The cell is the fundamental structural and functional unit of all living organisms and anything less than a complete cell has no independent existence. In 1665, Robert Hooke observed a thin section of cork under a compound microscope, noticed a honey-comb like compartments. He coined the term “Cell”. In 1674, Anton Von Leeuwenhoek first saw […]
The sensory system represents an integration of the functions of the PNS and CNS. The Sensory Division of the Peripheral Nervous System gathers information about the Body’s Internal Conditions and External Environment. The human experience is affected by both internal and external stimuli. Humans are able to distinguish among many different types of stimuli by […]
The Urinary System is a group of organs in the body concerned with filtering out excess fluid and other substances from the bloodstream. The substances are filtered out from the body in the form of urine. Urine is a liquid produced by the kidneys, collected in the bladder and excreted through the urethra. Urine is […]
The nervous system is the combination of the brain, spinal cord and the complex network of neurons. This system performs and responsible for various functions like sending, receiving, and interpreting information from all parts of the body. The nervous system also responsible for monitoring and coordinates the internal organ function and responds to changes in […]
Human Reproductive System is made up of the external and internal organs of both males and females and works together for reproduction. The reproductive system is the most important system in our body because it plays an important role in the survival of species. The growth and activity of these parts are regulated by hormones. The […]
The respiratory system provides the route by which the supply of oxygen present in the atmospheric air, gain entry to the body and it provides the route of excretion of co². The cells of the body need energy for there chemical activity that maintains homeostasis. Most of this energy is derived from take place in […]
The muscular system allows us to move, flex and control our bodies. Practicing yoga is a good example of the voluntary use of the muscular system. The word Muscles refer to all contractile tissue. The term muscle comes from the Latin word mus, which means “mouse,” because the movement of muscles looks like mice running […]
The lymphatic system is a vascular network of tubules and ducts that collect, filter and return lymph to blood circulation. Lymph is a clear fluid that comes from blood plasma, which exits blood vessels at capillary beds. This fluid becomes the interstitial fluid that surrounds cells. Lymph contains water, proteins, salts, lipids, white blood cells, […]
The skeletal system is the internal framework of the body which provides support and protects the soft organs of the body. The skeletal system is the collection of bones, cartilage, ligaments, and tendons and account for 20% body weight. The skeleton is the structure that gives us our shape and offers a supportive framework for […]
The Human body consists of at least 200 distinct types of cells. These cells contain essentially the same internal structures yet they vary enormously in shape, size, and functions. The different types of cells are not randomly distributed throughout the body; rather they occur in organized layers, a level of an organization referred to as […]
