What is difference between organ and gland?

Vital Organs

An organ is a self-contained group of tissues that performs a specific function in the body. The body’s organs are grouped into organ systems based on the functions they perform. Humans have 11 different organ systems.

  1. Integumentary (skin, hair, nails)
  2. Skeletal (bones)
  3. Muscular (smooth, cardiac, and skeletal muscles)
  4. Circulatory (heart, arteries, veins)
  5. Respiratory (lungs, diaphragm, larynx)
  6. Digestive (stomach, intestines, liver)
  7. Urinary (kidneys, ureters, bladder)
  8. Immune (lymph nodes, bone marrow, thymus)
  9. Nervous (brain, spinal cord, nerves)
  10. Endocrine (pituitary gland, thyroid, adrenals)
  11. Reproductive (penis, vagina, prostate, uterus) [2]

Multisystem Organ Failure [ edit | edit source ]

Multisystem organ failure is commonly encountered in the intensive care setting, often requiring a multi-disciplinary approach to management. It is increasingly being recognised that organ failures do not exist in isolation, but rather result from and have an impact on the dysfunction of other organs, mediated by haemodynamic, neurohormonal, and cell signaling feedback mechanisms, an interplay that has been termed organ cross-talk. Common examples of this relationship between organ systems include cardiorenal, hepatorenal, and pulmonary-renal syndromes, each of which has a significant impact on the likelihood of recovery of individual organs and overall prognosis [3]
