- Central Nervous System (CNS) Definition
| B2- Cartilage : Cartilage is an important structural component of the body. It is a firm tissue but is softer and much more flexible than bone. Cartilage is a connective tissue found in many areas of the body including Joints between bones e.g. the elbows, knees and ankles. Ends of the ribs. C- Central Nervous System (CNS) Definition Damage to the brain can be caused by many things, for example, trauma and ALS. The central nervous system consists of the brain and spinal cord D- Circulatory system : System that transports nutrients, respiratory gases, and metabolic products throughout a living organism, permitting integration among the various tissues. The process of circulation includes the intake of metabolic materials, the conveyance of these materials throughout the organism, and the return of harmful byproducts to the environment Blood: fluid that transports oxygen and nutrients to the cells and carries away carbon dioxide and other waste products. Technically, blood is a transport liquid pumped by the heart (or an equivalent structure) to all parts of the body, after which it is returned to the heart to repeat the process. The Three Major Types of Blood Vessels Arteries, Veins, and Capillaries Anatomy and Metallic Biomaterials MSc 202 - 202 When the ventricles contract, atrioventricular valves close to prevent blood from flowing back into the atria. When the ventricles relax, semilunar valves close to prevent blood from flowing back into the ventricles. E- The urinary system : The urinary system's function is to filter blood and create urine as a waste byproduct. The organs of the urinary system include the kidneys, renal pelvis, ureters, bladder and urethra- The kidneys remove urea from the blood through tiny filtering units . 2- Two ureters:These narrow tubes carry urine from the kidneys to the bladder. Muscles in the ureter walls continually tighten and relax forcing urine downward, away from the kidneys. 3- Bladder This triangle-shaped, hollow organ is located in the lower abdomen. The bladder's walls relax and expand to store urine, and contract and flatten to empty urine through the urethra. |
