The heart and lungs make up two main systems within the body, the cardiovascular system and the respiratory system.

The cardiovascular system consists of the heart, the blood vessels; arteries, veins and capillaries and the blood. While the respiratory system consists of the: Nasal cavity, diaphragm, lungs, trachea, epiglottis, pharynx, larynx, bronchioles, bronchi, alveoli and oesophagus.

Both of these systems work together forming the cardio-respiratory system which is responsible for the uptake of oxygen from the air we breathe, for the transport of oxygen around the body, and for the removal of waste products from muscles and other organs.

In the heart the SA node found in the cardiac muscle of the right atrium receives electrical impulses from the brain these are passed through the cardiac muscle of both left and right atria, only being stopped by the AV node. In the right atria deoxygenated blood from the vena cava, is put under pressure due to the contraction of muscle and is forced into right ventricle. Once the pressure builds up in the right ventricle, the AV node releases the electrical impulses, which flow through the purkinje fibres in the septum of the heart, and pass into the ventricle muscle causing both the left and right ventricles to contract and force the blood up through the semi-lunar valves. The blood in the right ventricle goes through the pulmonary artery to the lungs.

Air is brought into the lungs by diffusion when the pressure of air in the lungs is less than the atmospheric pressure; inspiration takes place as air moves from a area of high pressure outside the lungs to an area of low pressure inside the lungs. When the blood in the pulmonary arteries reaches the lungs, it is transports through the pulmonary capillaries which wrap around the alveoli in the lungs. Oxygen diffuses through the membrane separating the air and the blood, from the high pressure in the alveoli of 100 mmHg to the area of lower pressure of the blood in the pulmonary capillaries 40 mmHg. After oxygenated blood moves into the pulmonary veins, it is transported to the left side of the heart to be pumped to the systemic tissues.

The relationship between the heart and lungs are there systems, the respiratory and the cardiovascular systems. They both work in unison to supply the body’s cells and tissues with rich oxygenated blood, and at the same time removes unwanted carbon dioxide.

In the human body, the circulatory system is controlled by the heard and the lungs control the respiratory system. Both the heart and lungs work in conjunction with each other to supply oxygen to the cells and tissues and to remove carbon dioxide. The entire process basically comprises of four different processes and start with breathing after which the exchange of carbon dioxide and oxygen takes place between the lungs and the blood and both the gases are transported.

The lungs take in air, which via the principle of osmosis is passed into the blood which the heart pumps around the body. The blood carries vital oxygen from the air (the oxygen molecules are attached to the haemoglobin in the blood to form oxyhaemoglobin) to all the body's cells

The similarities of the heart and lungs is that they both improve with exercise also both the heart and lungs work in conjunction with each other to supply oxygen to the cells and tissues and to remove carbon dioxide

What happens to the oxygen level in our blood going to the small intestine after meal? It is more oxygenated or less .

They are the means for which the rest of the body relies to function and survive. Without them you would not be alive. The processing of oxygen and the rejuvenation of the blood by the oxygen enrichment from the lungs are the means of powering the body.

The interrelation between these two systems is Respiratory system is joint with cardiovascular system. They work together to supply oxygen to all the cells and tissues of the body and remove unwanted carbon dioxide.
