The cardiovascular system plays a vital role in circulating blood throughout the body to maintain human life. The system consists of a heart and blood vessels that help delivers blood containing oxygen and nutrients to the body organs and tissues for function. The heart is a muscular body organ located on the left side of a human chest. The heart has four chambers are known as the right atrium‚ right ventricle‚ left atrium and the left ventricle. Blood travels through the four chambers by the heart

Cardiovascular The cardiovascular system is consists of the heart and network of arteries‚ veins‚ and capillaries that transport blood throughout the body. There are two primary circulatory loops in the human body: the pulmonary circulation loop and the systemic circulation loop. The heart is a muscular organ about the size of a closed fist that functions as the body’s circulatory pump. It takes in deoxygenated blood through the veins and delivers it to the lungs for oxygenation before pumping it

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

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

Trace the path of a drop of blood from the time it enters the vena cava until it reaches your little finger. Be sure to include the types of blood vessels involved. Deoxygenated blood enters the right atrium from superior and inferior vena cava after having been circulated through the body. ----------------------- From the right atrium‚ blood moves to the right ventricle and is pumped through

Performing cardiovascular and respiratory assessments is important in patients of all ages. Respiratory assessments determine the sufficiency of the oxygen in the body. This type of assessment can determine of there is enough oxygen in the body and if it is traveling adequately to maintain the health of the patient. Cardiovascular assessments are important for comparable reasons. They ensure that the heart is performing sufficiently enough to properly deliver blood throughout the body. There are

Unit 5 – Anatomy and Physiology – Assignment 3 In this assignment I will outline 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
