Thoracic cavity

What are the nonpolar parts of a phospholipid? c. Tail group 4. This is the only polar portion of a cholesterol molecule and it forms hydrogen bonds with the polar heads of phospholipids. d. –OH group 5. This type of membrane protein will extend throughout the entire membrane touching both the Intracellular fluid and the Extracellular fluid. e. Integral proteins f. Transmembrane proteins g. Integral proteins and Transmembrane proteins Ans: D…

2-year-old Kyle has been diagnosed with whopping cough, also known as Pertussis. The American Thoracic Society (2015) defines Pertussis as a very contagious respiratory infection, caused by a bacterium called Bordetella pertussis. The bacterium causes infection of the lungs and airways and is transmitted through close personal contact, sneezing and coughing. The main symptom, a cough which then progresses to intense bouts of coughing. These bouts can be followed by vomiting, choking or a sharp…

close the velopharyngeal port. The levator veli palatine, uvulae muscle, and tensor veli palatine are responsible for the elevation of the soft palate to approximate the posterior pharyngeal wall. This is to prevent material from entering the nasal cavity. Next, the hyoid bone also known as the floating bone moves forward and elevates as well as the larynx. The suprahyoid and infrahyoid muscles are responsible for the hyoid bone movement. Additionally, hyolaryngeal excursion creates a vacuum in…

the larynx. The main function of the pharynx is to provide a passageway for the respiratory and digestive tracts. Esophagus: The esophagus is in charge of bringing food down from the mouth and leading it to the stomach. It is located in the thoracic cavity underneath the trachea and appears much less firm than the trachea. The esophagus belongs to the digestive system. Stomach: The stomach is located underneath the left side of the liver. It looks like a thin oval shaped balloon that is part…

Everyday our bodies need oxygen and different nutrients to function properly but in order to maintain that constancy, our blood has to be constantly moving. And in order for our cells to get transported and get everything they need, the heart needs to be beating. The cardiovascular system makes sure the levels of substances in the blood is constant by transporting these substances as circumstances change. The heart is located in the lower part of the mediastinum between the lungs. Most…

The human body is composed of muscle which are responsible for body movement. Muscles in found in the human body attach to the bones of the skeletal system, in a human body there are “700 individual muscles that make up part of a person’s weight and the muscular system. Each of these muscles are separate organ which are made up of skeletal tissues, nerves, blood vessels and muscle tissues. Muscle tissues are found throughout the human body, inside the heart, the blood vessels and the digestive…

affected (Westerdahl et al, 2016). The surgery process itself may also affect the respiratory system by traumatizing the cells and muscles in general, thus reducing the capacity of the lung for respiring and breathing. One study suggests that the thoracic cavity may also have been traumatized by the surgery and difficult to get back into the previous full function (Vargas et al, 1997). If the heart cannot pump blood properly to the lungs, the lungs may not be able to perform optimally as well…

Patients with ADPKD may be at a higher risk of developing thoracic aortic aneurysms. Abdominal aortic aneurysms are not increased among these patients. Pain may also develop for reasons completely unrelated to the underlying disease; thus, abdominal pain in patients with ADPKD may be a diagnostic challenge. In addition to pain, other physical symptoms that patients with early-stage ADPKD may report include fatigue, breathlessness, weakness, and malaise.[24] Hematuria Hematuria frequently is the…

the suffix –clast is from the Greek word meaning to break. Therefore, Osteoclasts are large cells that function to reabsorb, or digest, bony tissue. It does so by digesting bone tissue from the inner sides of the bones thus enlarging the inner bone cavity so that the bone does not become overly thick and heavy. 3. How do Osteoblasts assist when recovering from a fractured bone? Osteoblasts assist in the recovery from a fractured bone by laying down the bone matter (calcium salts) there after…

These converge to form one of two vessels called lymphatic trunks. One is the right lymphatic duct which drains the upper right portion of the body and returns the lymph to the bloodstream via the right subclavian vein. The other trunk is called the thoracic duct and drains the remaining part of the fluid into the left subclavian vein. The lymph is transported along the system of vessels by muscle contractions and the valves prevent the lymph from flowing backward. The vessels are punctuated at…
