Regeneration in humans Regeneration in humans Regeneration in humans is the regrowth of lost tissues or organs in response to injury. This is in contrast to wound healing, which involves closing up the injury site with a scar. Some tissues such as skin and large organs including the liver regrow quite readily, while others have been thought to have little or no capacity for regeneration. However ongoing research, particularly in the heart and lungs, suggests that there is hope for a variety of tissues and organs to eventually become regeneration-capable. In humans with non-injured tissues, the tissue is naturally regenerated over time; by
Body odor Body odor Body odor (American English) or body odour (British English) is present in humans and other animals, and its intensity can be influenced by many factors (behavioral patterns, survival strategies). Body odor has a strong genetic basis, but it can be also strongly influenced by various diseases and physiological conditions. Body odor is generally considered to be an unpleasant odor among many human cultures. In humans, the formation of body odors is caused by factors such as diet, gender, health, and medication, but the major contribution comes from bacterial activity on skin gland secretions. Humans have three types of
