Cardiovascular and Lymphatic systems Flashcards
Function of the cardiovascular system
- Transporting nutrients
- Oxygenize the body by transporting oxygen by the cells in the blood
- Removing waste products from blood (ex. CO2)
3 Types of valves for the heart
- Tricuspid Valve: located between the right atrium and right ventricle
- Bicuspid Valve: located between the left atrium and left ventricle
- Semilunar Valve: located between the right ventricle and pulmonary artery, and the left ventricle and aorta
3 layers of the Heart
- Pericardium: 2 layer sac covering the heart that holds pericardial fluid, allowing layers to move without friction. Has visceral layer closest to myocardium and parietal layer lining pericardium
- Myocardium: Middle, thick, muscular layer of the heart
- Endocardium: Inner lining of the heart
Aorta
largest artery in the body, originating from left ventricle descending down into the thorax and abdomen
Arteries
Blood vessels that carry blood away from the heart, smallest arteries called arterioles
Veins
Blood vessels that carry blood back to the heart, smallest veins called venules
Capillaries
Microscopic blood vessels that connect arterioles with venules
Erythrocytes
Red blood cells (RBC) that carry oxygen
Leukocytes
White blood cells (WBC) that combat the infection and respond to the inflammation
Platelets
Element in the blood that helps with clotting. Platelets are also called thrombocytes
Lymphatic System
Removing excess fluid in tissues that accumulate because of metabolic activity
What the Lymphatic system consists of
Lymph nodes: filter to keep bacteria out of blood
Spleen: Largest lymphatic organ
Thymus Gland: Primary lymphatic organ that helps develop immune system
Lymph: Colourless fluid
