Explanation The pressure gradient, which is responsible for driving the flow of blood via tissue, and the resistance in a particular blood vessel to the blood flow are the two factors that influence the blood flow. The blood pressure is developed by the contraction of the ventricles. It is determined by CO. The blood, like every fluid and liquid, flows from ahigher-pressure region to a lower pressure region...

Chapter 18.2, Problem 2QC

Summary Introduction

To review:

The relations between the pressure gradient and the blood flow, as well as between blood flow and resistance.

Introduction:

The volume of blood that flows via a tissue in a particular period of time is called blood flow. The cardiac output (CO), that is, the blood volume that flows via the pulmonary (or systemic) blood vessels in a minute is the total amount of blood flow.

Discussion entries must be at least 250 words to fulfill the assignment requirements. You must complete your entry before you will be able to see the responses of other students. Responses to other students are encouraged but not required. Grading for discussion entries will be based on application of course concepts, proper grammar, and correct punctuation. Read one the attached article and explore the Human Development Index (https://hdr.undp.org/data-center/human-development-index#/indicies/HDI). In your opinion, is the Human Development Index a good measure of the well- being of the people of a nation? Are the items measured in the HDI valid and relevant in the modern global economy? How are they related to the political economy of a nation? The attached articles propose some alternative measures of well-being. In your opinion, are there other measures of well-being that might be better alternatives to the items in the current HDI?
