The digestive system is one of the most overlooked systems in the human body. Although most people cannot sense the system at work like they do when they breathe in air or feel their heart beat, it still continues to deliver nutrients throughout the systems. The digestion system is responsible for nourishing the human body with the energy necessary to stay healthy and getting rid of the unnecessary materials (Marieb 1989). The digestive system is composed of the mouth, pharynx, esophagus, stomach

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

After much consideration and time to process all of the organ systems in the human body, I feel as if the circulatory system is a significant key element in maintaining homeostasis in the human body. The circulatory system is a vast network of organs and vessels that is responsible for the flow of blood, nutrients, hormones, oxygen and other gases to and from cells. The circulatory system is an organ system that permits blood to circulate and transport nutrients (such as amino acids and electrolytes)

The heart is one of the most important vital organs to sustain life in the human body. The heart is a muscle pumping organ that generates two different types of circulatory loops within the human body. These include the Pulmonary Circulation and the Systemic Circulation. The Pulmonary arteries brings blood from the right side of the heart to the lungs where then the blood picks up oxygen and returns to the left side of the heart. The pumping chambers that support the pulmonary circulation are the

“not human”. However, today the word represents “without compassion for misery and suffering”. Animals suffer from pain the same way humans do, so why should they undergo this kind of treatment? Animal testing is cruel and should be eliminated as a means of research due to the fact that it often ends in killing helpless animals. Animal experimentations vary from simple to severe. However, why should there be a severe category when the results and solutions are not guaranteed? The human body and its

homeostasis of the human body. The way that the body reacts and adapts to physical stress depends on various components. Specifically, exercising in the heat can overload the body and decrease its capability to adapt to the stress that it is being put through (Nielsen, Hales, Strange, Christensen, Warberg, & Saltin, 1993). Compared to a more neutral environment, exercising in the heat results in alterations of the circulatory system, thermoregulatory system, and endocrine system (Nielsen, Hales, Strange

The Three Human Body Systems Describe the overall function of each system Systems Function Respiratory system The function of the respiratory system is to carry oxygen to the lungs. Oxygen in the air diffuses out of the lungs and into the blood, while carbon dioxide diffuses in the opposite direction, out of the blood and into the lungs. When we breathe, we inhale oxygen and exhale carbon dioxide. Digestive system The function of the digestive system is digestion and absorption. Digestion is

The human body is a complex network that has many organ systems designed for proper functioning. As the body ages over time, it also affects the effectiveness of these organ systems. One of the organ systems that demonstrated the most significant age-related changes have to be the musculoskeletal system. The musculoskeletal system provides the most obvious external signs of aging because its main function is to provide protection, support and movement of the muscles and bones (Aldwin). These functions

thought about how humans would be without bones? They would not be able to function the way that they do now if it did not have bones. The skeletal system is a highly important system in the human body, it functions as support, protection, and creation of red blood cells. This system is composed of bones and joints, an average adult contains 206 bone and an average child contains 270 bones because as a person grows the bones fuse together to create a single bone. The skeletal system is divided in to
