How does the lungs structure make the lungs suitable?
You have the trachea, that lies in the center of your chest. You have ten major bronchi, that arise from the trachea on left and right side. Then there is branching and re-branching of the bronchi. This happens in right angles to each other, most probably. The process continue for 17 generations. Then the alveoli starts. They branch for six times. This creates the enormously large surface area of the lungs. It is about 100 square meters or 1100 square feet. This is how the lung structure is suitable. You have much efficient mechanism in case of the fish. In which the water current flows via gills. There is no dead space in in fish, like the land animals. But then, you have ample oxygen in the air as compared to water and your lungs are considered as very much efficient.
Does the right lymphatic duct arise from the cysterna chyli?
No, the right lymphatic duct does not arise from the cisterna chyli. The right lymphatic duct drains lymph from the upper right side of the body and empties into the right subclavian vein. The cisterna chyli is a dilated sac at the lower end of the thoracic duct that collects lymph from the lower half of the body.
What pairs of spinal nerves arise from the cord of these 31 pairs are cervical nerves how many pairs are thoracic nerves how many pairs are lumbar nerves and how many are sacral nerves?
31 pairs. And they arise from the combination of the ventral and dorsal roots.
What are the small branches of the bronchial called?
BronchiolesThe bronchioles or bronchioli are the first airway branches that no longer contain cartilage. They are branches of the bronchi, and are smaller than one millimeter in diameter.There are no glands or cartilage in any of the bronchioles, and the epithelial cells become more cuboidal in shape.The bronchioles terminate by entering the circular sacs called alveoli.Control of airflow resistance and air distribution in the lungs is controlled by the bronchioles.
What veins travel from the lungs to the heart in?
There are actually two sets of arteries and veins going to and from the lungs. The first set are the pulmonary artery and vein. The pulmonary artery takes blood from the right atrium, takes it to the lungs where the blood is oxygenated and loses some of its carbon dioxide. It is then taken back to the heart by the pulmonary vein, which is the only vein in the body to carry fully oxygenated blood. The other set of vessels carrying blood to the lungs are referred to the bronchial vessels, and supply oxygen and nutrients to the lung tissue itself. These arise from the thoracic aorta or intercostal vessels and run alongside the airways (trachea, bronchi, bronchioles, etc) and much of the blood is returned via the pulmonary vein due to a large bronchial-to-pulmonary shunt that exists via many anastomoses between the two blood supplies.
What causes a tracheoesophageal fistula?
It's a birth defect in which there is an abnormal connection between the esophagus and the trachea. There may be an extra connection between the esophagus and the trachea or the esophagus may be a blind tube.
What is the future tense of arise?
Will arise (for example, I will arise).
When are the esophagus and trachea created in a womb?
In the earliest fetal stage, the trachea, which is the windpipe, and the esophagus, which is the foodpipe are still a single tube called the primitive foregut. The primitive forgut divides into two tubes between the 23rd and 28th day of pregnancy - that's often before the woman even knows she is pregnant.
What is the future tense of arose?
Will arise e.g. "The thought will arise..."
What are anagrams for arise?
