Cell Systems And Their Function

The circulatory system would transport nutrients and oxygen to all the cells in the body. Organs include, heart, veins, and arteries. The respiratory system exchanges gases, like carbon dioxide, and oxygen so that the body will function properly. These two systems work together to get oxygen to move blood, to work out many organs in the body. Air goes in and out by the mouth or nose and comes in and out of the lungs. What comes in is oxygen, and that oxygen moves blood to the lungs. What comes out is carbon dioxide, and that moves the blood to the

The digestive, cardiovascular and respiratory system are all interrelated in order to make the human body work effectively and efficiently. The cardiovascular system and the respiratory work together by performing gas exchange which is passing of oxygen from the alveoli into the blood flow and then the carbon dioxide passes trough the blood flow and is breathed out from the body. If gas exchange didn’t take place then it will result in the cells dying. There are many other body systems that interrelate with each other e.g. the nervous system is interrelated with the muscular system.

Transport- Transportation of oxygen, nutrients and hormones to cells and removal of metabolic wastes such as carbon dioxide, heat and nitrogenous wastes.

Respiratory system, the cardiovascular system, the musculoskeletal system and the nervous system. These are the main systems within the body and are made up of individual organs that then work together. For instance, the respiratory system is made of the nose, lungs, heart and this lets us breathe.

Complete the table below for the required systems listed. You are required to list four to six of the main organs of each body system, one or two sentences explaining the function of the system itself in your own words, and a short list of five to six major diseases that afflict each system.

Plant and Animal Cells I. Introduction All organisms in life are composed of at least one or more cells. Cells are the basic units of life. There are three main features of a cell. First, all organisms consist of one or more cells. Second, cells are the smallest units of life and third, cells arise only from preexisting cells.

Consist of oral cavity, esophagus, gallbladder, liver, stomach, duodenum, pancreas, colon, cecum, appendix, jejunum, and rectum.

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

Furthermore multi-cellular organisms require specialised organ systems, whereas all the life processes within a unicellular organism take place within that one cell. multi-cellular organisms need organ systems to carry out functions such as: communication between cells including the nervous and circulatory system, to supply

The digestive system is very important in digesting food and breaking it down so it can be digested easily. The digestive system turns food into energy. Throughout the process there are nutrients which are absorbed. There are many things that contributed to the digestive system such as the mouth which produces saliva which helps to break down food and nutrients such as carbohydrates with the help of an enzyme called amylase. The major food groups which are called macro nutrients include carbohydrates, proteins and fats. All of these nutrients play an important role in the body. There are also many micro-nutrients which include vitamins and minerals which provide the body with health and well-being. The digestive system is made up of the mouth, which includes the teeth (the teeth are used to cut and grind food into smaller pieces, they contain blood vessels and nerves), tongue (the tongue is a muscle that has a rough surface including the taste buds), salvia glands (they produce salvia which moistens the food to make is easier to digest), the pharynx (this helps the food travel to the stomach, the pharynx also plays an important role in the respiratory system. It also contains 2 different flaps to separate the 2 functions), esophagus (this connects the pharynx to the stomach and transports chewed food to the stomach), stomach (this is a muscle that is

The Digestive system plays an important role in the function of the human body. The digestive system converts food to energy your body needs to complete everyday activities. The digestive system also takes the waste in your body and eliminates waste. Major organs included in the process of the digestive system include the mouth, esophagus, stomach, and small intestine. The mouth is where the process begins. Saliva is added to the food that you chew, which makes it able to travel down the esophagus.

In order for cells and organisms to “live” they need to perform certain tasks such as produce energy through respiration, send messages, maintenance and reproduction. To enable the cell to do so, it contains within small structures called organelles, each organelle is different and carries out a specific function.

THe digestive system is the system that breaks down what one eats into the nutrients the body needs to function properly. It also takes the parts the body does not need and eliminates it from the body. There are three major functions of the digestive system (Coolidge-Stolz et al 60). First, the food one eats is broken down into molecules that the body can use and turns the other parts into waste. Next, the useful molecules are absorbed into the blood and carried throughout the body. Lastly, the waste, or parts the body doesn’t need is eliminated from the body (Coolidge-Stolz et al 60). The digestive system has many parts. Some of these are the mouth, salivary gland, epiglottis, esophagus, liver, stomach, gallbladder, pancreas, large and small intestine, and the rectum. The digestive process starts in the mouth. The salivary glands release saliva that assist the teeth in breaking down food (Coolidge-Stolz et al 60). After chewing is done, one swallows and the food particles and it goes down the esophagus. Before it goes down the esophagus, the epiglottis closes so no food goes down the windpipe.The epiglottis is a tiny flap of

The digestive system is responsible for breaking down food and liquids into smaller simpler molecules. these molecules are soluble and are absorbed into the bloodstream of the cardiovascular system which then transports the nutrients and energy around the

The digestive system is when the body does to break down food. Firstly, it enters the mouth and is broken down by the teeth of the animal and saliva. Then it travels along the oesophagus to the stomach. Then in the stomach for further breaking down, it is broken down by hydrochloric acid and enzymes. The acid breaks down bacteria and the food material into smaller molecules. Once this is complete it then moves onto the small intestine. Enzymes are secreted from the pancreas into here and bile from the liver which emulsifies fats. Nutrients from the food are absorbed into the bloodstream. Then it moves onto the large intestines where water is absorbed to produce faeces waste. Then it is moved to the rectum to be released from the anus. This is the basic digestive process of a monogastric animal, other animals are more complex and different processes happen.
