THE CARDIOVASCULAR SYSTEM
Blood vessels
Veins
Capillaries
Arteries
Blood
Plasma
55% of blood
About 90% water
Nutrients
Specialized molecules
Hormones
Antibodies
Waste
Isolated by centrifuge
Red blood cells (erythrocytes)
Carry oxygen and carbon dioxide
Hemoglobin
Small and biconcave
No mitochondria or nucleus
Average lifespan of 120 days
Broken down in the liver and spleen
Produced in the bone marrow
Controlled by erythropoietin
Kidneys
Platelets (thrombocytes)
Attracted to wound sites
Convert fibrinogen into fibrin
Sticky plug
White blood cells (leukocytes)
Neutralize bacteria and viruses
Larger than red blood cells
Have nuclei and mitochondria
Heart
Behind the breastbone and between the lungs
Divided into
Left heart
By the septum
Right heart
Upper chambers: Atria
Receive blood
Right atrium
Receives blood lacking oxygen
Inferior and superior vena cava
Tricuspid valve
Right ventricle
Pulmonary valve
Pulmonary artery
Lungs
3 more items...
Lower chambers: ventricles
Pump out blood
3 layers
Myocardium
Endocardium
Pericardium
Cardiac cycle
Beginning
Aortic or pulmonary valve closes
Diastole
Ventricles fill
Systole
