Homeostasis is the body's ability to maintain stable internal conditions despite external changes. A variable is the factor being regulated (such as temperature, etc.) • Communication is essential for homeostasis and is accomplished by the nervous and endocrine systems.

For any given variable, such as body temperature or blood glucose level, there is a particular set point that is the physiological optimum value. The set point for human body temperature, for example, is about 37 degrees C (98.6 degrees F). As the body works to maintain homeostasis for temperature or any other internal variable, the value typically...
Homeostasisis normally maintained in the human body by an extremely complex balancing act. Regardless of the variable being kept within its normal range, maintaining homeostasis requires at least four interacting components: stimulus, sensor, control centre, and effector. 1. The stimulusis provided by the variable being regulated. Generally, the st...
Body temperature regulation involves negative feedback, whether it lowers the temperature or raises it, as shown in Figure 7.8.3 and explained in the text that follows. The human body’s temperature regulatory centre is the hypothalamus in the brain. When the hypothalamus receives data from sensors in the skin and brain that body temperature is high...
In controlling the blood glucose level, certain endocrine cells in the pancreas (called alpha and beta cells) detect the level of glucose in the blood. They then respond appropriately to keep the level of blood glucose within the normal range. 1. If the blood glucose level rises above the normal range, pancreatic beta cells release the hormone insu...
When a wound causes bleeding, the body responds with a positive feedback loop to clot the blood and stop blood loss. Substances released by the injured blood vessel wall begin the process of blood clotting. Platelets in the blood start to cling to the injured site and release chemicals that attract additional platelets. As the platelets continue to...
Figure 7.8.6 shows the positive feedback loop that controls childbirth. The process normally begins when the head of the infant pushes against the cervix. This stimulates nerve impulses, which travel from the cervix to the hypothalamus in the brain. In response, the hypothalamus sends the hormone oxytocinto the pituitary gland, which secretes it in...

May 19, 2023 · Homeostasis's ultimate goal is to help the body maintain a constant and relatively stable internal environment whenever possible. For example, being in hot weather triggers cooling mechanisms, such as sweat, that keep the body's core temperature around 98.6 degrees F.
Oct 22, 2024 · Homeostasis is any self-regulating process by which an organism tends to maintain stability while adjusting to conditions that are best for its survival. If homeostasis is successful, life continues; if it’s unsuccessful, it results in a disaster or death of the organism.

Jul 31, 2022 · Explain how different organ systems relate to one another to maintain homeostasis. Each organ system performs specific functions for the body, and each organ system is typically studied independently. However, the organ systems also work together to help the body maintain homeostasis.
