This is known as the systemic circulation. The right-hand side pumps blood from the heart to the lungs and this is known as the pulmonary circulation. Blood is the fluid that constantly flows throughout our bodies. The blood carries nutrients‚ water‚ oxygen‚ and waste products to and from the body cells. There are two types of blood cells:

It was during the Renaissance period (1400s to 1700s) that many European scholars (Michael Servetus‚ Andrea Cesalpino‚ Andreas Vesalius‚ William Harvey

There are three varieties of blood vessels: arteries‚ veins‚ and capillaries. During blood circulation‚ the arteries carry blood away from the heart. The capillaries connect the arteries to veins. Finally‚ the veins carry the blood back to the heart. The digestive system consists of a series

The heart is a powerful organ responsible for the circulation of the blood and delivery of oxygen and important nutrients throughout the body. The heart is responsible for the pumping into the pulmonary artery and the aorta. The plasma of the blood is pumped around the veins in the human body.

blood passes through the heart twice in double circulatory system and is circulated in two pathways that are pulmonary circulation and systemic circulation (IvyRose Holistic‚ n.d.). In pulmonary circulation‚ the distance travel is from heart to the lungs. Deoxygenated blood is pumped to the lungs for gaseous exchange and the oxygenated blood travels back to the heart. In systemic circulation‚ the oxygenated blood is pumped out from the heart to all parts of the body via aorta. After the diffusion of

Both the cardiovascular and respiratory system help each other by working together to make sure that the tissues of the body are getting the correct amount of oxygen so that they can help the body to work efficiently as possible. They also help to make sure that carbon dioxide is forced out. The cardiovascular and respiratory system start to work together when the oxygen from the surroundings/environment enter through the nose‚ this will start the process where the body will receive the oxygen.
