Adipose tissue functions to store energy, insulate, and provide padding, especially in the skin and around the kidneys and heart.Adipose Tissue Human sec X 200Reticular Connective TissueReticular connective tissue contains an abundance of reticular fibers. In the nose, external ear, and the walls of the trachea it functions to support the softer tissues.The intervertebral disks function as shock pads.The fetal skeleton of vertebrate animals is composed of cartilage before bone forms

In larger bronchioles, the epithelium is still ciliated, but is now usually simple columnar, whereas in the smallest bronchioles, the epithelium will be simple cuboidal (mostly Clara cells) and lack cilia altogether. What are the differences among pulmonary arteries and veins and bronchial arteries? AnswerPulmonary arteries are a part of a low-pressure system (pulmonary blood pressure is much lower than systemic) and, therefore, have thinner walls

In the bovine ligamentum nuchae, the pattern of birefringence indicates that there are two micellar structures, one arranged circularly on the outside and the other arranged axially in the centers of the fibers. Apart from the odd bit of scapular, joint, or costal cartilage, there is virtually no cartilage in most meat cuts, yet all my life I have found chewy strands of connective tissue in tough cooked meat and I have called them "gristle"

Immediate medical attention is needed if a patient is so short of breath that they can't speak, their lips or fingernails turn gray or blue, their heartbeat is usually fast, or if they're not mentally alert. European pulmonologists have been investigating the device for four years, but researchers at UPMC believe that only a large, randomized trial can medically prove the device's effectiveness

If the axial fibers lose their tethering at their most distal ends, as happens with a loss of alveoli, they will recoil, and the resultant airway shortening could lead to the obstruction of small airways (Fig. Finally, given this uncertainty regarding the pathologic progression of emphysema in COPD, it may be time to think about reconsidering the definition of emphysema

As time goes on and the disease progresses, the amount of exercise necessary to produce breathlessness diminishes, both because of the progressive gas exchange problem but also because of the other physiologic disturbances in lung function and generalized debility

The word is sometimes applied to the respiratory apparatus of lower animals.The human lungs are paired organs, located on either side of the heart and occupying a large portion of the chest cavity from the collarbone to the diaphragm.

The respiratory system of whales certainly has some unusual features, but they are adaptations to prevent water entering the airways: the nasal passages are complex and convoluted, and the larynx (the upper end of the respiratory tube) extends up into the nasal cavity rather than opening into the throat. To do so, they must make their ascent slowly, making the appropriate decompression stops, so that nitrogen and other inert gases can be voided gradually through the lungs

Tissues and organs subject to expansive forces contain elastic fibers, such as, the walls of arteries, the vocal cords, skin, the trachea and the bronchi. The tough, inelastic tendonous sheets and cords formed by tendons provide great resistence to pulling forces, e.g., a pencil thick tendon has been found to support up to 1000 pounds

If the abscess is a complication of pneumonia, the symptoms tend to be moderated to an exaggeration of the pneumonia symptoms.When a lung abscess forms, it is in the acute stage and treatment with antibiotics usually is effective. The most obvious carcinogen, however, and the one most widely encountered, is tobacco smoke, especially cigarette smoke, which is much more frequently and deeply inhaled than the smoke of pipes or cigars.A study based on autopsies of the lungs of individuals who had died from many varied causes, but whose smoking history was known, showed that unrecognized cancer and precancerous changes in tissue were numerous among smokers and rare among nonsmokers

The major determinant of the mechanical properties of most connective tissue is the extracellular matrix which is secreted by the cells within it (fibroblasts in ordinary connective tissue, osteoblasts and chondroblasts in bone and cartilage respectively). Collagen is secreted by fibroblasts as procollagen molecules, converted extracellularly into tropocollagen which self-assembles into microscopically visible fibers and grossly evident mechanical structures such as tendons
