“Just sit right back and you’ll hear a tale, a tale of a fateful trip.” These lines from the television show, Gilligan’s Island kept running through my mind when Ms. Saunders announced her plans for our group of four to go to our own private island for an extended stay of ten years. I did feel as though I would be walking in Gilligan’s shoes. Ms. Saunders had convinced me, that like Gilligan, our group would survive with good planning, adequate resources and proper functioning body systems. Due to the long stay on the island, our crew must be prepared to use resources carefully and wisely. Most importantly, we must take the plant and animal life that will provide the resources. As for plant life, our group will pack provisions to plant corn, …show more content…
The digestive system has many functions that allow people to live out their daily lives including the production of energy through nutrients in a functioning digestive system. The first function of the digestive system is the ingestion process. Ingestion is the intake of food performed by the mouth. Then, the mouth and stomach are responsible for storing the food until digestion. After ingestion, the digestive system secretes fluids, in order to soften the food and protect and lubricate internal organs, through a means called secretion. The food is then sent through a procedure of mixing and movement. Mixing and movement move the food to the intestines for digestion. Digestion is the most known function of the digestive system. Food is turned into chemicals and broken down into building blocks. When the digestive system has its building blocks, absorption takes place in the small intestines. The small intestine contains microscopic blood and lymphatic cells which carry the chemicals all over the human body. Once the chemicals are dispersed, the final process of the digestive system takes place. The overall progression is called excretion. Defecation is the process within excretion. Defecation takes indigestible substances from the body, so it …show more content…
Muscles are the only tissues in the body that are capable of moving body parts. They are able to keep the body at posture all day without getting tired. Through all of the activities of the muscles, muscles are able to contract and produce a high metabolic rate. In turn, the muscles produce waste or body heat. The muscular system has three types of muscles. Two of which, visceral and cardiac muscles, are in charge of the transportation of blood and other substances from one body part to another. The visceral muscles are made up of the stomach, intestines, and blood vessels. The cardiac muscles include the heart. The skeletal muscles are the muscles of the body that work as levers, such as the elbow, biceps, and triceps. To keep the muscular system in good working order involves eating a balanced diet, staying hydrated, and getting exercise including
Digestion is the breakdown of food into small molecules, which are then absorbed into the body. Circulatory system Respiration: the function of circulatory system delivers oxygen to the cells and removing carbon dioxide. Nutrition: carries digested food substances
[1] The muscular system is used to maintain the body, hold the body together, and to allow the body to move. Many muscles cover the body and allow it to function to the best of its abilities; however, there are three types of muscles which allow the body to function: skeletal, smooth and cardiac muscles. Skeletal muscles use connective tissue to attach to the skeletal structure, and allow for movement of the body. Smooth muscles function by forming structures such as blood vessel walls or the walls of the digestive tract. The cardiac muscle, also known as the heart, functions by pumping blood throughout the body.
The Muscular system consists of 600 muscles. The function of the system is to give strength to the body so it can perform a movement. The system consists of skeletal, smooth and cardiac muscles. The cardiovascular system and the muscular system both help each other to perform their actions. Due to the fact that muscles require a lot of oxygen the circulatory system takes in the air which is combined with the blood flow and sent to the muscles. When the body is at rest the blood flow carries nutrients to the muscles so they can be repaired. Everyday, muscles produce a lot of waste products so when the blood flow reaches the heart it is pumped into the lungs so it can be transferred out of the body. The benefits of the muscular system when working
The main function of the muscular system is to make the body move. Although it is the skeleton that enables movement, only muscles can actually move. Muscles only can pull not push, so muscles have to work in pairs to make the bones move in more than one direction and increase the possible amount of movement this way. To do that the muscles cross the joint they move, when a muscle contracts it pulls on the bones and makes them move this way. Muscles are made of many tiny muscle fibres. Those individual muscle fibres are either fully contracted or fully relaxed but they cannot all be fully relaxed at once because your muscles always have to be read to contract in case you have to defence yourself by, for example, running away or fighting. Even
There are 3 functions of the digestive system: food is broken down, nutrients are absorbed, and waste is eliminated. The food is broken down by chemical digestion (food is broken down by enzymes) and mechanical digestion (food is physically broken down). The nutrients are absorbed in the small intestine. Solid wastes are eliminated by being turned into feces (poop) and then exiting through the anus.
