Circulatory And Respiratory System

The circulatory and respiratory systems play vital roles in maintaining the body's health. The circulatory system is responsible for moving blood through blood vessels, with arteries carrying oxygen-rich blood away from the heart, while veins return deoxygenated blood. The respiratory system facilitates breathing, allowing the exchange of oxygen and carbon dioxide in the lungs. Key structures include the trachea, bronchi, and alveoli. Together, these systems ensure adequate oxygen supply and waste removal, crucial for cellular functions and overall well-being.

  2. Circulatory System - The circulatory system moves blood throughout the body- Blood vessels are the “roads” that the blood travels down - Arteries are blood vessels that carry blood away from the heart- Capillaries are a network of tiny blood vessels that act like a highway interchange- Venules carry deoxygenated blood back to the veins from the capillaries - Veins carry deoxygenated blood back to the heart http://www.biosbcc.net/doohan/sample/htm/COandMAPhtm.htm

  3. Respiratory System - The respiratory system helps you breathe in oxygen and exhale carbon dioxide- Lungs deliver oxygen for cellular respiration and excrete carbon dioxide- Cilia is tiny hairs that warm up sir when you breathe - Larynx contains vocal cords - Trachea is the air passage to the lungs - At the base of the trachea branch two tubes called the bronchi- Air goes from the bronci to two smaller tubes called bronchioles- Alevoli’s are tiny thin walled sacks- Gas exchange is when the blood makes a full circuit of the system- gets oxygen from the lungs and and gets pumped all the way around the body and back.- Smoking makes it hard to breathe and can lead to lung cancer http://www.bs757.com/2013/10/simple-ways-to-keep-your-lungs-healthy/

  4. Heart http://en.wikipedia.org/wiki/Heart - Heart pumps blood throughout the body- Atria moves blood from the body to the heart- Ventricles pump blood out of the heart

  5. Blood - Blood performs several functions necessary for your health - Plasma 55% of your blood is plasma, it is a clear fluid.- Red blood cells carry oxygen- White blood cells fight infection and prevent the growth of cancer- Platelets are important for clotting blood. They form a scab http://en.wikipedia.org/wiki/Red_blood_cell
