A mini slide show on blood and bl


  • 1. A blood vessel is a tubular structurecarrying blood through tissues and organs There are three varieties of bloodvessels: arteries, veins, and capillaries Blood vessels provide two important meansof measuring vital health statistics: pulseand blood pressure

2. Arteries - carries blood away fromheart Capillaries - connects arteries toveins. Veins- carry blood back to the heart. 3. Largest Artery in the body Connected to left ventricle Distributes Oxygenated Blood from the left ventricleof the heart to every organ. Ends in abdomen after bifurcation (to divide or forkinto two branches) of the abdominal aorta in the twocommon iliac arteries. Iliac arteries are several anatomical structures locatedin the pelvis (base of the spine to the rear limbs) 4. Returns Deoxygenated Blood to the heart Cranial Vena Cava - above the heart, formsfrom convergence of the left andright brachiocephalic veins Caudal Vena Cava - travels up alongsidethe abdominal aorta with blood from thelower part of the body 5. Carries Deoxygenated Blood from the heart to the LUNGS~ One of the only arteries that carry deoxygenated blood The main Pulmonary artery begins at: base of the RIGHTVENTRICLE Branches out into 2 pulmonary arteries, left and right, whichcarry deoxygenated blood to the lungs. 6. The bodily fluid that transports oxygen, digestedfood, etc. throughout the body Contains:dissipated proteinsglucosemineral ionshormonesCO2plasma 7. Red Blood CellsCarried in Plasma White Blood Cells Platelets 8. Red blood cells (erythrocytes): shaped slightly indented,flattened disks. RBCs contain: iron-rich protein hemoglobin. Blood gets itsbright red color when hemoglobin picks up oxygen in the lungs. As the blood travels through the body, the hemoglobin releasesoxygen to the tissues. 9. White blood cells (leukocytes): key part defending the bodyagainst infection. Less WBCs produced than RBCs, but production may beincreased. Granulocytes and lymphocytes (types of WBCs) travel along thewalls of blood vessels, fighting germs and may attempt todestroy cells that have become infected or have changed intocancer cells. After the body has been challenged by infections, lymphocytes"remember" how to make the specific antibodies to counter thevirus should it enter the body again. 10. Platelets (thrombocytes): tiny oval-shaped cells Made in: bone marrowHelps in clotting blood.When a blood vessel breaks, platelets gather in thearea and help seal off the leak. Platelets and clotting factors (Proteins that helpwith clotting) work together to form solid lumps,sealing wounds and cuts to prevent bleeding frominjured areas. 11.
