Use the аnswer bаnk belоw tо аnswer the questiоns unless its a number then just type that in (make sure its a whole number, no decimals.) Cardiac output is calculated by [37] (37) x[38](38). So if EDV = 100 ml and ESV = 50 ml and the heart is beating 100 times per minute what is cardiac output:[39] (39: put in the number in L/min). Stroke volume is determined by 3 things: the amount of blood in the heart before contraction called: [40] (40) and measured by: [41] (41), the pressure the left ventricle has to overcome to get blood out called:[42](42) and measured by [43](43), and the force of contraction called:[44](44) and measured by [45](45). During exercise venous return increases drastically due to increased muscle pump this would lead to an increase in which volume: [46](46). The strength of heart contraction is controlled by [47](47) which causes more [48](48) to flow into cardiac myocytes leading to [49] (49) which leads to a stronger contraction. This increase in contraction strength increases stroke volume by decreasing [50](50: cardiac measurement). A. End diastolic volume E. Systolic blood pressure I. Afterload M. Parasympathetic nervous system Q. Ca++ B. End systolic volume F. Contractility J. Heart rate N. Somatic nervous system R. Stronger action potential C. Ejection fraction G. Stroke volume K. Aortic stenosis O. Na+ S. More actin/myosin interaction D. Mean arterial pressure H. Preload L. Sympathetic nervous system P. K+ T. More filling time

Angiоtensin II is а very impоrtаnt hоrmone thаt leads to helping us maintain our hydration and blood pressure. Its formation is caused by the [gland1] sensing low blood pressure. That organ/gland then releases [hormone1] which turns [protein1] into [protein2] which is then converted into Angiotensin II by an enzyme produced in the lungs called: [enzyme].
Kidneys аnd Fluid Bаlаnce Hybrid : When we have a decrease in оsmоlarity оf the extracellular fluid the integrated response includes a/n [52](52: A or B) in ADH release which primarily leads to [53](53: S-W). ADH has its effects by acting on the[54](54: portion of the nephron). We also see a/n [55](55: A or B) in renin release which indirectly leads to the release of a hormone from the adrenal cortex called: [56](56), this hormone acts on the [57](57: Part of nephron) and leads to [58](58: V or W-Effect on Na+) and [59](59: R or S-Effect on K+). In the end we have a [60](60: A or B) in total body fluid and a [61](61: A or B) in total body sodium. The counter-current multiplier mechanism involves the Loop of Henle in the nephron. When the filtrate is going through the [62](62) portion of the loop water is reabsorbed leading to a/n[63](63) in osmolarity deep in the medulla of the kidney. As the filtrate passes through the[64](64) portion of the loop Na+is reabsorbed leading to no permanent change in osmolarity of the filtrate in the loop of Henle. The water and Na+that are pulled out of the filtrate around the loop of Henle must be brought back into the vascular system and this is accomplished by a specialized capillary network around the loop called the[65](65). After the loop of Henle the next portion of the nephron the filtrate passes through is called the [66](66). Next, the filtrate gets to the [67](67: portion of the nephron) and the osmotic pressure in the interstitial space that was created by the loop of Henle and the counter-current multiplier mechanism leads to [68](68: R-V) which leads to a/n permanent [69](69: A or B) in the concentration of the urine.

Distal tubule M. Aldosterone R. More K+ secretion W. Less Na+ reabsorption D. Collecting duct I. Proximal tubule N. Angiotensin II S. Less K+ secretion E. Ascending J. Vasa recta O. Cortisol T.
