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
