The pressure changes in the four chambers on the heart (two atria’s and two ventricles) allow the blood to continuously flow in one direction. This is also aided by the valves (artioventricular and semi lunar valves). The circulatory system consists of the heart as well. The heart is a complex
List the structures and functions of the lymphatic system. The lymphatic system consists of capillaries, vessels, nodes, and other organs that transport a fluid called lymph from the tissues as it returns to the bloodstream. The lymphatic tissues of the organs filters and cleans the lymph of any debris, abnormal cells or pathogens. It also transports fatty acids from the intestines to the circulatory system. 3.
CO poisoning can cause serious implications such as organ failure, heart damage, and brain damage. Death may occur in cases when your body begins to replace the oxygen in your blood with CO. Treatments will help prevent life-threatening complications. Oxygen Treatment – This treatment helps increase the oxygen levels in the blood and remove the CO from the person’s blood. An oxygen mask is paced over the patient’s nose and mouth then be asked to inhale.
There are two such sinuses in the pericardial cavity: the transverse pericardial sinus and the oblique pericardial sinus. Both these are formed during embryonic folding of the heart tube during ontogeny. The reflections (folds) of the serosal layer result in the formation of a set of complex tubes, one enclosing the aorta and the pulmonary trunk and the other enclosing the superior and inferior vena cave and the pulmonary veins. This results in a transverse sinus across the pericardium that separates the arterial blood vessels and the venous blood vessels. The index finger can pass though the transverse sinus, which helps surgeons to identify the blood vessels of the heart during coronary artery bypass surgery.
Some normal allergens incorporate dust, and dirt • Viral diseases can influence the cilia and cause an amassing of bodily fluid in the sinus depressions. • The cilia can't work well when there are issues in the invulnerable framework. Therefore they can't secure the body against disease. • Issues of the nasal depressions, for example, a strayed septum, can impede the sinus entries. • Colds and influenza cause the body to deliver more bodily fluid.
Inside the chest cavity is a pair of lungs that is surrounded with membranes (pleura). Between the pleura and the lung tissue is a potential space that is lubricated with a thin layer of fluid. This keeps the pleura and the lung tissue sliding against each other and allows for lung expansion. Sometimes, conditions such as infection (pneumonia), traumatic bleeding or cancer can fill this space with inflammatory fluid, which can solidify and make the pleura adhere to the lungs. It forms a capsule that can entrap the lungs and make breathing difficult.
So, what is the definition of health care associated infections? They are infections that patients acquire while being hospitalized to receive treatment for their conditions either medical or surgical. Many of the HCAIs are preventable. In the modern healthcare, there are many types of invasive procedures that is used to treat patients to help them recover, also some devices are used, and all can be a potential risk for transmitting an infection to the patient while receiving the treatment. Instruments used during surgery can be a source of Infection, catheters are a source of urinary tract infections, and ventilators are a source of respiratory tract infections.
When its full the pressure causes the bicuspid and tricuspid valves to open and blood flows into the ventricles. Contraction of each atrium now forces any remaining blood into the ventricles. The ventricles now contract (systole) and the atria relax (diastole). The pressure closes the bicuspid and tricuspid valves causing the first sound of the heartbeat. The contraction of the ventricles opens the semilunar valves, forcing blood into the pulmonary artery and aorta.
It allows the cells to pass through. Then, it also where the process of exchanged between blood and lymphatic vessels occur. Due this process, it allows the lymphatic system to monitor the invading microbes. The lymphatic vessels also carry a clear fluid that it bathes in the body’s tissues that is known as lymph. Another organ is lymph node that is has specialized compartments where the immune system there and can encounter antigens.
The cell’s secretion help on lubricating the heart, preventing heart friction with its surrounding organs during contractions, holding the heart inside the chest and maintaining a hollow space for the heart to expand into when it is full of blood. 1.1.2 Structure of the heart wall The heart wall is composed of 3 layers (figure 3): • Epicardium: As mentioned before, the epicardium is at the same time the outermost layer of the heart wall and the inner wall of the pericardium (visceral layer). It protects and lubricates the
One of the most common disease that affects the respiratory system is asthma. Asthma is a long duration disease that diminishes the airways of your lungs. It makes you have further difficulty breathing. The cause of the disease is not known. Researchers consider that some of the causes for asthma could be inherited or the environment could also have been something that affects your lungs and made it hard for you to breathe.
The main symptom of CF is the mucus that builds up in the airways. This can cause frequent infections. People with CF tend to get different infections than people without it; these infections generally can’t be treated with antibiotics. They can also get many sinus infections, bronchitis, and pneumonia (“Signs and Symptoms”). Cystic fibrosis also affects the digestive systems of patients.
