What acts as alarm signals to activate the body 's immune system by stimulating helper t-cells​

Medicine
1 answer:
solong [7]3 years ago
7 0

Answer:

Helper T cells are arguably the most important cells in adaptive immunity, as they are required for almost all adaptive immune responses. They not only help activate B cells to secrete antibodies and macrophages to destroy ingested microbes, but they also help activate cytotoxic T cells to kill infected target cells. As dramatically demonstrated in AIDS patients, without helper T cells we cannot defend ourselves even against many microbes that are normally harmless.

Helper T cells themselves, however, can only function when activated to become effector cells. They are activated on the surface of antigen-presenting cells, which mature during the innate immune responses triggered by an infection. The innate responses also dictate what kind of effector cell a helper T cell will develop into and thereby determine the nature of the adaptive immune response elicited.

In this final section, we discuss the multiple signals that help activate a T cell and how a helper T cell, once activated to become an effector cell, helps activate other cells. We also consider how innate immune responses determine the nature of adaptive responses by stimulating helper T cells to differentiate into either TH1 or TH2 effector cells.

An unconscious adult victim is gasping for breath and having difficulty breathing. the scene is safe and help has been called. n
NISA [10]

An unconscious adult victim is gasping for breath and having difficulty breathing. The scene is safe and help has been called. Next you should use the head tilt chin lift procedure.

An unconscious patient is at risk of blocking their airway and suffocating. The main reason for this occurring is due to the tongue. An unconscious patient loses all their muscular tone, and this includes the tongue! The tongue can fall back and block the airway.

This situation is an emergency – without a supply of oxygen reaching the lungs, the patient will suffocate in a matter of minutes.

In CPR, we use the head-tilt, chin-lift method to open the airway.

How to Perform a Head-tilt Chin-lift :

  1. Kneel next to the patient’s head
  2. Place one hand on the patient’s forehead and tilt the head gently backward
  3. Place two fingers under the bony part of their chin and lift the chin vertically upwards
  4. Take care not to place any pressure on the soft part of the neck as this could obstruct the airway

If a cervical spine injury is suspected, then the modified jaw thrust would be used in place of "head-tilt, chin-lift". The jaw thrust is a technique used on patients with a suspected spinal injury and is used on a supine patient.

Fofino [41]

Answer:

The meaning of life is to help others and boost others but still do that for yourself and make yourself time if not the balance needed in life will be disrupted and you will turn either to selfless or selfish

Explanation:

Here is an example

If I were to help 30 people move in there new houses but then not be able to move into mine helping them it will turn into a spiral of selflessness

If I were to say no when someone wanted the last of the ice cream flavor I wanted I would turn selfish and the other people would always be upset they don't get the flavor they want this will start me to think everyone should and will give me want I want

So you see the meaning of life is balance no money love or anything else
