A study published in the Journal of Bone and Mineral Research shows that there is a 30 per cent increase in the risk of fractures after a gastric bypass operation. The study also discovered that falls increase after these operations as well. “Gastric bypass is a well-established method that has proven effective in reducing obesity, diabetes and mortality, so naturally our findings do not mean … Continue reading News Digest |Study finds Gastric Bypass increases risk of Bone Fractures and falls

There are four main components of the conducting system of the heart, these are the SA node, AV node, the bundle branches and the Purkinje fibres. Also, we have subcomponents called the tracts and branches, each of these components have specialised cells that are able to conduct electrical impulses. Sinoatrial Node ( SA node) This is the first primary pacemaker of the heart and … Continue reading The Cardiac Conduction System
The three physiological functions that are responsible for adequate tissue and cellular oxygenation are: Pulmonary gas exchange Oxygen delivery Oxygen consumption The respiratory system helps gas exchange through the process of ventilation, diffusion and perfusion for the uptake of oxygen and helps with the removal of carbon dioxide from the body. Functionally the respiratory system consists of the functional zones and the conducting zones, namely … Continue reading The Explainer | How does the Body Controls Breathing?
The Male reproductive system has four regions – gonads duct system, accessory glands and the penis. The gonads are the testes, this is the site for sperm formation (spermatogenesis). The testis is located outside the body in the scrotum. Embryological the testes develop within the abdomen and usually descend about seven months during the foetal development and if they do not descend a condition called … Continue reading Homer Simpson’s Guide to The Male Reproductive System
MITOSIS Growth and repair, the cells in adults that don’t undergo mitosis are NEURONS and the sperms and the ova. Most of the time the cells are in interphase where DNA is uncoiled and is known as chromatin. Mitosis and meiosis are a continuous process Two daughter cells that are identical The first stage of MITOSIS is the duplication of the DNA genetic material, and … Continue reading STAGES OF MITOSIS AND MIOSIS
