<span> How does pulmonary circulation work? In my example below, we will start with the blood not reaching the heart yet. The heart beats around 75 beats a minute. Deoxygenated blood is in the veins, going to the heart. Note that veins will always carry deoxygenated blood, excluding the pulmonary veins. The deoxygenated blood goes into the heart through the superior or inferior vena cava, and goes into the right atrium. It then gets pumped into the right ventricle, and gets pumped through the pulmonary arteries to the lungs to get oxygenated. The blood, now oxygenated, comes back to the heart through the pulmonary veins, into the left atrium. The blood gets pumped from the left atrium to the left ventricle, where it gets pumped through the aorta to all of the body systems. The red blood cells travel through capillaries, which is where most of the gas exchange occurs between body cells and red blood cells. Red blood cells have no nuclei. When the red blood cells are no longer red, but blue due to lack of oxygen, they go back to the heart to get pumped to the lungs, and enter the heart through the superior or inferior vena cava. The cycle starts over. Just like the veins, arteries always carry oxygenated blood, excluding the pulmonary arteries. Also, the right side of the heart will have deoxygenated blood, or blue blood, and the left side of the heart will have oxygenated blood. </span>
Answer: a light source (sun) and water
Explanation:
The correct answer to your question is C- Negative Ion.
Answer:
a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one, thus equalizing the concentrations on each side of the membrane.
Explanation:
Answer:
The correct answer is: 1,4' linked polymers of D-glucose which differ in the stereochemistry of this linkage.
Explanation:
Cellulose and amylose are both polysaccharides and polymers of glucose (which means that they are composed of glucose molecules). While cellulose is mostly found on the cell wall of plants and algae, amylose (along with amylopectin) form the main carbohydrate in humans' diets: starch.
While the glucose molecules in <u>amylose are linked by α(1-4) glycosidic bonds</u>, the glucose molecules in <u>cellulose have β(1-4) glycosidic bonds</u>. This particularity is what makes amylose and cellulose compounds differ from one another.
