Negative thoughts will of course impact ones homeostatic state, in turn affecting ones overall wellbeing and health. The three are very much entwined and impinge on each other. Perfect homeostasis equals better health which in turn is better for one’s wellbeing. Homeostasis is also affected by other aspects such as ones digestive system, cardiovascular system or respiratory system which brings me to my next point, The circulatory and respiratory
The process of ventilation provides air into the alveoli of the lungs. This is where gas exchange occurs. Gases diffuse across the membrane between the alveoli and the capillaries into the bloodstream according to Fick’s law: the rate of diffusion of a gas tissue is proportional to the tissue area, difference in partial pressure and is inversely proportional to the thickness , i.e. oxygen passes into the blood from alveoli and carbon dioxide exits the blood into the alveoli. The atmosphere consists of oxygen, nitrogen and carbon dioxide as well as other gases.
The heart forces the ‘oxygenated’ blood through a range of connecting blood vessels specifically speaking arteries which travel around your body providing your cells with the necessary materials that the blood contains. As the blood reaches your cells the oxygen is released in order for the cells to function. The cells then give out waste materials which can include co2 and water. In order for your blood to receive these waste products they absorb it. We now have deoxygenated blood which goes through your veins aiming towards your heart.
Introduction The human respiratory system is a series of organs responsible for taking in oxygen and removing carbon dioxide, a waste product that if allowed to accumulate, can be lethal. The respiratory system works with the circulatory system in that the red blood cells collect the oxygen from the lungs and carry it to the parts of the body where it is needed. This project will take you through the functions and anatomy of the of the respiratory system, the mechanics of breathing, the disorders of the system and how massage or holistic approaches can be used to treat these diseases instead of traditional medical routes. Functions of the Respiratory System Through breathing, inhalation, and exhalation, the respiratory system facilitates
The blood is brick red in colour because it has oxygen and carbon dioxide. I understand this from reading L. Tucker’s book. The cardiac cycle The cardiac cycle is the sequence of events that occur when the heart beats. According to L. Tucker, the following occurs during the cardiac cycle: • The left and right atria contract, forcing blood into the
Blood in oxygen from the systemic circulation enters the right atrium from the superior and inferior vena cava and passes to the ventricle. From here it is pumped into the pulmonary circulation, through the lungs where it receives oxygen and gives off carbon dioxide. Oxygenated blood then returns to the atrium, passes through the left ventricle and is pumped out through the aorta to the systemic circulation_ where the oxygen is used and diabolized to carbon dioxide. Describe the condition Hypertension: This is blood pressure that consistently remains above the normal level of 120/80. Causes: kidney disease, smoking, alcohol and diet.
The blood is a body fluid that circulates constantly. It transports oxygen to the cells by the work of the red blood cells which contain haemoglobin. White blood cells attack, destroy and remove abnormal and old cells and also fight infectious agents and foreign substances. Platelets take part in blood clotting. Plasma which constitutes about 55% of the blood circulates dissolved nutrients
I. The circulatory system is one of the most important function in our body. It provides nutrients and oxygen to the tissues and cells and removes waste products produced by the cells. As the blood travels throughout the body, it picks up nutrients from the small intestine, oxygen from the lungs and hormones from the endocrine gland and delivers these materials to the cells. Once delivered, the blood picks up the waste products and carbon dioxide produced by the cells and transfers it back to the lungs.
Examples include being late, argument, exercise (voluntary or involuntary), etc. This triggers hyperventilation state, which triggers increase in respiratory rate, therefore supplying body with higher oxygen content; stimulate sympathetic release previously mentioned which releases cortisol, noradrenaline and adrenaline chemicals into the bloodstream, increasing cardiac output and total peripheral resistance, therefore increasing heart rate and blood pressure; which pumps more oxygen at a faster rate throughout the body. Shortly after, parasympathetic release will kick in and acute stress responses dissipate. Due to being short-term stress, there is no time for extensive irreparable damage to be done, but their post-stress symptoms present: muscular problems (like pulled muscles, tendons and ligaments leading to headaches, back pain), and post emotional stress like irritability, anger, anxiety or depression.

These electron chains are oxidised, transferring all of their electrons to their carrier molecules which are embedded in the ECT membrane. NADH enter the electron transport chain. The FADH2 originate in the citric acid cycle. In the first part of this process, electrons that pass from NADH to the electron transport chain, flow through the remaining complexes. NADH is oxidized to NAD during process.
Another important factor in HFOV is amplitude ; that refers to the pressure of the oscillating diaphragm 8-90cm H2O. When the amplitude is increased oscillation is increased resulting in improved gas mixing. Increasing the altitude will lower PaCO2 and decreasing the amplitude will increase PaCO2. Inspite of the promising therapy the HFOV can provide, there are many drawbacks: 1) need special ventilator, 2) can not switch from this mode to another 3)there are no alarms in this type of ventilator and therefore frequent assessment is needed, 4) mucous plugging is common,
The low body temperature from the cooling pads causes the immune system to slow down. Typically, a strong immune system is extremely crucial to the body’s overall health from exterior infections and diseases; however, during the process of induced hypothermia, a decrease in immune system is prefered because it reduces the risk of inflammatory reactions. In a healthy body, inflammatory reactions are important because they will create an increase in blood circulation, which will normally help fight off
Higher muscle lactate accumulation and venous plasma lactate concentration is observed in a high ambient temperature compared to a moderate temperature. It was previously shown that muscular glycogen utilization is enhanced in during exercise under high temperature (Febbraio et al., 1994). Therefore it is thought that the increase concentration of lactate in muscle under high temperature is caused by accelerated anaerobic glycolysis. Thus more lactate is released into the blood stream. When the exercise to exhaustion in the high temperature happens, muscle glycolygen are not exhausted.
Weaning ( Liberation from the ventilators) from the Ventilators: The new and preferred term for taking the pateint out of ventilator support is liberation not weaning. There is some difference in these two terms. During weaning there is a gradual reduction of pressure or volume support and then weaned from the ventilator. Conversely, liberation is a term used for frequent assessment to see whether the patient can breathe spontaneously without support and based on that observation extubated. There are important criteria to be fulfilled before extubation.
Impaired gas exchange is a nursing diagnosis for a patient suffering current or future problems with oxygen/carbon dioxide balance (unknown, 2012). Gas exchange is the passage of oxygen and carbon dioxide in opposite directions across the alveolocapillary membrane (Miller-Keane, 2003). With impaired gas exchange a patient can have an excess or deficit in oxygenation and/or carbon dioxide elimination at the alveolar-capillary membrane (Gulanick & Myers 2014). The structure and organization of the lung is meant to maximize its surface area to increase gas diffusion. Having such a large surface area increases the amount of gas that can diffuse into and out of the lungs.
