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

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

The digestive‚ respiratory and the cardiovascular system are all interrelated in order to make the human body work effectively and efficiently by working as an orchestra. The cardiovascular system and the respiratory will work together in order to perform the gas exchange which is passing of oxygen from the alveoli into the blood flow and then the carbon dioxide passes trough the blood flow and is breathed out from the body. This means oxygen (in) CO2 (out).

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
Premium Heart Blood Circulatory system
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

The cardiovascular system The cardiovascular system is a system that is able to transport things such as nutrients through the body in order for them to reach their destinations. The cardiovascular system is made up of our hearts‚ our blood vessels‚ arteries‚ veins and capillaries and our blood. The system is also linked to the respiratory system. The heart The heart is the size of a closed fist‚ this can be located in the thoracic cavity. The thoracic cavity is a chamber of the body that is between

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

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

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
