Group of answer choices Right atrium → right ventricle → pulmonary arteries → pulmonary capillaries (in lungs) → pulmonary veins → left atrium Left atrium → left ventricle → pulmonary arteries → pulmonary capillaries (in lungs) → pulmonary veins → right atrium Right atrium → right ventricle → pulmonary capillaries (in lungs) → pulmonary arteries → pulmonary veins → left atrium Left atrium → left ventricle → pulmonary capillaries (in lungs) → pulmonary arteries → pulmonary veins → right atrium Left atrium → left ventricle → pulmonary veins → pulmonary arteries → pulmonary capillaries (in lungs) → right atrium
- note whether the statements below are consistent with an open or closed circulatory system. The circulating fluid flows in one direction (unidirectionally) through a circulatory loop. The circulating fluid is called hemolymph. Ostia are pores in the heart, important for circulatory function. The circulating fluid is called blood. The circulating fluid remains in vessels as it moves throughout the organism. Is the more efficient type of circulatory system.Fill in the table to compare and contrast the structures of the heart and the path of circulation for each organism in the activity.

Select all correct statements. Check All That Apply Blood vessels include arteries, capillaries, and veins. Blood vessels include arteries, capillaries, and veins. Arteries have more smooth muscle than veins. Arteries have more smooth muscle than veins. Veins have slower blood velocity than capillaries. Veins have slower blood velocity than capillaries. Capillaries exchange dissolved substances with interstitial fluids. Capillaries exchange dissolved substances with interstitial fluids. The heart pumps interstitial fluids.
- How can you tell which side of the heart is the ventral surface (the surface closer to your chest)? How many chambers are found in the mammalian heart? List these chambers. Which chambers are the pumping chambers of the heart? Which chambers are the receiving chambers of the heart? How do the walls of the atria compare with the walls of the ventricles and why are they different? Which heart chamber has the thickest muscle wall? Why is it necessary for the chamber in the above question to have a thicker muscle wall? What is the purpose of heart valves? Name & compare the heart valves found between the upper & lower chambers of the right and left sides of the heart.In which animal does blood flow through a pulmocutaneous circulatory circuit before circulating through the rest of the body? insect fish frog annelid molluscBriefly describe the differences among animal circulatory systems. What is an open system versus a closed? What are the anatomical differences among vertebrate hearts?
- Arrange the correct pathway of the blood systemic artery>>veins>>right side of the heart>> lungs>> left side of the heart >> systemic artery systemic artery>>left side of the heart>> lungs>> right side of the heart >> systemic vein >> artery systemic vein>>artery>>left side of the heart>> lungs>> right side of the heart >> systemic vein systemic vein>>artery>>right side of the heart>> lungs>> left side of the heart >> systemic veinIf you added "Pulmonary circulation" and "Systemic circulation" to the concept map, what new connecting phrases might you write? Select all that apply. Check All That Apply The circulatory system is divided into two loops called pulmonary circulation and systemic circulation. In pulmonary circulation, blood is pumped to the lungs and back to the heart. In systemic circulation, blood is pumped only to the lower body and back to the heart. The heart pumps oxygenated blood to the body tissues in pulmonary circulationhttps://www.hhmi.org/biointeractive/vertebrate-circulatorium Compare and Contrast: Adult to fetal heart in mammals Fetal heart in mammals to diving heart in crocodile. To see the differences in the mammal heart as a fetus vs adult. Go to "Mammal". Click on "Heart Detail". Click "Activate".
