Answer:

The correct answer will be option B-left atrium.

The coronary circulation is the circulation of blood and nutrients to the myocardium of the heart on both sides.

The coronary system consists of coronary arteries and coronary sinus(vein) in which coronary arteries arise from the main artery of the circulatory system called aorta.

Describe how the care technique of adequate posture for bed ridden clients can impact parts of the respiratory system. Use corre
romanna [79]

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.
