Homeostasis

“In order for all of the cellular functions to be carried out successfully, the body’s internal environment must always be in a state of homeostasis (consistency)” (Cellular). Claude made the discovery of homeostasis. Before Bernard, there was basically nothing known about homeostasis. He was the first to define the term milieu interieur, or also known as homeostasis (Claude 4). "The living body, though it has need of the surrounding environment, is nevertheless relatively independent of it.…

The Central Nervous System is the most important organ system in the human body because it is how we control our body. It consists of the spinal cord, nerve cells, and parts of the brain (Organ System Skit). “The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain” (How Does the Nervous System Work? NCBI). In addition, when the body wants to move, the brain sends a message to the…

Our body needs to have an equilibrium in order to function properly. The process that is known to stabilize and regulate our body to function properly is called homeostasis. The homeostatic mechanism has three components: the receptor, the control center and the effector. Receptors are one of the components that provide the information of the sudden fluctuation in the body, then they transmit a signal from the nerves to the control center. The control center processes that information and…

organization, metabolism and energy use, response to stimuli, regulation and homeostasis, growth and development, evolution, and reproduction. Viruses share many of these characteristics, while lacking some and others debated upon. Many scientists argues that viruses are alive because viruses have levels of organization. All living organisms contain small building blocks that come together to make…

Systems theorists believe individuals, their systems, communities, and environment are all interrelated to achieve better interactions between each other (Robbins, Chatterjee, & Canda, 2011). Micro, mezzo, and macro systems levels, as well as homeostasis will be discussed to explain the causes of excess death and how to decrease or eliminate excess death. Micro System The CEO, lab supervisor, janitor, and unemployed mother are impacted by their micro systems. Their micro systems…

I really found the chapters challenging this week! Every week, I am more amazed at how complex our bodies are. The amount of different systems, and processes needed to maintain homeostasis constantly. The complex way the body heals itself, is amazing as well. The first year of our lives, our skeletal system replaces itself 100 percent. The rest of our lives, it slows down to replacing about ten percent of itself yearly. That is a huge difference!! Bones remodel themselves in a lifelong process…

Filaggrin is one of the proteins that are found in skin and that regulate epidermal homeostasis. In order to discuss about the function of this protein, the role of skin should be overviewed first. Skin is the largest organ and has an important role in keeping the homeostasis of an organism. It consists of three layers: epidermis, dermis and subcutis. All these layers act together to maintain the integrity of a tissue and sustain the proper functioning of an organ. However, skin is a dynamic…

In today’s busy world, most people have lives that are filled with frustrations, deadlines, and demands. For many, stress becomes so common that it occurs every day and becomes a way of life. Stress is not always bad. Stress, when it does not exceed a certain level, can help people perform better since they are under pressure. It can also be used as a motivator to complete a task quicker and better. However, when stress exceeds a certain point, life can become overwhelming and can result in…

Instincts are unpredictable, unlearned practices that have a settled example all through a species (evolutionary perspective). Drive-reduction theory proposed that the purpose of biological drives is to correct disturbances of homeostasis. In psychological terms, homeostasis is the process of preserving an individual’s secure mental and emotional state under different…

The Body’s Response to Stress Kimberly Shafto Ocean County College BIOL-131-DL1 The endocrine system and ANS work together in times of stress to maintain homeostasis. The autonomic nervous system (ANS) is divided into two subdivisions the sympathetic, and parasympathetic. They sympathetic nervous system activates the “fight or flight” response which causes a rise in heart rate, pupil dilation, increased sweating, and blood pressure. The parasympathetic nervous system activates…
