Phlebotomy refers to a collection of venous blood. This operation can be practiced on all the superficial veins of the body, on those of the foot, the leg, the neck, the whole upper limb. It must be done in an area where there is a protruding vein and the least sensitive to limit pain to the patient. It should not be done in an altered, injured or infected area (like bruise)
The blood is collected on tubes with or without anticoagulant according to the analyzes that one wants to practice.
The reason for choosing the sampling site is for the most part practical, the veins are easily identifiable, and easily accessible for paramedical personnel. Their collection is less dangerous than that of arteries, which are generally thinner and close to the peripheral nerves.

Plants get carbon dioxide from the air through theirleaves<span>. The carbon dioxide diffuses through small holes in the underside of the leaf called stomata. (One of these holes is called a stoma. The plural is stomata</span>
Answer:
The water cycle uses plants for uptake of water and transpiration from the surface, so that water can be sent to the atmosphere.
Carbon cycle uses plants for uptake of CO2, by which it is removed from the atmosphere (and sent back to atmosphere when the plant is dead).
Explanation:
Both the cycles use plants as an integral component. Both the water cycle and carbon cycle use subsurface for long term storage. The water forms groundwater and can be stored for long duration. Similarly, carbon is stored in rocks for long term.
