Harman [31]

Answer: Thymus gland

Explanation:

The thymus gland is an endocrine gland that is located in the upper part of the human chest. It is responsible for producing white blood cells. This gland is located near the airway. The enlargement of the thymus gland can suppress the nearby structures. This may result in shortness of breath, and cough along with sputum. The thymus gland produces several endocrine hormones like thymopoietin and thymulin.

The given condition is indicative of the mass of the thymus gland.

In order to improve patient relations, a family practitioner should ____
Helen [10]
In the field of medicine we have a short adage that goes, "To cure sometimes, to treat often, to comfort always." Some say it was Hippocrates himself who said this. With that in mind, doctors should always have the patient's welfare in mind always. To improve relations with the patient, the doctor must do a lot of things to show respect. One of them includes simply sitting on a chair with an open stance and leaning slightly forward at an angle while the patient is talking to show that you are interested in what he or she has to say. Never hold the door knob while the patient is still talking as this is a sign that you want him to leave as soon as possible. Never look at far away things, like paintings on the wall or a clock, while the patient is talking because this is another sign of disinterest. And always allow the patient to express his or her self fully without interruption. There are more ways to improve patient relations but these are some good pointers to begin with.

Where should the origin of the swim bladder be placed on the phylogenetic tree?
dolphi86 [110]

Answer:

At the base of Actinopterygii

*This is a unique characteristic of this group.

Explanation:

A peculiar characteristic organ observed in ray-finned fish (as well as in Sarcopterygii, or lobe-finned fish) but not in cartilaginous fish like shark is the swim bladder.

This organ is often described to be a sac containing gas. It helps these set of fish adjust its buoyancy and its position in the water by regulating the concentration of gas present in it.

The swim bladder is formed as a pouch coming off the embryonic digestive tract, and in chondrosteans and holosteans, with a set of teleosts e.g. the eels, it maintains an open pathway to the esophagus. In majority of the bony fish, the swim bladder is totally sealed off, as gas levels in their swim bladder are regulated by producing gas into the bladder via a network of capillaries, the rete mirabile (Latin word for "marvelous net").

The swim bladder is homologous to the lungs of tetrapods. Since they are formed in the same vein. Few fishes that have an open swim bladder employs it as a breathing organ.
