Explanation:
Answer:
Ben will have to focus on his upper body strength, he will have to do push-ups, bench pressing, shoulder presses, etc... His duration of practice and upper body will need more work since average humans use their legs more than their own hands, so Ben would need to completely give in his time for this. Ben and Janine will both have different diets as well because of the different body parts trained. Janine on the other hand, will need to focus on lower body strength and flexibility, because rollerblading depends on perfect balance and flow, she would need to do squats, leg stretches, kicks, jumping jacks, etc... Her duration during practice and lower body building would be less than Ben depending on her determination but generally it would be less since lower body building comes with ease because as I said the average humans use their lower bodies more than upper. Thats pretty much it. I hope it helps and I tried my best!
Explanation:
Answer:
A. . Blood from the veins enters the ventricles.
C. Atria push blood into the ventricles
Explanation:
Blood enters the heart through two large veins, the inferior and superior vena cava, emptying oxygen-poor blood from the body into the right atrium of the heart. As the atrium contracts, blood flows from your right atrium into your right ventricle through the open tricuspid valve.
1. The right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle through the tricuspid valve.
2.The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve.
3. The left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle through the mitral valve.
4. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body.
