Circulatory system is the system which circulates everything throughout the body. Blood is the fluid that circulates food and water to the different body parts. Blood flows through blood vessels. Heart is the organ that pumps blood to the different parts.
Circulatory system is the system which circulates everything throughout the body. Blood is the fluid that circulates food and water to the different body parts. Blood flows through blood vessels. Heart is the organ that pumps blood to the different parts.
Blood is made up of plasma, blood cells, proteins and salts. Plasma is the fluid part of blood which contains 90% of water. Blood cells are the solid part of the blood which are of three types-
?Red Blood Cells or RBCs are used for transporting food, oxygen and other substances to other part of body along with removing waste.
?White Blood Cells or WBCs are used for fighting against the foreign particles that enter the body since they are specialized in defense.
?Platelets are used for clotting in blood at the time of wound or cut to stop excess flow of blood.
Blood vessels are the carrier of blood through which the blood travels to different parts of the body. There are two types of blood vessels-
?Arteries- These carry oxygenated (oxygen-rich) blood. These are thick, elastic and carry the blood away from the heart. These are divided into small network of blood vessels known as capillaries.
?Veins- These carry deoxygenated (carbon dioxide-rich) blood. These are thin, elastic and bring the blood towards the heart.
It?s a fist-size organ that is located near a chest but slightly towards left. This works non-stop and pumps blood. If this stops beating, a person dies. There are four chambers of heart where the mixing of oxygenated and deoxygenated blood takes place. The four chambers are composed of two atria and two ventricles. Atria are upper chambers while the ventricles are lower chambers.
In humans, the circulation is called double circulation owing to the fact that blood circulates through the heart twice.
Veins collect the deoxygenated blood from various parts of the body > Right Atrium > Right Ventricle > Pulmonary Arteries > Lungs > Pulmonary Veins > Left Atrium > Left Ventricle > Arteries carry the oxygenated blood to the different parts of the body.
Lymph is another body fluid that is present in the human circulatory body. It is also referred to as the tissue fluid. It is colorless fluid which contains salts, water, proteins etc which circulates and transports the digested food and absorbed fat to the intercellular spaces in tissues.
