A neonatologist is a doctor that specializes in the field of neonatology. So... "Neonatologist" is basically a fancy technical term for "baby doctor." Marfan Syndrome Marfan syndrome and related disorders affect the body’s connective tissue. Connective tissue holds the body together and plays a role in its growth and development. This disorder can affect many parts of the body since connective tissue is found all over the body. Bones, joints, eye, skin, lungs, the heart and blood vessels are…

By taking Lasix, it is categorized as diuretic. The medication works by elevating the amount of water and salt in the blood which removes by the kidney. The adrenals are two small glands which sits on the top of the kidneys secrete important hormone, aldosterone. Aldosterone regulates the water level, but the water is extremely lost by taking Lasik; therefore, it cannot help body to recover hydrate. Lasik caused the decrease in blood volume causing dehydration. The blood pressure is affected due…

Pathophysiology behind Coronary Artery Disease Coronary artery disease also known as CAD is a condition where there is a build up on the inside lining of the artery usually composed of cholesterol or plaques. This can cause the narrowing of the coronary artery lumen, which can then reduce the volume of blood that pass through them. The lack of poor blood flow can lead to myocardial ischemia, which is a lack of blood flow to the heart and it can lead to heart tissue death. Another condition…

Method A relaxed subject breathed into a clean mouthpiece for a period of 1-2 minutes with an oximeter placed on the tip of the index finger. During this time, the subject was asked to stay still with their hands in their lap and palms pointing upwards as well as wearing a nose clip. This normal breathing was recorded on the computer and then the volunteer was asked to exhale for 4-6 seconds after a normal inspiration to ensure the collection of an end tidal volume sample. The recording was…

blood clots to prevent excess blood loss, carrying cells and antibodies that fight infection, bringing waste products to the kidneys and liver, which filter and clean the blood, and regulating body temperature. The blood that runs through the veins, arteries, and capillaries is known as whole blood, a mixture of about 55 percent plasma and 45 percent blood cells. About 7 to 8 percent of your total body weight is blood. An average-sized man has about…

Over the years, biologists have carried out experiments to explore the differences in animal hearts. With regards to this experiment at hand, the differences were explored between mammalian and amphibian hearts. This experiment also helps us determine the effects of external, biological factors and pharmacological substances on the contraction of the heart. The following will serve as an overview of the structure and functioning of amphibian heart. A frog heart has three chambers (two atria and…

Breathing air in and out is the first step to the respiration process. Respiration is a series of metabolic reactions and processes that take place within the cells of organisms. The organisms store biochemical energy within adenosine triphosphate (ATP) molecules. For the process to being, we must first draw air into our lungs. The lungs muscles contract and expand the chest cavity, causing a negative or hypotonic pressure within the pleural cavity. The hypotonic pressure then forces the lungs…

Humans and other mammals have a Diving Response, which can be also known as ‘The Mammalian Dive Response/Reflex. The Diving reflex consists of set of reflexes that are activated when our face is cooled or if we hold our breath. This is a clever psychological mechanism because it enables our bodies to manage and to tolerate a lower level of oxygen in an environment that we do not normally face every day. There are three main changes that occur in our body when our Dive reflex triggers;…

dizziness, and Adams-stokes syndrome. "Adams-stokes syndrome is a condition of fainting spells caused by heart block, often AV block, and can lead to bradycardia, slow heart rate, and a decrease in cardiac output" (Umassmededu, 2016). Third degree heart block has the most severe symptoms of all witch include dizziness, fatigue, fainting, shortness of breath, and chest pain. Treatment The treatment of heart block can vary depending on the severity and cause of the condition. If heart block in…

In general, pediatric epilepsy consists of transient cardiac events. Adult seizures, particularly those with underlying cardiovascular conditions, pose risk to the cardiovascular system, including cardiac ischemia. Respiratory changes are possible across the lifespan, from infants to older adults. Cardiac function seems to be dependent upon the type of seizure occurring. The majority of complex partial, tonic-clonic and temporal lobe seizures are associated with increased heart rate. This…
