The lungs main function is to help oxygen from the air we breathe enter the red cells in the blood. Red blood cells then carry oxygen around the body to be used in the cells found in our body. The lungs also help the body to get rid of carbon dioxide when we breathe out. The most important muscle of inhalation is the diaphragm. Found beneath the lungs, the diaphragm is a dome-shaped muscle.
1. List the structures and functions of the cardiovascular system. Do not forget blood and vessels are part of this system. The cardiovascular consists of the heart, blood vessels and blood. It has three functions one of them is that it transports nutrients, oxygen and hormones to cells throughout the body and removes wastes such as carbon dioxide and nitrogenous waste.
The heart, blood, and blood vessels all form the circulatory system, also known as the cardiovascular system. As one of the most important systems in the human body, the circulatory system transports oxygen and nutrients to tissues and removes any waste products. Without the circulatory system, your organs wouldn 't be able to function, causing death. With the blood vessels taking blood around the body, the heart pumps all this blood. According to Ballard, "Inside the heart there are four spaces called chambers.
Introduction The human respiratory system is a series of organs responsible for taking in oxygen and removing carbon dioxide, a waste product that if allowed to accumulate, can be lethal. The respiratory system works with the circulatory system in that the red blood cells collect the oxygen from the lungs and carry it to the parts of the body where it is needed. This project will take you through the functions and anatomy of the of the respiratory system, the mechanics of breathing, the disorders of the system and how massage or holistic approaches can be used to treat these diseases instead of traditional medical routes. Functions of the Respiratory System Through breathing, inhalation, and exhalation, the respiratory system facilitates the exchange of gases between the air and the blood and between the blood and the body’s cells. The respiratory system also helps us to smell and make a sound.
The functions are allows movements of body parts, works with skeletal system to help us move, maintains posture and generates warmth. The respiratory system’s functions are to breathe, exchanges gases between lungs, and get rid of carbon dioxide from the body. The circulatory systems The functions are to carry digested food, dispose waste that could harm the body, delivers oxygen to the cells and removes carbon dioxide, helps protect the body from diseases, and it provides transport for hormones. The digestive system function is
To permit the pumping of blood, ventricles and atria contract and relax at different time; at the same time, systemic circulation and pulmonary circulations bring blood into atria via vena cava and pulmonary vein respectively. At this moment, the volume of atria increases to receive blood from vena cava and pulmonary vein, and this builds up the pressure which opens atrioventricular valves; opening of atrioventricular valves allow blood to flow from atria to ventricle as well as preventing flow back of blood into atria from ventricles. The flowing of blood into ventricles increases the volume of ventricles; the blood from left ventricle is pumped by the heart via the main artery called aorta to the rest of the body, whereas blood from right ventricle is pumped by the heart via pulmonary artery to the
Prepare yourself for witnessing the shocking reality that your lungs deserve more oxygen. Consequently, imagine the state of your brain when it is fueled with ample amount of oxygen. The brain is unarguably the focal point for thought’s and thereby the energy. Once the conscious part of the brain is charged with oxygen, it opens the doorway to energizing the sub-conscious mind. Once you begin the journey into the sub-conscious, flood gates open towards activating the energy centers of the body, the chakras and the kundalini.
Blood contains plasma, red and white blood cells, and platelets, and runs through vessels that are categorised in to arteries, veins, and capillaries. Each of these has specific function, such as the veins being carriers of carbon dioxide rich blood from all parts of the body back to the heart, and the arteries carry oxygenated blood away from the heart to the cells tissue and the organs. Lastly the capillaries join up to form veins which empty into the heart.The heart is a hollow fibrous muscle that pumps blood by its rhythmic contraction, relaxation an expansion of the arteries. This is what is known as heart beats, and it does
Gas exchange is the exchange of oxygen and carbon dioxide across a membranous surface through diffusion, allowing oxygen to be extracted from the environment and transferred into the organism’s cells while carbon dioxide is simultaneously released from the cells. Efficient gas exchange is essential for the survival of animals (fish, insects, mammals) because it provides oxygen (required for cellular respiration) to the cells of the animal which is essential as respiration provides energy for the cells to live allowing the animal to survive, and because it releases carbon dioxide (waste product of respiration) from the body. Respiration is a chemical process that occurs in the mitochondria of living cells to release energy from food. Animals (fish, mammals, insects) mainly rely on aerobic respiration to release energy required for cellular processes. Aerobic respiration requires oxygen and produces carbon dioxide as a waste product so in animals (fish, mammals, insects) these two gases are exchanged across gas exchange surfaces.
For their respiration, considering rats are mammals, they have a gas exchange system which assist and allows them to breathe oxygen and for it to function. It's mainly about exchanging gases with the environment. Its job is to bring oxygen into the body and get rid of the carbon dioxide, which is a waste gas from its body. They have lungs (which is the main organ for respiratory system) where gas exchange occurs. Since the lungs are deep inside the body, it is moist making it harder for moisture to evaporate.
