_Cardiovascular regulation in women with vasovagal - DiVA

Davies et al (2007) were able to separate the aortic pulse pressure waveform into a forward pressure wave, a reflected backward pressure wave, and the arterial reservoir pressure. The elastic recoil of the arteries allows the artery to expand as normal but then exert an inward force to create blood pressure. The artery is slowly returning back to it's original shape which is continually 'maintaining' pressure. Ultimately the elastic recoil of the aorta is affected as well as the diameter of the aorta and its branches. Without blood being constantly propelled due to the loss of elasticity and not having a sufficiently wide passage to move through, there may not be enough oxygen-rich blood reaching every part of the body. This phenomenon is also reflected in the dynamics of the elastase model in which exposure to pure elastin does not immediately induce AAA formation 38 and in which the initial response following porcine pancreatic elastin preparations is a small increase in aortic diameter, presumably reflecting loss of elastic recoil.

Elastic recoil of the aorta

Thoracic Aorta (Chest Region): Abdominal Aorta: Celiac Artery: branches from the abdominal aorta into the left gastric, hepatic, and splenic arteries. Elastic walls of aorta are stretched as blood is ejected into the aorta from the left ventricle. - aortic pressure remains slightly below the ventricular pressure during this period. Step 2 of APC. 1. Blood flows back toward the ventricle because of the elastic recoil of the aorta. Ultimately the elastic recoil of the aorta is affected as well as the diameter of the aorta and its branches.

The characterization of disorder is consistent with an entropy-driven mechanism of elastic recoil. It is concluded that conformational disorder is a constitutive feature of elastin structure and function. specific histological composition of the aorta allows an elastic response to blood ejection, which consists in the circumferential stretching of its wall and the subsequent recoil. The aortic wall of the aorta (Co)(1-5).

Aortic pressure is highest at the aorta and becomes less pulsatile and lower pressure as blood vessels divide into arteries, arterioles, and capillaries such that flow is slow and smooth for gases and nutrient exchange. This stretching generates the potential energy that will help maintain blood pressure during diastole, when the aorta contracts passively.

The elastic recoil helps conserve the energy from the pumping heart and smooth out the pulsatile nature created by the heart. Aortic pressure is highest at the aorta and becomes less pulsatile and lower pressure as blood vessels divide into arteries, arterioles, and capillaries such that flow is slow and smooth for gases and nutrient exchange. Elastic recoil in arteries and veins Take rings of artery and vein tissue. Load and unload with 10 g masses and hence assess differences in elasticity. Consider how the elastic properties suit the different functions of artery and vein in the circulatory system.
