Published	02/10/2024	Pumps of the left and right heart are {{c1::in series}}, therefore the output must be equal
Published	02/10/2024	Function of Vasculature being In-Parallel:{{c1::All tissues get oxygenated}}{{c1::Allows regional redirection of blood}}
Published	02/10/2024	Total cardiac output is {{c1::5L}}
Published	02/10/2024	Explain {{c2::Darcy's}} Law{{c1::Flow through any vessel is proportional to the pressure difference and inversely proportional to …
Published	02/10/2024	Pressure Difference = {{c1::Mean Arterial Pressure}} - {{c1::Central Venous Pressure}}
Published	02/10/2024	Resistance of a vessel is controlled by {{c1::radius4}}, the relation between them is {{c1::inversely proportional}}.
Published	02/10/2024	Because flow is inversely proportional to resistance, → 2-fold increase in radius decreases resistance by {{c1::16-fold}}→ fl…
Published	02/10/2024	{{c1::Arterioles}} are vessels that act as 'the taps,' which are the driving vessels that control resistance (and therefore flow) to each vascular bed
Published	02/10/2024	Hierachery of Arterial Vessels (From Large to Small){{c1::Arteries}} → {{c1::Arterioles}} → {{c1::Capillaries}}
Published	02/10/2024	The highest pressure in the vessels of the cardiovascular system is found in the {{c1::aorta}} and {{c1::systemic arteries}} as they receive blood fro…
Published	02/10/2024	{{c1::Venous Capacitance}} is {{c2::the ability of the venules and veins to store blood. They can store up to 2/3 of blood volume, which allows contro…
Published	02/10/2024	Explain {{c2::Poiseuille's}} Law:[1] {{c1::Length: resistance to fluid flow offered by a tube increases as the length of…
Published	02/10/2024	If the pressure gradient remains {{c1::constant}}, then flow varies inversely with resistance.
Published	02/10/2024	Describe the following:Vessel: {{c1::Aorta}} Features:[1] {{c2::Elastic Artery}}[2] {{c2::Widest Lumen (Low resistance)}}
Published	02/10/2024	Describe the following:Vessel: {{c1::Muscular Arteries}} Features:[1] {{c2::Wide Lumen}}[2] {{c2::Strong Non-Elastic Walls}}

Published	02/10/2024	Describe the following:Vessel: {{c1::Venules and Veins} Features:[1] {{c2::Wide Lumen}}[2] {{c2::Capacitance vessels which act as a blood reservo…
Published	02/10/2024	{{c1::Papillary muscles}} are cardiac structures that are attached to {{c2::Chordae tendinae}} which prevent the tricuspid and mitral valves from inve…
Published	02/10/2024	Structure of the HeartChambers{{c1::Septum}} is {{c2::a structure that separates the left and right sides of heart}}{{c1::Myocardium}} is {{c2::the&nb…
