Function of Structures Aorta: Pumps blood out of the left ventricle after it is oxygenated into arteries that travel throughout the body. Arteries: Takes oxygenated blood to different parts of the body. Arterioles: Small tubes that extend off of the arteries that carry blood to the tissues. Atrium: Upper cavity of the heart that receives blood from the vena cava's and the pulmonary valve and pumps it to the ventricles.
Function of Structures Blood: Responsible for transporting oxygen, carbon dioxide, wastes, and nutrients throughout the body. Capillaries: Small vessels that connect veins and arteries. Heart: Main structure of the cardiovascular system. Receives blood from veins and pumps it to the lungs to be oxygenated, then gets it back from the lungs and pumps it to the body. Superior Vena Cava: Takes blood into the heart from the upper half of the body.
Function of Structures Vein: To pump deoxygenated blood back to the heart to be oxygenated. Ventricle: Lower chambers of the heart that pump blood to the lungs and then to the body. Venules: Allow deoxygenated blood to return from the capillary beds to the veins.
Diabetes Effect on System Blood vessels can become damaged. – Blood can’t flow correctly to all parts of body. Can cause swelling and discolored limbs Raises the risk for hypertension and atherosclerosis.
Sickle Cell Anemia’s Effect on System Sickled Cells are misshapen, which means they can’t carry oxygen correctly and block blood vessels. – This affects oxygen delivery to limbs and your heart rate, as it has to work harder to pump more oxygenated blood.
Heart Disease’s Effect on System Heart is worn down because of over use. – High/Low blood pressure – Heart failure – Heart may not work properly and can’t oxygenate blood correctly.
