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

Cardiovascular System: Intrinsic Conduction System 1. The intrinsic conduction system consists of __autorhythmic____ __cardiac__ cells that initiate and distribute __impulses_____ throughout the heart. 2. The intrinsic conduction system coordinates heart activity by determining the direction and speed of ____heart depolarization____. This leads to a coordinated heart contraction. 3. List the functions for the following parts of the intrinsic conduction system: a. SA node _sets the pace for the

metabolism the first thing you might think of is the number of calories your cells burn each day. Metabolism is actually the sum of all chemical reactions that take place in the body. Metabolic reactions that produce energy are dependent on the cardiovascular system‚ which send oxygen to all the cells in your body. Although metabolism is not primarily made of reactions that burn nutrients like carbohydrates‚ fats and protein‚ these are perhaps the most widely known of the metabolic reactions. (CITE) However

The cardiovascular system‚ also known as the circulatory system‚ is composed of the heart‚ blood vessels‚ and blood. The term cardiovascular refers to the heart (cardio-) and blood vessels (vascular). The term circulatory refers to the circulation of the blood. The heart is a muscular pump and its regular contractions send blood into tough‚ elastic tubes called arteries‚ which branch into smaller vessels and convey oxygen-rich blood through the body. The arteries eventually divide into tiny capillaries

Chapter 19 The Cardiovascular System: The Heart 1. How is the heart positioned in the mediastinum? It rests on the diaphragm‚ near the midline of the thoracic cavity‚ with about two-thirds of the mass lying to the left of the body’s midline. 2. Which layer of the pericardium is both a part of the pericardium and a part of the heart wall? Serous pericardium 3. What is the function of pericardial fluid? Reduces friction between the membranes as the heart moves 4. From most superficial

The cardiovascular system is the movement of blood being permitted around the body to vital organs and muscles with the components of the heart‚ blood‚ and blood vessels combining together to make the cardiovascular system work. The cardiovascular systems is vital in the human body as it promotes the body’s delivery system for blood being pumped around the entire body for survival. The respiratory system also has importance in the body as it is the system to transport air into the lungs to aid the
