The endocrine system works with the nervous system to maintain homeostasis. The endocrine system secretes hormones in the human body‚ which are produced in endocrine glands and are released into the bloodstream to travel to the its specific target cell‚ tissue‚ or organ. Exocrine glands produce chemicals that are discharged into the surroundings. Hormones can either produce short-lived responses or long-term responses. An example of a short-lived response is when adrenaline (epinephrine)causes the

1. Briefly explain how does the body maintain homeostasis? Homeostasis is a existence and maintenance of a relatively constant internal environment. Homeostasis is maintain by negative and positive feedback mechanism. Most homeostatic control mechanisms are negative feedback mechanisms. In these system‚ the output shut off the original stimulus or reduce its intensity. These mechanisms cause the variable to change in a direction opposite to that of the initial change‚ returning it to its “ideal”

Homeostasis is a mechanism that allows organisms to maintain stable internal conditions (Reece 2014). The capability to perform homeostasis is essential for the survival of all organisms. Homeostatic mechanisms include a range of responses that regulate internal imbalances‚ including body temperature. A vital component of homeostasis is known as thermoregulation‚ the process of maintaining temperatures within a normal range (Reece 2014). When ambient temperatures change‚ animals must control their

Homeostasis Homeostasis refers to the ability of the body or a cell to seek and maintain a condition of equilibrium or stability within its internal environment when dealing with external changes. It is involved in the maintenance of the constant internal environment which includes the function of kidney‚ liver‚ skin‚ etc. In humans‚ homeostasis happens when the body regulates body temperature in an effort to maintain an internal temperature around 98.6 degrees Fahrenheit. For example‚ we sweat to

maintenance of the entire organism. While cells‚ tissues‚ and organs may perform very different functions‚ all the cells in the body are similar in their metabolic needs. Maintaining a constant internal environment by providing the cells with what they need to survive (oxygen‚ nutrients‚ and removal of waste) is necessary for the well-being of individual cells and of the entire body. The many processes by which the body controls its internal environment are collectively called homeostasis. The complementary

Homeostasis‚ also spelled homoeostasis (from Greek: ὅμοιος‚ "hómoios"‚ "similar")‚ is the property of a system in which variables are regulated so that internal conditions remain stable and relatively constant. Examples of homeostasis include the regulation of temperature and the balance between acidity and alkalinity (pH). It is a process that maintains the stability of the human body’s internal environment in response to changes in external conditions. The concept was described by Claude Bernard

Magnitude and duration of the stress determine just how the body will react. It is important to understand metabolic changes that take place in reaction to stress‚ both in uncomplicated

Homeostasis What is it? Maintenance of a relatively constant internal environment The human body is constantly responding to internal and external factors in order to maintain relative stability within the body Homeostasis is vital to the body as a whole‚ right down to each individual cell. If homeostasis is not maintained at the cellular level this will affect the body as a whole. History Claude Bernard (1813-1878): consistency of internal environment is the condition for free life.

Homeostasis Why might the special senses of smell and taste be important for helping to maintain homeostasis in the body? The French scientist Claude Bernard first suggested the concept of homeostasis in the 19th century. He defined homeostasis as the fact that all living things maintain a constant internal environment. Homeostasis is the tendency of the body to maintain a relatively consistent internal state. The nervous system sends and receives signals about temperature‚ hydration‚ blood
