Task 2 Part A Cebita Santhosh
Q1. The three main types of blood vessels in the circulatory system are veins, arteries and capillaries. The veins carry deoxygenated blood from the capillaries back to the heart. The arteries carry blood away from the heart to your tissues. The capillaries are the smallest of the body's blood vessels, only one cell thick and are found in the muscles and lungs. Q2. Eating too much salt can raise your blood pressure because of the extra water stored in the body. The thicker the walls grow, they become less complaint and eventually are unavailable to pump forcefully as a healthy heart. The elasticity of vessels stiffens and lose their ability to easily expand. Q3. Oxygen and carbon dioxide are the two main types of gases within the lungs. Oxygen spreads from the air in the alveoli into the blood. Carbon dioxide spreads from the blood into the air in the alveoli. When you inhale, the diaphragm contract and when you exhale, the …show more content…
Bronchi, bronchioles and alveoli are the order from largest to smallest. The main function of the bronchi and bronchioles is to carry air from the trachea to the lungs. Bronchi are the main passageway into the lungs. The bronchioles are the passageway by which the air passes through. Alveoli are tiny sacs within our lungs that allow oxygen and carbon dioxide to move. Q5. Digestion begins in the mouth, where the food is cut and chopped up by your teeth. The tongue helps digest the food with a juice called saliva, which is a secreted by glands in the mouth. Saliva is important because you need it to digest food and it keeps your teeth strong. Q6. When food is broken down in the stomach, it forms a substance called chyme which is a slurry of nutrients. The cells of the villi and another part of the small intestine, transport food from the digestive tract into the bloodstream, where they can be used by the body. When the slurry passes into the intestine, it gets in contact with
