You've lost your interest in sex. Having little or no desire in the sack could be a side effect of a thyroid disorder. Too little thyroid hormone could be a contributor to a low libido, but the cumulative impact of other hypothyroidism symptomsâweight gain, low energy, and body aches and painsâcould also play a part.
Excretion is the process by which metabolic wastes and other non-useful materials are eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys and skin. This is in contrast with secretion, where the substance may have specific tasks after leaving the cell. Excretion is an essential process in all forms of life. For example, in mammals urine is expelled through the urethra, which is part of the excretory system. In single-celled organisms, waste products are discharged directly through the surface of the cell.
to excrete is to get rid of something from your body. In this case you are probably referring to the end of the gastrointestinal system and possibly the urinary system. Either way, they get rid of wastes in the body that if built up would cause harm to the rest of the body.
