Gnoma [55]

Answer:

78701

Explanation:

The nuclear imaging examination is done to accompany the blood as it transported to the kidneys in order to reveal whatsoever blockage and to assess the level of which the kidneys perform filtration. The case study does not pinpoint to the capability of the kidneys tubes and ducts.

In the CPT® Index view for Nuclear Medicine/Diagnostic/Vascular Flow leads us to code range 78701-78709. Since mainly vascular flow was undertaken, we can infer that code 78701 is the right code to report.

¿ Cuales son los sistemas que intevienen en el proceso de nutricion? ¿ Que funcion cumple cada uno de ellos en ese proceso?
Papessa [141]

Answer:

digestivo, respiratorio, circulatorio y excretor

Explanation:

El proceso de nutrición consiste en la ingesta de alimentos, los cuales son posteriormente transformados en energía y estructuras celulares que el organismo necesita para funcionar normalmente. Durante este proceso, intervienen cuatro sistemas:

- Sistema digestivo: descompone químicamente los alimentos en nutrientes. Los alimentos son sometidos a un proceso de fragmentación mecánica y digestión química. En primer lugar, los alimentos son triturados en la boca por los dientes, mezclados con saliva para formar un bolo alimenticio que llega al estómago donde los jugos gástricos los transforman en una papilla conocida como quimo. A continuación, los nutrientes llegan al intestino delgado donde son mezclados con el jugo pancreático y la bilis del hígado para ser absorbidos por la sangre. Finalmente, los compuestos que no fueron absorbidos llegan al intestino grueso donde se absorbe lo que queda de agua y lo demás es eliminado.

- Sistema respiratorio: los pulmones son los órganos encargado del proceso de respiración mediante el cual el organismo intercambia gases con el ambiente a través la sangre. De este modo el organismo obtiene oxígeno que es utilizado para oxidar los nutrientes obtenidos por el sistema digestivo.

- Sistema circulatorio: encargado de transportar nutrientes y oxígeno a las células del cuerpo y simultáneamente transportar elementos de desecho hasta los órganos del sistema excretor.

- Sistema excretor: encargado de eliminar los desechos de los alimentos. Los compuestos que no fueron digeridos en el intestino delgado llegan al intestino grueso donde se transforman en las heces las cuales son expulsadas por el ano. Por otra parte, el aparato urinario formado por los riñones y la vejiga urinaria funcionan para eliminar los desechos de la sangre a través de la orina.

Lunna [17]

Visual information from the retina is relayed through the lateral geniculate nucleus of the thalamus to the primary visual cortex — a thin sheet of tissue (less than one-tenth of an inch thick), a bit larger than a half-dollar, which is located in the occipital lobe in the back of the brain.
