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

Arterial Blood Gas Interpretation (ABG) Arterial Blood Gas Analysis is used to measure the partial pressures of oxygen (PaO2)‚ carbon dioxide (PaCO2)‚ and the pH of an arterial blood sample. Oxygen content (O2CT)‚ oxygen saturation (SaO2)‚ and bicarbonate (HCO3-) values are also measured. A blood sample for ABG analysis may be drawn by percutaneous arterial puncture from an arterial line. The ABG analysis is mainly used to evaluate gas exchange in the lungs. It is also used to assess integrity of

is activated by the rise in blood temperature and is responsible for for controlling the mechanisms that will decrease the blood temperature. Efferent nerve impulses are sent from the hypothalamus to multiple different corrective mechanisms to try to decrease the blood temperature and maintain it at approximately 37℃. The efferent nerve impulses causes the smooth muscles to relax and as a result‚ opens up blood capillaries near the surface of the skin. This is known as vasodilation as the blood

homeostasis related to aging and disease? 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.

reflexive behaviors that are elicited when certain stimuli are present. 2. Homeostatic Theories The assumptions of the homeostatic theory are that organisms attempt to maintain homeostasis‚ the balance of physiological state or equilibrium‚ by constantly adjusting themselves to the demands of the environment. It can be noted that every living thing has certain biological needs‚ sex‚ hunger‚ thirst‚ that is caused by imbalance because those variables are absent in the physical body. 3. Arousal Theory

requires a receptor‚ a control centre‚ and an effector. A receptor is the structure that monitors internal conditions. Receptors sense changes in function and begin the body’s homeostatic response. These receptors are connected to a control centre that studies all the information sent to it by the receptors. In most homeostatic mechanisms‚ the control centre is the brain. When the brain receives information about a change in the body’s internal conditions‚ it sends out signals along nerves. These signals

Maintaining a normal body temperature is crucial for optimal health and is one important aspect of homeostasis. Homeostasis is the body’s ability to balance varying internal conditions within narrow limits despite a constantly changing outside environment (Marieb & Hoehn‚ 2016). When a person is subjected to stimuli‚ which is a change in the variable‚ such as cold weather‚ temperature sensitive receptors in a person’s skin called thermoreceptors‚ detect this change. The receptors then respond providing
