-The stomach is a muscular organ located on the left side of the upper abdomen. The stomach receives food from the esophagus. As food reaches the end of the esophagus, it enters the stomach through a muscular valve called the lower esophageal sphincter. The stomach secretes acid and enzymes that digest food.
CARDIAC
-The cardiovascular system supplies body's organs with oxygen and nutrients so organs can do their jobs.Blood vessels also carry carbon dioxide and other waste away for disposal.
MOUTH
-Mouth is the opening in the lower part of the human face, surrounded by the lips, through which food is taken in and from which speech and other sounds are emitted.
SKELETON
-Skeleton is an internal or external framework of bone, cartilage, or other rigid material supporting or containing the body of an animal or plan.
KIDNEY
-The kidneys are a pair of bean-shaped organs on either side of your spine, below your ribs and behind your belly. Each kidney is about 4 or 5 inches long, roughly the size of a large fist. The kidneys' job is to filter your blood.
HEART
-Heart is a hollow muscular organ that pumps the blood through the circulatory system by rhythmic contraction and dilation. In vertebrates there may be up to four chambers (as in humans), with two atria and two ventricles.
SKULL
-Skull is the skeleton of the head of a vertebrate forming a bony or cartilaginous case that encloses and protects the brain and chief sense organs and supports the jaws.
BRAIN
-Brain is an organ of soft nervous tissue contained in the skull of vertebrates, functioning as the coordinating center of sensation and intellectual and nervous activity.
BONES
-A bone is a rigid tissue that constitutes part of the vertebrate skeleton in animals. Bones protect the various organs of the body, produce red and white blood cells, store minerals, provide structure and support for the body, and enable mobility.
LUNGS
-Each of the pairs of organs found inside the rib cage, consisting of elastic sacs with air-drawn branching passages, so that oxygen can flow into the blood and eliminate carbon dioxide. Although similar structures are present in some other animal groups, lungs are characteristic of vertebrates other than fish.
