The topic of the assingment is to answer the questions in the worksheet that I will upload - Assignment Example

Biology The function of the red blood cells is to carry oxygen to the tissues of the body. The purpose of white blood cells is to offer immunity to the body.2. The main function of capillaries is to supply nutrients and oxygen to tissues. 3. Blood leaves the heart through the aorta. Aorta forms arteries that form arterioles, then capillaries. Capillaries supply oxygen and nutrients where tissues are. Deoxygenated blood and metabolic wastes are carried through venules, then through veins, and enter the vena cava’s to drain into the right atrium.

Blood from the right atrium enters right ventricle, and from there is pumped through the pulmonary artery to lungs to get oxygenated. From lungs, blood returns via pulmonary vein to the left atrium, through left ventricle and finally pumped via aorta.4. Heart valves close during systole5. Left Ventricle is thicker because it pumps oxygenated blood throughout the whole body with a lot of pressure6. You are hearing the combined work of a process of systole and diastole in action.7. Approximately 75ml8.

Systole refers to heart contraction and diastole refers to heart relaxation9. They begin the Sino atrial node found in the right atrium10. Cardiologists can provide antiarrhythmic drugs, heart failure drugs, to patients with cardiac problems. In addition, procedure like placing cardio converters, placing prosthetic valves, and pacemakers can be helpful in improving the quality of life of a patient11. Arterial plaque form in the blood due to deposition of bad cholesterol on the blood vessels. Arterial plaque formation in the heart can predispose it to heart attack.12. MEF2A is an autosomal gene majorly predisposing an individual to myocardial infarction and coronary artery disease.13. The ultimate goal of studying the gene is to come up with preventive measure to such individuals14.

HDL refers to High density lipoprotein. Raising its level is cardioprotective.15.
