which the internal environment of the body remains relatively constant despite changes in the external environment. Examples would be the maintenance of body temperature and levels of glucose in the blood Homeostatic mechanisms are designed to reestablish homeostasis when there is an imbalance.

produced. Oxygen and glucose are the main sources of energy for ATP. The muscle cells‚ liver cells and kidneys cells use ATP at a high rate to maintain homeostasis. The loss of oxygen and blood glucose to his organs will cause him to have a homeostatic imbalance and many of his organ cells will die causing them to lose functions. If his heart has stopped‚ waste removal will come to a stop. His blood flow aids in removing waste products with needed products to maintain homeostasis. Carbon dioxide is

It is vital for our body to maintain homeostasis for our survival‚ this ability of the body allows us to adapt to our environment which is why we can live in a variety of different settings3. The mechanism of every homeostatic control has three interdependent components; the receptor‚ which is a sensor that responds to a change (stimuli) in the environment‚ by sending information through the afferent pathway to the control center1. The second component‚ which is the control

B. Assuming Joseph’s heart has stopped‚ what cellular processes and membrane functions are going to be affected by loss of oxygen‚ blood glucose‚ and waste removal? Once the heart stops beating‚ blood‚ with oxygen and glucose‚ is not delivered to the body and ATP is not able to be produced. Without ATP production‚ cells are unable to function‚ oxygenation will not remain‚ blood glucose will not be controlled‚ and delivery of nutrients through the cell membrane and waste removal will cease‚ causing

Provide examples to support your thinking. -The lack of homeostasis (called homeostatic imbalance) can cause several different types of diseases and disorders. Homeostasis will make sure of the efficiency in control functions of the body. Diabetes‚ gout‚ and any disease caused by a toxin in the bloodstream result from homeostatic imbalance. 2.

Diffusion Experiment: Osmosis in Sucrose Solutions Abstract We used dialysis tubing to simulate a semi-permeable membrane. Since molecules diffuse from their higher concentration to their lower concentration‚ water will move across the membrane in response to this concentration. While conducting this lab we were able to observe passive transport through diffusion and osmosis. Introduction Osmosis is a specialized case of diffusion that involves the passive transport of water. When

Physiology often focuses on events at the cellular or molecular level. A. Anatomy – studies the structure of the body parts and their relationship to one another. i. Developmental – concerns structural changes that in the body occur throughout the lifespan. Embryology studies the developmental changes
