“…Stroke volume is the difference between enddiastolic and end-systolic volumes and is determined by myocardial contractility and cardiac filling. Increased venous return raises end-diastolic volume, which increases contractility and stroke volume via the Frank-Starling relationship (Guyton, 1955;Guyton et al, 1955Guyton et al, , 1957Bishop et al, 1964), and it is well established that the venous system plays an important role in determining the rate at which venous blood returns to the heart in mammals (Guyton, 1955;Guyton et al, 1957;Rothe, 1986;Tabrizchi and Pang, 1992;Pang, 2000).…”

venous tone, adrenaline as well as phenylephrine and isoproterenol (␣ ␣-and ␤ ␤-adrenergic agonists, respectively) were infused as bolus injections (2 and 10· g·kg -1 ). Adrenaline and phenylephrine caused large increases in MCFP and P CV , whereas isoproterenol decreased both parameters. This was also the case in fully recovered snakes. Therefore, adrenaline affects venous tone through both ␣ ␣-and ␤ ␤-adrenergic receptors, but the ␣ ␣-adrenergic receptor dominates at the dosages used in the present study. Injection of the nitric oxide donor SNP caused a significant decrease in P CV and MCFP. Thus, nitric oxide seems to affect venous tone.

“…As overall vascular compliance is mainly dependent on the structure and function of the venous system, venous compliance is important for overall cardiovascular regulation [15]. High venous compliance means a high stretch and high ability to store blood [15,41]. Due to the compliant venous nature, small changes in venous tone might redistribute large volumes of blood from a venous pool to the arterial side of the circulation and in this way increase effective blood volume when needed [41][42][43].…”

Purpose: Leg venous compliance decreases with age, but subjects with high fitness show less venous remodelling than unfit subjects. Whether a high fitness level can counteract the normal age-decline in upper arm venous compliance is unknown. Study aim: First, to examine upper arm venous compliance across age in participants with comparable levels of maximal oxygen uptake (VO 2max ). Second, to examine if upper arm venous compliance is related to total blood volume. Methods: Twenty-eight healthy fit participants within the age groups 20-39 (young: VO 2max 3.44 (2.35-5.09) L•min -1 , n=9), 40-59 (middle-aged: VO 2max 3.08 (2.17-4.60) L•min -1 , n=9), and 60-69 (old: VO 2max 3.27 (2.24-4.04) L•min -1 , n=10) years of age were recruited to the study. Upper arm venous compliance was examined using high-resolution ultrasound and Doppler, while total blood and plasma volume were measured using the optimized carbon monoxide (CO)-rebreathing method. Results: No difference was found in upper arm venous compliance normalized to blood volume in participants aged 20-69 years (young: 0.22 (-0.02-0.5) mm 3 •mmHg -1 •L -1 , middle aged: 0.05 (-0.1-0.4) mm 3 •mmHg -1 •L -1 , old: 0.16 (0.1-0.5) mm 3 •mmHg -1 •L -1 )with comparable high VO 2max levels. Conclusion:In the studied subjects between 20-70 years old with comparable absolute VO 2max , upper arm venous compliance normalized to blood volume seems to be age independent.

“…Além do retorno do sangue para o coração, as veias desempenham papel importante na manutenção da hemostasia cardiovascular devido à sua capacidade de mudar de forma e manutençāo da pressão, apesar de alterações significativas no volume (Rothe, 1986). Em determinadas situações, o sistema venoso pode conter até 75% do volume sanguíneo sistêmico.…”
