entities that work together to carry out a particular task. In higher forms of organisms such as humans, the biological systems includeintegumentary system, lymphatic system,muscular system,nervous system,reproductive system,respiratory system,skeletal system,endocrine system,urinary system, andimmune ...
Endocrine system– one of the most essential systems of the body as it controls thehomeostasis, growth, and metabolism functions of the body through communicating with different parts of the body via the action of different hormones, such as thyroxin, corticoids, sex hormones, and other hormones ...
By this time theorgansystems—circulatory, digestive, endocrine, excretory, integumentary, muscular, nervous, reproductive, respiratory, and skeletal—had been defined, both anatomically and functionally, and research efforts were focussed on understanding these systems in cellular and chemical terms, an ...

The onset of diapause depends upon a combination of environmental factors operating on the regulatory mechanisms—i.e., nervous andendocrine systems—of the insect. Photoperiod and temperature influence the endocrine function of the brain, which synthesizes and secretes a substance (hormone) that contr...
Examples of specialized cells include heart muscle cells and parietal cells found in the stomach. The hierarchy that forms parts in living organisms follows this order; atoms, molecules, organelles, cells, tissues, organs, organ systems. Various organ systems form an organism. ...
Define the role of the endocrine system in homeostasis using two examples. How do organ systems maintain homeostasis? Homeostasis is a characteristic shared by all living organisms on the earth. Explain the importance of homeostasis. What processes does t...
Endocrine glands do not have excretory ducts. Instead, their product, called hormone, diffuses into capillaries and travels through the bloodstream to reach its target organ/s and modify their functions. Endocrine epithelial cells can be organized in three ways; Forming parenchyma of endocrine gland...
can also regulate secretions of the endocrine system by the action of neurohormones. The nervous systems of invertebrates vary from a simple network of nerves to a complex nerve network under the control of a primitive brain.See alsoautonomic nervous systemcentral nervous systemperipheral nervous ...
