1 answer:

6 0

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.

Angelina_Jolie [31]

Electrical burns usually follow an internal path.

<h3>What are the damages caused by a lightning strike on humans?</h3>

While only 10% of those who are struck by lightning die, many of the 90% who do survive have long-term difficulties.

Depending on the sort of lightning hit and the amount of electricity passing through the body, several effects might result from a lightning strike.

Lightning can destroy tissue, leave deep wounds, and result in skin burns. Additionally, the electrical current may result in a sort of scaring called Lichtenberg figures (branching electric discharges). Unusual fractal patterns emerge as a result of blood vessel destruction that occurs when the lightning current passes through the body to describe this sort of scarring.

A lightning strike can halt the heart, leading to cardiac arrest. It may also result in pulmonary edema and arrhythmias.

Brain injury and a variety of neurological disorders may be brought on by lightning strikes. A person may suffer from spinal cord injuries, go into a coma, feel pain, numbness, or weakness in their limbs, or have sleep or memory issues.

A lightning strike could harm the ear and impair hearing. Additionally, it may result in blindness, corneal damage, and vertigo.

likoan [24]

Answer:

We begins to digest the carbohydrates the minute the food goes to our mouth. The saliva which is secreted from our salivary glands moisten up the food when it is chewed. Salivary amylase is present in our saliva which begins the breaking process of sugars in the carbohydrates when we are eating. It is also referred to as ptyalin. Salivary glands are exocrine glands which makes saliva through a ductory system.Humans have three major paired salivary glands ( parotid, submandibular & sublingual)as well as hundreds of minor salivary glands. Minor salivary glands on the tongue leads to the secretion of amylase. Parotid gland assemble purely serous saliva. The other major salivary glands produce mixed saliva ( serous plus mucous). Another types of serous fluid produced by two layered serous membranes which lines the serous cavity.