There around 700 muscles in your body that make up half of your body weight. Muscles are responsible for movement throughout the body, using contractions, like contracting the lungs for breathing. Besides movement, organs of the muscular system manage posture, provide strength, balance, and heat for maintaining body temperature. The main organs in the muscular system, are visceral or smooth muscles, cardiac muscles, and skeletal muscles. Each muscle is made up skeletal muscle tissue, blood tissue, tendons, and nerves. The different organs each have a specific purpose and function. Visceral muscles are found in organs like the stomach, intestines, and blood vessels. They make organs contract to move substances through the organ.. Cardiac muscles
The muscular system consists of the main organs of just the muscles. The muscular system is responsible for the movement of the human body. There are around 700 named muscles attached to the bones of the skeletal system that make up half of a person’s body weight. Each muscle is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves. Muscle tissue is also found inside of the heart, digestive organs, and blood vessels. There are three types of muscle tissue which are Visceral, cardiac, and skeletal. Visceral muscle is found inside of organs like the stomach, intestines, and blood vessels. Visceral muscle is also the weakest of all muscle tissues. Since visceral muscle is controlled by the unconscious part
The function of digestion is to break down and transport nutrients from the food to their respected destination within the body as they are added through the lymphatic system and the blood stream. Major organs involved in digestion are the mouth, esophagus, stomach, small and large intestine and the rectum. The salivary glands, liver, pancreas, and gallbladder are assisting organs in the digestion process.
The premise of the digestive system is to turn food into energy and get rid of waste. This system has two main functions, digestion and absorption. One of the system’s major parts is called the digestive tract or alimentary canal. The digestive tract is an ongoing tube that has two openings. One opening is the mouth and the other aperture is the anus. The alimentary canal consists of the mouth, pharynx, esophagus, stomach, small intestine, and large intestine. This canal also has accessory organs that include the teeth, tongue, salivary glands, liver, gallbladder, and pancreas. There is a several step process that comes with the digesting food. This process starts in the mouth. In order for digestion to become
The digestive and excretory systems help the body with the wonderful task of food. The digestive system is composed of the stomach, mouth, liver, pancreas, and the large and small intestine. It digests food and provides the
In the human body, the human digestive system is used to process food one eats by digesting it into nutrients. The body use nutrients for energy, growth, and cell repair, which are needed for humans to survive. This digestive system encompasses a long tube that runs from the mouth to the anus. It contains structures and organs through which food and liquids pass as it is being processed into forms absorbable in the bloodstream. The digestive system also contains structures through which wastes pass in the process of elimination and additionally, other organs that contribute juices necessary for the digestive process.
The muscular system consists of over 600 muscles in the body. There are three different types of muscle in the body. Skeletal, smooth and cardiac. The skeletal muscles are the muscles that are attached to the bones that help create movement in the body. The smooth muscles line the organs and veins and lymphatic system. They are involuntary muscles that are controlled by the autonomic nervous system. The cardiac muscles are the muscles found in the heart, also controlled by the autonomic nervous system.
The Muscular system is an important bodily system that we need to survive. This system is composed of it’s 3 major organs which are the skeletal, cardiac, and smooth muscles. These organs work day and night with no rest to keep us alive. The Muscular system also produces internal and external movement throughout the body, and just with this, there are still many more functions it has.
The digestive system is a series of connected organs whose purpose is to breakdown the food we consume. Food is made up of large, complex molecules, which the digestive system breaks down into smaller, simple molecules that can be absorbed into the bloodstream. The simple molecules travel through the bloodstream to all of the body's cells, which use them for growth, repair, and energy.
The digestive system is a very important but complex system. It is made up of main and accessory organs, the main organs are the mouth, pharynx, esophagus, stomach, small intestine, large intestine, rectum, and anus. The accessory organs are teeth, tongue, salivary glands, liver, gallbladder, pancreas and appendix (Thibodeau and Patton's, 2012). Both, main and accessory organs have specific roles and functions which allow digestion to happen efficiently. In order for the digestive system to make nutrients available to each cell of the body, the system uses various mechanisms. The prime mechanisms of the digestive system are ingestion, digestion, motility, secretion, absorption, elimination and regulation (Thibodeau and Patton's, 2012).
