Sure i will! how was your day/night?
Answer:
Explanation:In physiology, a stimulus is a detectable change in the physical or chemical structure of an organism's internal or external environment. The ability of an organism or organ to detect external stimuli, so that an appropriate reaction can be made, is called sensitivity. Sensory receptors can receive information from outside the body, as in touch receptors found in the skin or light receptors in the eye, as well as from inside the body, as in chemoreceptors and mechanoreceptors. When a stimulus is detected by a sensory receptor, it can elicit a reflex via stimulus transduction. An internal stimulus is often the first component of a homeostatic control system. External stimuli are capable of producing systemic responses throughout the body, as in the fight-or-flight response. In order for a stimulus to be detected with high probability, its level of strength must exceed the absolute threshold; if a signal does reach threshold, the information is transmitted to the central nervous system (CNS), where it is integrated and a decision on how to react is made. Although stimuli commonly cause the body to respond, it is the CNS that finally determines whether a signal causes a reaction or not.
Answer:
The correct answer is e) Collecting duct, aldosterone, vasopressin
Explanation:
ADH( antidiuretic hormone) is called vasopressin formed by the hypothalamus gland and released when the body is under stress of shortage of water.
This hormone binds to the water channel receptors present in the collecting duct and opens them. Then the water is released in the interstitial space and returns to the blood by reabsorption.
Decrease in the blood flow results in the release of aldosterone which regulates the blood pressure by absorbing the water and sodium ions from the collecting duct increasing blood volume and osmolarity.
