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

Homeostasis The conditions inside our body must be very carefully controlled if the body is to function effectively. Homeostasis is the maintenance of a constant internal environment. The nervous system and hormones are responsible for this. One example of homeostasis is the concentration of carbon dioxide in the blood being carefully controlled. Here are some of the other internal conditions that are regulated: Body temperature This is controlled to maintain the temperature at which the

``DIFINITION The muscular system is an organ system consisting of skeletal‚ smooth and cardiac muscles. It permits movement of the body‚ maintains posture‚ and circulates blood throughout the body Muscles provide strength‚ balance‚ movement and heat for the body to keep warm There are three distinct types of muscles: skeletal muscles‚ cardiac or heart muscles‚ and smooth (non-striated) muscles Skeletal muscle is a form of striated muscle tissue existing throughout the human body‚ and which

“Calcium Homeostasis” Kayla Smith Anatomy and Physiology I BSC 1085C Ref# 82458 Calcium plays a very significant role in our bodies. Approximately 99 percent of the calcium in our bodies is stored in the teeth and bones. Calcium generates about two percent of our total body weight. Calcium is crucial in bone formation‚ keeping strong bones and teeth and is known for helping to prevent osteoporosis. Although calcium is mostly thought about in the bones and teeth‚ it also plays important roles

Muscular system is the system of Human Body that provides motor power for all movements of body parts. Muscular system is composed of special tissue called muscular tissue. Muscles have the ability to contract actvely to provide the force for movements of body parts. Muscular system is an important system of human body because without it‚ life will completely stop. Muscles produce not only those movements that are under the control of our will and that we can see and feel‚ but also those movements

The Skeletal System provides us with many important functions. It provides us with the shape and form for our bodies as well as supporting‚ protecting‚ allowing our body to move freely‚ producing blood for the body‚ and storing minerals. The Skeletal System is the system of our body that gives our body its physical shape and with the help of the Muscular System it keeps us moving and makes us able to do tasks that we don’t think about like raising our leg to kick a football or using our legs to boost

Homeostasis by definition is the technical term for the process of maintaining a constant internal environment despite changes in the external environment. The internal environment comprises of blood‚ tissue fluid‚ body cell contents and all metabolic processes taking place inside the body. This process is essential to the survival of a person and to our species as a whole. The liver‚ the kidneys‚ and the brain (hypothalamus‚ the autonomic nervous system and the endocrine system) help maintain
