When Neurons communicate with each other at intersections called synapse function. In the synapse, one neuron sends a message to the target neuron – another cell. Most synapses are chemical, these synapses communicate using chemical transmitters. Other synapses are electric, in these synapses, ions flow directly between the cells. In a chemical synapse, action […]
The endocrine system functions consist of hormone-producing and secreting glands. The chemicals produced in the body that regulate the activity of cells or organs. These hormones regulate body growth, metabolism (physical and chemical processes of the body) and sexual development and function. Hormones released into the bloodstream and can affect one or several organs throughout […]

The smooth endoplasmic or smooth ER reticulum is an organelle that occurs both in animal cells and in plant cells. The organelle is a subunit in a cell that has a specialized function. The main function of a smooth ER is the production of cellular products such as hormones and lipids. It also distributes these […]
A study by a food regulatory authority showed that seven out of ten hens sold in British supermarkets are contaminated with a dangerous bacterium that causes food poisoning. Every year, 280,000 people get sick and kill 100 people. Chicken is the most common cause of food poisoning in the UK, so the Food Standards Agency […]
The SA node, also known as the sinus node. It is a group of cells located in the wall of the right atrium of the heart. These cells have the ability to spontaneously produce an electrical impulse (action potential, see below for more details) that travels through the heart via the electrical conduction system, causing […]
Lymph is a fluid that flows through the lymphatic system, a system composed of lymphatic vessels (channels) and intervening lymph nodes, whose function, as the venous system, is the return of fluid from tissues to the central circulation. Interstitial fluid between cells in all body tissues enters the lymphatic capillaries. This lymph fluid is then […]
Lymph nodes (mediastinum) are small round organs of the lymphatic system that support the proper functioning of the immune system. They help the body fight infection by filtering foreign lymphatic particles, a transparent or whitish fluid that consists of white blood cells. Lymphrate also contains a type of white blood cells called lymphocytes that help […]
The Bulbourethral gland, also known as the Cowper gland for the English anatomy of William Cowper, is one of the two small exocrine glands in the reproductive system of many male mammals (all domesticated animals that are not only found in a dog). They are homologous to Bartholin’s glands in women. Bulbourethral gland function […]
