How do the circulatory and respiratory systems work together? The main way in which the respiratory and the circulatory system work together is that the heart send blood to the lungs, which is then oxygenated, so the blood can then be sent to the rest of the body (after being pumped back through the heart).aking the world better, one answer at a time. The circulatory system transports oxygen through the body and the respiratory system supplies that oxygen. The respiratory system performs a process known as gas exchange that releases carbon dioxide from the body and brings in oxygen.

Table of Contents Circulatory System. The circulatory system includes the heart, blood, and a huge network of blood vessels that carry blood all over the body. The job of the circulatory system is to deliver oxygen to cells all over the body and then to carry out waste product like carbon dioxide. The heart is an organ made out of muscle. It’s job is to pump blood through the body. The heart has four main sections or chambers: Right atrium; Right ventricle; Left atrium; Left ventricle

- Video: Heart and circulatory system — How they work. Your heart is a pump. It's a muscular organ about the size of your fist and located slightly left of center in your chest. Your heart is divided into the right and the left side. The division protects oxygen-rich blood from mixing with oxygen-poor blood. Together, your heart and blood vessels comprise your cardiovascular system, which circulates blood and oxygen around your body. Your heart pumps about 5 quarts of blood every minute.

circulatory system and muscular system muscle fitness image by Leticia Wilson from Fotolia.com. All the systems of the body work closely together to maintain homeostasis--the dynamic balance of internal conditions which the body works constantly to preserve. The muscular system and circulatory system have an especially important relationship.he healthier and more active the muscle system, the healthier the circulatory system. When we move, the pump of our muscles prompts blood to return to the heart through the veins. Regular exercise increases both the strength and size of the heart. It also clears fatty deposits out of blood vessels.

Respiratory and circulatory systems The circulatory system contains the heart and the blood vessels and moves blood throughout the body. Our body has about five litres of blood continually travelling through the circulatory system. All our circulatory organs work together, forming a very efficient pipe network for our bodies.ulmonary circulation is the movement of blood from the heart, to the lungs, and back to the heart again. Coronary circulation refers to the movement of blood through the tissues of the heart. Systemic circulation supplies nourishment to all our body tissues. Each of our circulatory systems works independently.

How do the circulatory and respiratory systems work together? The alveoil transport oxygen from the lungs into the circulatory 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.aking the world better, one answer at a time. The circulatory system transports oxygen through the body and the respiratory system supplies that oxygen. The respiratory system performs a process known as gas exchange that releases carbon dioxide from the body and brings in oxygen.

The Heart and Blood Vessels How do the heart and blood vessels work? The heart works by following a sequence of electrical signals that cause the muscles in each chamber to contract in a certain order. If these electrical signals change, the heart may not pump as well as it should. The sequence of each heartbeat is as follows: 1  The sinoatrial node (SA node) in the right atrium is like a tiny in-built 'timer'. It fires off an electrical impulse at regular intervals. (About 60-80 per minute when you are resting and faster when you exercise.) This controls your heart rate.

Circulatory system The circulatory system includes: the pulmonary circulation, a loop through the lungs where blood is oxygenated; and the systemic circulation, a loop through the rest of the body to provide oxygenated blood.he  blood then travels to the left atrium by the pulmonary artery and  then to the left ventricle. The blood leaves the heart by the aorta  to the other parts of the body.. The circulatory system is the organ system that carries substances around our body. There is no such thing as a circulary system.

- The main function of the circulatory system is to move blood and lymph through the body. Doing this transports nutrients and oxygen to the cells of the body and removes waste products such as carbon dioxide. The circulatory system is necessary to regulate temperature and pH balance and protect the body from diseases.

Heart Anatomy The heart and circulatory system make up your cardiovascular system. Your heart works as a pump that pushes blood to the organs, tissues, and cells of your body. Blood delivers oxygen and nutrients to every cell and removes the carbon dioxide and waste products made by those cells. Blood is carried from your heart to the rest of your body through a complex network of arteries, arterioles, and capillaries. Blood is returned to your heart through venules and veins.

Circulatory system All cells in the body need to have oxygen and nutrients, and they need their wastes removed. These are the main roles of the circulatory system. The heart, blood and blood vessels work together to service the cells of the body. Using the network of arteries, veins and capillaries, blood carries carbon dioxide to the lungs (for exhalation) and picks up oxygen.

Circulatory System The circulatory system is made up of the vessels and the muscles that help and control the flow of the blood around the body. This process is called circulation. The circulatory system delivers nutrients to and from different cell. The main parts of the system are the heart, arteries, capillaries and veins. As blood begins to circulate, it leaves the heart from the left ventricle and goes into the aorta. The aorta is the largest artery in the body. The blood leaving the aorta is full of oxygen.

Effects of Vasodilation and Arterial Resistance on Cardiac Output About the Heart and Circulatory System. The circulatory system is composed of the heart and blood vessels, including arteries, veins, and capillaries. Our bodies actually have two circulatory systems: The pulmonary circulation is a short loop from the heart to the lungs and back again, and the systemic circulation (the system we usually think of as our circulatory system) sends blood from the heart to all the other parts of our bodies and back again.

- The Circulatory and Respiratory System When you breathe in, your respiratory system receives fresh oxygen. The oxygen first goes into your lungs and then into the left side of your heart. It is then pumped by the heart into your blood stream. Figure 1.2 shows the flow of oxygen and carbon dioxide pumped to the body. Blood travels throughout your body. The heart pumps blood through a system of large and small pathways that make up the circulatory system. Blood delivers vital nutrients, oxygen, and other chemicals to every cell in your body. Once in the cells, oxygen burns nutrients to make energy.
