The human body is a compound and highly organised system which is formed of unique cells that act as a team to carry out the specific functions necessary for maintaining our daily life. Each organ in the human body is exceptionally vital. They protect us from harmful foreign objects such as bacteria and viruses. They let us do things like breathing, talking, movements, and our ability to smell. The circulatory system dispenses oxygen, carbon dioxide, nutrients, waste products, hormones and heat from the body to the tissues. It consists of the heart and blood vessels. The main function of the circulatory -system is to transport oxygen, hormones, and nutrients. The heart, which is the hardest working organ is located in the body’s thoracic …show more content…

They are connected by tissues and ligaments which enables motions within the human body. They are also responsible for the body’s overall movements. It sustains the body’s posture and temperature. It is the mechanical movements of the body. It includes of joints, bones and muscles. Interestingly, there are 206 bones in the human skeleton which consists of calcium, phosphorus and other minerals. For example, the rib cage protects our internal organs and plays an important part in breathing. Moreover, there are two types of muscles, involuntary and voluntary muscle that can be found in the heart and digestive system which functions automatically. On the other hand, voluntary muscle, are in our biceps and triceps which are under our control. The skull which is in the skeleton system protects and construction our face and the cavity of the …show more content…

The digestive systems consists of the mouth, oesophagus, stomach, liver, pancreas, small and large intestines and anus. The oral cavity is extremely vital in the process of chewing breaking down food. In addition, the saliva, which softs the food we chew comprises of enzymes that help with the process of digestion. The food that we consume goes down into the oesophagus which is basically a long tube that contains muscles which allows food down into the stomach. Both oesophagus and stomach use voluntary and involuntary movements. Our stomach contains acids known as hydrochloric acid, which helps dissolve and breaks down food. Within the digestive system is organ called liver. This organ filters out the blood that comes from our stomach. The liver is basically safe guard of all the other organs. It also purifies the chemicals that enter our body. Furthermore, the liver works closely with gallbladder, pancreas and intestines which help us with digestion and absorbing food. Underneath the liver is the gallbladder which aids in storing bile produced by the liver. In addition, the pancreas which is located behind the stomach is also connects to the small intestine (duodenum) and it contains a fluid known as pancreatic fluid. The major portion of digestion and observation takes place in the jejunum and ileum, which

The digestive system is responsible for chemically and mechanically breaking down food and includes organs such as, mouth, esophagus, stomach, small intestine, rectum, anus, and additional accessory organs. These organs all aid in the breakdown of food. Food is broken down mechanically by chewing and churning in the stomach, and chemically by acidic enzymes in the stomach and in the small intestine which receives enzymes from the pancreas that are specifically designed for the breakdown of nutrients. Once the food and nutrients are broken down, the excretory system removes whatever the body decides is waste by filtering blood in the nephrons of the kidneys and turning it into urine which is then collected in the bladder and removed from the body when the bladder is

The internal environment of the stomach has strong acids and active enzymes that trigger the occurrence of chemical reactions that begin to break down the ingested food. Thereafter, the process of absorption follows, whereas absorption of nutrients occurs in the intestinal tract. The process of absorption is short and is followed by excretion via the cloaca. Similarly, the liver and the pancreas assist in the process of excretion. Additionally, urinary and fecal waste travel through urinary passages and generative canals that connect to the cloaca and are emitted from the cloaca as jelly like, brown droppings.

First the food enters the mouth and then goes to the esophagus where it is pushed down to the first part of the stomach. The first part of the stomach is the cardiac stomach which holds chitinous teeth which grind up the food even more than it has been in the mouth. Then it goes to the pyloric region which is the second part of the stomach where nutrients are sucked out of the food.

All of the organs in the body maintain homeostasis. The circulatory system consisting of the heart and vessels is of vital importance. The heart pumps blood and other nutrients through the vessels to all of the other organs in the body. The heart, vessels, lungs all work together to maintain homeostasis.

First the food enters the mouth and that is where our child has a cleft palate. The salivary glands break down the food after being chewed by the teeth and makes it easier for the food to go to the pharynx where the oropharynx and laryngopharynx lead to the esophagus. In the esophagus the food goes down by a process called peristalsis towards the stomach. At the stomach, which is a C shaped bag basically that holds the food to digest with the acid that is in there. along the way the food passes the liver that produces bile for digestive purposes, and the gallbladder which stores that bile.

The skin is the protective covering of the body that prevents the invasion of microorganisms.

The separation of the small intestine allows for the duodenum which is the uppermost part where the most digestion occurs in which chyme from the stomach is combined with chemical secretions from the pancreas, liver and gallbladder to facilitate chemical digestion. The jejunum is where villi and microvilli get the most contact between organic molecules allows for the greatest amount of absorption of simple sugars, amino acids, etc into the bloodstream to be distributed throughout the body. The ileum is the final part of the small intestine and is similar in function to the jejunum, but is mostly is to get the final absorption of vitamins before it enters the large intestine. The liver produces bile, which is then stored in the gallbladder, which separates fat globules into smaller segments to increase surface area, thus allowing for an easier method of digestion. The pancreas has an exocrine gland in which it releases digestive juices through a duct, and these juices consist of bicarbonate ions which are used to neutralize acid in the stomach, allowing for digestion enzymes that only work in lower Ph levels to

The adrenals are known for making the hormone adrenaline but also, they make the corticosteroids which affect your metabolism and sexual function. The pancreas is part of the the digestive system and the endocrine system. It makes the hormones insulin and glucagon. These help ensure you have the right amount of sugar in your bloodstream and your cells. If you don 't make any insulin, which is the case for people with type one diabetes, your blood sugar levels can get dangerously high and if the body makes some insulin but not enough, that is type two diabetes.

The digestive system is located around the stomach area. Along with the digestive system, many other organ systems all work together to create an organism. An example of this would be if a person eats a sandwich and then goes for a run. During the run, the circulatory system helps the body breathe, the muscle system helps the bones move, and all the while the digestive system digests the food. Later on, the excretory system gets rid of the waste, or food that the body can’t use for nourishment.
