The difference is internal respiration happens at the cellular level while external respiration is the actual breaths. 2. What are the key functions overall of the respiratory system? The key functions of the respiratory system is to bring air and blood into the alveolar air sacs so that the air can enter into the bloodstream while the carbon dioxide exits. It also maintains the body’s pH levels and body temperature.
It has many different components within the cardiovascular system too, the main components include the heart, arteries, veins, capillaries and the blood. The heart is the key organ to the circulatory system. Its main function is to circulate oxygenated blood around the body and to deposit carbon dioxide into the lungs so it can be exhaled. The cardiovascular system works with a persons metabolism and are designed to do that in order to make sure the nutrient molecules are transported around the body to parts where they are needed. The Respiratory System The respiratory systems main function is to inhale oxygen and exhale carbon dioxide.
Nasal cavity – Preferred entrance for outside air into the respiratory system. The hairs that line the inside wall are part of the air-cleansing system. Larynx – Voice box. Contains the vocal chords. Moving air breathed in and out creates sound.
This system includes your airways, your lungs and the blood vessels and muscles attached to them that work together so you can breathe. The respiratory system's function is to supply oxygen to all the parts of your body. It achieves this through breathing: inhaling oxygen-rich air and exhaling air filled with carbon dioxide, which is a waste gas. The respiratory system is made up of airways these are your nose, mouth, voice box, windpipe and bronchial tubes, and the lungs and the muscles and blood vessels connected to them. Your respiratory system works by you breathing air in through your nose and mouth, which wet and warm the air so it wont irritate your lungs.
Oxygen is delivered to the body. vii. Carbon dioxide is passed from the blood into the lungs. The air enters through the nose and mouth and there are tiny hairs inside your nose and in the throat called cilia that traps the dust particles before it travels down the trachea into the bronchus then into the bronchioles and into the alveoli which you will find in the lungs. The alveoli passes the oxygen to the blood capillary by diffusion (high – low) and this is also how the waste (carbon dioxide) is passed back to the lungs to be breathed out this is why there is only a thin membrane so it can be passed through easily.
The respiratory and circulatory systems work together to deliver oxygen to cells of the body (the lungs through air exchange, and the circulatory system by delivery of hemoglobin containing red cells to the capillaries where oxygen is released into the tissues) and removal of carbon dioxide. The circulatory system delivers nutrients absorbed through the walls of the small intestine to other organs (such as the liver, muscles, brain, heart), and delivers oxygenated blood to the digestive system. You breathe in oxygen into your lungs. The oxygen diffuses across the thin walls of the alveoli in the lungs and the thin walls of the blood vessels in the lungs into the blood stream. Here it attaches to the hemoglobin molecules inside red blood cells.
1. Cardiovascular System is a complex network of the heart, blood vessels and blood. Its job is to deliver nutrients to the human body and remove excretory products from the body parts, it’s also protects the human body against infections, distribution of heat. At the centre of the cardiovascular system is the heart, a four chambered pump that dispenses blood to the arteries. The arteries carry nutrients and oxygenated blood to the body’s tissues.
D1 The cardiovascular and respiratory system interlink with each other, this is because they both have a link when it comes to gases exchange. This is because inside the lungs there are air sacs they are called the alveoli there are millions of alveoli, around each alveoli are capillaries which are small blood vessels, as the walls of this is thin carbon dioxide goes into the alveoli from the capillaries and the oxygen goes back into the capillaries which then goes into heart, and the heart pumps blood all around the body. These systems work very closely together, this is to make sure that organ tissues get enough oxygen. Oxygen is needed for cellular function. The air which we breathe in which is kept in the lungs, is the transferred into blood.
Right now I am located in the right femoral vein, which is located in the upper thigh and pelvic region of the body. It is also one of the largest veins in the venous system. The femoral vein’s purpose is to take all the blood in the lower region of the body and deliver it to the heart via the iliac vein. Today’s
This path will divide into even smaller branches that are known as bronchioles. At the end of the bronchioles are very small air sacs called alveoli. They deflate during exhalation and inflate when you inhale. The gas exchange of oxygen cycles through the lungs and then the blood stream as the walls of the alveoli shares the same walls with capillaries making the exchange of oxygen for carbon dioxide between the two very easy. The oxygen molecules attach to the red blood cells as the red blood cells move towards the heart, as the carbon dioxide is evacuated from the body by the exhale.
