To answer: How do the structures of arteries, capillaries, veins, and lymphatics differ and how these differences reflect on each of its function?
Introduction: The transportation of oxygen and nutrients and exclusion of
Explanation of Solution
The arteries and veins possess three distinct layers. The primary tissue of the arteriole is made up of smooth muscles, whereas the veins are primarily made up of connective tissues. The smooth muscles of the arteries are found to be reflective with their capacity in order to withstand high pressures. Also, they respond to certain changes in the body by contraction or relaxation of the arteries.
The capillaries are made up of a single layer of endothelial cells that were attached to the basement membrane spacing between the endothelial cells. This would allow the entry of certain components to pass in and out of the capillaries thereby allowing the fluid and cellular exchange.
The lymphatic vessels possess thin valves and walls resembling that of the veins. These thin walls and valves aid in adsorption and flow of lymph through the lymphatic vessels.

- A classmate says that without specialized cells, the heart wouldn’t be able to help other organs and body system to perform. Based on your understanding of body organization, is there evidence to support her claim? (a) Yes, without red blood cells, the heart wouldn’t be able to deliver oxygen to other organs (b) somewhat, because the heart is constructed from specialized tissues, such as muscle tissue, that help it to function but the cells are no different than other body cells (c) no, this in inaccurate because it is the brain, not the heart that help the other organs in the body to function (d) No, because the cells in the heart are not specialized compared with other organs in the bodyarrow_forwardHow does the circulatory system transport oxygen and nutrients to the body's tissues?arrow_forward(a) Name the type of blood vessel labelled (i) C.
