1. In relation to cardiodynamics; stoke volume refers to the amount of blood pumped by the heart with each ventricle contraction. End systolic volume is the amount of blood remaining in the ventricle after at the end of systole. End diastolic volume the amount of blood at the end of diastole that each ventricle has filled up with.
Systemic Arterial Blood Pressure is the force of blood pressure on the arterial walls just after ventricular contraction. Cardiac output is the volume of blood ejected from the left or right ventricle into the aorta or pulmonary trunk per mind. Cardiac output equals stroke volume times the heart rate; therefore, if the anything that decreases cardiac output, also decreases blood pressure because there is less pressure on the vessel walls. An increase in cardiac output results in an increase in blood pressure. Anything that affects heart rate or stroke volume affects cardiac output and blood pressure.
Total Peripheral Resistance is a measure of the total resistance to blood flow provided by the entire vascular system. TPR plays a role in blood pressure, but it is more a defined measure of the cardiovascular system and not pressure against the arterial walls, which is a measure of blood pressure.
2. Frank-Starling Law of the Heart is the degree to which the ventricular walls are stretched by the returning blood determines the stroke volume. The more blood in equals the more blood out.
The autonomic nervous system regulates involuntary functions of the body, which includes the activity of the heart muscle, smooth muscles, muscles of the intestinal tract, and the glands. Autonomic nervous system has to parts the sympathetic NS which accelerates the heart rate and constricts blood vessels, thus raises blood pressure. The parasympathetic NS slows down heart rate and reduces stroke volume.
Baroreceptors are stretch receptors located in the aortic arch and in the carotid sinuses. In order for blood pressure to be maintained within
