Fetal Circulation Essay

2. The defect in Caleb’s heart allows blood to mix between the two ventricular chambers. Due to this defect would you expect the blood to move from left-to-right ventricle or right-to-left ventricle during systole? Explain your answer based on blood pressure and resistance in the heart and great vessels. It goes left to right during systole. The difference is normally, oxygen-poor (blue) blood returns to the right atrium from the body, travels to the right ventricle, and then is pumped into the lungs where it receives oxygen. Oxygen-rich (red) blood returns to the left atrium from the lungs, passes into the left ventricle, and then is pumped out to the body through the aorta. But when an infant has ventricular septal defect it still allows oxygen-rich (red) blood to pass from the left ventricle, through the opening in the septum, and then mix with oxygen-poor (blue) blood in the right ventricle. (ROCHESTER.EDU) but instead when systole occurs the blood gets mixed because of the septum therefore heart needs to pump harder to ensure that enough blood with oxygen reaches the body.

Brittany is a 22yo, G2 P1001, who was seen for an ultrasound evaluation and FTS. The patient states that she has a history of hypothyroidism but believes that she was tested in this pregnancy and told that her values were normal. I do not have copies of that lab work but would recommend that this be followed as her pregnancy progresses. She also reportedly has some issues with anxiety and IBS but is stable not on medication. She has a previous cesarean delivery with her last delivery but is uncertain about a VBAC. Lastly, she states that her main issue in this pregnancy is that when she wakes up in the morning after sleeping her arms and hands are numb or asleep and this did not occur in her previous pregnancy.

When society thinks about starfish, perch, chordate, and fetal pig they become extremely curious about how their bodies operate because of how they are made up. I will give a brief synopsis of all animals before going into major detail about them. According to the online website named dictionary.com, Starfish are any echinoderm of the class Asteroidea, having the body radially arranged, usually in the form of a star, with five or more rays or arms radiating from a central disk; asteroid (dictionary.com). It is known that a chordate is an animal belonging to the phylum Chordata, composed of true vertebrates and animals having a notochord (dictionary.com). According to research, a fetal pig is an animal in the phylum Chordata and class Mammalia (dictionary.com). A perch is known to be a certain kind of fish with very spiny fins (dictionary). Starfish, perch, chordate, and fetal pig are some very interesting animals that possess some exclusive qualities both similar and different.

Patent Ductus Arteriosus (PDA) is one of the common congenital left to right cardiac defects seen in children. The ductus arteriosus is a large communication pathway that is naturally patent in the fetus, connecting the trunk of the major pulmonary artery to the descending aorta (Shinde, Basantwani, & Tendolkar, 2016). During the fetal life, ductus arteriosus is a normal structure that allows the blood to pass from the right ventricle to the descending aorta by bypassing the pulmonary circulation. The ductus arteriosus is an important structure in the fetal development as it allow the blood flow to the rest of the fetal organ and structure. In fetus pulmonary

Soylent Green is a grim fictional ,at the time futuristic, outlook on how disregard for important environmental issues would lead to overpopulation, food shortages, climate change, and cannibalistic food alternatives. But looking into the future Soylent Green doesn't necessarily look like a work of fiction, the over population, climate change, and food shortages in the film is just a true story that hasn't happened yet.

Researchers believe that several environmental and genetic factors work together and play a role in the development of Sirenomelia. The most popular medical theory suggests that Sirenomelia could be caused by abnormalities in the blood circulating system within the embryo at an early stage of development. Some affected individuals have been found to have a single large artery followed by the absence of the usual two arteries that branch out to lower areas and carry blood to the tail end of the embryo. The single artery that is present, which is referred to as a “steal” vessel due to the fact that it essentially steals blood and nutrients from the lower part of the body, diverts the flow of blood that normally circulates from the aorta to the lower portion of the embryo back up to the placenta instead so the blood and nutrients that are needed never end up reaching the tail end of the embryo. Due to the malnutrition from this lack of blood flow, the fetus fails to develop two separate limbs. (National Organization for Rare Disorders, 2018) There is still much to learn about what causes Sirenomelia since there is so little known about it currently. When experimenting with

Working with newborns and premature babies can be a stressful job. A neonatologist mainly focuses on high-risk cases where babies cannot be delivered without complications, such as heart and lung failure, and many other birth defects. This career is a dexterous job, so it requires a lot of patience and skill. It is expected to grow over the next 10 years, as the medical field is always in need of doctors and surgeons. A neonatologist is a great career for people who like the medical field, enjoy working with others, and have a big heart to care for infants and their families.

The different between the different routes is that the fatal circulation is a circulation of blood that passes through the body of the fetus and to and from the placenta through the umbilical cord. The Portal circulation is a general term of denoting the circulation of blood through a larger vessel from the capillaries of one organ to those of another that also applied especially to the passage of blood from the gastrointestinal tract, pancreas, and the spleen through the portal vein to the liver. The Systemic circulation is the flow of blood from the left ventricle through the aorta, carrying oxygen and nutrient material to all the tissues of the body, and returning through the superior and inferior venae cavae to the right atrium.

It is considered to account for the most deaths during the first week of an infant’s life who suffers from a congenital heart defect (Texas Heart Institute, 2014). In a healthy heart, oxygen-poor blood returns to the heart from the body. The heart receives the blood through the veins and enters the right atrium where it then pushes the blood through the tricuspid valve into the right ventricle. From here, the blood moves through the pulmonary valve out of the heart via the pulmonary artery and into the lungs where it receives oxygen to be transported. The blood returns to the heart by the pulmonary veins into the left atrium where it is then passed through the mitral valve into the left ventricle. Oxygen-rich blood is pumped from the left ventricle into the aorta through the aorta valve where it is then sent throughout the body, returning to the right atrium to continue the cycle (American Heart Association,

Human tissue has played a major role in medical research and the development of vaccines for decades. Since the early 1900s, many scientists work has been helped by human tissue and the advancements that have been made using it. The development of immortal cells made it more straightforward for scientists to develop and test vaccines. But cell lines raised the issues of consent and whether or not tissues belong to the person they were taken from. The course of medical research and science changed greatly over the past century.

Did you know that when the heart contracts, blood pumps into the arteries? The fallopian tube is also called oviduct, or uterine tube. The fallopian tube is a pair of tubes along which eggs travel from the ovaries to the uterus and the blood vessels are the arteries which carry the blood away from the heart. Well, this is what my project is based on.

In my opinion I think marijuana should be legalized across the country because it does benefit a lot of people with autoimmune problems, anything that weakens the immune system, cancer, M.S., and more. Doctor’s believe that the prohibition of marijuana causes the public more harm than good. Those are some of the pros. Some of the cons of legalizing marijuana is it has an addictive nature, it can alter a user 's perception, is popularly known as a gateway drug, does damage to the brain, and more.
