Genetics I think I maybe wrong ok
False.
Extinction = Behaviors that are not reinforced will become weaker (occur less often).
C. Analgesics Too much of these will cause liver disease
Short answer:
Valve which permits blood to flow from the right atrium to the right ventricle is tricuspid valve
Long answer:
The right side of the heart has lower pressure compare to the left side. There is a valve that support the lower pressure so the blood can move easily from the right atrium to the left ventricle. The valve is called tricuspid valve. It's called "Tri" because there are 3 flaps/leaflets on the valve.
For your information, the left side of the heart only has 2-leaflet valve, which make smaller circular opening compare to the 3-leaflet valve on the right side. That's because the left side has higher pressure than the right side.
Answer: What are the risk factors for cardiovascular disease?
About half of all Americans (47%) have at least 1 of 3 key risk factors for heart disease: high blood pressure, high cholesterol, and smoking. Some risk factors for heart disease cannot be controlled, such as your age or family history.
Signs and symptoms can include:
Chest pain, chest tightness, chest pressure and chest discomfort (angina)
Shortness of breath.
Pain, numbness, weakness or coldness in your legs or arms if the blood vessels in those parts of your body are narrowed.
Pain in the neck, jaw, throat, upper abdomen or back.
What treatment is used for cardiovascular disease?
Since the 1970s, aspirin has also been used to prevent and manage heart disease and stroke. Beta-blockers are one of the most widely prescribed class of drugs to treat hypertension (high blood pressure). They are a mainstay treatment for congestive heart failure.
