The littoral zone is the zone at the edge of a lake or ocean or in aquatic habitat which is alternatively exposed to air, hence, light is also available and immersed in water.
This costal zone is rich producers from surface to bottom, with a large number of brown and red alga attached at the zone.
Different zones is an aquatic ecosystem-
Pelagic zone- Any zone of water in a sea or lake that is neither close to bottom nor the shore is pelagic zone.
Benthic zone- It is the bottom part of the water body (aphotic zone) light is not available here and it is dark. microorganisms and benthic organisms are found in this zone.
Lentic zone- refers to standing or relatively still water in an aquatic ecosystem.

 thyralet hormomein. Meyrold etiarul relno mentetes a proteir herrneme called thyrocalcitomin (Tr.I) which reggulaten the blood caleturn leveln. 22.2.5 Parathyroid Gland In humans, four parathyrold glands are present on the back side of the thyrold gland, one pair each in the two lobes of the thyroid gland (Figure 22.3b). The parathyrold glands seerete a peptlde hormone called parathyrold hormone (PIH). The secretion of PIH tn regulated by the circulating levels of calcium ions. Parathyroid hormone (PTH) increases the levels in the blood. PIH acts on bones and stimulates the process of bone resorption (dissolution/ demineralisation). PTH also stimulates reabsorption of Ca-by the renal. tubules and increases absorption from the digested food. It is, thus. clear that PTH is a hypercalcemic hormone, 1.e. it increases the blood in the body. 22.2.6 Thymus The thymus gland is a lobular structure located between lungs behind sternum on the ventral side of aorta. The thymus plays a major role in the development of the immune system. This gland secretes the peptide hormones called thymosins. Thymosins play a major role in the differentiation of T-lymphocytes, which provide cell-mediated immunity. In addition, thymosins also promote production of antibodies to provide humoral immunity. Thymus is degenerated in old indtviduals resulting in a decreased production of thymosins. As a result, the immune responses of old persons become weak.
