The act of breathing is achieved by 4 process as following: 1- Pulmonary ventilation: Pulmonary ventilation is defined as the act of moving air into and out of the lungs in order to achieve inhalation and exhalation. However negative pressure system and muscles contraction are used by our respiratory system to allow the air to flow in and out of the body. Negative pressure system function is to make the pressure of the alveoli lower than the atmosphere pressure, this can be achieved by the assistance of the pleural membrane, where pleural membrane impresses the lungs when they are at rest, as a result the air will flow into the lunges in order to rise up the lunges pressure until it matches the atmosphere pressure, at this point the diaphragm will contract and more air can be inhaled, meanwhile the contraction of external intercostal muscle will cause an increment in the thorax volume, so as a feedback the lungs pressure will go lower than the atmosphere pressure
Veins transport blood to the heart and lungs at low pressure after receiving it from the capillaries. Valves inside the veins keep blood moving in one direction. The human body's arterial system branches out from one main artery, the dorsal aorta. Like veins, arteries have three layers: an outer layer of tissue, an inner layer of epithelial cells and a layer of muscle in between. Arteries deliver oxygenated blood to the capillaries, where the exchange of oxygen and carbon dioxide takes place.
The signs and symptoms of COPD include shortness of breath, chronic cough, fatigue and having bluish lips and nail beds (American Lung Association, 2014). The second vital human body system is cardiovascular system (CVS). CVS plays an integral role in enhancing and facilitating the proper function of heart in order to allow the body to function as a whole. CVS comprises of two components namely heart and blood vessels. Heart is a four-chambered muscular pumping organ that divides into atriums and ventricles that are separated by valves to prevent backflow of blood among the compartments (Smeltzer, Bare, Hinkle, & Cheever, 2010).
A patient is treated depending on its cause. For alkalosis caused by hyperventilation, breathing into a paper bag allows you to keep more carbon dioxide in your body, which improves the alkalosis. If your oxygen level is low, you may receive oxygen. Medicines may be needed to correct chemical loss such as chloride and potassium (Respiratory alkalosis, 2014) Because of their delicate fluid and electrolyte status the elderly are at risk for metabolic
Pathophysiology The present of a patent foramen ovale is required to permit blood flow across the septum into the left atrium, the patent duct arteriosus allows blood to flow to the pulmonary artery into the lungs. VSD allows a modest amount of blood to enter the right ventricle &pulmonary artery. Thus pulmonary blood flow is diminished. Clinical manifestation - Cyanosis - Tachycardia - Dyspnea - Hypoxia with clubbing Management For neonates whose pulmonary blood flow depends on the patency of the ductus arteriosus, a continuous infusion of Prostaglandin E1, is started until surgical intervention can be arranged. Palliative treatment: A Bidirectional Clenn shunt can be performed at 6-9 month.
Describe how the body systems affect one another. How body systems affect each other is for example when the circulatory system works with the respiratory system. They work together because when you breathe in you take in oxygen and the respiratory system does its job and then the circulatory system takes the oxygen and sends it to your other parts. 3. Explain how cells are important to tissues.
My mode is Duo Positive Airway Pressure on the Hamilton G5. It is pressure control, a set inspiratory pressure is set to be proportional to patient inspiratory pressure. The breath sequence is intermittent mandatory ventilation (IMV). Ventilatory support is between mandatory and spontaneous breaths. The rate setting directly affects the number of mandatory breaths and the level of ventilatory support.
6-78). It is the passageway between the pharynx and the stomach. “Each end of the esophagus is encircled by muscular sphincters that act as valves to regulate passage of material. The upper esophageal sphincter in the cervical part of the esophagus helps prevent air entering the esophagus during
Introduction Ventilation is a process which consists of two parts: inhalation and exhalation. Inhalation is the movement of air into the lungs, while exhalation is the movement of air out of the lungs. During this process, the diaphragm shrinks and the intercostal muscles move the ribs upwards, which increases the area and decreases the pressure. When the diaphragm and the intercostal muscles rest, the area decreases and the pressure increases pushing the air out. Hence, different body positions, such as bending down while sitting, can reduce the lung capacity, thus, the rate of respiration, as the empty space in the lungs is reduced.
Stratum Lucidum III. Stratum Granulosum IV. Stratum Spinosum V. Stratum Basale 1.2.2. Dermis It is middle layer which contain connective tissue, sweat gland, hair follicles, collagen, blood vessels, nerves and various glands. Function of dermis layer is to provide strength, elasticity and to cushion the body stress and strain.
