Echocardiography (echo) can be used to evaluate your cardiac performance, the function of your heart valves, the thickness and motion of your heart walls, and the size of your heart chambers. An echo can help diagnose many heart conditions. Cardiac performance An echocardiogram can show how well your heart pumps blood (cardiac performance). To evaluate…

The respiratory system is responsible for supplying our bodies with oxygen. This is done through respirations. There are two different respirations the external and the internal. The external respiration is the exchange of air between the lungs. This happens when oxygen is inhaled into the sacs of the lungs. Precisely at that time passes into…

Many people believed that the bone is static and inert, but this idea is incorrect, the organic andmineral components of the bone matrix are continually being recycled and renewed through aprocess called remodeling. This process goes under way throughout life, as part of normal bonemaintenance. Bone remodeling plays a key factor between the activities of…

Empyema is a disease causing pus and fluid, from the infected tissue, to collect in a body cavity. The word Empyema is derived from the Greek word empyein, which means pus-producing (suppurate). Empyema is commonly used to refer to pus collection around the lung (pleural cavity), known as Empyema Thoracic. However, similar collection can also…

Several principles govern metabolic pathways in the cell: Complex chemical transformations in the cell do not occur in a single reaction, but in a number of small steps that are connected in a pathway. Each reaction is catalyzed by a specific enzyme. Metabolic pathways is catalyzed by a specific enzyme. Many metabolic pathways are compartmentalized,…

Basal Metabolic Rate has been defined as the minimum amount of energy needed by an animal to maintain the basic functions of survival (such as breathing). Several factors including age, gender, weight, and exercise affect the BMR. “BMR increases with increasing muscle tissue” therefore, exercising will enhance BMR while with increasing age, BMR is reduced…

Cell distinction is the procedure that takes topographic point inside an embryo that determines which cistrons are expressed and therefore, what type of cell it will fall back. This means that the cell can execute a specific map. There are more than 250 general types of cells in the human organic structure.In workss and animate…

Neurotransmitters.             Neurotransmitters refer to certain chemicals agents which relay, modify and modulate signals from the neurons to other cells in the body (Rang, 2003).  When these chemicals are secreted at terminal axon ends of the nerve cells, they diffuse across the synaptic gap thereby transmitting information to the nearby adjoining cells such as glands,…
