The xylems in plants are vessels, starting with the root of the plant where water and minerals are absorbed and efficiently carry the water throughout the body of the plant. The xylem also provides support to the plant. Nutrients or sugars produced through photosynthesis need to be sent to every cell in the plant, phloem makes this possible. Phloem lives as long as the plant while xylems function for one year. The xylems of a plant can be seen when a tree is cut the rings of the xylem can be seen also telling the age of the tree, each ring represents one year.
The heart in humans pumps the nutrient rich blood throughout the human circulatory system via blood vessels. The blood vessels pump the blood throughout the body allowing oxygen, nutrients, and hormones to be picked up in the lungs, intestines, and endocrine system. The various blood vessels in the human body then make a delivery to each cell in the body. The blood vessels then head back to the heart, on the way back carbon dioxide and waste is picked up to be exerted.
Plant and animal circulatory systems are high functioning. Plants rely on gravity and water surface tension to transport nutrients throughout the body of the plant, humans need a pumping heart to continuously pump blood throughout the body. Plants and humans both have tube shaped vessels to carry the nutrients, water, blood throughout the
