The Endocrine System Endocrine System produces chemicals that signal organs and whole body systems to do things. endocrine glands sends chemical secretions directly into the blood, without the use of tube.The substances produced by endocrine glands are called hormones. Hormones are chemical substances ...
Hormones are chemicals produced by specific tissues that are transported by the vascular system to affect other tissues at low concentrations. 2. The endocrine and nervous systems are integrated in their control of physiological processes. Synthesis of Hormones 1. Protein hormones are initially ...
Humans are ubiquitously exposed to, exogenous chemicals that act as endocrine disruptors. There are many different types of phthalates and their metabolites have varied capacities for modifying the endocrine system1,2,3. They are known to interact through peroxisome proliferator‐activated receptors (PPAR...

No matter how old you are, stress, infections, and being around certain chemicals can also mess with parts of your endocrine system. Your genes or lifestyle habits can increase your chances of an endocrine disorder like hypothyroidism, diabetes, or osteoporosis. ...
Any gland of the body that produces hormones and secretes them directly into the bloodstream. In mammals, the thyroid gland, adrenal gland, and pituitary gland, as well as the ovary, testis, and pancreas are all endocrine glands. ♦ The group of endocrine glands together with the hormones ...
The effects that many of these chemicals may have on aquatic organisms are mostly unknown, particularly when complex mixtures are considered. The greatest amount of evidence for the potential impact of pharmaceuticals on the aquatic environment (via endocrine disruption) currently comes from one of the...
Several recent publications reflect debate on the issue of “endocrine disrupting chemicals” (EDCs), indicating that two seemingly mutually exclusive perspectives are being articulated separately and independently. Considering this, a group of scientists with expertise in basic science, medicine and risk ...
However, in the human heart, there is an exclusive excitatory structure that produces rapid electrical impulses. This exclusive structure is termed as the “pacemaker of the heart”. The sinoatrial node (SA node) serves the purpose of the pacemaker in the mammalian heart. From this node, the ...
Obesogens are ingested or internalized chemicals that alter energy metabolism, increasing adiposity. Many act via alterations in endocrine signaling. They disrupt signaling pathways (e.g., hormone receptors, transcription factors, ROS) in various cell types and tissues that regulate energy intake and ...
