Answer:
"The organs have blood vessels as well as the nerves in it, the organ is also present within the organ motif is also being executed in these organs. So as eye. Epithelial tissue helps in protection against the microbes so as skin having different layers."
Explanation:
Eye is an organ because, the organs have blood vessels as well as the nerves in it, the organ is also present within the organ motif is also being executed in these organs. Similarly, inside the eyeball there is an organ which is known as retina, with is connected with the neural and epithelial tissue which helps in detection of the light which enters into the eyeball.
Skin is an epithelial tissue because, epithelial tissue helps in protection against the microbes. Similarly skin is composed of different layers of epithelial tissue which is also supported by the layers of connective tissue, helps in protection of internal organs from damage as well as dehydration.
The correct answer is HPA axis.
The Hypothalamic-Pituitary-Adrenal (HPA) axis is one of the most important neuroendocrine systems, which regulates the stress response and other functions such as the digestion, mood, emotions and the immune system.
The hypothalamus, when triggered by a possible stressor, releases two hormones; the vasopressin and the corticotropin-releasing hormone (CRH). CRH, in turn, triggers the release of the adrenocorticotropin hormone (ACTH) from the pituitary gland. As a result of the secretion of ACTH, cortisol is secreted by the adrenal cortex.
Cortisol is a steroid hormone, considered to be our body's stress hormone.
