Blood is delivered to bodily tissues through:
arterioles |
|
veins |
|
capillaries |
|
plasma |
The aorta is the body's largest artery and receives blood from the pulmonary vein via the left ventricle. From there, blood is circulated through the rest of the body through smaller arteries called arterioles that branch out from the heart. Finally, blood is delivered to bodily tissues through capillaries.
Examples of primary consumers include:
all of these |
|
rats |
|
cows |
|
fish |
Primary consumers (herbivores) subsist on producers like plants and fungus. Examples are grasshoppers, cows, and plankton.
In fermentation, what replaces oxygen in anaerobic respiration?
water |
|
ascorbic acid or peptides |
|
lactic acid or alcohol |
|
starches |
If no oxygen is present, cellular respiration is anaerobic and will result in fermentation where either lactic acid or alcohol is used instead of oxygen.
What prevents blood pumped out of the ventricles from flowing back into the heart?
platelets |
|
valves |
|
capillaries |
|
atria |
The heart is the organ that drives the circulatory system. In humans, it consists of four chambers with two that collect blood called atria and two that pump blood called ventricles. The heart's valves prevent blood pumped out of the ventricles from flowing back into the heart.
The two heart chambers that collect blood are called:
ventricles |
|
atria |
|
valves |
|
aorta |
