It’s just something they all do. Arguably, some are less fussy than others, but the fact remains that it’s impossible to find a baby who will not cry at some point. Crying is a sign that a baby is alive when he or she is born. This process allows for air to enter their lungs for the first time in their lives. From birth onwards, babies quickly learn to use their cry as a primary communication tool in the outside world.
The heart forces the ‘oxygenated’ blood through a range of connecting blood vessels specifically speaking arteries which travel around your body providing your cells with the necessary materials that the blood contains. As the blood reaches your cells the oxygen is released in order for the cells to function. The cells then give out waste materials which can include co2 and water. In order for your blood to receive these waste products they absorb it. We now have deoxygenated blood which goes through your veins aiming towards your heart.
Describe the 3 main types of blood circulation? - https://www.reference.com/science/three-types-circulation-28f4fb9363b09f33 The three types main types of blood circulation are 1 - Systemic circulation 2 – Pulmonary circulation 3 – Portal circulation These three systems work together for the proper oxygenation and blood flow throughout the body. Systemic Circulation is when the network of vessels carry blood from the heart to the body and from the body back to the heart Pulmonary Circulation is a network of vessels that carries blood to and from the lungs Portal Circulation is the network of arteries and veins that supplies blood to all the cells of the heart Describe the cardiac cycle and blood pressure Ref -
In most of the cases, women pay attention to doctor’s recommendations, they also can notice the non-verbal signs . Truog (1996) consider that “an informed choice can be made if women receive all the information relevant to the decision to undergo or forgo the test and feel free of coercion or persuasion” . The decision to give birth to a child, who have disabilities is depends on socio-economic status of family. It is especially difficult for the families with unsufficient economic and emotional status. However, even families with high income may have difficulties with such decision due to fraud of society opinion .
Underlying theory: • Circulatory system theory: It is the body’s main transport system, the system is made up of the heart, the blood and the blood vessels. The blood transports oxygen, carbon dioxide, hormones and nutrients, . The circulatory system is a closed system which means that blood flows around the body enclosed in blood vessels and does not leave the blood vessels. The heart: The heart consists of many layers: 1. The pericardium- It has two layers.
It partakes in directing the volume and organization of liquid encompassing the cerebrum through particular transport procedures, and hence adds to homoeostasis of the focal sensory system (Peterson, 2012). The blood-brain barrier is a mechanism that controls the passage of substances from the blood into the brain. It lets essential metabolites, such as oxygen and glucose, pass from the blood to the brain and central nervous system. It is a cellular and metabolic barrier located at the capillaries in the brain that alters permeability, restricting the passage of some chemical substances from the bloodstream into the neural tissue, while allowing other substances to pass into the
Since blood needs to circulate through the heart in a one-way system, special flaps, which are called valves, prevent blood from flowing back in the incorrect way (Ballard, 7). As the right side of the heart pumps oxygen-deprived blood along the pulmonary arteries to the lungs, blood loses carbon dioxide and collects oxygen in the lungs (Rogers, 66). "The pulmonary veins open into the left atrium of the heart," recalls Rogers (66). This is pulmonary circulation. When the left side of the heart pumps blood along the aorta and around every part of the body, it takes oxygen to the tissues where it is needed and collects nutrients and waste products (Rogers, 67).
Problem: Nowadays, one problem that science has solved is the way to minimize the chances of disability and keep multiple birth to an ideal number during the period when the babies were still embryos. To solve this problem, one process has been developed and commonly used all around the world: Selective abortion. Solution: Selective abortion became a process to help the families who had in-vitro fertilization to have the children with the best characteristics as possible and the number of children they want. It allows these families to select dominant genes, get rid of possible disability in earlier times of pregnancy and (in some cases), choose the gender of the baby as they want at the same time. In-vitro fertilization is a process of putting
Gene therapy is a way to fix a way to fix genetic problems at its origin. When adding a correct copy of the gene without the disease, to the gene with the disease it can recreate the infected tissues and organs in order to work properly again. This technique is a lot better than the traditional medication as it not only heals the symptoms but also the actual problem. To solve the problem, gene therapy uses a vector, this is usually a virus, which delivers the message to rebuild the protein molecules and ribonucleic acid. However, it cannot cure all the diseases (Gene therapy).
While advantages of plateletpheresis : are exposure to single donor rather than multiple , so it can easily doing tests for donor and recipient such as HLA type and blood typing . and because platelets separated automatically during donation and usually transfused on same day ,platelets last longer and thus less platelets need to be given to the patient. also repeat the procedure after 72 hour if possible ,and decrease the chance of allo immunization and transfusion transmitted disease .while the disadvantage is , For a unit of apheresis Platelets hospitals paid an average of $535.15 (Bi, 2011)because plateletpheresis is expansive as it involves using a very skillful machine .and time consuming about 2 hours. (KWleong) Bothe pooled platelets and plateletpheresis contain WBC that may cause febrile non hemolytic transfusion reaction and other problems , so leukocyte are reduced before(as filter in Apheresis ) or after storage but not at bedside , to reduce the problems that may lead to platelets
Being able to clone may allow the cause of different diseases to be found. Diseases have a major impact on a lot of people 's cause of death. Cloning could allow you to find the causes; why wouldn 't you want to find the cause of a disease. "Researchers hope to use embryonic stem cells, which have the unique ability to generate virtually all types of cells in an organism, to grow healthy tissues in the laboratory that can be used replace injured or diseased tissues ("Cloning fact sheet"). Recreating a human could conflict with religion.
I do believe parents should be able to pick genetic characteristics of their children, only if it is absolutely necessary and the parents want to have their own child. Some of the pros to this might be that the parents have a high chance of a genetic disease, so a designer baby might be necessary to reduce or remove that genetic disease. I feel that designer babies should only be designed if it is some genetic disease or something that would harm the baby only to eliminate the disease. Designer babies can prevent genetic disorders, which can create a healthier generation of kids in the future. Therefore this can eliminate genetic diseases for everyone and make future reproduction easier by not having to use designer babies again.
Stem cells are unspecialized cells that are capable of renewing themselves through cell division (Stem Cell Basics I). This allows stem cells to be reprogrammed and regenerated which offers new potentials for transplants to treat various diseases such as diabetes or heart disease. The stem cell process is specific and has to be followed correctly in order to ensure success. During the stem cell process the patient receives a high-dose of chemotherapy, which is then followed by the stem cell transplant (Stem Cell Transplant). This allows the newly inserted healthy stem cells to grow and replace/repair the previous diseased cells.
Embryonic stem cells are the cells which potentially provide life to a blastocyst and lead to the creation of a fetus, or baby. Recently there have been many experiments conducted to extract embryonic stem cells from the blastocyst. With this new research, has also come a huge controversy. Although embryonic stem cell research is practiced with good intents and is designed to find cures for people already suffering or living a limited lifestyle due to health disabilities, what is not always mentioned is that another human’s life is being destroyed in the process. These innocent babies, whether it be considered legal or not, are being plucked from their mother’s womb to be used for nothing more than a science experiment.
In most situations, prenatal testing will assure the parents that their baby is developing normally. Although if a disease is detected while a woman is still pregnant, this allows for procedures to be prepared ahead of time. Also it allows for the parents of the baby to prepare themselves emotionally and to properly arrange the home environment to accommodate for a child with special needs. Prenatal genetic screening can not determine for sure if a condition will be present but can show if the fetus is at a high or low risk. The goal for people who are for genetic screening is to no longer see genetic disorders exist within children.
