Digestive System

it plays an important role because the stones wind up the birds gizzard, a pace which helps to grind the birds food, before it reaches the intestines.

The skeletal system stores the excess calcium that the digestive system breaks down from food. The body does not need all of the calcium that it gets from food, so it stores what is not needed within the bones until the body has a use for it. This is what keeps your bones hard and strong.

No, the digestive system is an organ system made up of organs, which in turn are made up of tissues.

the mouth,pharnyx/throat, esophagus,stomach,small intestine,large intestine,rectum,and anus

you can include the liver,gallbladder,salivary glands,and pancreas in there but food doesnt pass threw it

through the esophagus to the stomach and the rest of the intestional tract.

The mechanical shredding and crushing of food (together with the mixing in of salivary amylase to start digestion) is mastication.

The circulatory system is big and complex. The basics are that generally arteries convey oxygenated blood, while veins carry deoxygenated blood. The left side of the pig conveys oxygenated blood and the right conveys deoxygenated. The only exception to the artery vein rule is in the pulmonary artery and vein. The pulmonary vein, in this case, conveys oxygenated blood to the left atrium away from the lungs. The pulmonary artery then carries deoxygenated blood away from the left ventricle to the lungs. To start the right atrium conveys blood from the superior vena cava to the right ventricle. The left atrium conveys blood from pulmonary vein to left ventricle. THe right ventricle conveys blood from the right atrium to the pulmonary artery. The left ventricle gives blood from the left atrium to the aorta. The coronary artery is the artery snaking down the middle of the heart conveying oxygenated blood around the heart. The aorta transports blood from the left ventricle to the arteries. The superior vena cava conveys deoxygenated blood from the upper body to the right atrium. The inferior vena cava conveys deoxygenated blood from the lower body to the right atrium. The common carotid arteries convey oxygenated blood from heart to head. The external and internal jugular veins convey deoxygenated blood from head to heart. The subscapular arteries give blood to the shoulders and the axillary give blood to the armpits. Renal arteries convey oxygenated blood from the aorta to kidneys. The renal veins convey deoxygenated blood from the kidneys to the inferior vena cava. Femoral arteries give blood to legs while iliac arteries and veins give blood to genitals. THe ductus arteriosis, the webbing above the heart gives blood o the aorta from the pulmonary artery. The umbilical artery is simply used for blood exchange when the mother during early develoopment of the pig feti.

Another name is the liver, the large intestine is not another name for colon. Whenever someone is diagnosed with colon cancer it is because the liver isn't producing bile and filtering toxins.

that remedy is called antacid and is helps with indigestion because you can the remedy 'antacid'. antacid contains weak bases.bases neutralize acid by reacting with them to form water and a salt. the reason the weak bases are used instead of strong bases is because strong bases would neutralize to much acid and would most likely kill you.

Yes. If liver malfunctions, you get hapatitis, by which the whole digestive system is impaired.

The liver is the organ in the body that cleans poisons out of the system. Red blood cells and Kupffer cells are formed in the liver. Red blood cells carry oxygen and Kupffer cells eliminate microorganisms.

Peristalsis is the muscular action that causes material to travel (normally) through the gastro-intestinal system.

Reverse peristalsis is the reverse :

that is from the colon to the small intestines to the stomach to the esophagus to the mouth - and then vomited out.

Secretes bicarbonate to make the acid alkaline

It takes around 62 hours for water to pass through, but if its a slightly thicker, liquid it takes around 46 hours.

(The thinner the substance, the longer it takes).

Once food passes out of the stomach, enzymes get to work on the nutrients in the small intestine, breaking them into smaller products. It is also in the small intestine where substances are absorbed into the bloodstream. This absorption takes place in tiny, finger-like structures called villi. These line the walls of the intestine, and are ideal for the diffusion and active transport of molecules.

NO!

the stucture of the circulatory system is to the circulatory - or cardiovascular - system carries blood that is low in oxygen away from the heart to the lungs via veins, where oxygen levels are restored through the air which we breath in; once oxygenated, this blood is then carried throughout the body via arteries, keeping our organs and tissue alive.

It consists of the heart, which powers the whole process; the veins and arteries; and capillaries, which deliver oxgen to tissue at the cellular level.

The process is called peristalsis. It is the rhythmic contraction of smooth muscle cells in the lining walls of your gastrointestinal epithelium. It occurs when you are awake, asleep, etc. and is sped up or slowed down by your nervous and endocrine (hormones) systems. Basically, your internal organs give lots of little squeezes that makes food/what used to be food move along.

the bile duct

chemical digestion takes place in the small intestine large intestine,mouth and stomach. Nutrients are absorbed in the small intestine and minerals in the large intestine.

No. On some individuals, the appendix is very small or may be merged into the surrounding tissue during growth. In a rare condition known as situs inversus, the appendix may be on the left side rather than the right side of the abdomen.
