The respiratory system is the main mechanism by which the body replenishes its oxygen supplies and removes waste products from cellular respiration such as carbon dioxide. The main function of the respiratory system is to facilitate the intake and removal of gaseous materials from the body. The major organ systems of the human body are the respiratory system, vascular system, skeletal system, and the digestive system. In a nutshell, an organ system is a collective group of organs that work together to perform some specific function. In addition to dividing the human body by anatomical region, one can also categorize the parts of the human body by organ system. Except for some parts of the face, the limbs, the hands in feet, in particular, contain the most nerve endings are so are specialized to sense touch. Humans are unique among tetrapods (organisms with 4 limbs) in that 2 are specialized for locomotion (legs/feet) and 2 are specialized for manipulating objects (arms/hands). The limbs are attached to the torso and their primary purpose is to interact with the environment via locomotion with the legs and manipulating objects with the arms. The next important division of the human boy is its 4 limbs. The torso also contains the majority of blood vessels that provide oxygen to the whole body. The main function of the torso is to provide shape and structure to the human body and to house its vital internal organs such as the heart, lungs, stomach, intestines, liver, and kidneys. The torso or “trunk” is the largest section of the human body and composes the bulk of the human body. The head is probably one of the more delicate parts of the human body, as the vascular and musculature structures of the head consist of a number of small interconnected parts that need to be situated very particularly to function properly.
The primary purpose of the head is to contain and support the brain and primary sensory organs such as the mouth, eyes, ears, and nose. The human head consists of a fleshy outer portion covering a bony substructure called the skull. The main organ systems of the human body are the respiratory system, the vascular system, the skeletal system, and the digestive system. In addition to the physical external parts, the human body can also be divided by organ system and the parts that compose those systems. In general, the human body can be divided into 3 main anatomical areas: head, torso, and limbs. The study of the macroscopic morphology and function of the human body is called gross anatomy. The human body has many secrets, and it does not divulge them to anyone, except those who have learned to wait.” - Paul Auster
“The human body is strange and flawed and unpredictable. This list of human body parts includes common anatomical divisions and the body parts that compose those divisions. The human body collectively is the most complex machine known to man, Like any machine, the human body is made of different body parts situated in some particular way with the goal of performing some function.
