Summary Introduction
To write:
The medical importance of the anatomoses in the coronary arterial system.
Introduction:
The heart is the central organ of the circulatory system. It consists of four chambers: two upper chambers or atria and two lower chambers or ventricles. Blood passes across a valve before parting each heart chamber.

This is Anatomy and Physiology II related questions. More specifically on blood vessels. Please help me answer these questions, thank you :)
List all the blood vessels a blood cell from the left fibula vein would have to go through to arrive in the right ulnar artery. There is no left brachiocephalic artery. How does the anatomy of the left side of the body differ from the right in this region? What type of tissue creates a valve? A piece of the great saphenous vein is removed from the leg and used to bypass clots that form in the arteries that supply the heart muscle. Why doesn't the leg suffer from the removal of a piece of this vein?
ANSWER THIS QUESTION BY RELATING IT TO THE PHOTOSKIP THIS IF YOU ALREADY ANSWERED OTHERWISE DOWNVOTE.Explain how the following factors affect the blood velocity and volume flow rate as well as potential risks for stroke: i. the pulsatile nature of blood flow, ii. elasticity of the wall of the blood vessels, and iii. gradual narrowing and curvature of blood vessels.

- 1. Mr. Garcia had a myocardial infarction. Explain what happened to his heart muscle and vascular system. What is a STEMII? 2. Mr. Garcia's chest pain resolved after two sublingual NTF at 3-minute intervals and 2 mg of IV morphine. In the cardiac catheterization lab he was "found to have a totally occluded distal right coronary artery and a 70% occlusion in the left circumflex coronary artery. The left anterior descending artery was patent. Angioplasty of the distal right coronary artery resulted in a patent infarct- related artery with near normal flow. A stent was left in place to stabilize the patient and limit infarct size. Left ventricular ejection fraction was normal at 42%, and a posterobasilar scar was present with hypokinesis." a. Explain angioplasty and stent placement. Define occluded occlusion. b. What is the purpose of this medical procedure?arrow_forward11. You instructed properly the patient for venipuncture.
