Answer:
Deoxygenated blood enters the right atrium from the superior and inferior vena cava > The blood flows through the tricuspid valve into the right ventricle >From the right ventricle, the blood flows through the pulmonary valve into the pulmonary artery > The right and left pulmonary arteries carry deoxygenated blood to the right and left lungs for gas exchange > The blood releases carbon dioxide as waste and picks up a fresh supply of oxygen > The oxygenated blood flows through the pulmonary veins from the lungs into the left atrium > From the left atrium, the blood flows through the bicuspid, or mitral valve into the left ventricle > Left ventricular contraction forces blood through the aortic valve into the aorta for distribution to the systemic circulation
Explanation:
Answer:
The answer to the question: Electrical impulses or action potentials (AP) cannot propagate across a synaptic cleft. Instead, neurotransmitters are used to communicate at the synapse, and re-restablish the AP in the post-synaptic cell, would be, true.
Explanation:
Essentially, although the CNS, PNS and ANS (Central Nervous System, Peripheral Nervous System and Autonomic Nervous System) are electrical systems, that use the electricity generated through action potentials, that in turn, are created by the exchange of electrically charged ions from within and without the neuronal cells, these electrical impulses do not pass the pre-synaptic, and post-synaptic cleft. Instead, once an AP has reached the terminal end of the pre-synaptic neuron, neurotransmitters are released by this one, into the cleft, which are then taken up by the receptors present in the post-synaptic neuron. Depending on the type of transmitter released, there will be an inhibitory or excitatory effect. Then, with the transmitter attached, the post-synaptic neuron will depolarize and a new AP will be generated in the post-synaptic neuron, which will carry on. Messages, thus are transmitted that way between neurons, and also, between the nervous system and the organs they influence.
Answer:
In a patient underwent a single contrast upper GI series on Tuesday due to severe daily esophageal burning for six weeks, whose radiological diagnostic impression was Barrett's esophagus.
- <u><em>Day of encounter</em></u><em>: </em><em>Tuesday
</em>
- <u><em>Diagnosis Code</em></u><em>: K 22.7 </em><em>(CIE-10 code for Barrett's Esophagus)</em><em>
</em>
- <u><em>Procedure Code</em></u><em>: 74240</em>
Explanation:
Barrett's esophagus is a clinical condition characterized by a change in the esophageal epithelium due to repeated exposure to gastric juices, by reflux, or other mucosal irritants.
Corrosive agents are considered to produce a change in the epithelium called metaplasia, associated with symptoms of esophageal burning and pain.
The ICD-10 code for Barrett's esophagus is K 22.7.
The procedure, which consists of a radiological examination of the upper digestive tract with the use of barium contrast has a code of 74240, which describes this type of radiological examination.
