 * __ Human Digestive System __**
 * When it comes to the human digestive system, the process begins with the mouth. We break down our food partially by chewing and the chemical action of salivary enzymes which are produced by salivary glands. After food has been swallowed it enters the esophagus. The esophagus is a long tube connected to the mouth and stomach. The esophagus uses wave-like muscle movements to push food into the stomach from the throat. Once the food exits the esophagus, it then enters the stomach. The stomach churns the food and bathes it in gastric acid. The food in the stomach that has been partially digested is then mixed with stomach acids called chyme. The food enters the duodenum, which is the first part of the small intestine. **
 * After going through the duedenum, food then passes through the jejunum and the ileum of the small intestine. Bile, pancreatic enzymes, and other digestive enzymes that are produced in the small intestine help the breaking down of food. The nutrients are broken down small enough to pass through the lining of the small intestine and into the blood. This process is called diffusion. The nutrients are then carried to the liver and other body parts to be processed, stored, and delivered. The liver stores some nutrients and changes them from one form to another, and releases them into the blood according to the activities and needs of the body. The function of the gall bladder is to store bile which is produced in the liver. As food enters the small intestine, bile flows from the gall bladder along the bile duct into the intestine. The gall bladder helps digest fatty foods and also contains waste for removal. The functon of the pancreas is that forms enzymes that help in the digestion of carbohydrates, fats, and proteins in the small intestine. After the food has passed through the small intestine, it passes through the large intestine. **** Some of the water and electrolytes (like sodium),are removed from the food in the large intestine. The remains are formed into brown semin, solid feces, ready to be removed from the body. The feces are finally squeezed through a ring of muscle, the anus, and out of the body. **


 * __Panda Bear Digestive System__ **

**The mouth is the first step of breaking down the food. It mixes the food with saliva and the teeth break the food down so it can be digested in the stomach. The salivary gland gives off saliva to mix wih the food to start the digestive process, making it easier for the next step of digestion. The esophagus transports the food from the mouth to the stomach. Their stomach is bigger. They have a digestive system of a carnivore so their stomach is larger. The food is digested and sent to the next steps small intestine.**



__** Human Excretory System **__
 * Liquid waste is removed from the body through kidneys. The kidneys filter the wastes from the blood, forming a liquid called urine. The kidneys funnel the urine into the bladder along the two separate tubes called ureters. The bladder stores the urine until muscular contractions force the urine out of the body through the urethra. Urine is removed through urination. **

__**Human Respiratory System**__
 * Oxygen enters the respiratory system through the mouth and nose. The oxygen then goes through the larynx and the trachea which is the tube that enters the chest cavity. The trachea splits into smaller tubes that are called bronchi. They divide again forming the bronchial tubes. These tubes lead directly to the lungs which divide into smaller tubes that connect to tiny sacs called alveoli. When the diaphragm relaxes, CO2 is pumped out of the lungs. **




 * __ Human Circulatory System __**
 * The heart has four chambers, two atria and two ventricles. The right atrium receives oxygen- poor blood from the body and pumps it into the right ventricles. The right ventricle pumps the oxygen and poor blood to the lungs. The left atrium receives oxygen- rich blood from the lungs and pumps it to the left ventricle. The left ventricle pumps the oxygen-rich blood to the body. The blood vessels provide two important means of measuring vital health statistics; pulse and blood pressure. The arteries deliver oxygen- rich blood to the capillaries where the actual exchange of oxygen and carbon dioxide occurs. The capillaries then deliver the waste- rich blood to theveins to transport back to the lungs and heart. **



**__Panda Circulatory System__**
 * Pandas and humans have similar circulatory systems. They breathe through their mouth and nose. The normal blood pressure of a Panda will range between 140/88mmHg ang 160/90mmHg. **




 * __ Human Nervous System __**
 * Cerebellum controls balance, posture, and coordination. The cerebrum and cerebellum are connected to the spinal cord by brain stem. The olfactory bulb are receptors for smell. The medulla oblongata contains the control centers for swallowing,breathing,digestion, and heartbeat. **

__**Human Locomotion**__
 * Cartilage is flexible,fibrous, and elastic. Tendons attach muscles to bones. Joints attach bone to bone. The axial skeleton consists of the skull, vertebral column, and rib cage. The appendicular skeleton contains the bones of the appendages, and the pectoral and pelvis appendages . **
