The Cardiovascular System The heart is one the primary organs in our body. The cardiovascular (CV) system is made up of the heart‚ the blood and the vessels through which blood travels. The CV system works in sequence with the respiratory system to maintain homeostasis. The heart acts as a pump which move the blood through the blood vessels to the tissues and organs of the body. This allows the CV system to help maintain homeostasis by enabling it to carry out its four major functions

the anatomy and physiology of these three body systems; The Cardiovascular system‚ The Respiratory system and The Digestive system. The Cardiovascular System The cardiovascular system‚ also known as the circulatory system‚ consists of the heart‚ blood vessels and approximately 5 litres of blood. 55% of the blood is straw coloured yellow and 45% of the blood is made up of red and white blood cells and tiny particles called platelets. This system is powered by the heart and is responsible for

1. Why do we need a cardiovascular system? Because we need to get oxygen through our system. 2. Make sure you know which circuits the left and right heart pump into (pulmonary or systemic). Also know the status of blood (fully oxygenated or not) at -the aorta: Left‚systematic‚ and fully oxygenated. -a pulmonary vein: Left side‚ pulmonary‚ and fully oxygenated. Goes from the right side of the body(heart) into the (left) pulmonary veins then goes to the left atrium then to the left ventricle then

The human body has to be controlled from advanced systems internally of which connect in order to function effectively. There are ten main systems within the body of which all perform various activities and all interrelate with at least one other system; the nervous system. The most complex of all body systems‚ the nervous system controls all functions within the body. The main function of the respiratory system is to inhale oxygen and exhale the waste product carbon dioxide. Oxygen is breathed

The cardiovascular system is a vital part of our body and it is crucial for us to lead a healthy lifestyle to maintain the structures of our body. Structures of the cardiovascular system include the heart‚ blood vessels and blood. Structures of the Cardiovascular System Heart The heart is the most important organ in our body as it provides every part with blood. The heart pumps blood by producing electrical impulses which cause the ventricles to contract and relax and pump blood to the
