Our Complicated Body System

The human body is made up of millions of tiny cells that can only be seen under a microscope, cell also vary in shape and size. Cells are the basic structural of all living things. The human body is poised of trillions of cells. They give structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body’s hereditary material and can make copies of them. Cells all have different sizes, shapes, and jobs to do. Each cell has a different function. The actual definition of cells is the smallest structural unit of the body that is capable of

All the systems in the human body are vital to our survival and well-being. If you take away the functions of just one of these systems our whole body will cease to work properly. The main systems of the human body are the nervous, endocrine respiratory, circulatory, immune, digestive, excretory, skeletal, muscular, and the reproductive systems. They all work together in harmony and unison to keep us alive.

Frogs are called amphibians, and humans are classified as mammals. As well, our exterior appearances of frogs and humans look contrastive, but nonetheless besides the differences, our interior appearances share many similarities. Some similarities include body structure such as eyes, ears, a mouth, and nose. Other similarities include our basic organs like lungs, a stomach, and a heart. Also, just like humans frogs are composed of many different body systems, three of which are the circulatory, respiratory, and digestive systems, which work together to help them live. However, we also share many differences. Some examples of our external differences are our external appearances, such as size, skin, and colouring, and our habitats. As a

The eye is one of the most complex organs of the human body. In the human

The human body, a biological organization of physiological cascades, is surprisingly fragile but yet highly adaptable to withstand the varying challenges encountered in the lifetime of an individual. From chronic illnesses to acute and rapidly changing events, the integrated cooperation between human organ systems can dramatically influence the potential outcomes of a patient. It is multiple deployments of singular compensatory mechanisms in response to abnormal changes that provides this infinite flexibility. While this continuous flexibility is illustrated in lifestyle diseases such as hypertension and diabetes, its role in acute attention-demanding events are remarkable. An example of such an attention-demanding occurrence

I do agree that understanding body systems is the foundation for understanding other health conditions and diseases because when you understand how your body works it could help keeping the body and its systems in good condition to ensure a long and happy life. For example, when you truly understood how your heart works, you would start doing things that is best for your heart such as eating salmon because it has a good amount of omega-3s in it which is healthy for the heart. However, the environment around you also play an extremely important role because it could decide what is going to happen to your body. For example, when you know how your lung works, you will do your best to stay away from air pollution because it could suffered from

The human nervous system is composed of billions of neurons that respond to stimuli, conduct impulses, and communicate with other cells. Dendrites, a branched extension of a nerve cell, receives information from other neurons. The soma, or cell body, is responsible for whether or not the neuron sends out signals consisting of a short electrical pulse called an action potential, or spike. This spike is carried out by axons, delivering it to other neurons, and has a duration of a few milliseconds and an amplitude of 100 mV. A biological neuron model is a mathematical description of the properties of nerve cells that is designed to accurately describe and predict biological processes. One way to do so is by using the integrate-and-fire model which displays a trajectory of fluctuating potential versus time in the sub-threshold regime and outputs spikes that are triggered when the membrane potential reaches its threshold. Once this threshold is reached, the membrane potential is then reset, allowing the process to start again.

Instead, the cell goes on making new cells that the body doesn’t need. These new cells all have the same damaged DNA as the first abnormal cell does. Anyone can inherit abnormal DNA, passed on from their parents, but most often DNA damage is caused by mistakes that happen while the normal cell is reproducing. One of the most helpful websites that help us understand cancer is www.Cancer.org. It states, “In most cases, the cancer cells form a tumor. Over time, the tumors can replace normal tissue, crowd it, or push it aside. Some cancers, like leukemia, rarely form tumors. Instead, these cancer cells involve the blood and blood forming organs and circulate through other tissues where they grow” (American Cancer Society). A tumor is an abnormal lump or a collection of cells, but not all tumors are cancer. Tumors that aren’t cancer are called benign. Benign tumors can cause problems; they can grow very large and press on healthy organs and

Welcome to my body systems report.In this article I will be talking about body systems and how they work and what's their job.

The body is made up of hundreds of millions of living cells. Normal body cells grow, divide, and die in an orderly fashion. During the early years of a person’s life, normal cells divide faster to allow the person to grow. After the person becomes an adult, most cells divide only to replace worn-out or dying cells or to repair injuries. Cancer begins when cells in a part of the body start to grow out of control. There are many kinds of cancer, but they all start because of out-of-control growth of abnormal cell (American Cancer Society, 2010).

- However, when cancer develops, the cells become irregular, the old cells that should die but

According to Harris and Sherblom (2011), “A system is, by definition, a collection of interrelated parts or elements that function together to make a whole that is of a magnitude and order totally different from that of any of the individual parts. It is a set of elements bound together in interdependent relationships. The integrity of the whole depends on the mutual interaction among its parts.” If this is true, a system cannot be singular in nature. By that I must stress the term “team”. The text uses the example of the human body as a system. What better a system to reference, to display the importance of “team work” in order for a system to function, in unison, properly? If each organ system is functioning properly, the body is able to maintain its homeostasis; but if one system is failing or not functioning properly, the body moves from its state of homeostasis into a compensatory state to try and

Cancer can start almost anywhere in the human body, which is made up of trillions of cells. Normally, human cells grow and divide to form new cells as the body needs them. When cells grow old or become damaged, they die, and new cells take their place. When cancer develops, however, this orderly process breaks down. As cells become more and more abnormal, old or damaged cells survive when they should die, and new cells form when they are not needed. These extra cells can divide without stopping and may form growths called tumors.

Even though the brain is the major control center if the body, its job would not be possible without the spinal cord. The spinal cord is the major organ that helps information travel between the body and the brain. Nerves branch in the peripheral system from, either the brain stem or spinal cord, each nerve attaches to a specific area of the torso and limbs it 's responsible for communication to and from those regions. There are three very important

The way our body works is incredibly complex, but a wonderful thing that we are given. Without everything working it would be hard to do simple tasks. When certain things do shut down or stop working properly it can ruin a life. The littlest of organs can have an enormous effect on the body which it did on me. The thyroid a small organ on the front of your neck gave me some serious problems for about 2 years. From little things like sleep, appetite, and headaches it quickly scaled to many more major things like heart palpations and severe dehydration. It may seem like something very useless in the body, but I will never forget what it caused, and how hard it was to overcome it. That little organ did way more than it probably knew it could do which was giving me a completely different outlook of life itself.
