Materials pass to and from the bloodstream through the thin walls. They have walls that are only one endothelial cell in thickness. This delicate, microscopic vessel carries nutrient-rich, oxygenated blood from the arteries and arterioles to the body cells. There, the nutrients are burned in the presence of oxygen (catabolism) to release energy.
At the same time, waste products such as carbon dioxide and water pass out of the cells and into these blood vessels. Waste-filled blood then flows back to the heart in small venues, which combine to form larger vessels called veins.</span>carbon dioxideGas (waste) released by body cells, transported via veins to the heart, and then to the lungs for exhalation.coronary arteriesBlood vessels that branch from the aorta and carry oxygen-rich blood to the heart muscle.deoxygenated bloodBlood that is oxygen-poor.diastole<span>Relaxation phase of the heartbeat.</span>

Answer:
The correct answers are B and C. The tsunami waves were as high as 500 feet, and it was triggered by a 9.1 magnitude earthquake.
Explanation:
The 2004 Indian Ocean tsunami was a series of tsunamis that swept the shores of most countries along the Indian Ocean on December 26, 2004, killing almost 280,000 people. This is considered one of the biggest natural disasters in history. The tsunami was caused by a huge 9.1 magnitude earthquake that shook the underwater off the west coast of Sumatra. This was the third largest earthquake measured by a seismometer. The ensuing tsunamis reached a height of 30 meters in some places when they made landfall. It has been confirmed that 131,028 people have died in Indonesia. More than 30,000 died in Sri Lanka and thousands died in India and Thailand. In Somalia, 4,500 km from the epicenter, 176 people were killed and about 50,000 people lost their homes. $ 14 billion in emergency aid was collected for the worst-affected countries.
