The substance secreted by the kidneys that helps control blood pressure via vasodilation is called nitric oxide (NO).

Nitric oxide is a vasodilator, which means that it relaxes the smooth muscles in the blood vessels, leading to an increase in their diameter and a decrease in blood pressure. Nitric oxide is produced in the endothelial cells that line the blood vessels, and its production is regulated by several factors, including shear stress and various hormonal and chemical signals.

The kidneys play an important role in regulating blood pressure by controlling the amount of sodium and water in the body. When the kidneys sense low blood pressure, they release renin, which initiates a cascade of events that ultimately leads to the production of angiotensin II, a potent vasoconstrictor. However, the kidneys also release nitric oxide to counteract the vasoconstrictor effects of angiotensin II and help maintain blood pressure within a normal range.

Sympathetic effect: Heart rate increases, force of heart contraction increases, diameter of bronchioles decreases, diameter of pupils dilates, diameter of skin and muscle blood vessels constrict, diameter of blood vessels to the kidney constrict.

Parasympathetic effect: Heart rate decreases, force of heart contraction decreases, diameter of bronchioles increases, diameter of pupils constricts, gastrointestinal motility and secretions increase, diameter of skin and muscle blood vessels dilate, diameter of blood vessels to the kidney dilate.

During the incident, the dogs experience a fight or flight response, which is mediated by the sympathetic nervous system. The larger dog’s posturing and aggressive behavior cause the smaller dog to respond in a similar manner, resulting in an escalation of the fight response. The sympathetic nervous system increases heart rate, force of heart contraction, dilates pupils and constricts blood vessels in the skin and muscles, and inhibits gastrointestinal motility, secretions, and blood flow.

After the smaller dog rolls over and shows its belly, the incident de-escalates, and the dogs experience a calming effect mediated by the parasympathetic nervous system. The parasympathetic nervous system decreases heart rate, force of heart contraction, constricts bronchioles, constricts pupils and dilates blood vessels in the skin and muscles, and stimulates gastrointestinal motility, secretions, and blood flow.

The return form Golgi to ER processes occurs via the mechanisms described as retrograde transport.

There are several mechanisms by which this process occurs:

COPI-coated vesicles: The COPI (coat protein complex I) coat is a protein complex that forms a vesicle around cargo molecules, allowing them to be transported from the Golgi to the ER. COPI-coated vesicles are responsible for the majority of retrograde transport from the Golgi to the ER.

Retromer complex: The retromer complex is a protein complex that binds to cargo molecules and directs them to the trans-Golgi network (TGN), where they can be sorted into COPI-coated vesicles for retrograde transport to the ER.

KDEL receptor: The KDEL receptor binds to these proteins and directs them to COPI-coated vesicles for retrograde transport to the ER.

Auto-PEEP makes triggering the ventilator more difficult for a patient.

Auto-PEEP, also known as intrinsic positive end-expiratory pressure, occurs when there is incomplete exhalation before the next breath begins during mechanical ventilation. This leads to an increased level of positive pressure in the airways at the end of exhalation. Auto-PEEP can occur due to air trapping, increased airway resistance, or inadequate expiratory time.

Auto-PEEP interferes with triggering the ventilator because the patient's respiratory efforts and the ventilator's triggering mechanism may not be synchronized. The increased positive pressure in the airways caused by auto-PEEP makes it harder for the patient to generate an adequate drop in airway pressure to initiate a breath. As a result, the patient's respiratory efforts may not be detected by the ventilator, leading to ineffective or delayed triggering.

In addition, auto-PEEP can also cause patient-ventilator dyssynchrony, where the ventilator delivers a breath before the patient has completed exhalation. This can lead to increased work of breathing, discomfort, and patient fatigue.

Managing auto-PEEP involves identifying the underlying causes, optimizing ventilator settings, and ensuring adequate expiratory time to allow for complete exhalation. Proper monitoring and adjustment of ventilator parameters can help improve patient-ventilator synchrony and reduce the adverse effects associated with auto-PEEP.
