what are the three factors that affect a cells homeostasis?
475926
Three factors that influence homeostasis are discussed: fluids and electrolytes, energy and nutrition, and immune response mediators. Cell injury induces changes in the sodium-potassium pump that disrupt fluid and electrolyte homeostasis, and surgery causes changes in functional extracellular fluid.

The ANS helps to maintain homeostasis (internal stability and balance) through the coordination of various activities such as hormone secretion, circulation, respiration, digestion and excretion.

Homeostasis is generally maintained by a negative feedback loop that includes a stimulus, sensor, control center, and effector. Negative feedback serves to reduce an excessive response and to keep a variable within the normal range. Negative feedback loops control body temperature and the blood glucose level.

Environmental factors that affect plant growth include light, temperature, water, humidity, and nutrition. It is important to understand how these factors affect plant growth and development.

Factors affecting health and well-being These include socio-economic, physical, environmental and behavioural factors. The three aspects of health and well-being that can be affected by any of these factors are physical health and well-being, social health and well-being and psychological health and well-being.

Lesson Summary Those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution. Some things, such as a virus, demonstrate only a few of these characteristics and are, therefore, not alive.

Answer and Explanation: The nervous system maintains homeostasis by rapidly controlling body functions.

Homeostasis is the maintenance of a stable level of internal conditions even though environmental conditions are constantly changing. Metabolism is the sum of all the chemical reactions that take in and transform energy and materials from the environment. All living things grow and increase in size.

Micronutrients (vitamins and minerals) have key roles in numerous homeostatic processes, enabling the body to produce enzymes, hormones and other substances that are essential for energy production, cell maintenance and repair, immune function and recovery from illness, blood formation, and maintenance of vital organs.

Explanation: Homeostatic imbalance occurs when cells in the body experience a deficiency, such as nutritional deficiencies resulting from an unhealthy diet or when cells are exposed to toxins. ... 2) External influences such as nutrition deficiencies, physical activity, mental health , drug and alcohol abuse.
