the pressure of your arterial heart beat in your wrist when you take your pulse. 3. Veins Carry Blood Back to the Heart Veins carry deoxygenated blood back to the heart‚ so it can be pumped into the lungs where it will gather more oxygen. Veins have thinner walls than arteries‚ because‚ by the time your blood reaches your veins‚ it has lost much of the pressure it had when it was pumped out of the heart. Veins are usually located further beneath the skin than arteries. 4. Arterioles and Capillaries

Chapter 12: Cardiovascular System 12.1 3 types of blood vessels * Arteries: carry blood away from the heart to the capillaries * Capillaries: permit exchange of material with the tissues * Veins: return blood from the capillaries to the heart. Arteries Wall has 3 layers * Endothelium: inner layer‚ made up of simple squamous epithelium‚ with a connective tissue basement membrane that has elastic fibers. * Middle layer: thickest later and consists of smooth muscle that can

and vessels (혈관)‚ arteries (동맥)‚ capillaries (모세혈관) and veins (정맥). A functional cardiovascular system is vital (필수적인) for supplying oxygen and nutrients to tissues and removing wastes from them. Paths of Circulation: Pulmonary(폐의) Circuit : carrying blood to the lungs and back 1. The pulmonary circuit is made up of vessels that convey blood from the right ventricle to the pulmonary arteries to the lungs‚ alveolar capillaries‚ and pulmonary veins leading from the lungs to the left atrium. 2.

Describe the physiology of the cardiovascular system in relation to energy. A.T.P is stored‚ chemical energy in the cell‚ without A.T.P we would die. To make A.T.P we need glucose oxygen. Carbon dioxide and heat are the waste products. The main function of the cardiovascular system in relation to energy is to transport the oxygen and glucose to the cells‚ and to transport the waste products such as carbon dioxide and urea (waste product from protein digestion) away from the cells and to the lungs

The Circulatory System The circulatory system in anatomy and physiology is the course taken by the blood through the arteries‚ capillaries‚ and veins and back to the heart. In humans and the higher vertebrates‚ the heart is made up of four chambers the right and left auricles‚ or atria‚ and the right and left ventricles. The right side of the heart pumps oxygen-poor blood from the cells of the body back to the lungs for new oxygen; the left side of the heart receives blood rich in oxygen from

The heart pumps blood to 9 liters per day‚ making from 60 to 160 beats per minute. The heart is covered with a dense fibrous membrane - the pericardium‚ forming serous cavity filled with liquid
