Explain how the circulatory system is able to transport the blood under high pressure from the heart to the rest of the body
expeople1 [14]

Transport of blood under high pressure is done through the concerted efforts of the heart and arteries.

<h2>The circulatory system is the network of the heart, arteries, veins, and capillaries responsible for the movement of blood around the body.</h2>

Transporting blood under high pressure can be explained in the following steps:

  1. Contraction of the heart ventricles creates blood under high pressure
  2. High pressured blood is removed from the heart through the arteries. In addition, the arteries are able to contract and expand, thus are elastic
  3. The lumen of the arteries is narrow thus helping in maintaining high pressure

As a result of the above, the high pressure of blood is maintained and transported to the extremities of the body.

Which of the following is NOT true about the cohesion-tension model of water transport?Select one:a. Water must completely fill
aksik [14]

Answer:

d. Water is transported in the phloem.

Explanation:

Xylem is the vascular tissue responsible for the movement of water and dissolved minerals from roots to various plant parts. Phloem is another vascular tissue that serves mainly in the translocation of sugars. The cohesion-tension model of water transport explains that the upward movement of water from roots to the aerial plant parts is drive by transpiration pull. Transpiration of water from leaves results in a large negative pressure in xylem elements. Cohesion and adhesion properties of water maintain the water column in xylem elements.
