Physiology of the Circulatory System – Super Value Kit
Product Details
How are blood pressure, heart rate, and exercise related? What is the baroreceptor response? Explore the human circulatory system’s response to exercise in this very “active” student laboratory kit. Engaged students gain experience using a stethoscope and sphygmomanometer as they measure their blood pressure and heart rate while at rest, while reclining, and after exercise. They then learn how these different measurements are combined to evaluate relative cardiac fitness. Background information provides a thorough explanation of blood pressure, heart rate, and the baroreceptor response. Future health professionals will gain valuable knowledge of human physiology as well as practical experience. Kit contains enough equipment for 10 groups of students to experience the dynamic experiment at the same time. Ten stethoscopes, a sphygmomanometer, student worksheets, background information, detailed procedures, and comprehensive Teacher Notes are included.

What is the Human Circulatory System? We explain an overview of the circulatory system including its functions, how it transports oxygen and other nutrients around the body as well as the differences between systemic and circulatory elements.
The main organ of the circulatory system is the Human Heart. The other main parts of the circulatory system include the Arteries, Arterioles, Capillaries, Venules, Veins and Blood. The lungs also play a major part in the pulmonary circulation system.
The Circulatory System
The circulatory system consists of the heart and blood vessels including arteries, arterioles, veins and capillaries. Cardiac volumes, blood and blood pressure is also covered.

What is the Human Circulatory System? We explain an overview of the circulatory system including its functions, how it transports oxygen and other nutrients around the body as well as the differences between systemic and circulatory elements.
The Human Heart
The heart is a strong, powerful organ, consisting of . The heart pumps continuously, without resting and without becoming fatigued. Its function is to pump blood to the lungs and around the body. The heart is one of the key organs in the circulatory system.
The Heart Conduction System.
The conduction system of the heart refers to how the heart contracts. Here we explain how electical impluses ensure it beats regularly including specific parts of the heart involved such as the Bundle of His, Synoartial node as well as exam type questions and quizzes.
Heart Beat & Cardiac Volume
The heart beat is caused by impulses arising from two specialised groups of cells within the heart muscle. The Sino-Atrial (SA) node, situated in the wall of the right atrium initiates the beat, and the Atrioventricular (AV) node which is positioned between the ventricles and continues to distribute the wave of impulses.
Veins
Veins are blood vessels which carry deoxygenated (or very low levels of oxygen) blood back to the heart. The exception to this rule is the pulmonary vein, which carries oxygenated blood, from the lungs, back to the heart, ready to be pumped around the rest of the body.
Capillaries
Capillaries are the smallest of all blood vessels and form the connection between and s arteries branch and divide into arterioles and continue to reduce in size as they reach the muscle they become capillaries. Here the capillaries form a capillary bed, which is a vast expanse of very small vessels forming a network throughout the muscle.
Arteries
Arteries are blood vessels which carry blood away from the heart. All of which, with the exception of the pulmonary artery, carry oxygenated blood. The most widely known artery within the human body is the Aorta.
Blood Composition & Function
Blood has many functions including transportation of nutrients round the body, maintaining homeostasis and the imune system. It is made up of plasma, red blood cells, white blood cells and platelets.
Blood Pressure
The rate and distribution of blood flow through the is variable and related to several factors including physical activity, cardiac output (the amount of blood pumped out of the heart) and venus return or the blood returning to the heart through the veins.
