Heart Rate Report The Circulatory system is an organ system that transports things around the body that are needed by cells. For example: Nutrients‚ such as: Oxygen‚ Food and Water. When Blood circulates around the body‚ it leaves the left ventricle of the Heart and travels to the Aorta (The largest artery in the Human body). The blood that leaves the Aorta is rich of oxygen then travels around the body in arteries‚ and to the organs. When the deoxygenated blood travels back to the lungs through
Premium Blood Heart
The cardiovascular system consists of the heart‚ blood vessels‚ and blood. This system has three main functions: Transport of nutrients‚ oxygen‚ and hormones to cells throughout the body and removal of metabolic wastes (carbon dioxide‚ nitrogenous wastes). Atria: Ventricles: In a four-chambered heart‚ such as that in humans‚ there are two ventricles that operate in a double circulatory system: the right ventricle pumps blood into the pulmonary circulation to the lungs‚ and the left ventricle pumps

through our body. The blood moves through pulmonary circulation and then continues on through systemic circulation. Pulmonary and systemic are the two circuits in the two-circuit system of higher animals with closed circulatory systems. As the heart pumps‚ blood is pushed through our body through the entire circulatory system. Oxygenated blood is pumped away from the heart to the rest of the body‚ while deoxygenated blood is pumped to the lungs where it is re-oxygenated before returning to the heart
Premium Heart Blood Artery
Structure of the heart: The heart is at the centre of the cardiovascular system. It is a hollow muscular pump that drives blood through the arteries‚ which allows it to reach the working muscles and tissues. The heart is split into two halves. The right side of the heart is separated from the left by a solid wall known as the septum. This prevents any blood on the right side coming into contact with the blood on the left side. The right side of the heart sends deoxygenated blood to the lungs in

The 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 __initiates the depolarizing

Jogging Activity and Cardiovascular Fitness Today‚ people are becoming more aware of the importance of physical activity. There has been a recent increase in the popularity of fitness activities as hobbies. However‚ despite this increasing popularity in health related activities the large majority of the American population maintains a sedentary‚ unhealthy lifestyle that had led to increased obesity and morbidity rates. According to David Chandler‚ “The largest [obesity] increase has occurred in

Research & Methods Concerning Potassium Channels in the Cardiovascular System Response to Diabetes Mellitus and Hypertension ABSTRACT Research concerning the functional role of potassium ions in the cardiovascular system with respect to hypertension and diabetes mellitus has boomed in the past decade. Through a series of experiments‚ data has been gathered which shows the diverse response of K+ channels in the cardiovascular system when exposed to these diseases. In elevated glucose levels

Biology Summer Task Our digestive systems contain glands. These glands produce enzymes. Enzymes are catalysts. Catalysts make chemical reactions happen quicker and easier. Digestive enzymes help us to break down food easier. Our bodies make lots of different digestive enzymes. Each enzyme breaks down a particular food. When an enzyme has broken down one food molecule‚ it can then break down another molecule of the same kind. It can do this over and over again. It makes the reaction happen without

The function of the cardiovascular system The Cardiovascular system circulates oxygen and nutrients to body cells and tissues. It also allows for removal of carbon dioxide and wastes from those cells and tissues. The cardiovascular system delivers hormones to targeted tissues‚ maintains body temperature‚ and helps defend the body. The cardiovascular system is made up of the heart‚ blood and blood vessels. The heart is the pump of the cardiovascular system. It consists of 4 chambers‚ which is
