Cardiovascular System: Intrinsic Conduction System 1. The intrinsic conduction system consists of __autorhythmic____ __cardiac__ cells that initiate and distribute __impulses_____ throughout the heart. 2. The intrinsic conduction system coordinates heart activity by determining the direction and speed of ____heart depolarization____. This leads to a coordinated heart contraction. 3. List the functions for the following parts of the intrinsic conduction system: a. SA node _sets the pace for the

Cardiovascular System: Blood Laszlo Vass‚ Ed.D. Version 42-0007-00-01 Purpose Explain why you did this lab and what if any safety precautions needed to be followed. For this lab I had to prick my finger‚ then with the bleach solution I had to dab it and then carefully drop the blood on the slide. Once I was finished I had to take the second slide and smear the blood. I had to let the slide dry. Then I had to prick my finger again and make 3 more slides. Then I had to mix the chemical

Chapter 19 The Cardiovascular System: The Heart 1. How is the heart positioned in the mediastinum? It rests on the diaphragm‚ near the midline of the thoracic cavity‚ with about two-thirds of the mass lying to the left of the body’s midline. 2. Which layer of the pericardium is both a part of the pericardium and a part of the heart wall? Serous pericardium 3. What is the function of pericardial fluid? Reduces friction between the membranes as the heart moves 4. From most superficial

Human Body May 30‚ 2010 The Cardiovascular and Muscular Systems Organ system is a group of organs that work together to perform a certain task. Humans have a variety of systems due to the complexity of the species’ organism. The human body consists of biological systems‚ that consist of organs‚ that consist of tissues‚ that consist of cells and connective tissue. Although an organ has a specific function‚ organs also function as part of a group. The organ system is the organizational unit

Without the cardiovascular system‚ we would not be alive. The cardiovascular system is essentially a synonym for the circulatory system which is "the system that circulates blood and lymph through the body‚ consisting of the heart‚ blood vessels‚ blood‚ lymph‚ and lymphatic vessels and glands" (Circulatory…). The cardiovascular system is crucial to have‚ as it supplies oxygen and gives nutrients to every part of our body. The cardiovascular system‚ in fact‚ is one of the most important systems consisting

Homeostasis is defined as the adjustments a body makes to maintain an environment conducive to life. All of the organ systems in the human body must maintain a steady internal environment for the body to function properly. The factors that need to be controlled are water and salt content‚ PH balance‚ oxygen‚ sugar‚ protein‚ body temperature‚ and blood and glucose concentration. The basic principle of homeostasis is when there is an abnormal internal condition‚ it will be detected and a variation

The cardiovascular system‚ also known as the circulatory system‚ is composed of the heart‚ blood vessels‚ and blood. The term cardiovascular refers to the heart (cardio-) and blood vessels (vascular). The term circulatory refers to the circulation of the blood. The heart is a muscular pump and its regular contractions send blood into tough‚ elastic tubes called arteries‚ which branch into smaller vessels and convey oxygen-rich blood through the body. The arteries eventually divide into tiny capillaries

Introduction: The cardiovascular system has multiple components that work to ensure an enough oxygen is supplied to the muscles‚ both at rest and during exercise. The objective of this laboratory session was to measure‚ and compare how the cardiovascular system responds to dynamic and isometric exercise. The research question for this lab was “What is the effect of different exercise modalities on the cardiovascular system?”. In response to this research question‚ the following hypothesis was formed

The cardiovascular system is the movement of blood being permitted around the body to vital organs and muscles with the components of the heart‚ blood‚ and blood vessels combining together to make the cardiovascular system work. The cardiovascular systems is vital in the human body as it promotes the body’s delivery system for blood being pumped around the entire body for survival. The respiratory system also has importance in the body as it is the system to transport air into the lungs to aid the
