What pumps blood toward the lungs where it exchanges carbon dioxide for oxygen?

Oxygen passes into the blood and carbon dioxide leaves it through the walls of the capillaries which surround the alveoli in the lungs. It's not really correct to use terms like 'pump' and 'collect', as this is a simple process of diffusion.

How are cardiovascular and respiratory system related?
The cardiovascular and the respiratory system both work toward the same goal: getting oxygen to tissues and getting carbon dioxide out. The respiratory system is involved in supplying oxygen to the blood and removing carbon dioxide. When the heart receives blood that is low in oxygen and high in carbon dioxide, it pumps it to the lungs via the pulmonary arteries. When the lungs expand and get fresh air from the environment, oxygen is transferred (via the alveoli) into the low-oxygen blood, which also then sends some of its carbon dioxide back into the lungs. Now that this blood has fresh oxygen in it, it returns to the heart and the heart then pumps it throughout the body.
How does carbon dioxide in the atmosphere affect earth's climate?
Carbon dioxide does occur naturally in our atmosphere, and is actually necessary for plant life. However, since the Industrial Revolution, carbon dioxide has reached dangerous levels. This causes a "greenhouse effect", which works like this:The sun's light hits the ground, and part of it reflects back into space. This is normal. However, the excess carbon dioxide in the atmosphere reflects it back to the ground, causing an increase in temperature. Even though the increase is less than one degree in average temperatures around the globe, it is enough to cause melting of the ice caps and affect the overall biosphere.
Why the water is stronger acidic than alcohol?
alcohols have methyl groups, ethyl groups ect... attached to the alcohol. Carbon and its hydrogens are considerd electron donating groups (because they are not electronegative like F, O or N); therefore they donate part of their electric charge toward the oxygen on the alcohol making that oxygen less able to distribute the electron from the lost hydrogen. Meanwhile, water can lose a hydrogen and does not contain any electron donating groups (such as Carbon) and the oxygen is better suited to distribute the extra electrons from the lost hydrogen. think about it... if carbon is donating part of its electrons to oxygen in an alcohol, there is less room for that oxygen to take on the electrons from a lost hydrogen vs water.
The four single bonds of a carbon atom are directed in space toward the corners of what?
A tetrahedron.
What is the molecular structure of ccl2o what type of bond is it?
The Lewis Structure of CCl2O is:1. Carbon atom in the middle2. Oxygen will form a double bond with Carbon and has 4 unshared electrons3. Both Chlorine atoms will form a single bond with Carbon and have 6 unshared electronsThe Formal Charge on each atom is 0 which means that this structure contributes the most to resonance.The VSEPR structure for this molecule is trigonal (triangular) planar and is polar with the more negative charge tending toward the Oxygen (more electronegative)
How does exchange of nutrients and oxygen with waste and carbon dioxide take place in the capillaries?
Pure diffusion ... everything flows from high concentration toward low. No energy is expended in these exchanges.

How are the cardiovascular and respiratory systems integrated?
The respiratory system draws oxygen into the lungs where the circulatory system exchanges waste gas (carbon dioxide) for oxygen. The respiratory system then expels the waste gas during exhalation, and the circulatory system delivers oxygen to cells throughout the body.
What system does the respiratory system relate to?
The cardiovascular and the respiratory system both work toward the same goal, getting oxygen to tissues and getting carbon dioxide out. The respiratory system is involved in giving oxygen to the blood and removing all the co2 . When the heart receives blood that is low in oxygen and high in carbon dioxide, it pumps it to the lungs. When the lungs get bigger and get air from the environment, oxygen is transferred into the blood with the low-oxygen , and some of the co2 comes back into the lungs. Now that this blood has good oxygen in it, it returns to the heart and the heart then pumps it throughout the body.
What is a leech's breathing organ?
Leeches do not have a separate respiratory system. They absorb oxygen through their cuticle (skin) and it diffuses throughout the leech's body. Carbon dioxide leaves via the same route - diffusion toward the cuticle where it will diffuse out.

What do you have to do to get more carbon dioxide to a plant?
Assuming that the plant has enough sunlight and is only being limited by low carbon dioxide, you can increase the local partial pressure of the gas, typically by having a number of people stand around and exhale toward it. Greenhouses have lower levels of carbon dioxide than outside air, but usually more than enough for the plants to perform photosynthesis.
What substances flow through the right atrium?
The right atrium receives "de-oxygenated" blood (blood from the body containing less oxygen and more carbon dioxide) and the right ventricle sends this blood toward the lungs.
What are the functions of veins?
To transport blood carrying Carbon dioxide and other waste products Through the body's organs so that they can be removed, making the blood ready once again for the transportation of nutrients and oxygen through the Artery's to the bodythey carry blood back to the heartthey carry deoxygynated blood towards the heart
