The muscular system is the system in the body in charge of voluntary movements that a person performs throughout there daily lives. This ranges from walking, talking, sitting, standing, and eating to other more complex task like the pumping of blood and maintaining posture.
Organs and their functions
The muscular system contains about 650 muscles that can be categorized into 3 different types of muscles: skeletal, visceral, and cardiac muscles. Skeletal muscles associate with the daily functions and movements that a person performs. Visceral muscles are smooth muscles that can be found in organs like the stomach and intestines as well as blood vessels. Only found in the heart are the cardiac muscles that work to pump blood throughout the body.
How it works with other systems
The muscular system works with almost all the other human body systems, but works especially well with the skeletal system. The muscular and skeletal systems both work together to perform basic voluntary movements like walking and talking.

An adult human has 206 bones in their skeletal system that are connected by networks of tendons, ligaments, and cartilages. The skeletal system performs vital functions like support, protection, movement, the production of blood cells and the storage of nutrients. These functions are what enable us to live normal healthy lives.
Organs and their functions
The skeletal system is divided into 2 parts: the axial and appendicular skeletons. The axial skeleton contains 80 bones consisting of the vertebral column, the rib cage, and the skull. Its function is mostly to maintain an upright posture by transmitting weight from the upper extremities to the lower extremities. The appendicular skeleton contains the remaining 126 bones, and consists of  the pectoral girdles, the upper limbs, the pelvic girdle and the lower limbs. The function of the appendicular skeleton is movement(Ex. walking, running, etc.) and the protection of major organs responsible for digestion, excretion and reproduction.
How it works with other systems
The skeletal system is mostly known for working with the muscular system because they both interact with each other to help the human body function as well as cause movement.

The nervous system is a complex collection of nerves and special cells known as neurons. the nerves and neurons are then able to send signals to different parts of the body to perform specific functions. 
Organs and their functions
The nervous system is made of 2 different components: the central nervous system and the peripheral nervous system. The central nervous system consists of the brain, spinal cord, and the nerves. The peripheral nervous system is made up of sensory neurons, ganglia or clusters of neurons, and and nerves that connect among each other as well as to the central nervous system. The nervous system is also further divided into 2 main subdivisions: the somatic, or voluntary, component as well as the autonomic, or involuntary, component. The autonomic nervous system is in charge of regulating certain body processes without any voluntary effort like blood pressure and and rate of breathing. The somatic nervous system nervous system consists of nerves that connect the brain and spinal cord with the muscles in the human body and the sensory receptors in the skin.
How it works with other systems
The nervous system works with all the systems in the human body as it is the control center for all functions. The brain sends commands through the spinal cord as well as the nerves in the body to perform all voluntary or involuntary functions that occur within the human body.]]> 2016-04-17 16:56:32 UTC https://padlet.com/danielg242001/erj3gvz0qf8g/wish/106184053 danielg242001 https://padlet.com/danielg242001/erj3gvz0qf8g/wish/106190529 Function
The respiratory system is in charge of taking in oxygen into the lungs and releasing carbon dioxide. When we breathe in oxygen and it enters our lungs, blood cells take this oxygen and take it to parts of the body where it is needed. The blood cells also transport any carbon dioxide found in the body back to the lungs so that we can exhale it into the atmosphere.
Organs and their functions
The respiratory system has many different parts to the system and it starts at the nose when we breathe in oxygen. The oxygen then passes though a hollow part in the skull called the sinuses and then travels through the trachea or windpipe where the oxygen is filtered. The trachea branches out in the bronchi which are 2 tubes that connect to each lung and are covered in little hairs called cilia which moves mucus, a sticky fluid that collects dust and germs, up and out from the lungs. The bronchial tubes then connect to the lobes of each lung. The right lung has 3 lobes while the left one has only 2. This because the left lung needs to leave space for the heart so it isn't crushed. The oxygenated blood is then later transported to the heart and the carbon dioxide in the body is taken to lungs to be exhaled.
How it works with other systems
The respiratory system works together with the circulatory system when transporting oxygenated blood throughout the body. The oxygen is first brought into the lungs and then is taken in by the left side of the heart. once taken in by the heart it begins to pump blood cells containing the oxygen received earlier to parts of the body that need it.]]> 2016-04-17 18:53:10 UTC https://padlet.com/danielg242001/erj3gvz0qf8g/wish/106190529 danielg242001 https://padlet.com/danielg242001/erj3gvz0qf8g/wish/106193726 Function
The circulatory system is a wide network of organs and vessels that are responsible for the flow of blood, nutrients, hormones, oxygen and other gases to and from cells. The circulatory system is also responsible for fighting disease and maintaining an internal balance or homeostasis.
Organs and their functions
The circulatory system is made up of different parts that include the heart, the lungs, arteries, and veins. The lungs take in oxygen that is transported to the heart. the heart pumps the now oxygen-rich blood through the arteries connected to the heart. The veins in the human body bring in the oxygen-depleted blood back to the heart so that it can be transported back to the lungs and exhaled.
How it works with other systems
The circulatory system works in association with the respiratory system. oxygen transported into the lungs is distributed through the body when the heart takes in the oxygen and pumps it throughout the body through blood.]]> 2016-04-17 19:54:26 UTC https://padlet.com/danielg242001/erj3gvz0qf8g/wish/106193726 danielg242001 https://padlet.com/danielg242001/erj3gvz0qf8g/wish/106197559 Function
The human digestive system is a variety of organs that work together to breakdown food and turn it into nutrients that the body can use as energy. All materials that are not used are eliminated. If the digestive system were to shut down, then this would lead to the body not being able to be nourished as well as not being able to eliminate unwanted waste.
Organs and their functions
Digestion starts at the mouth where the teeth breakdown food through physical digestion. Saliva is then later used to breakdown the food even further into even smaller pieces using chemical digestion. Once the food has been reduced into smaller proportions, the food is then swallowed where it travels through the esophagus and are turned into small balls of mass. After this point, digestion then becomes involuntary and a series of muscular contractions takes the food through the rest of the system, which leads to the esophagus emptying its contents into the stomach. The stomach then breaks the mass that was once food earlier into even smaller quantities using the acids that it produces. This also kills potentially harmful bacteria that could have been on the food eaten. The now broken down mass becomes a thick paste called chyme and enters the small intestine where the nutrients are absorbed. After the nutrients are absorbed whatever material is left goes into the large intestine where the material can be made into feces and finally be eliminated from the body through the process of defecation.
How it works with other systems
The digestive system works relatively close with the circulatory system. This is because after the whole process of breaking down food is completed, nutrients from the food are then taken in by the small intestine and distributed to the rest of the body. This can only occur when blood cells take in the nutrients and deliver them to specific parts of the body
