System connection
1. Human body is made of several different systems that must work together to carry out the various processes necessary to promote good health. When something goes wrong in one system, it most likely will affect another system. Here, I have three system to explained how the inter connect and function together to achieve the above goal; there are, Cardiovascular system, respiratory system and digestive system.
Circulatory system is made up of fluid, vessels, and muscular pump which is collectively called cardiovascular system. Cardiovascular system has three main functions: Transport of nutrients, oxygen, and hormones to cells through out the body and removal of metabolic wastes (carbon dioxide, and nitrogenous waste). Protection of the body by white blood cells, and antibodies. And finally, regulation of body temperature.Digestive system consists of series of connected organs that together, allow the body to break down and absorb food, and remove waste.Respiratory system allows us to take in vital oxygen and expel carbon dioxide. It consists mainly of the trachea, the diaphragm and the lungs.
Most of the task in our body require the support of two or more organs system working together. For example, cellular respiration is a task that requires oxygen and food. The respiratory system brings oxygen into lungs when we breath. The digestive system breaks food down into nutrients such as glucose. The circulatory system then takes over, by transporting glucose and other nutrients from the digestive system to the cells. The circulatory system also transports oxygen from the lungs to the cells. Finally, the cells have what they need for cellular respiration: oxygen and glucose. The teamwork however does not end here; the circulatory system also transports carbon dioxide waste from the cells to the lungs of the respiratory system. Through gas exchange in the lungs, carbon dioxide waste is removed from our body when we breath out.
Homeostasis
2. Homeostasis is a condition of equilibrium in the body’s internal environment due to the ceaseless interplay of the body regulatory processes. It can also be referred to the ability of the body to maintain a constant internal environment in response to environmental changes. Communication within the body is essential for homeostasis. This communication is accomplished mainly by the nervous and endocrine system, which uses neural electrical impulse or blood-borne hormones respectively, as information carrier. Homoeostatic control mechanism is either negative feedback mechanisms or positive feedback mechanisms. In negative feedback mechanism, the output shuts off the original effect of the stimulus or reduces its intensity. While the positive feedback response enhances the original stimulus so that the response is accelerated.
Insulin which is produced by the pancreas, is one of the numerous hormones which can be used to maintain homeostasis. The main factor that influences the released of insulin is elevated blood glucose level which stimulates pancreatic beta cells to secretes insulin. After ingesting a meal, which is predominantly carbohydrates, the blood glucose level increases dramatically due to the breakdown of the complex carbohydrates into sugar such as glucose. As blood sugar rises, receptors in the body sense this change and the pancreas (control center) secrete insulin in to the blood. This change in turn prompts body cells to absorb more glucose, removing it from the blood stream. As the blood sugar falls, the stimulus for insulin release ends. This goes to show that, the body’s ability to regulate its internal environment is fundamental.

System connection
1. Within the Human body there are various systems that work hand in hand carry out
various processes that are of the essence in guaranteeing good health. This is so since faults in a
single system, end up affecting other body systems. In this paper, how the cardiovascular, the
respiratory as well as the digestive systems are interconnected as well as how they function will
be explained
The cardiovascular system which is also known as the Circulatory system comprises of
fluid, vessels, as well as a muscular pump. The functions of this system include transporting
nutrients hormones & oxygen to cells in the body as well as removal of m...
