You have just delivered a premature baby. Your assessment reveals that he is breathing adequately; however, his heart rate is 90
s2008m [1.1K]

Answer:

The answer is letter B, keep him warm and ventilate with BVM.

Explanation:

In order to know more about the answer, let's check out the meaning of "Premature Baby" first.

Premature Baby- a baby born through premature birth <em>(fewer than 37 weeks).</em>  Babies are normally born at the usual <em>40 weeks.</em> Health problems may occur with premature babies, thus it is very important to monitor them.  

In the situation above, the premature baby's heart rate is only 90 beats/min. <em>A resting heart rate for a newborn infant is 130-150 beats per minute. </em>This means that the baby above has a slow heart rate. In order to increase the hear rate, it is important to keep the baby warm and to ventilate with a "Bag Valve Mask" (BVM). <u><em>An increase in internal temperature increases the heart rate. Increasing ventilation will also help increase the heart rate. </em></u>

<u><em>Remember: </em></u>Inhalation increases the heart rate.

The excretory system helps the respiratory system by
Leto [7]

Answer:

The excretory system helps the respiratory system by removing carbon dioxide that is produced during respiration (third option).

Explanation:

The lungs are in charge of the breathing process, being the main organ of the respiratory system. Each lung is considered an excretory organ —belonging to the excretory system— since it is capable of eliminating the carbon dioxide (CO₂) produced by the metabolism during expiration.

As a result of the gaseous exchange, the oxygen entering the lungs through the inhaled air passes into the blood, while the CO₂ is removed from the blood. This CO₂ is removed during expiration, which makes the lungs part of the excretory system.

The other options are not correct because:

  • <em>The excretory system does </em><u><em>not introduce more oxygen into the lungs</em></u><em>. </em>
  • <em>The </em><u><em>circulation of blood in and out of the lungs</em></u><em> is a function of the circulatory system. </em>
  • <u><em>Urine is not produced by breathing</em></u><em>.</em>

In ____________ , signals pass through a cell junction from one cell to adjacent cells. membrane-bound signals bind to receptors
harina [27]
In cell-cell contact , signals pass through a cell junction from one cell to adjacent cells.
Membrane-bound signals bind to receptors on adjacent cells in the process of paracrine signalling.
An example of autocrine signalling is when cells release signals that affect themselves and nearby target cells.
 In synaptic signalling cells release signals that affect nearby target cells. Cells release signals that travel long distances to affect target cells during endocrine signalling.
