Mammals, including humans, produce urea, whereas reptiles and many terrestrial invertebrates produce uric acid. Protonephridia. Urea (CH4N2O) is the nitrogenous waste excreted in urine by most mammals. Another cell type—parietal cells—secrete hydrogen and chloride ions, which combine in the lumen to form hydrochloric acid, the primary acidic component of the stomach juices. Two or more neurohormonal peptides with chemical and biologic properties similar to those of mammalian oxytocin and vasopressin are secreted by the vertebrate hypothalamus (except in Agnatha fishes, which produce only one).

The effect of acid rain on plants and animals can be mitigated under certain conditions, such as having a thick layer of soil and having certain types of bedrock under the soil to absorb the rain. The acidity of the stomach contents triggers the small intestine to secrete a hormone known as _____. The nervous and endocrine systems both work together to bring about this adaptation. Effects of Acid Rain on Plants and Animals. Because crocodiles and alligators tend to snap up large prey, they need to quickly break it down in their stomach before it begins to rot and poison them–the surge of acid breaks down their meal quickly enough to keep it from sickening them.

It is produced in many animals, mainly by the zona fasciculata of the adrenal cortex in the adrenal gland. Man, dogs, poultry and swine have simple or monogastric stomachs (see Figure 1). Animals such as birds and reptiles which must conserve water, excrete nitrogen as uric acid as a solid mixed with very small amounts of water. (The glands are shown in the illustration below.) Wild sturgeon’s roe offers a delicacy. This aorta switching trick allows them to then secrete stomach acid at a rate ten times faster than has ever been observed in any other animal. Concentrates are highly digestible feedstuffs that are high in energy and low in fiber. Herbivores can be either pregastric or postgastric fermenters (based on the site of fermentation in the GI tract). Concentrates are typically 80 to 90 percent digestible. The abomasum is comparable to the stomach in monogastric animals. Why do many egg-laying animals secrete uric acid as their waste product? Life Process Maintenance of living organism is … ureotelic: animals that secrete urea as the primary nitrogenous waste material; ornithine: an amino acid, which acts as an intermediate in the biosynthesis of urea; urea: a water-soluble organic compound, CO(NH2)2, formed by the metabolism of proteins and excreted in the urine; Nitrogenous Waste in Terrestrial Animals: The Urea Cycle. In experimental animals, highest concentrations of vitamin C are found in the pituitary and adrenal glands, and high levels are also found in the liver, spleen, brain and pancreas. All Rights Reserved. The paired glands located near the anus of whip scorpions secrete specific acids (formic acid and acetic acid) that serve as irritants and apparently are used for defense. Most dogs break down purines into allantoin, which is a soluble chemical that is excreted in the urine without problems. Acid secretion by gastric parietal cells occurs in a stepwise process. Therefore animals producing uric acid lose a little water with it. When crocodiles and alligators feast on their prey, their brain sends a signal to a special valve in their heart that restricts the flow of blood to their lungs and pumps a huge amount of blood to their stomachs. Actually, urea is a natural diuretic which insures the flow of urine. HCl does its job in the stomach cavity, or lumen. Animals such as birds and reptiles which must conserve water, excrete nitrogen as uric acid as a solid mixed with very small amounts of water. The process of passing into the bloodstream or lymph system the materials of nutrition. There are beings wh0 live, die and become part of nature again.
