Structure and Function of the Cardiovascular System

Bertha is 81 years old, and was admitted to the hospital after contracting community-acquired pneumonia. She had been bedridden for 3 days, so her nurse arranged for a physiotherapist to assist her out of bed to help her slowly regain her mobility. Bertha decided not to wait for the physiotherapist, and after arising in the morning, she eased herself out of the bed and stood up. Suddenly, Bertha’s vision dimmed, and she felt light-headed and dizzy. A passing nurse saw her fall back to the bed and rushed to help her. The nurse comforted Bertha, and then suspecting orthostatic hypotension, went to find a sphygmomanometer to check her blood pressure.

Prolonged bed rest decreases plasma levels and vasomotor tone, which can both lead to orthostatic hypotension. How do changes in vascular resistance and radius affect blood flow? Assuming Bertha is otherwise healthy, how does her heart activity change to compensate for the orthostatic hypotension she experienced?
Considering the venous circulation, how is blood from the lower extremities returned to the heart?
Why did Bertha’s capillary fluid pressure (or hydrostatic pressure) change when she moved from a lying to standing position?

The Loss of the Creature versus the Souls of Black Folk

The Walker Percy article “The Loss of Creatures” depicts the experience experienced by every individual as a genuine encounter that is driven by their wants, or encounters experienced by specialists ahead of time. Percy accepts that individuals can gain just from encounters of simply close to home want instead of encounters that the specialists had previously established inclinations. Percy clarified the “loss of power” as a preconceptive idea of encounters with the assistance of specialists. W.E. B Du Bois, then again, composed an article entitled “The Soul of the Black Man”, which is incongruent with the expression “loss of power”.

W. E. B. Dubois’ great “dark soul” in 1903 investigates the philosophical and otherworldly parts of the “spirit” feeling that intently connects dark spirits and blacks with individuals of color. Dubois made two corresponding outings. One is to analyze the foundations of African American strict idea and the other is to assess African American culture network. A dark soul fuses holy and mainstream things and gives perusers an artistic model of “profound love” to communicate and orchestrate the beliefs of war of the “spirit” of African Americans.

The analysis of Dubois against the religion of African-Americans is projecting the inquiry “where did you discover the spirit of the dark of the twentieth century?” It happened that Duchais demanded the majority of the individuals of color, and now “looking for new strict beliefs at a brilliant night” (149). I might want to recommend that Dubois finds a consecrated and common genuine dark soul inside and out. It advances the manageability and progression of African-American social networks. The result of this network, “tragic melody”, or the soul of African American, Dubois, “the best endowment of the Negro” (181)

Through this intriguing personal record, the peruser can comprehend different contemplations of the dark soul in Dubois old style text. “Soul” must be established in certain strict standards. For some ages, African Americans attempted to demonstrate that they have a spirit that can acknowledge Christian ‘s deliver. What’s more, I needed to advance social situation as a slave as an individual. Be that as it may, for Dubois, “soul” is more than simple immaterial strict substance we can not see. “Soul” is a dark network in the country zone of ​​Tennessee State, “Soul” is a melody of distress prompting the opportunity of bondage, “Soul” is a sonnet remembered for Sunday messages, “Soul” is an existence of the world. , Recognition of networks identified with one another among work and love. It is a “spirit” which makes an essayist utilize a pen to communicate what he can not communicate in words.
