Human functioning comprises many intricate systems. For example, the nervous system has numerous types of signaling systems providing communication between the brain and the body. Neurotransmitters are part of this complex signaling system and function as chemical messengers that facilitate the transfer of information from one neuron to another by way of chemical transmission, or via Synaptic Transmission. The right combination of neurotransmitters is necessary for all fluids, cells and organs in the human body to work together and achieve balance (homeostasis).

Metabolic syndrome refers to a combination of various medical conditions which increase one’s risk of developing cardiovascular disease, type 2 diabetes and other long-term medical conditions. Rather than being one single condition, a metabolic abnormality is actually a collection of metabolic changes in the body which take place at the same time. Learning about the biology behind metabolic syndrome will help us learn how these metabolic conditions are related to our lifestyle, hormone activity and the functioning processes within our bodies and can affect overall health.

Your family’s health history (and the way it has affected their health) can help determine your risk of developing many health conditions. Your family history includes many health issues due to the fact that people are often genetically similar to their family members and also have a similar lifestyle and environment.

The leading cause of illness and death throughout the world are Cardiovascular Disease. In many cases, Cardiovascular Diseases develop slowly over a period of years, with little or no symptoms until late in the disease process when symptoms appear. By this time, the disease has caused significant damage to the heart. The goal of Preventive Cardiology is to find the problem early and take steps to prevent more serious problems, such as heart attacks and heart failure, from occurring. Cardiac MRI is one of the most effective ways to do this.

The CBC blood test is the most common way to routinely prescribe a blood test in a doctor’s office and provides valuable information about the different kinds of cells in blood, which can help physicians assess a patient’s general health. Since a number of health conditions can affect blood cells, CBCs are frequently the first step to diagnosing a health condition when symptoms are unclear or monitoring an ongoing health issue.

Lung disease, especially lung cancer, generally grows very quietly without major symptoms until later stages. During the early stage of lung cancer, symptoms may not exist, may be vague or may be so mild they go unnoticed. By the time someone starts having more obvious symptoms of lung cancer (such as a prolonged cough, chest discomfort/pain and/or difficulty breathing), the disease is usually in a much worse state than if it were caught earlier when it was a lot easier to treat.
