Introduction Planarians are able in creating new individuals from their body parts. This process is popularly known as regeneration and the factor shows that when the planarians are cut into several parts, each part gets the form of a new organism. The process differs from that of reproduction as regeneration can happen from any part of the organism. An example of this factor is that the tail of a lizard is cut down but after some time a new tail is formed. What is Regeneration? Regeneration is considered the process of development of a complete organism from the different parts ... Read More

Introduction Regeneration is a method where an organism breaks up into different parts with the help of special cells. It refers to the capacity of the organisms to generate damaged or lost body parts. Here each of the parts can also further produce individual organisms. In the case of regeneration, the organisms are not able to form a new cell suddenly. Instead of this, the specialised cells form a mass of cells and it is changed further to create different cells. Figure 1: Regeneration in Planaria Information regarding Regeneration Regeneration is considered to be a natural process and ... Read More

Introduction The process of reproduction is classified into two divisions - they are known as sexual and asexual reproduction. During the time of sexual reproduction, there are two of the same species that share an offspring by giving some of the traits. The second type of reproduction is known as asexual reproduction.

In this form of reproduction, all the species can extend the existence of their order to live on the planet. ... Read More

Introduction The system of renin-angiotensin is basically attached with the generation of blood pressure by modulating the water reabsorption, vascular tone, sodium reabsorption and volume of blood. Their primary function is building resistance vessels, instigating the delivery of sodium at different levels, stimulating vascular and cardiac hypertrophy, and many others. What is Renin? Renins are defined as one of the most remarkable enzymes that are secreted by the kidneys of human beings. There are probabilities of being liberated by body placenta as well. The enzyme plays a very significant role in the complete physiological system, as it helps in ... Read More

Introduction Coordination is the process that aids in the function and interaction of the organs and complements the function of each other. The neutral system helps in the integration of the bodily functions of humans. The neural system provides an organized network to point-to-point connections which are helpful in rapid coordination. It functions with the endocrine system that helps in rendering the chemical integration with the help of hormones. What is the Neural System? The neural system assists in the functionalities of various organs in the human body. It is composed of highly specialized cells that are known ... Read More

Introduction The nervous tissues are considered the primary tissue in the nervous system. The nervous tissue is the part of the cellular unit that helps in the basic functionalities of the body. These tissues help in monitoring and controlling basic bodily functions in living organisms. Nervous tissues are made of two cells: neurons which are also called nerve cells and glial cells, these cells transmit nerve impulses and provide nutrients to neurons. What is Nervous Tissue? The nervous tissue is the primary tissue of the nervous system. It helps in the coordination process and controls overall functioning of the body ... Read More

Introduction Nervous system deals with the major functions of the body, it controls major body processes or systems including digestion, sexual development or puberty, etc. The nervous system also plays a vital role in controlling thoughts, memory, movements, and automatic motor response of the body. Nervous system can get damaged due to several external factors including viral infections, diseases, toxins, and the natural ageing process. What is the Nervous System? Nervous system is the complex system that acts as the command centre of human body. It helps to maintain the body system and experience the surroundings. The system comprises a ... Read More

Introduction Nervous system Coordination can affect the whole body including memory to feel and can control the sense so, that the brain can interpret what one person can see, taste or touch. In simple words, the whole body can be controlled and coordinated for various activities by the nervous system and its coordination. Nerves help to send and receive the message that too in form of an electrical impulse, is called the nerve impulse. Control and Coordination in Human Control and coordination are the kinds of activities that take place via the nervous system and the organs, that comprise ... Read More
