vessels usually naturally closes after birth (Batshaw et al., 2013, p. 96). It becomes atypical if it remains open after the neonatal period. The structure usually closes in typical developing newborns around the initial 24 hours, and anatomical closure is supposed to follow several weeks later (Stanford Children’s Health, 2015). At the point when the ductus arteriosus stays open, the blood from the oxygen-rich aorta blends with the oxygen-poor pulmonary artery causing the higher chance of blood pressure in the lung pathways (U. S. Department of Health and Human Services, 2011). Certain children who have patent ductus arteriosus may be given medication, relying upon the circumstance to standardize the blood and oxygen levels until surgery is performed. Doctor can treat this condition by providing pharmaceutical medicine, catheter-based procedures, and surgery (U. S. Department of Health and Human Services, 2011).

    If the foramen ovale fails to close deoxygenated blood from right atrium will mix with oxygenated blood from the left atrium and vice versa. If the ductus arteriosus fails to close, oxygenated blood from the aorta can go in to the deoxygenated blood of pulmonary artery. As a result, fluid in the lungs increases, making it harder for the baby to breathe. The baby also has an increased risk of developing an infection in the blood vessel known as bacterial endocarditis.

  • Interrelation of Circulatory and Respiratory Systems

    both these sysmtems work with one another to ensure that organs tissues in the body are supplied with an adequate amount of oxygen, and that carbon dioxide can be removed. firstly through the respiratory system, oxygen is inhaled through the nose and mouth, the oxygen is will travel down the trachea, the rachea divides into the bronchial tubes which enters the lungs. the bronchi divides into smaller branches known as the bronchioles, which have tiny air sacs called alveoli on the end. The alveoli is surrounded by thin blood capillaries, the wall of the capillaries is a single layer of cells. These thin walls allow gas exhange to take place. Oxygen will be diffused in the capillaries and will go into the red blood cells, where it will then be transported back to the heart. carbon dioxide will be diffused though the capillary walls into the alveoli, in an opposite path than oxygen. carbon dixoxide will be released in the lungs and through exhalation the carbon dioxide will be removed.The right atrium of the heart will supplied with de-oxygenated blood by the superior and inverior vena cava. The right atrium will pump the de-oxygenatd blood via the atrioventricualr valve until it reaches the right ventricle. the right ventricle will pump the de-oxygenated blood via the pulmonary semi-lunar valve, which will carry the blood pass through the pulmonary arteries unti it reaches the lungs. these veins from the lungs will carry oxygenated blood to the right atrium. the right atrium will now pump this fresh oxygenated blood past the aventricular valve so it can enter the left ventricle. the left ventricle the thickest out of the four chambers and will pump, so that oxygenated blood is supplied to all the organ tissues in the

    Our heart is encircled by blood vessels. These blood vessels are called coronary arteries. They originate in the aorta and supply the heart muscle with oxygen rich blood. Coronary arteries consist of Right Coronary Artery, that branches into Marginal RCA and Posterior Descending Artery, and Left Main Coronary Artery, which branches into Left Circumflex, Marginal LCA and Left Anterior Descending Artery.

    The heart serves as a powerful function in the human body through two main jobs. It pumps oxygen-rich blood throughout the body and “blood vessels called coronary arteries that carry oxygenated blood straight into the heart muscle” (Katzenstein and Pinã, 2). There are four chambers and valves inside the heart that “help regulate the flow of blood as it travels through the heart’s chambers and out to the lungs and body” (Katzenstein Pinã, 2). Within the heart there is the upper chamber known as the atrium (atria) and the lower chamber known as the ventricles. “The atrium receive blood from the lu...

  • Circulatory System

    The Circulatory System is a transportation and cooling system for the body. The Red Blood Cells act like billions of little mail men carrying all kinds of things that are needed by the cells, also RBC's carry oxygen and nutrients to the cells. All cells in the body require oxygen to remain alive. Also there is another kind of cells called white blood cells moving in the system. Why blood cells protect from bacteria and other things that are harmful. The Circulatory system contains vein arteries, veins are used to carry blood to the heart and arteries to carry the blood away. The blood inside veins is where most of the oxygen and nutrients are and is called deoxygenated and the color of the blood is dark red. However, blood in the arteries are also full of oxygen but is a bright red. The main components of the circulatory system are the heart, blood, and blood vessels.
