The cardiovascular system is made up of the heart and blood vessels‚ which are divided into arteries‚ veins and capillaries. The blood delivers nutrients and oxygen to the cells in the body. The arteries carry blood away from the heart and the veins carry it back to the heart. Capillaries are found in the muscles and the lungs‚ they have valves to stop the blood flowing backwards and this is also where gaseous exchange takes place. The heart works as a pump that pushes blood to the organs‚ tissues

The stereotypes of mechanics will always be there. There are a lot of things that people label mechanics unjustly for such as‚ they tend to believe that we as mechanics’ are all stupid and un-educated‚ that we all are grease monkeys and we want nothing more than

The Central Nervous System or (CNS) is located in the center portion of the body as its name implies. The (CNS) is made up of the brain and the spinal cord. Our brain is in control of many very important body functions and sensations like these for example: sleep‚ muscle movement‚ memory‚ sexual activity‚ emotions‚ hunger and thirst. Our spinal cord extends several types of nerve fibers from the brain acts like a switching and relay terminal for the peripheral nervous system as is stated in Mosby’s

Respiratory disease Respiratory disease is a medical term that encompasses pathological conditions affecting the organs and tissues that make gas exchange possible in higher organisms‚ and includes conditions of the upper respiratory tract‚ trachea‚ bronchi‚ bronchioles‚ alveoli‚ pleura and pleural cavity‚ and the nerves and muscles of breathing. Respiratory diseases range from mild and self-limiting‚ such as the common cold‚ to life-threatening entities like bacterial pneumonia‚ pulmonary embolism

Respiratory System: Study Guide The respiratory system provides for exchange of oxygen and carbon dioxide of the body. - In terrestrial vertebrae’s‚ the respiratory system includes 3 steps: 1. Breathing: Inspiration (inhaling oxygen) and Expiration (exhaling carbon dioxide) 2. External exchange- Gas exchange between the AIR and BLOOD in lungs. Blood then transfers oxygen to the tissue cells. 3. Internal exchange- Gas exchange between the BLOOD & TISSUE FLUID and between the CELLS & TISSUE FLUID
