Cardiovascular system has three main functions: Transport of nutrients, oxygen and hormones to cells throughout our body and removal of metabolic wastes such as (carbon dioxide and nitrogenous wastes). Protections of the human body by while blood cells, antibodies and complement proteins that circulate in the blood and defend our body against foreign microbes and toxic. Clotting mechanisms are also present that protect the human body from blood loss after injuries. Regulation of body temperature, fluid pH and water content of
Biology Task 2 Our organs all play a role in maintaining a constant internal environment, The liver maintains a constant level of glucose and amino acids, the lungs supply oxygen to cells. The physiological reason for Mo Farah’s increased breathing is that the body is attempting to return to its normal equilibrium level of 37 degrees Celsius and maintain internal stability which is called homeostasis.This ensures that the internal body temperature remains at a set point. This is called negative feedback; the hypothalamus sends impulses through the sweat glands to secrete. This reduces the heat by evaporation of sweat. Blood is sent to the surface of the skin to dispel heat.
When you are exercising different changes occur in the body to try and deal with the change in the environment and the reaction that occurs in the body. I will also explain the homeostatic mechanisms when someone exercises. Homeostasis is for the process of the body to maintain a relatively consistent internal state. The nervous system sends and receives signals about temperature, hydration, blood pressure and much more factors. The endocrine system carries chemical messengers to adjust bodily functions.
Those that are affected include respiratory system, immune system, and nervous system. The respiratory system is a series of organs responsible for taking in oxygen and putting out carbon dioxide. The main organs in the respiratory system are the lungs. Your lungs are responsible for contracting and carrying out the exchanges of gases we breathe. It is extremely important that this systems functions properly.
My ranking of the body system and why I ranked them the way I did. Cardiovascular system: the most important of the systems it consists of the heart, the spleen and the blood vessels that are spread throughout the body services all the cells and tissues of the body, its primary objective is to continually provide nutrients to the brain. So without the whole system fails. Nervous system: this system includes the brain, spinal cord and nerves as organs. It receives information from all the other body organs and then directs each organ how to operate as a team.
Plasma carries food from the stomach to cells but carries waste from the cells to the kidneys and intestine. The body needs lots of haemoglobin because it will combine with the gases; oxygen and carbon dioxide. The red cells carry the oxygen in the arteries and capillaries to cells of the body. One function of the blood is to transport materials within plasma and hemoglobin around the body. Plasma contains hormones, nutrients and waste substances.
Water serves a number of essential functions to keep us all going: * A vital nutrient to the life of every cell, acts first as a building material. * It regulates our internal body temperature by sweating and respiration * The carbohydrates and proteins that our bodies use as food are metabolized and transported by water in the bloodstream; * It assists in flushing waste mainly through urination * acts as a shock absorber for brain, spinal cord, and fetus * forms saliva * lubricates joints According to Dr. Jeffrey Utz, Neuroscience, pediatrics, Allegheny University, different people have different percentages of their bodies made up of water. Babies have
It is very important that a person stays hydrated because water makes up more than half of your body weight, and not staying hydrated can result in your body shutting down and possible death. Your body uses water in many ways, all the cells in your body need water to function. All of your body’s tissues need water, and all of your body’s organs need water to function correctly. Some of the ways that your body uses water are ; water is used to regulate your body’s temperature, you sweet to lower your temperature when your body is overheating. Water is also used to carry vitamins and minerals to our body’s cells.
As this is a key feature of desertification it then means that the land for both these reasons is not able to be used and causing desertification to spread. These problems will continue to develop, not allowing the environment or soil to ever become sustainable. These problems are substantially higher as population increase is occurring at an extremely high rate. Currently the population is 260 million and is meant to double ever 20 years. This issue has been a larger struggle due to the harsh climate.
It’s sad to think that the state of California has already had a couple of cities run out of water. For example, cities like Fresno, Visalia, Santa Cruz, Merced, Bakersfield, and even my own hometown Porterville (10 Cities). Mainly cities that pertain to the central valley of California are running out of water and it’s becoming even harder on the farmers in the area trying to grow produce with the lack of rain and the consistent heat waves. “Governor Jerry Brown has declared this a drought emergency” (California’s Drought) A call that probably should have been made before parts of
