The function of arteries pulmonalis is to replace the carbon dioxide and water vapor that exists in the blood with oxygen. 4. Aortic Valve Aortic valve is the valve that separates the left ventricle with the aorta. Blood pressure changes on both sides of valve caused the valve can be opened and closed. The function of the aortic valve is to prevent blood flowing in the wrong direction.
The digestive system requires the mouth, throat, esophagus, stomach, small intestine, large intestine, pancreas, liver and gallbladder. Digestion is originated in the mouth, with the reaction of salivary amylase. Food is them proceed to the esophagus and in the stomach. The chewed food motion by the muscular movement is known as peristalsis, from the mouth to the pharynx, and then transferred to epiglottis that is a canvas over the larynx. The epiglottis is sealed off from the air passageway due to possible choking.
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 food then travels into the oesophagus. Your oesophagus is located near your trachea (windpipe). The epiglottis separates the nasal cavity and the lower airway from the passage of food whilst swallowing. The contractions of the muscles in your oesophagus push the food down your oesophagus and into your stomach. Your stomach is a hollow organ that holds food whilst it is being broken down by the enzymes.
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.
The alveoli are lined with simple squamous epithelium because the very thin epithelium will facilitate the diffusion of oxygen and carbon dioxide. 2. Explain how specific muscular contractions lead to quiet breathing. The muscles used for quiet breathing are the external intercostal and the diaphragm. Upon inspiration
The pulmonary system is the system at which the body is able to ventilate air in and out of the body. In this case we utilize oxygen that is being brought into the body and carbon dioxide that use blow off as a by product. The pulmonary system is also a purely pressureized system that is based all on gradients/partial pressures of air. The diaphram and the external intercostal muscles are important in this case because they will increase the volume inside the chest cavity which in turn decreses the pressure. The air from outside the body then rushes in because of this lower pressure that we have inside now.
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.
The bolus then goes to the pharynx where swallowing occurs. During deglutition in the pharynx there is a “flexible flap of elastic cartilage that’s function is to keep food out of the lower respiratory passages” called the epiglottis (Human). The bolus then goes to through the esophagus where segmentation(circular muscle contractions of esophagus that allows the bolus to mix) and peristalsis(longitudinal muscle contractions of the esophagus that allows the bolus to be push down bolus to the stomach) happens. Then it goes through “ringlike muscles that contract/close a bodily passage or opening” called sphincters (Sphincter). The bolus goes through one called the gastroesophageal between the end of the esophagus and the beginning of the stomach in order to enter the stomach.
Aortic valve: This is found in-between the left ventricle and the aorta The left atrium tightens and relaxes which allows for more blood to enter the left ventricle. As the heart muscle tenses and relaxes, it allows for blood to flow into the ventricles, atria and various times. Allowing a full intake and out-take of blood. What is special about the pulmonary artery and vein? Why?
