Hyponatremia and decreased urine output are exhibited with syndrome of inappropriate secretion of antidiuretic hormone (siadh).
<h3>What is secretion of antidiuretic hormone (siadh)?</h3>
Syndrome of inappropriate secretion of antidiuretic hormone (SIADH) is a condition in which the body produces too much antidiuretic hormone (ADH). This hormone helps the kidneys control the amount of water the body loses through urine. SIADH causes the body to retain excess water. ADH is a substance that is naturally produced in an area of the brain called the hypothalamus. It is then released from the pituitary gland at the base of the brain.
There are many reasons why the body needs to produce large amounts of ADH. Common situations where ADH is (improperly) released into the blood when it shouldn't be produced include:
Drug therapy
During surgery General anesthesia
Brain disorders such as trauma, infections and stroke
Brain surgery involving the hypothalamus
Pulmonary disorders such as tuberculosis, cancer, chronic infections and pneumonia
Substance abuse
Rare causes include: There is a thing Pituitary
Leukemia and cancer of the small intestine, pancreas and brain
Psychiatric disorders

The developing fetus also needs its waste substances removing. The fetus is protected by the uterus and the amniotic fluid , a liquid contained in a bag called the amnion.
This period is referred to as the Great Oxygenation Event. This period saw the evolution of photosynthetic organisms (cyanobacteria) that utilized carbon dioxide (that dominated the atmosphere then) and sunlight to manufacture their energy molecules-glucose. Photosynthesis produces oxygen as a byproduct that is evolved into the atmosphere. As these photosynthetic organisms proliferated on earth, the atmosphere composition changed to become partly dominated by oxygen (which is an oxidaton agent) with less and less carbon dioxide.
In this laboratory you will be learning how to use one of the most important tools in biology –
the compound light microscope – to view a variety of specimens. You will also use a slightly
different type of light microscope called a stereoscopic dissecting microscope
