Inferior vena cava: This vessel comes from below the heart hence called the inferior vena cava and this vein carries deoxygenated blood back to the right

Our route from here will be to enter the body by injection into the right femoral vein‚ which is located in the upper thigh and pelvic region of the body and runs close to the femoral artery (Tamburlin & Severin‚ 2011). Once inside the body‚ we are to continue on a path that can lead us to the infected area. During my journey I will

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

effected for many years and continues to be useful in today’s modern practices. Intravenous (IV) therapy involves the administration of a therapeutic solution directly into a vein (“Intravenous Therapy” par. 1). The term intravenous therapy begins with the understanding of each word‚ intravenous simply means "within a vein"‚ and therapy is known as a treatment intended to relieve symptoms; therefore‚ intravenous therapy may be used to deliver medication directly into the bloodstream.

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

In the alimentary canal the processes of mastication‚ digestion and absorption take place‚ while the digestive glands secrete certain enzymes which bring about the digestion of the ingested food.

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
