1. To consolidate knowledge about the structure and functions of blood. 2. Show the movement of blood and lymph. 3. Consider the structural features of the circulatory organs. Educational portal My University - www.moi-univtrsitet.ru Faculty of Education Reform - www.edu-reforma.ru

1. The structure of the circulatory system. 2. Vessels, their types. 3. The structure of blood vessels. 4. The structure of the heart. 5. Circles of blood circulation. Educational portal My University - www.moi-univtrsitet.ru Faculty of Education Reform - www.edu-reforma.ru

Aorta - Arteries - Veins - Capillaries - Arterial blood - Venous blood - 5 slide aorta veins arteries Educational portal My University - www.moi-univtrsitet.ru Faculty of Education Reform - www.edu-reforma.ru

The aorta is a large artery. Arteries are the vessels that carry blood from the heart. Veins are the vessels that carry blood to the heart. Capillaries are the smallest blood vessels. Arterial blood is blood saturated with oxygen. Venous blood is blood saturated with carbon dioxide. 6 slide Educational portal My University - www.moi-univtrsitet.ru Faculty of Education Reform - www.edu-reforma.ru

14 slide Gas exchange in capillaries Capillaries form an extensive network of vessels that permeate all parts of the body. The diameter of the capillaries is 7-10 microns, and their walls, consisting of only one endothelium, are permeable to water and substances dissolved in it. It is in the capillaries that the exchange of substances between blood and body cells takes place.

On the subject: methodological developments, presentations and notes

Test work in biology, grade 8, program I. N. Panomareva. Topic: "Blood. Blood circulation". Form: test tasks of various types ...

The lesson is aimed at the formation of not only theoretical knowledge, but also the development of practical skills and abilities. The chosen topic has perspectives in terms of healthy lifestyle education. The lesson forms positive ...

"Human blood circulation" - Right atrium. Highlight factors that have a negative effect on the cardiovascular system. Competencies. Vessels. Circulatory system. Transport of blood with nutrients. * The diagram shows Mosso's experiment. C) The human heart is four-chambered. author - A.V. Klinov Pirogov N.I. 1810-1881.

"Blood pressure" - Blood pressure. Blood pressure is one of the most important parameters characterizing the work of the circulatory system. Presentation by Polina Shikhareva 8G. Blood pressure. Similarly, the pressure in the large veins and in the right atrium differs slightly. Blood pressure measurement procedure.

“Blood circulatory system” - Fish class. Biology teacher Katenina Tatyana Nikolaevna. A type of shellfish. Ringed worms. The circulatory system is closed. Circulatory system. Lancelet circulatory system closed, heart is absent. The blood is partially mixed in the ventricle. Brontsevskaya secondary school. Arterial and venous blood do not mix.

"Blood circulation in humans" - Left atrium Right atrium. The structure of the heart. Small circle of blood circulation. 2. Contraction of the ventricles, relaxation of the atria 0.3 sec. A heart. The entire cardiac cycle takes 0.8 seconds. Blood movement. Blood pressure changes in different phases cardiac cycle. Circulatory organs. begins in the right ventricle. Ends in the left atrium.

"Lipids" - Composition of lipids and lipids. Pupkova V.I. Lipids: lc, xc, tg lipoproteins - a complex of lipids with apoproteins: - chylomicrons - tg - lponp - tg - lpnp - 70% xc - lpvp - 20-30% xc. Diagnostically significant serum lipid levels: a modern perspective. HYPERLIPOPROTEINEMIA - the main factor cHD riskcharacterized by increased content lipids and LP in blood serum.

Slide 5

The cardiovascular system

5 The cardiovascular system includes the heart, as well as the bodily and pulmonary circulation, which consists of a network of veins and arteries necessary to support the circulation of blood that is essential to life Like a motor, the heart pumps blood to all organs and tissues of the body. Blood carries oxygen nutrients and other vital components, and at the same time collects and removes decay products and carbon dioxide.

• - a closed vascular pathway, providing a continuous blood flow, carrying oxygen and nutrition to cells, carrying away carbon dioxide and metabolic products.

• Artery structure
• Comes from the heart
• Outer layer - connective tissue
• The middle layer is a thick layer of smooth muscle tissue
• Inner layer - a thin layer of epithelial tissue

• Vein structure
• Carries blood to the heart
• Outer layer - connective tissue
• Middle layer - a thin layer of smooth muscle tissue
• Inner layer - unilamellar epithelium
• Have pocket valves

• Capillary structure
• Carry blood to and from organs and tissues
• The thinnest vessels
• Unilamellar epithelium

• The heart works automatically;
• Regulates the central nervous system - the parasympathetic (vagus) nerve - slows down; sympathetic nerve - enhances work
• Hormones - adrenaline - enhances, and norepinephrine - slows down;
• Ions K + slows down the work of the heart;
• Ion Ca + enhances its work.
