kidney

The kidneys are two bean-shaped organs found on the left and right sides of the body in vertebrates. They are located at the back of the abdominal cavity in the retroperitoneal space. In adults they are about 11 centimetres (4.3 in) in length. They receive blood from the paired renal arteries; blood exits into the paired renal veins. Each kidney is attached to a ureter, a tube that carries excreted urine to the bladder.
Abdominal Cavity - The abdominal cavity is a large body cavity in humans.
 and many other animals that contains many organs. It is a part of the abdominopelvic cavity

alimentary canal

It is a group of organs in the body which work together to digest food. Digestion is the process by which our body breaks down food into substances we can take in (absorb) and use. Food travels through the alimentary canal which starts at mouth and ends at the anus. The alimentary canal

salibary gland

The salivary glands in mammals are exocrine glandsglands with ducts, that produce saliva, which is composed of several components including amylase, a digestive enzyme that breaks down starch into maltose and glucose. In humans and some other mammals the secretion is alpha-amylase, also known as ptyalin.

Digestive system

The human digestive system consists of the gastrointestinal tract plus the accessory organs of digestion (the tonguesalivary glandspancreasliver, and gallbladder). In this system, the process of digestion has many stages, the first of which starts in the mouth. Digestion involves the breakdown of food into smaller and smaller components, until they can be absorbed and assimilated into the body.

human heart





The heart is a muscular organ in most animals, which pumps blood through the blood vesselsof the circulatory system Blood provides the body with oxygen and nutrients, as well as assists in the removal of metabolic wastes. In humans, the heart is located between the lungs, in the middle compartment of the chest.
 Cardiovascular diseases (CVD) are the most common cause of death globally as of 2008, accounting for 30% of deaths. Of these more than three quarters are a result of coronary artery disease and stroke.Risk factors include: smoking, being overweight, little exercise, high cholesterol, high blood pressure, and poorly controlled diabetes, among others. Cardiovascular diseases frequently do not have symptoms or may cause chest pain or shortness of breath. Diagnosis of heart disease is often done by the taking of a medical history, listening to the heart-sounds with a stethoscope, ECG, and ultrasound.Specialists who focus on diseases of the heart are called cardiologists, although many specialties of medicine may be involved in treatment.

pancreas

The pancreas /ˈpæŋkriəs/ is a glandular organ in the digestive system and endocrine system of vertebrates. In humans, it is located in the abdominal cavity behind the stomach. It is an endocrine gland producing several important hormones, including insulinglucagonsomatostatin, and pancreatic polypeptide, all of which circulate in the blood
As part of embryonic development, the pancreas forms from the embryonic foregut and is therefore of endodermal origin. Pancreatic development begins with the formation of a ventral and a dorsal pancreatic bud. Each structure communicates with the foregut through a duct. The dorsal pancreatic bud forms the head, neck, body, and tail, whereas the ventral pancreatic bud forms the uncinate process

diabetes

Diabetes is a disease that occurs when your blood glucose, also called blood sugar, is too high. Blood glucose is your main source of energy and comes from the food you eat. Insulin, a hormone made by the pancreas, helps glucose from food get into your cells to be used for energy.

Diabetes, often referred to by doctors as diabetes mellitus, describes a group of metabolic diseases in which the person has high blood glucose (blood sugar), either because insulin production is inadequate, or because the body's cells do not respond properly to insulin, or both

Type 1 diabetes is caused by the immune system destroying the cells in the pancreas that make insulin. This causes diabetes by leaving the body without enough insulin to function normally. This is called an autoimmune reaction, or autoimmune cause, because the body is attacking itself.

Causes of Diabetes

There is no one common diabetes cause
There is no one common diabetes cause
Diabetes causes vary depending on your genetic makeup, family history, ethnicity, health and environmental factors.
There is no common diabetes cause that fits every type of diabetes.
The reason there is no defined diabetes cause is because the causes of diabetes vary depending on the individual and the type.
For instance; the causes of type 1 diabetes vary considerably from the causes of gestational diabetes.
Similarly, the causes of type 2 diabetes are distinct from the causes of type 1 diabetes. 

Type 1 diabetes causes

Type 1 diabetes is caused by the immune system destroying the cells in the pancreas that make insulin. This causes diabetes by leaving the body without enough insulin to function normally.

This is called an autoimmune reaction, or autoimmune cause, because the body is attacking itself.
There is no specific diabetes causes, but the following triggers may be involved:
  • Viral or bacterial infection
  • Chemical toxins within food
  • Unidentified component causing autoimmune reaction
Underlying genetic disposition may also be a type 1 diabetes cause.

Type 2 diabetes causes

Type 2 diabetes causes are usually multifactorial - more than one diabetes cause is involved. Often, the most overwhelming factor is a family history of type 2 diabetes.
This is the most likely type 2 diabetes cause.
There are a variety of risk factors for type 2 diabetes, any or all of which increase the chances of developing the condition.
These include: 
  • Obesity
  • Living a sedentary lifestyle
  • Increasing age
  • Bad diet
  • Death rate due to diabetes
Other type 2 diabetes causes such as pregnancy or illness can be type 2 diabetes risk factors

The global prevalence of diabetes* among adults over 18 years of age has risen from 4.7% in 1980 to 8.5% in 2014 (1). ... Diabetes is a major cause of blindness, kidney failure, heart attacks, stroke and lower limb amputation. In 2015, an estimated 1.6 million deaths were directly caused by diabetes.
