The abdominal organs may be classified as solid organs or hollow organs. The solid organs are the liver, pancreas, spleen, kidneys, and adrenal glands. The hollow organs of the abdomen are the stomach, intestines, gallbladder, bladder, and rectum. [6] In the thoracic cavity, the heart is a hollow, muscular organ. [7]
This organ is responsible for sending and receiving messages from the body and its environment. Each part of the brain is specialized for different aspects of the human being. [ 5 ] For example, the temporal lobe has a major role in vision and audition, whereas the frontal lobe is significant for motor function and problem solving. [ 2 ]
The notion of system (or apparatus) relies upon the concept of vital or organic function: [2] a system is a set of organs with a definite function. This idea was already present in Antiquity (Galen, Aristotle), but the application of the term "system" is more recent.
The internal human body includes organs, teeth, bones, muscle, tendons, ligaments, blood vessels and blood, lymphatic vessels and lymph. The study of the human body includes anatomy, physiology, histology and embryology. The body varies anatomically in known ways. Physiology focuses on the systems and organs of the human body and their functions.
This article contains a list of organs in the human body. It is widely believed that there are 79 organs (this number goes up if you count each bone and muscle as an organ on their own, which is becoming a more common practice [1] [2]); however, there is no universal standard definition of what constitutes an organ, and some tissue groups' status as one is debated.

This new definition, the irreversible loss of the capacity for consciousness and for spontaneous breathing, and the essentially unchanged 1976 tests held to establish that state, have been adopted as a basis of death certification for organ transplant purposes in subsequent Codes of Practice.
According to the cardiocentric hypothesis, the heart is the primary location of human emotions, cognition, and awareness. [1] This notion may be traced back to ancient civilizations such as Egypt and Greece, where the heart was regarded not only as a physical organ but also as a repository of emotions and wisdom. [2]
Élan vital was translated in the English edition as "vital impetus", but is usually translated by his detractors as "vital force". [citation needed] It is a hypothetical explanation for evolution and development of organisms, which Bergson linked closely with consciousness – the intuitive perception of experience and the flow of inner time.
