List and briefly explain the 3 factors that affect SV: preload, contractility and afterload. Explain the significance of safranin in Gram staining. Why is the flat portion of the oxyhemoglobin dissociation curve clinically significant? Describe the importance of the EJC complexes for the ...
What factors influence how well oxygen and carbon dioxide are exchanged at the respiratory membrane? What is the role of cholesterol for the steroid hormones? List three factors that affect resistance. Define the terms contractility, preload, and afterload, and explain how these factors affect cardia...
Before congenital heart surgery is undertaken, the assessment of left ventricular contractility, preload, and afterload is important for preoperative planning to obtain satisfactory clinical outcomes. Afterload is left ventricular wall stress during systole. Wall stress results from the interaction of pressur...
Lymphatic smooth muscle cells have characteristics of both smooth muscle and cardiac muscle cells which demonstrate spontaneous contractions and contractile forces that are modulated by preload, afterload, and contractility. In concert with uni-directional valves, intrinsic lymphatic pumping (rate and ...
What can be learned about “cookie”？It collects information on you usually without your knowing it.
the factors causing an increase in contractility in the heart work by causing an increase in intracellular calcium ions during contraction. Under one existing model, the five factors of contractile myocardium performance are considered to be heart rate, conduction velocity, preload, afterload, co...
The heart is a muscular organ located on the left side of the human chest. It is comprised of four chambers which are separated from each other by valves.Answer and Explanation: The heart pumps blood throughout the body. The muscles of the heart contract rhythmically and these contractions ...
① Venous dilation causes blood to remain in the periphery, reducing blood volume, preload, and ventricular wall tension; it dilates arteries, reduces peripheral vascular resistance, and increases systolic arterial pressure and mean arterial pressure (afterload). ) decreases, reducing myocardial oxygen ...
What is the difference between preload, diastolic, afterload, and systolic? What is considered mild pulmonary hypertension? How does psychological stress cause hypertension? Does pulmonary hypertension cause low blood pressure? A) When you measure systemic arterial blood pressure, what are you actually ...
