Cardiovascular system

The Medical Renaissance: The Cardiovascular System Medical care today is something whose history and presence we take for granted. It is sterile, highly regulated, and only exercised by trained, experienced professionals. However, before and during the Middle Ages, medical care was almost nonexistent—due in large part to our lack of knowledge, or lack of correct knowledge, of how the human body functioned. Almost all of our understandings of the human body had been from Galen in Ancient…

runs a race and finishes first. That individual is breathing harshly and if one could see internally, the heart is pumping blood rapidly as well. This is known as the Cardiovascular System. It contains not only the heart, but also the blood vessels, blood and much more which will be further explained in greater detail. The venous system takes blood back to the heart. It flows from the capillaries to the veins. The biggest vein in the body is the inferior vena cava. The superior cava carries…

Blood pressure is defined as a measurement of the force with which blood presses against the wall of a blood vessel. Blood pressure, as popularly used, is the pressure determined indirectly, existing in the large arteries at the height of the pulse wave. When a blood pressure reading is taken, the systolic over diastolic value is determined. Systolic pressure is defined as an aspect of a blood pressure reading which indicates the maximum arterial pressure occurring during contraction of the left…

What is the cardiovascular system? The cardiovascular system functions when it transports oxygen from the lungs to the tissues around the body. While also transporting oxygen around the body this system transports carbon dioxide which is a waste product from the body to the lungs. The cardiovascular system works when a person breathes air through their mouth and nose and then it travels the lungs. Oxygen from the air is slowly absorbed into the bloodstream through the lungs. The heart then…

extremely life threatening. It typically happens on the left side and less likely on the right, can happen on both sides at same time, if this happens it normally starts with left and moves to right. The causes of this condition are from other cardiovascular problems, such as, hypertension, coronary artery disease, and various valve conditions. Non-heart related conditions can cause CHF as well. In early stages might not notice any changes in health but as it gets worse you notice your body…

The Affects of Light Exercise on the Cardiovascular System Maggie Moreau 23T Abstract The objective of this lab report and our experiment was to show how the cardiovascular system is affected by reclining or standing position and light exercise. The average reclining systolic pressure is 116.2 mmHg, and the average standing systolic pressure is 115.9 mmHg. The standard deviation for reclining systolic pressure was 8.2, and the standard deviation for standing systolic pressure is 12.3.…

where you live, stress is something that always plays a part. And it can affect a lot of aspects in life. But do people realize it affects their bodys? Stress can disturb the cardiovascular and reproductive system, and mental health. The heart and blood vessels are the two main elements that make up the cardiovascular system. These two elements supply our organs with nourishment and oxygen. When…

Cardiovascular system is an organ system that helps in the circulation of blood and transportation of nutrients, oxygen, carbon dioxide and hormones to and from the cells in the body to provide nourishment and prevent diseases, stabilize temperature and pH and maintain homeostasis. It consists of the heart and the blood vessels. This assignment contains different aspects of the same. The first question is about the various differences between the cardiovascular system of a normal adult and older…

The Cardiovascular System: An Overview of Blood, Vessels, and Heart – Healthy to Diseased The cardiovascular system, also known as the circulatory system, consists of the heart, blood, and blood vessels (Mertz, 2004). The cardiovascular system moves oxygenated blood and nutrients through to and removes carbon dioxide and wastes out of the body’s cells. (Miracle of the Human Body, 2010) I will provide an overview how a healthy cardiovascular system does this by first discussing the anatomy of it,…

1. What does the PR interval on the ECG represent? What is the normal value? The P-R interval is the interval between the beginning of electrical excitation of the atria and the beginning of excitation of the ventricles and its normal value is 0.12- 0.20 seconds. 2. What does the QRS complex on the ECG represent? What is implicit in the information that the QRS complexes on Mr. Ortega’s ECG had a normal configuration? The QRS complex is the most important in the EKG since its represents…
