Definition: The kidney is a bean-shaped organ located in the posterior abdominal cavity. It is part of the urinary system and is primarily responsible for filtering blood to remove waste products and excess substances, maintaining fluid and electrolyte balance, and regulating blood pressure. Parts of the Kidney: Functions:

Fat-soluble vitamins are a group of vitamins that are absorbed along with fats in the diet and can be stored in the body’s fatty tissue and liver. The four fat-soluble vitamins are: Vitamin A: Essential for vision, immune function, and skin health. Found in foods like liver, carrots, and leafy green vegetables. Vitamin D: ImportantContinue reading “Vitamins”

Neuron Neurons are nerve cells. Response to stimulus is the function of Neurons. Neurons are nerve cells that send messages all over your body to allow you to do everything from breathing to talking, eating, walking, and thinking. Until recently, most neuroscientists (scientists who study the brain) thought we were born with all the neurons weContinue reading “Neuron”

What is reproduction? Reproduction is the biological process by which living organisms produce new individuals of the same species. It is a fundamental characteristic of all life forms and is essential for the continuation of a species. Reproduction serves to pass on genetic information from one generation to the next, ensuring the survival and geneticContinue reading “Reproduction”

Ribonucleic acid (abbreviated RNA) is a nucleic acid present in all living cells that has structural similarities to DNA. Unlike DNA, however, RNA is most often single-stranded. An RNA molecule has a backbone made of alternating phosphate groups and the sugar ribose, rather than the deoxyribose found in DNA. What is RNA and its function? Function.Continue reading “RNA”

Deoxyribonucleic acid (abbreviated DNA) is the molecule that carries genetic information for the development and functioning of an organism. DNA is made of two linked strands that wind around each other to resemble a twisted ladder — a shape known as a double helix. Deoxyribonucleic acid is a polymer composed of two polynucleotide chains that coilContinue reading “DNA”

Blood is a body fluid in the circulatory system of humans and other vertebrates that delivers necessary substances such as nutrients and oxygen to the cells Karl Landsteiner. Father of blood grouping and immunochemistry. The breakthrough came when Karl Landsteiner, an Austrian scientist, discovered three human blood groups. These were the A, B and O blood groups.Continue reading “Blood”

In vertebrates, the gallbladder, also known as the cholecyst, is a small hollow organ where bile is stored and concentrated before it is released into the small intestine. In humans, the pear-shaped gallbladder lies beneath the liver, although the structure and position of the gallbladder can vary significantly among animal species. It receives and stores bile, produced by the liver, via the common hepatic duct,Continue reading “Gallbladder”

WHAT IS THE FUNCTION OF MUSCULAR SYSTEM? The muscular system is responsible for the movement of the human body. Attached to the bones of the skeletal system are about 700 named muscles that make up roughly half of a person’s body weight. Each of these muscles is a discrete organ constructed of skeletal muscle tissue, bloodContinue reading “Muscle System”
