Blood also carries waste such as carbon dioxide to the lungs for gas exchange and metabolic waste to the kidneys for filtration and excretion. The cardiovascular system comprises of three different parts these being the heart‚ blood and

Case Study 20: The Digestive and Urinary Systems 1) Marissa‚ a newborn with a cleft lip and palate‚ is the third child of Juan and Maria. Both Juan and Maria are “visually alarmed” at Marissa’s appearance; however‚ Juan is more distant and reserved. Maria is very concerned with Marissa’s wellbeing and future and seems to take blame for Marissa’s physical condition. 2) The incidence of cleft lip (CL) with or without cleft palate (CP) is approximately 1 in 800 live births. The incidence of CP alone

RESPIRATORY SYSTEM Respiratory System Organs and Its Functions Introduction to the respiratory system organs: The respiratory system is the system of the human body by which it produces energy needed for life processes. This energy is produced by the breaking down of glucose molecules in all living cells of the human body. Introduction to the respiratory system organs: In simple terms‚ Oxygen taken in to the body through air breathed in is transported to all parts of the body‚ and it

Case Study # 2: Age-Related Changes that Occur in the Cardiovascular System Sarah Miller ITT Technical Institute As the heart ages it goes through changes such as thickening of the walls‚ slowing heart rate‚ decrease in maximum heart rate‚ loss of efficiency in pumping. The layers of the heart include the pericardium‚ epicardium‚ myocardium‚ and endocardium. The pericardium is the membrane that protects; it is a sac that the heart sits in and has a layer of fluid between for shock and absorption
