BIO 202 Exam 1 Study Guide: Heart, Blood,
Endocrine Systems, & Hemostasis
, lOMoARcPSD|517 625 48
Topics of Endocrine, Blood, The Heart, and Vasculature
Focus on understanding like endocrine (hormonal regulation, normal arises, antagonistic hormones) blood (formed elements,
what makes a red blood cell, hemoglobin (know what the spleen RBC graveyard/breakdown and liver holds onto the iron
are involved), clotting, coagulation, clotting proteins, blood typing, antigens, why transfusion happen, who would get what),
Heart (disseminated coregulation, electrophysiology, difference between pacemaker (slow Na fast Ca), SA node, AV node,
where valves are and know they prevent backflow, calculate stroke volume and cardiac output) Vasculature (blood pressure,
renin, hormonal effects, understand resistance and what contributes, capillaries, when end is which at the end of chapter).
How would you tell the difference between artery and vein?
Coagulation cascade
Roman numerals are proteins, only triggered when damaged
inside the vessel - platelets trigger the cascade
Ca is needed in all steps

Vasculature
Muscular Arties
- Elastic arteries give rise to muscular arteries.
- Also called Distributing arteries, they deliver blood to body organs
- Diameter: pinky size to pencil lead size
- Thickest tunica media with more smooth muscle , but less elastic
tissue
- Tunica media sandwiched between elastic membranes
- ACTIVE in VASOCONATRICTION
Arterioles
- smallest of all arteries
- larger arterioles have all 3 tunics
- smaller arterioles single layer of smooth muscle surrounding endothelium cells
- Control flow into capillaries beds (VASODILATION & VASOCONSTRICTION of smooth muscle)
- Also called Resistance Arteries, changing diameters change resistance to blood flow; friction between blood
and vessel wall
- Lead to capillary beds
