ORGANISM‚ a living individual. Homeostasis With all of the activities going on in the organism‚ there must be guidelines and limits that the body must follow in order to preserve health. The body must maintain a STABLE INTERNAL ENVIRONMENT‚ even when external environment is changing. The term used to describe the body‟s ability to maintain these stable conditions is HOMEOSTASIS. ( Ex. thermostat and heater and temp regulation in the hypothalamus.) Homeostasis regulated by feedback: Compare

Experiment 1 Background Diffusion is a process‚ in relation to the spontaneous movement of molecules from an area of high concentration‚ to an area of low concentration down a concentration gradient. It is a type of passive transport method‚ that requires no cellular energy (ATP). This movement occurs‚ until a state of equilibrium has been established on both sides of the membrane. The diffusion of molecules happens at cellular level‚ through a cell membrane via the pores. The cell membrane

The combination of these systems allows the body to function properly and maintain unconscious homeostasis. I will also be talking about the effects that fitness and diet have on these processes. The pulmonary circuit passes already-used‚ deoxygenated and carbon dioxide-rich blood from the heart to the lungs in order for that the blood to become oxygenized

Anatomists deal with the structure (morphology) of the body parts. This includes the shapes‚ forms‚ and placement of body organs and appendages. Physiologists deal with the functions of body parts‚ what the body parts do‚ and how this is accomplished. 3. How does a biological structure’s form determine its
