Patho Review 2/18/19. Human body, the physical substance of the human organism. Definition. The physical being called a person consists of 11 distinct human body systems, all of them vital for life, and their functions often reflect their names: cardiovascular, digestive, endocrine, integumentary, lymphatic, muscular, nervous, reproductive, respiratory, skeletal and urinary. danielle_espejo TEACHER. OTHER SETS BY THIS CREATOR. The Human Microbiome Project (HMP) is the organization fueling the majority of this research and they are attempting to catalogue the different bacteria and their functions in the body in a similar way to how the Human Genome Project catalogued the human genome. Survival depends on the body's maintaining or restoring homeostasis, a state of relative constancy, of its internal environment. Other organs and tissues serve a purpose in only one body system. Your body uses hormones to control growth, development, metabolism, reproduction, mood, and other functions. Characteristic of the vertebrate form, the human body has an internal skeleton with a backbone, and, as with the mammalian form, it has hair and mammary glands. Human Body Structure. Learn more about the composition, form, and physical adaptations of the human body. The major cavities of the human body are the spaces left over when internal organs are removed. Some organs may be part of more than one body system if they serve more than one function. The Human Body Cavities. 54 terms. Information. Note: Students should focus on the fact that systems work together not necessarily on the names of each organ. a) the cells in the retina of the eye absorb light ...

Movement. There are different cavities in the human body that house various organ systems. Survival is the body's most important business. This two-way information flow into, and out of, the CNS is conveyed by the peripheral nervous system. The central nervous system definition is that it receives information from the body’s environment and generates instructions, thereby controlling all the activities of the human body. ... We asked scientists to define where, exactly, those boundaries lie, and to provide some take-home tips that’ll help you stretch your own potential. The lymph system is extremely closely related to the circulatory system, and the activity of the respiratory system feeds directly into the circulatory system. There are total 11 systems in human body containing their specific organs hence are called as organ systems. There are additional body cavities which we will only discuss in lecture. Pushing The Limits Of The Human Body. Body functions are the physiological or psychological functions of body systems. The body's functions are ultimately its cells' functions. Human body internal parts such as the lungs, heart, and brain, are enclosed within the skeletal system and are housed within the different internal body cavities.
