The Anatomy And Physiology Of Blood Vessels Essay

Circulation 1. Compare and contrasts the anatomy and physiology of blood vessels: arteries, veins and capillaries. Why are these differences significant in the overall function of the circulatory system? Please be specific. The arteries are thicker and more elastic because of the fast pumping of blood that leaves the heart to other organs to the body, as where the veins are small due to the low blood flow because of the slow movement from the capillaries to the veins not like the forceful pumping from the heart to the arteries to the rest of the body. The Oxygenated blood goes through the arteries except the pulmonary arteries. Then Deoxygenated blood goes through the veins except the pulmonary veins. The lumen of the artery is narrow, were as the lumen of the veins is wider. There are not valves in the arteries, were as the valves are present in veins. In the arteries, endothelial cells of tunica intima are more long then wider, and have more elastic membrane that is more developed. Then the Tunica media is more muscular, and the tunica extrema is not as developed. In veins, the endothelial cells of tunica intima are not as long and have more elastic membrane then being developed. The Tunica media is l ess muscular were the tunica extrema is more developed. Arteries are deep within and the veins are more superficial. Capillaries are microscopic vessels; they carry blood from the arterioles then go to the small veins or venules. The wall of the capillary made up of aShow MoreRelatedAnatomy And Physiology And Describe Their Subdivisions942 Words   |  4 Pages1) Define anatomy and physiology and describe their subdivisions. - Anatomy studies the structure of body parts and their relationships to one another. Body structures can be seen, felt, and examined closely. - Gross, or macroscopic, anatomy: Study of large body structures visible to the naked eye, such as the heart, lungs and kidneys. - Regional anatomy, all the structures (muscles, bones, blood vessels, nerves, etc.) in a particular region of the body, such as the abdomen or leg, are examinedRead MoreVascular Lymphatic System And Atherosclerosis1280 Words   |  6 PagesJazmin Fontan Bryant Stratton College AHLT120: Anatomy and Physiology-1 Dr. Pamela K.

Having restriction of blood flow develops damage to a patients’ organs and also increases the risk of heart attacks, blood clots, and strokes overtime (WebMD, 2015).

This essay aims at using one cell necessary for life and discusses its properties of life, the core chemical terminology, its molecules, and compounds. Specifically, the assignment will describe the basic anatomy and physiology of the cell, how the cell respiration, photosynthesis, and reproduction occur in a concise manner. The paper will also discuss Mendel’s Laws as well as the DNA structure and function of the cell. Finally, the paper will conclude by discussingRead MoreBlood Pressure Regulation1269 Words   |  6 PagesBlood pressure regulation and changes occurring after increase in blood pressure Each time the heart pumps, it sends blood all over the body to supply organs and tissues with oxygen and nutrients. The strength of the force created as the heart pumps blood into the vessels together with the vessels’ resistance to the blood flow is defined as the body’s blood pressure (Darovic, 2002). A normal range blood pressure (BP) must be between 100-130mmHg systolic (when the heart is beating) and 60-90mmHgRead MoreHomeostatic Mechanisms That Maintain Body Fluid Levels Essay4196 Words   |  17 PagesTransport- requires protein carriers that join together reversibly with the substances to be transported across the membrane using (ATP) to energize its protein carriers also known as solute pumping Ref:Marieb, Elaine, N, Essentials of Human Anatomy and Physiology, Pearson, International, Edn, 9th, 2009, ppg, 76,78 Which is the most important electrolyte for the maintenance of osmosis pressure and volume in the extracellular fluid (ECF) compartment?

Thereafter the receptors in the blood which are chemoreceptors detect the change of pH. A message gets sent by the chemoreceptors by a sensory neurone to the brain. The sensory neurone connects to the relay neurone which then sends a message through the motor neurone away from the CNS. Thereafter the cardiac muscles contract more and the blood vessels dilate causing more blood to flowRead MoreHomeostasis: Feedback and Body1616 Words   |  7 Pagesinside the cells, one third of it fills the narrow spaces outside the cells. That fluid is identified as the extracellular fluid. (Guyton Hall, 2006). Extracellular fluid is always in constant motion, travelling throughout the body in the circulating blood. Ions and nutrients that make up the extracellular fluid are needed by cells to sustain cell life. Hence, all cells in essence live in the same environment – the extracellular fluid. In addition, the proper functionality of body cells is also highly
