Human Body | Human Anatomy and Physiology

www.mifada.com -- Principle of Human Anatomy & Physiology Anatomy represents the structure and Physiology refers the function. Anatomy and physiology of Human describe every aspect of how the human body sustains life. The principle pieces of information can be categorized into five areas. 1. Levels of OrganizationThe body is organized into levels that build upon each other. It begins with the smallest atoms and molecules that control the chemical reactions required for the body to function. The basic structural and functional units in the body---cells---are the next level. Learning how different cells work is key to understanding how organs and systems function. 2. Support and Movement The bones in the skeletal system support soft tissues, protect internal organs and create a structure that enables movement. Three types of muscle---smooth, cardiac, skeletal---are responsible for motion, the production of heat and maintenance of posture. Physiology looks at the chemistry of muscle contraction and the development of different types of bones and muscle. 3. Systems of ControlThe systems that control the body are the nervous system and the endocrine system. The nervous system has two parts: the central nervous system (CNS) and the autonomic nervous system. 4. Maintaining Homeostasis. Homeostasis is a state of balance. Nothing in the body functions properly or remains healthy without homeostasis. Homeostasis is maintained by the cardiovascular, lymphatic, respiratory, digestive ...

Using sodium hydroxide (drain cleaner) we dissolve glass. Glass is nearly invulnerable to chemicals and thus why it's the preferred material for chemical containers and reaction vessels. But when exposed to molten sodium hydroxide even glass will dissolve. To perform the reaction a steel container is used as it's resistant to the sodium hydroxide.
