PPT-Malfunctions and disorders of the heart and blood vessels

Hypertension High Blood Pressure caused by a narrowing of the arterioles resulting in an increased resistance to the flow of bloodincreases the strain on the heart Causes implicated . Also its possible for otherwise healthy people to develop severe illness so any one concerned about their illness should consult their doctor There are emergency warning signs that should signal anyone to seek medical care urgently Emergency Warning 11.3 (. pg. 367 – 269). Malfunctions. Abnormal functioning of the immune system. Two types of problems:. Immunodeficiency diseases. Inappropriate attacks of the immune system against non-threatening agents.. SEMESTER TWO. COURSE:ANATOMY AND PHYSIOLOGY 2. CHAPTER NINE:CARDIOVASCULAR SYSTEM. LECTURER: MAHAD ALI WARSAME. 2014. Key terms. cardiovascular system. : . a collection of organs that transport blood throughout the body (consists of heart and blood vessels). Function. Blood Vessels. Types of Blood Vessels. Arteries. :. Carry blood away from the heart. Blood leaving heart starts off in large vessels called . arteries. Arteries become smaller in diameter as they branch out to spread through the body. Learning objectives. To understand the functions of the circulatory system.. To be able to identify the differences between veins, arteries and capillaries. . To be able to identify and label the components of the heart.. 2 circuits: pulmonary and systemic.. The Transport System. Carries deoxygenated blood from the right side of the heart to the lungs and back to the left side.. Pulmonary Circuit. Left side of the heart pumps oxygenated blood throughout the body’s organs.. Blood Vessels P A R T A Blood vessels and circulation Blood is carried in a closed system of vessels that begins and ends at the heart 5 types of blood vessels Arteries – carries blood away from the heart Delivery system of dynamic structures that begins and ends at the heart. Arteries: carry blood away from the heart; oxygenated except for pulmonary circulation and umbilical vessels of a fetus. Capillaries: contact tissue cells and directly serve cellular needs.
