What happens at a cellular level during organ rejection?

Medicine

Organ rejection takes place when your body is subjected to a new organ which is a foreign object and attacks it.

<h3>What do you mean by Graft rejection?</h3>

Graft rejection may be defined as a process in which a transplant recipient's immune system attacks the transplanted organ or tissue.

Xenograft shows high rejection. This is because it involves the transplantation between genetically distinct members of different species.

The process of organ rejection is initiated by T cells which perform the role of the recognization of a transplanted organ.

If these T cells are activated, it may lead to organ rejection by undergoing clonal expansion, and differentiation of the effector cells, which together lead to the obliteration of the tissues.

Therefore, organ rejection takes place when your body is subjected to a new organ which is a foreign object, and attacks it.

<h3>The top global leading causes of death in communicable diseases</h3>

Communicable diseases are those diseases that can be transmitted from one person to another through close contact or transfer of body fluids from an infected individual.

According to World Health Organizations, the five communicable diseases that has caused highest death rates are :

  • Lower respiratory infections: This has caused about 3.4 million deaths.

  • HIV/AIDS: This has caused about 2.6 million deaths.

  • Diarrheal diseases: this has caused about 1.8 million deaths.

  • Tuberculosis(TB): This has caused about 1.6 million deaths. and

  • Malaria: This has caused about 1.1 million deaths.

Is There Such A Thing As Too Much THC?
Ilia_Sergeevich [38]

Answer:

A fatal overdose is unlikely, but that doesn’t mean marijuana is harmless. The signs of using too much marijuana are similar to the typical effects of using marijuana but more severe. These signs may include extreme confusion, anxiety, paranoia, panic, fast heart rate, delusions or hallucinations, increased blood pressure, and severe nausea or vomiting. In some cases, these reactions can lead to unintentional injury such as a motor vehicle crash, fall, or poisoning.

The movement of ions through their channels require a discharge of the capacitance.
Nesterboy [21]

Answer:

The answer to the question: The movement of ions through their channels require a discharge of the capacitance, is, true.

Explanation:

In order for cells, muscular and neuronal, to perform their activities, they need to generate action potentials, that will permit these activities. In order for an action potential to happen, a cell´s membrance must be charged, or rather, its polarity must be changed, so that the cell can be charged and then fire. Usually, cells remain in a resting membrane state, in which, the extracellular matrix remains positive, while the intracellular space remains positive, due to ion, and anion presence in either. In order for the action potential to happen, these polarities are reversed through a series of steps in which ions, particularly potassium and sodium, sometimes calcium, will enter and exit the cell´s membrane to change this polarity. But in order for this process to take place, first a current, or stimulation, must motivate the cell to start the process. The capacitance is the capability of a cell to be ready to be activated or de-activated when stimulated, meaning, to be charged and discharged, when necessary. In order for this capacitance to permit the process of action potential formation, it needs to be discharged first, and this is done through the stimulus, which orders the cell´s membrane to initiate depolarization by opening up the ion channels. This is why the answer is true.
