The right atrium pumps blood into the right ventricle. Then the right ventricle pumps blood to the pulmonary trunk, through the pulmonary arteries and into the lungs. In the lungs the blood picks up oxygen that we breathe in and gets rid of carbon dioxide, which we breathe out. The blood is becomes rich in oxygen which the body can use. From the lungs, blood drains into the left atrium and is then pumped into the left ventricle.
Cardiovascular system The function of the cardiovascular system is to deliver, oxygen and nutrients to different cells in the body and also to remove metabolic waste. The cardiovascular system supply oxygen from the lungs to all the tissues in the body. This system also delivers carbon dioxide to lungs from different parts of the body; the carbon dioxide will be removed from the body through breathing. Respiratory system The respiratory systems function is to supply blood with oxygen; the reason for this is so that the blood is able to transport oxygen to all the different parts of the body. The respiratory system does this through breathing, when an individual breath in they inhales oxygen whereas when they breathe out they exhale carbon dioxide.
The lungs add oxygen to the blood and remove carbon dioxide. Then the left side is responsible for accepting blood from the lungs and pumping it back out into the body. Think of it like a cycle where blood flows like this: From the body into the top right chamber (right atrium) -- down into the bottom right chamber (right ventricle) -- out to the lungs -- back to the top left chamber (left atrium) -- down to the bottom left chamber (left ventricle) -- then out to the body. The heart is innervated by the autonomic nervous system, but it also has its own system to generate electrical impulses that stimulate cardiac muscle to contract. These electrical impulses can be recorded in an ECG (electrocardiogram) and used to detect problems with the heart.
The capillaries are part of the cardiovascular system. The oxygen binds with the haemoglobin, which is a red pigment located in the red blood cells. The oxygen is transported to the pulmonary veins and oxygenated blood is pumped to the left side of the heart. From the left ventricle, the oxygenated blood is pumped through the aorta, travels to smaller arteries until it reaches the capillaries. The oxygen from the oxygenated blood moves out from the capillaries and travels to the cells of the body.
Bronchiole’s have small air sac called alveoli attached to them, which inflate during inhalation and deflate during exhalation. Gas exchange delivers the oxygen from the lungs to the bloodstream, and the elimination of carbon dioxide from the bloodstream to the lungs. Capillaries lie within the walls of the alveoli which make it possible to diffuse the oxygen and carbon dioxide between the alveolus and capillary. The oxygen attaches in blood vessels and carbon dioxide is eliminated during exhalation. 3.
External respiration which is also known as breathing refers to the inhalation of oxygen from the air into the lungs and expelling carbon dioxide from the lungs to the air. External respiration is a physical process during which oxygen is taken up by capillaries of lung alveoli and carbon dioxide is released from blood. Respiration occurs through our mouth, nose, trachea, lungs and diaphragm. Oxygen enters the respiratory system through the mouth and the nose. The oxygen then passes through the larynx, and the trachea.
Cells can also store the molecules for other use. The purpose of the respiratory system takes in oxygen and moves that oxygen into the blood by allowing it to move across the lungs into the blood vessels. The circulatory system then carries oxygen to all the cells in the body and picks up carbon dioxide waste, which it returns to the lungs. Carbon dioxide diffuses from the blood into the lungs, and you exhale it into the atmosphere. The respiratory system and the Digestive System are interrelated because the body cells depend upon products of both the respiratory and digestive systems functions in order to maintain themselves.
The blood vessels are a intricate network of tubes that transport blood throughout the body. These vessels carry blood from the heart via the arteries ,then arterioles, then to capillaries or sinusoids, to venules, to veins and back to the heart. The final component to this structure is blood that delivers nutrients and removes wastes that are a by product of cellular processes that happen within the body. What is its
On the right atrium receives deoxygenates red blood cell travel back in heart through the superior and inferior vena cavaes. 2. It enters the right atrium is full and when the right atrium is full it force to open the tricuspid valve and blood goes
Carbon dioxide is released by the red cell, easily passes through the capillary wall into the space in the air sac of the adjacent alveoli, and is then eliminated with each breath out of the mouth (exhalation). Oxygen present in the air sac easily passes into the capillaries and into the red blood cells. The capillary network carrying this oxygen-rich, bright red blood empties into the left side of the heart where it is pumped to all the tissues of the body. Thus, the cycle or circle of blood is complete; hence, the name
