Digestive System Digestive system includes the stomach‚ liver‚ pancreas‚ duodenum‚ ileum and colon. What is a Digestive system? Digestion is a breakdown and transportation of the solid and liquid food into microscopic substances therefore theses substances are then transported into different areas of the body The digestive system is a set of organs which transforms whatever we eat into substances that can be used in the body for energy‚ growth and repair. Once the food has been

Cardiovascular System Anatomy & Physiology The heart is the pump responsible for maintaining adequate circulation of oxygenated blood around the vascular network of the body. It is a four-chamber pump‚ with the right side receiving deoxygenated blood from the body at low presure and pumping it to the lungs (the pulmonary circulation) and the left side receiving oxygenated blood from the lungs and pumping it at high pressure around the body (the systemic circulation). The myocardium (cardiac muscle)

The mechanism of heart contraction and relaxation (mechanical restitution) is the basic of cardiac functioning. This mechanical restitution is driven by calcium movement and concentrations. An increase in cystolic calcium concentration causes contraction in myocardium. Calcium from the extracellular fluid enters the cardiomyocyte through the L-type Ca2+ channels after being propagated by the cardiac action potential which depolarises the cell. This flood of calcium triggers more calcium release

Excretory System Review Main Concepts: Describe the major gross anatomical structures of the excretory system. Kidneys: receive about 25% of the cardiac output; produce urine (a fluid containing water‚ ions‚ and small soluble compounds) Ureters: receive urine from the kidneys and conduct it to the urinary bladder. Urine movement involves a combo of gravity and the peristaltic contractions of smooth muscle in the walls of the ureters Urinary Bladder: receives and stores urine prior to elimination

RESPIRATORY SYSTEM A complete‚ schematic view of the human respiratory system with their parts and functions. Latin: systema respiratorium The respiratory system (or ventilatory system) is a biological system consisting of specific organs and structures used for the process of respiration in an organism. The respiratory system is involved in the intake and exchange of oxygen and carbon dioxide between an organism and the environment. The primary function of the respiratory system is to supply

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 Respiratory System is crucial to every human being. Without it‚ we would cease to live outside of the womb. Let us begin by taking a look at the structure of the respiratory system and how vital it is to life. During inhalation or exhalation air is pulled towards or away from the lungs‚ by several cavities‚ tubes‚ and openings. The organs of the respiratory system make sure that oxygen enters our bodies and carbon dioxide leaves our bodies. The respiratory tract is the path of air from the

The Muscular System The body contains 650 muscles that allow the body to move in different ways and also helps with blood flow. There are three types of muscles including: visceral‚ skeletal‚ and cardiac. Visceral muscles are the ones found in organs. This is one of the weakest of the muscle types and is also involuntary. The only voluntary muscles‚ skeletal‚ usually attach near joints. These muscles are considered voluntary because they are physical actions that can be controlled. The last muscle
