Answer:
a. systemic circulation
Explanation:
Systemic circulation, also called large circulation, is responsible for ensuring that oxygenated blood is carried throughout the body and that carbon-rich blood returns to the heart. Oxygenated blood leaves the left ventricle through the aorta, is carried to various parts of the body, undergoes gas exchange in the tissues and returns to the right atrium of the heart through the superior and inferior vena cavae. Upon reaching the heart, the carbon-rich blood is then taken to the lung for oxygenation, and the pulmonary circulation process begins again.
Answer:
Have you identified more activities that will need doing that might slow down your progress? Are your goals (and their timing) still realistic?
Explanation:
Answer:
1) Cheating.
2) Swearing.
3) Hostile Mood Swings.
Explanation:
At first, blood flows from the right atrium.
Then it goes into the right ventricle and through the tricuspid valve.
After that, when the ventricle is full, the tricuspid valve is there to shut to prevent blood flowing backwards into the atrium which can cause problems.
Then, blood leaves the heart through the lumonic valve and it goes into the pulmonary artery and then to the lungs.
