Physiology This essay will aim to give a general insight into the anatomical and physiological structures within the human body. The essay will also explain the structure and functional systems in the body with a full understanding of how they connect and work together simultaneously in order to create a homeostatic balance within the body. Every organ in the body plays a vital role to maintain equilibrium within the body. Physiology is the natural study that relates to the parts and functions of the body and how they interact with each other to promote the body’s health and wellbeing.This includes the cells, molecules, muscles, organs, and all of their functions and chemical processes …show more content…

breathing, eating, elimination (urination and defecation), movement and coordination or other. Choose any One activity. The human body’s reaction to everyday activities differs with each individual. Breathing is the natural process of inhaling oxygen and exhaling carbon dioxide. The two main functions of the respiratory system is to distribute oxygen (O2) through the lungs to the tissues within the body. It’s also responsible for removing carbon dioxide (CO2) from the tissues back through the lungs. (ptdirect.com) Take for instance the 25 year old young man and his body’s response to breathing. When the young man inhales, oxygen is carried to the lungs by the upper respiratory system. Oxygen enters the bloodstream through the alveoli which are the tiny air sacs in the lungs where gas exchange takes place and then into the blood vessels to each cell in the body where through the respiration process energy is created which the young man needs to perform his everyday activities. Energy is also vital for growth, muscle contraction, active transport, cell division and nerve impulses. Respiration is the chemical reaction involved in breaking down of nutrient molecules in living cells to release energy. There are two types of respiration, aerobic and anaerobic respiration which is involved in the process of creating energy. Aerobic respiration is the release of a fairly large portion of energy cells produced by the breaking down of food in the presence of oxygen. Anaerobic respiration is the reverse of aerobic respiration, where no oxygen is required and a very small amount of energy is released. Anaerobic respiration occurs in muscles during vigorous exercise(Bitesize

    In this paper I will clarify the relation between the integumentary system and the skeletal system. During this paper I will address how the two systems work together to maintain homeostasis and what occurs when balance is not maintained between the integumentary and skeletal system. During this paper I will explain how osteoporosis is directly linked between both the integumentary and skeletal system and ways to prevent or yield this disease.

  • The Lungs And Respiratory System

    1005 Words  | 3 Pages

    The lungs are a vital part of the respiratory system, a group of organs and tissues that work together to help humans breathe. The system’s main job is to move fresh air into the body while removing waste gases. Lungs are important because every cell in the body needs oxygen to live. The air we breathe contains oxygen and other gases. Once in the lungs, oxygen is moved into the bloodstream and carried throughout the human body. The bloodstream then carries the waste gas back to the lungs where it is removed from the blood stream and then exhaled. The lungs and respiratory system automatically perform this vital process, called gas exchange (American Lung Association). Lungs contain millions of air sacs called alveoli. With each breath,

  • Skeletal System Of The Human Body

    1354 Words  | 3 Pages

    The human body is made up of 12 different systems. Each system has a separate function while some do work together. One system is called skeletal system which is to serve as a support the body, mineral storage, energy storage (fat), blood cell production, movement (leverage), and protect the internal organs. (Martini, 112). With the help of the muscular system, it keeps us moving and makes us to do tasks that we don’t think about like swinging the arms while running. The average adult skeleton has 206 bones that are joined together by ligaments (bone to bone) and tendons (muscles to bone) to make a protective framework for the tissues and muscles. The vital organs are also protected by the skeleton, brain is covered with skull just like heart

  • Important Body System: The Circulatory System

    738 Words  | 2 Pages

    One important body system is the circulatory system. The systems job is to pump blood to all parts of the body. The blood circulates inside of many tubes and blood vessels which are found in your body. Blood vessels carry the blood to all parts of the body. Oxygen goes into the blood every time we take a breath. Carbon dioxide is a kind of gas. The blood carries carbon dioxide from the cells to the lungs. When a person breathes out, the body is getting rid of carbon dioxide. Your circulatory system works twenty-four hours a day, seven days a week. It even works when you are sleeping. The circulatory system delivers food, fluids and chemicals to cells throughout your body. It helps to clear your body of waste and carries cells that fight diseases. If your circulatory system would stop working, your cells would starve. Sometimes a doctor would give a patient a vaccine directly into the circulatory system so the medicine should travel to the parts of the body that need it. The circulatory system is made up of three main parts: the heart, the blood vessels, and the blood. The two main kinds of blood vessels are arteries and veins. There are also smaller vessels called capillaries. Arteries and veins are connected by capillaries. A heart of a human is a muscle. The heart has a left side and right side. On the right side, blood enters the heart from the body and then goes from the right side of the heart and to the lungs. In the lungs, it picks up oxygen and returns to the left side of the heart. The oxygen and the blood are then pumped to the body. The heart contains valves. The valves function is to keep the blood flowing in one direction. Each side of the heart is divided into two parts. The upper chamber is called an...

  • The Respiratory System: A Review of the System, Its Components, and Diseases That Can Affect It

    761 Words  | 2 Pages

    The respiratory system is made up of the organs and tissues in your body that help you breathe. The goal of breathing is to deliver oxygen to the body and take away carbon dioxide, a waste product that can be deadly if allowed to accumulate. The cells of the human body require a constant stream of oxygen to stay alive. The body needs oxygen to provide energy and growth to body cells. The respiratory system resides in the upper abdomen and chest area where the oxygen comes in through the nose, through inhalation, and is processed by the lungs. After air leaves the head it travels down through the trachea. It divides into two branches, the left and right bronchus, that enters into the lungs. There it goes into a thin membrane lining the walls of the lungs called the alveoli. “As a result, oxygen diffuses across microthin membranes into the blood from the alveoli and carbon dioxide diffuses into the alveoli from the blood” (Petechuk, 2004, pg. 20). So when you inhale, oxygen goes into the blood, and when you exhale carbon dioxide comes out of the blood.

    One of the human anatomy system supplies humans’ structure and development. This system is the skeletal system. The skeletal system in the body provides with the shape, support, and movement of the body, and protects its organs. The bones in the humans body protect it with and supports its organs from any external force acted upon it. The major organs such as the heart and the brain are supported and protected by bones. The ribs in the body form a cage to support and protect the heart. While similarly, the skull supports and protects the brain from any external force. The skeletal system provides movement because of the way the bones are attached to the joints, muscles, tendons, or ligaments allowing the body to move...

The organ systems that are going to be wrote about is the digestive system, the circulatory system, the respiratory system, the nervous system, and the skeletal and muscular system; all these systems are what make the human body function the way it does. The cells have to communicate to get some of these jobs done, and I will write about how cells do communicate to get the jobs done.
