Visit this site (http://openstaxcollege.org/l/heartvalve) to observe an echocardiogram of actual heart valves opening and closing. Although much of the heart has been removed from this gif loop so the chordae tendineae are not visible, why is their presence more critical for the atrioventricular valves (tricuspid and mitral) than the semilunar (aortic and pulmonary) valves?
In the systemic circuit, the hearts _______ half pumps blood to all body regions; then blood flows to the heart. a. left; deoxygenated; oxygenated b. right; deoxygenated; oxygenated c. left; oxygenated; deoxygenated d. right; oxygenated; deoxygenated
Contraction of _______ drives the flow of blood through the aorta and pulmonary arteries. a. atria b. veins c. arterioles d. Ventricles
How do arteries differ from veins? a. Arteries have thicker wall layers to accommodate the changes in pressure from the baa b. Arteries carry blood. c. Arteries have thinner wall layers and valves and move blood by the action of skeletal muscla d. Arteries are thin wafted and are used for gas exchange.
The heartbeat includes: a. the systole when the heart relaxes and fills. b. the diastole when the heart contracts and empties. c. pressure that causes the AV valves to open, filling the ventricles. d. rising pressure in the ventricles to open the AV valves and close the SL valves. e. the lub sound when the SL valves open and the dub sound when the AV valves close.
Figure 40.10 Which of the following statements about the circulatory system is false? Blood in the pulmonary vein is deoxygenated. Blood in the inferior vena cava is deoxygenated. Blood in the pulmonary artery is deoxygenated. Blood in the aorta is oxygenated.
Match the terms with their descriptions. ____capillary a. filters out pathogens ____lymph node b. cardiac pacemaker ____atrium c. blood vessel with valves ____ventricle d. largest artery ____SA node e. receives blood from veins ____vein f. exchange site ____aorta g. receives blood from atrium
