2.When the aortic valve opens into the aorta, blood flows: out to the body, into the right atrium, into the left ventricle, or o
ut of the pulmonary artery 4. How can an automatic external defibrillator (AED) save a person’s life?
5.How does high blood pressure affect the heart?:High blood pressure forces blood from the atria into the ventricles. High blood pressure forces blood from the ventricles into the atria. High blood pressure creates excessive force on the blood vessels, weakening them.High blood pressure causes the heart muscle to contract before the atria fully fill with blood.
13.How does obesity affect the joints?:Being obese provides more cushioning for the joints and protects them from harm.Being obese cuts off circulation to the joints and damages the blood vessels around them.Being obese places extra stress on the joints and makes it more likely a joint replacement will be needed.Being obese creates more metabolic wastes, which attack the cartilage between joints and make it more likely a joint replacement will be needed
15.What does the medical community recommend to prevent obesity?:Take in fewer calories than the body burns during physical activity and metabolism.Avoid anyone infected with adenovirus-36.Eat foods that are fat and gluten free.Eat a diet high in protein and carbohydrates.

23.Which of the following was required before widespread organ donation could be successful?
24.What mechanism causes organ rejection in transplant patients? 25.Which of the following could eliminate the need for immunosuppressant drugs?
2. When the left ventricle relaxes, the aortic valve closes and the mitral valve opens. This lets blood flow from the left atrium into the left ventricle.
4. Quickly shocking the heart with an automated external defibrillator (AED) can save a person's life after cardiac arrest. An AED is a portable, battery-operated device that a bystander can use. It checks the heart rhythm and can send an electric shock to the heart to try to restore a normal rhythm.
5. High blood pressure can damage your arteries by making them less elastic, which decreases the flow of blood and oxygen to your heart and leads to heart disease. In addition, decreased blood flow to the heart can cause: Chest pain, also called angina.
Since there is no choices, I'm assuming it's an opinionated question. The best way would be to talk to them face to face. Upfront talks are better even if they may be scary or intimidating. Hope this helps!
