Explanation:

The entire cardiac cycle is as follows:

  1. Deoxygenated blood enters the right ventricle from the superior and inferior vena cava.
  2. The right atrium pumps the deoxygenated blood to the right ventricle.
  3. From the right ventricle, the deoxygenated blood moves to the lungs via the pulmonary artery.
  4. After gaseous exchange, the oxygenated blood returns to the heart into the left atrium via the pulmonary vein.
  5. From the left atrium, blood moves to the left ventricle.
  6. Oxygenated blood is pumped by the left ventricle into the aorta which supplies blood to all parts of the body.
  7. Deoxygenated blood, collected from the body again enters into the right atrium via the vana cava.

Papessa [141]

Answer:

My pretest behaviors were triggered by the sympathetic nervous system, while my body returned to its normal state by the way of the parasympathetic nervous system, after the test.

Explanation:

The sympathetic nervous system and the parasympathetic nervous system are part of the autonomic nervous system. The main function of the autonomic nervous system is to regulate the heart, kidneys, and liver which are not under voluntary control. The regulation of the body’s unconscious actions is executed through the sympathetic and the parasympathetic nervous system.

Upon exposure to stressors or threats, the sympathetic nervous system is triggered. Epinephrine and norepinephrine are then released, causing acceleration of the heart, constriction of blood vessels, increase in blood pressure, profuse sweating and other related responses against stress. The sympathetic nervous system controls all these involuntary responses that could be termed “fight-flight-or-freeze” response.

On the other hand, the parasympathetic nervous system initiates what is termed “rest and digest” response, which occurs immediately after the “fight-flight-or-freeze” phase response to stress is over. The body is returned to its normal state by the parasympathetic nervous system. The parasympathetic nervous system releases acetylcholine, which regulates the function of the body during a period of rest or recuperation.

A client has been diagnosed with gram-negative pneumonia. Knowing this bacteria has a lipopolysaccharide endotoxin on the outer
agasfer [191]

Answer:

The options

A)Damage to cellular mitochondria

B)Increased ATP levels

C)Activation of the p53 protein

D)Apoptosis

The CORRECT ANSWER IS D

D)Apoptosis

Explanation:

The extrinsic pathway of apoptosis includes extracellular signaling proteins which adhere to cell surface molecules known aa death receptors which in turn activates apoptosis.

The aftermath activates endonucleases prompting division of DNA and ultimately cell death.

Apart from the TNF and Fas ligand, primary signaling molecules also promotes the extrinsic pathway, examples of such are the TNF-related apoptosis-inducing ligand (TRAIL); the cytokineinterleukin-1 (IL-1); and lipopolysaccharide (LPS), the endotoxin located in the outer cell membrane of gram-negative bacteria while the activation of the p53 protein, and decreased ATP levels in the intrinsic pathway results in DNA damage.
