How does oxygen enter the human body?
oxygen (O2) enters the body via respiration (breathing) it enters small pouches in the lungs called alveoli. these alveoli are surrounded by tiny blood vessels called capillaries. there is an exchange at these alveoli, carbon dioxide (CO2) exits the blood and O2 enters the blood. this freshly oxygenated blood is now returned via the pulmonary vein to the Left side of the heart. the left ventricle pumps blood to the body. as the blood vessels get smaller they again form capillaries. there is another exchange of gasses, O2 is transferred out to the cells and CO2 (the waste product from cellular metabolism) is transferred to the blood. the Deoxygenated blood is then returned via the venous system to the right side of the heart. the deoxygenated blood is pumped back to the lungs and the alveoli via the pulmonary artery. and then the whole cycle starts over again.hope this helps :)
How is co2 removed from the body?
We find that carbon dioxide is removed from the body via what is called gas exchange in the lungs. When we inhale, air is drawn into the lungs, and the alveoli in the lungs are the sites where gas exchange takes place. Carbon dioxide exits the blood, and oxygen enters. When we exhale, the carbon dioxide is carried out of the body, and the process is repeated with another breath.
How does water and air exchange take place in a leaf?
This all happens in photosynthesis. During the course of day in sunlight, the leaves absorb carbon dioxide from air holes present in them called stomata. The carbon dioxide is utilized to obtain energy with sunlight, and water. Then during night time, the trees starts giving of oxygen and water vapor as the waste products.
How do autotrophs obtain CO2 and N2 to make their food?
Autotrophs obtain CO2 from the air through stomata in their leaves and absorb N2 from the soil through their roots. They use these substances along with sunlight to perform photosynthesis and generate their own food.
What is the hypothesis of osmosis lab elodea leaf?
The hypothesis of an osmosis lab with an Elodea leaf could be that the Elodea leaf will lose water and shrink when placed in a hypertonic solution due to water moving out of the leaf cells by osmosis, causing the cells to become flaccid. Conversely, if the Elodea leaf is placed in a hypotonic solution, it may gain water, swell, and become turgid as water moves into the leaf cells via osmosis.
CO2 enters and 02 escapes from a leaf via?

How does carbon dioxide and water reach the chloroplast in leaves?
The chloroplasts in the leaves absorb the light directly from the sun. The carbon dioxide goes into the leaves through the stomata (tiny holes on the bottom of a leaf) and is diffused through the rest of the cells. The water is absorbed by the roots then carried by the xylem up to the leaf and the cells in the leaf.
How does oxygen enter the leaf?
Oxygen moves through leafy plants through the "stoma, pleural: stomata". They are small pores in the leaf that can open and close to allow gas exchange. However, most plants exhale oxygen (O2) and inhale carbon dioxide (CO2), so oxygen is generally leaving a plant.
Describe the path taken by water at the moment it enters the leaf and leaves through the stomata?
Water enters the leaf through the roots and moves up through the stem to the leaves via the xylem vessels. Once in the leaf, water moves through the mesophyll cells and eventually evaporates from the stomata as water vapor during transpiration.
What two types of cells are involved in the absorption of co2 and release of h2o from a leaf?
Absorption of CO2 occurs via photosynthesis; release of H2O is respiration: both occur in plant cells - the former only in light conditions and the latter continuously.
Contrast the manner in which water reaches the inside of a leaf with the manner in which carbon dioxide reaches the inside of a leaf?
It depends on the plant. If you're talking about, say, a tree, the water is carried up from the soil. That's why you water a houseplant. Carbon dioxide enters through holes in the bottom of the leaf called stomata.
Where does carbon dioxide enter in a leaf via holes?
the leaf!
How water travels through a leaf?
Water enters a leaf primarily through the roots via the xylem vessels, then moves up the stem to the leaf through a process called transpiration. Once in the leaf, water evaporates from the stomata on the leaf surface, creating a negative pressure that pulls up more water from the roots through the xylem. This continuous flow of water through the leaf helps transport nutrients and maintain cell turgidity.
Which class of nutrients enters the body via the lymph?
lipids
How does the oxygen get into cells?
oxygen (O2) enters the body via respiration (breathing) it enters small pouches in the lungs called alveoli. these alveoli are surrounded by tiny blood vessels called capillaries. there is an exchange at these alveoli, carbon dioxide (CO2) exits the blood and O2 enters the blood. this freshly oxygenated blood is now returned via the pulmonary vein to the Left side of the heart. the left ventricle pumps blood to the body. as the blood vessels get smaller they again form capillaries. there is another exchange of gasses, O2 is transferred out to the cells and CO2 (the waste product from cellular metabolism) is transferred to the blood. the Deoxygenated blood is then returned via the venous system to the right side of the heart. the deoxygenated blood is pumped back to the lungs and the alveoli via the pulmonary artery. and then the whole cycle starts over again.hope this helps :)
Does blood enter the lungs via the pulmonary artery?
Yes, the blood enters the lungs via pulmunery artery
