Answer:
C. Talk to an adult or mental health professional about how to help.
Explanation:
Evaluating your skills is a key component to a successful physical activity action plan. Assessing yourself through physical tests (e.g. weight and girth measurements) could give you an idea what exactly you want to happen in your training program. Aside from knowing your structure, you should also assess yourself if you are fit enough or you have certain medical conditions that would prohibit you from performing certain activities (e.g. high blood pressure, hypertension).
In doing so, you not only ensure the success of your training action plan, but you also secured your safety before executing the activities you assigned for yourself.
Answer:
Open tricuspid and mitral valves, Closed tricuspid and mitral valves, Open pulmonic and aortic valve, Closed pulmonic and aortic valves
Explanation:
Blood flows from the right atrium into the right ventricle through the open tricuspid valve, and from the left atrium into the left ventricle through the open mitral valve.
When the right ventricle is full, the tricuspid valve closes and keeps blood from flowing backward into the right atrium when the ventricle contracts (squeezes). When the left ventricle is full, the mitral valve closes and keeps blood from flowing backward into the left atrium when the ventricle contracts.
As the right ventricle begins to contract, the pulmonic valve is forced open. Blood is pumped out of the right ventricle through the pulmonic valve into the pulmonary artery to the lungs.
When the right ventricle finishes contracting and starts to relax, the pulmonic valve snaps shut. This keeps blood from flowing back into the right ventricle.
When the left ventricle finishes contracting and begins to relax, the aortic valve snaps shut. This keeps blood from flowing back into the left ventricle.
