Document Summary

Lecture 7 the heart: cardiac muscle and cardiac action potential. Chapter 15 blood flow and control of blood pressure. To achieve this: overview of the cardiovascular system, understand cardiac muscle biochemistry. Consider heart as a functioning pump in closed system: understand pressure volume flow resistance (guiding physical properties that determine blood flow and blood pressure) To understand the basic sciences of the heart. Describe the structures of the heart and cardiac muscle. Main functions of the circulatory system: transport and distribute essential substances to the tissues, remove metabolic byproducts, adjustment of oxygen and nutrient supply in different physiologic states, regulation of body temperature (cid:858)hu(cid:373)oral(cid:859) (cid:272)o(cid:373)(cid:373)u(cid:374)i(cid:272)atio(cid:374) It(cid:859)s a tra(cid:374)sportatio(cid:374) s(cid:455)ste(cid:373) we want to bring and distribute metabolic wastes, cell needs, efficiently: we (cid:449)a(cid:374)t to re(cid:373)o(cid:448)e a(cid:374)(cid:455)thi(cid:374)g that(cid:859)s (cid:271)ad for the s(cid:455)ste(cid:373) The primary function of the cardiovascular system is the transport of materials to and from all parts of the body.
