Quiz 9
Leukemia
Type of cancer that involves the overproduction of leucocytes
"lub-dub"
Sounds of blood against closed valves "Lub" - AV valve "Dub" - Semilunar valve
Artery
Carry blood away from the heart Most arteries carry oxygenated blood
Vein
Carry blood towards the heart Most veins carry deoxygenated blood
Sickle-cell anemia
Abnormal "sickle-shaped" hemoglobin
When the antigen and antibody bind, they clump together in what is called a
Agglutination reaction
A
Antigen - A Antibody - B Can donate to A, AB Can receive A, O
O
Antigen - AB No antibody Can donate to A, B, AB, O Can receive O

Atherosclerosis
Involves the buildup of plaque which impairs blood flow
Blood circulation
Pulmonary circulation Deoxygenated blood from body to superior/inferior vena cava to right atrium to right ventricle to pulmonary trunk to pulmonary arteries to left and right lungs Systemic circulation Oxygenated blood from lungs to pulmonary veins to left atrium to left ventricle to ascending/descending aorta to body
Formed elements of blood
Erythrocytes Platelets Leukocytes --> Granulocytes and argranulocytes
Cardiac output
stroke volume x pulse rate
Heart murmur
A heart murmur is a swishing sound heard when there is turbulent or abnormal blood flow across the heart valve
Fetal versus adult circulatory systems
Exchange of gases takes place in the placenta, not the lungs Fetal pigs have ductus arteriosus and foramen ovale
Spleen
Filters blood
Thoracic region
Heart R. and L. atria R. and L. ventricles Veins (blue latex) Cranial (superior) vena cava Caudal (inferior) vena cava Arteries (pink latex) Aortic arch/aorta Pulmonary artery (trunk) Ductus arteriosus
Umbilical arteries
The umbilical arteries carry the non-oxygenated blood away from the heart to the placenta for oxygenation
Do all veins carry deoxygenated blood? Do all arteries carry oxygenated blood?
Unlike other arteries, the pulmonary artery carries deoxygenated blood. Once the veins have brought this blood from the body to the heart, it is pumped to the lungs. The pulmonary vein moves the oxygenated blood from the lungs back to the heart.
Abdominal cavity
Veins (blue latex) Caudal vena cava Umbilical vein Arteries (pink latex) Abdominal aorta Umbilical arteries
Neck region
Veins (blue latex) External jugular Internal jugular vein Arteries (pink latex) Common carotid
