Langerhans cells are dendritic cells (antigen-presenting immune cells) of the skin, and contain organelles called Birbeck granules. They are present in all layers of the epidermis and are most prominent in the stratum spinosum.
Four bones of the skull contain paired air spaces called the paranasal sinuses that help to lighten the heavy load of the head.
<h3>What is Paranasal Sinus?</h3>
The paranasal sinuses are air-filled, bony spaces located next to the nasal passages in the face bones of the skull. They grow via slowly expanding pneumatized cells that erupt from the nasal cavity. The term is typically used in everyday speech to refer to the hollow, air-filled spaces in front of the human skull. There are four pairs of sinuses in humans. There are now eight sinuses in all. These four pairs of sinuses are together referred to as paranasal sinuses since they are all joined to the nasal cavity.

Answer:
The best answer to the question: A nurse is monitoring the laboratory values of a client who is receiving heparin. Which of the following values should a nurse report to the provider? would be: D: aPTT of 50 seconds.
Explanation:
Unlike Warfarin and the low-molecular weight heparin, medically speaking, the one diagnostic test that is still being used as a measure of heparin´s therapeutic achievements in a patient with a coagulopathy, is the activated partial thromboplastin time aPTT. Although the measurement in seconds, will depend on the laboratory that is doing the measuring, and despite scientific evidence that points to the fact that aPTT is not the most accurate of laboratory measurements for a patient with heparin, it is still being used today and still is the leading laboratory test for these types of patients.
Answer:
Patients who suffer from respiratory pathologies, generally present an increase in fluid in the alveoli, where they produce the gas exchange, that is why if we put the patient to bed completely, the gas exchange surface will be less, because the liquid that presents by the pulmonary emphysema is dispersed in more alveoli and therefore the difficulty of breathing is greater.
The ideal position then in this type of patient, where the problem is in the respiratory system, in the position of approximately 130 degrees, or an intermediate position between 180 and 90 degrees, since in this way the upper limb will not be at the same Height than the lower limb, the emphysema fluid does not disperse through the alveoli on a larger surface, but on a smaller surface, and thus the patient will be able to breathe better, and improve their gas exchange capacity.
Explanation:
The greater the occupied alveolar surface, the less capacity for gas exchange and therefore greater difficulty in breathing ... This would happen in patients who are fully reclined, that is, at 180 degrees.
If we position it well, between 90 and 180, approximately 130 degrees, less alveolar surface occupied by the fluid of the emphysema, greater gas exchange and therefore better breathing.
