Figure 40.10 Which of the following statements about the circulatory system is false?
- Blood in the pulmonary vein is deoxygenated.
Introduction:
The complex circulatory system has divided into three divisions the systemic circuit, the pulmonary circuit, and the coronary circuit. In coronary circulation, the heart receives blood directly from the aorta derive from the heart while in the pulmonary and systemic circulation, the heart propels blood to the lungs or remaining part of the body.
Answer to Problem 1VCQ
Correct answer:
The correct answer is option (c) Blood in the pulmonary artery is deoxygenated.
Explanation of Solution
Explanation/justification for the correct answer:
Option (c) blood in the pulmonary artery is deoxygenated. Arteries typically carry oxygenated blood, except pulmonary arteries that taken up deoxygenated blood from the right ventricles, and then carried to the lungs for oxygenation. So, the correct answer is option (c).
Explanation for the incorrect answer:
Option (a) blood in the pulmonary vein is deoxygenated. The pulmonary veins carry the oxygenated blood from the lungs to the left atrium of the heart. So, this is an incorrect option.
Option (b) blood in the inferior vena cava is deoxygenated. Superior vena cava takes up deoxygenated blood from the brain and arms while inferior vena cava carries blood from the lower organs and legs to the right atrium. So, this is an incorrect answer.
Option (d) blood in the aorta is oxygenated. The blood gets pumped into the left ventricle through the bicuspid valve or mitral valve and then passes to the aorta, which further circulates oxygenated blood to the organs and muscles of the body. So, this is an incorrect answer.
The statement blood in the pulmonary artery is deoxygenated is false. Hence, the correct answer is option (c) blood in the pulmonary artery is deoxygenated.

- Which statement concerning the pulmonary vein is correct? It carries oxygenated blood from the lung to the left ventricle of the heart It carries deoxygenated blood from the right ventricle of the heart to the lung It carries deoxygenated blood from the right atrium of the heart to the lung It carries oxygenated blood from the lung to the left atrium of the heart None of the abovearrow_forwardWhich of the following is NOT a part of all circulatory systems? 1.something to cause force/pressure 2.vessels 3.a fluid that moves throughout the body 4.bloodarrow_forwardTrue or false Blood pressure is a product of cardiac output and resistance. Blood pressure is lowest in the vena cava The pulse is felt at the large veins Arterioles are the most important vessels in regulation blood pressure. Veins and lymph vessels have valves Only arteries have smooth muscles Veins always carry deoxygenated blood.arrow_forward
- Which row does not correctly contract the pulmonary circulation and the systemic circulation? The statement above is best completed by the answers in row: Row Pulmonary circulation Systemic circulation has a limited number of blood vessels has a large number of blood vessels goes between the right ventricle and the left atrium goes between the left ventricle and the right atrium veins carry oxygen-poor blood veins carry oxygen-rich blood carries blood to and from the body tissues carries blood to and from the lungsarrow_forwardWhich of the following statements about the circulatory system is INCORRECT? Question 25 options: With respect to diameter: Aorta > arteries > arterioles > capillaries Arterial walls are thicker than the walls of veins of the same size Arteries retain their round shape when empty, veins are thin and tend to collapse Veins always carry de-oxygenated blood away from capillary beds Blood pressure in veins is lower than in arteries of the same sizearrow_forwardWhich of the following is NOT true of gas, nutrient, and fluid exchange between capillaries and body tissues? Blood pressure is higher entering than leaving the capillary Osmotic pressure is constant across the capillary Blood pressure is less in the capillary than in the tissuesExcess fluid from the exchange enters the lymphatic duct Blood enters the capillary from the arteriolearrow_forward
- Which one of the following statements is incorrect? There are no valves in arteries. the walls of veins are thin. the walls of capillaries are thick. veins carry blood into the heart.arrow_forwardWhat causes the atrial filling of blood? high pressure in the atria low pressure in the ventricle Low pressure in the atriaarrow_forwardHow do arteries differ from veins? Arteries have thicker smooth muscle layers to accommodate the changes in pressure from the heart. Arteries carry blood. Arteries have thinner smooth muscle layers and valves and move blood by the action of skeletal muscle. Arteries are thin walled and are used for gas exchange. Arteries have direct connections to capillaries whereas veins do not.arrow_forward
- There is a semilunar valve between the_____ and _____ right ventricle and the aorta. left ventricle and the aorta left atrium and the pulmonary trunk. right atrium and the right ventricle. left ventricle and the pulmonary trunk. blood group is AB negative. He can therefore donate blood to people who are: A negative and B negative AB positive and AB negative A negative; A positive;AB negative and AB positive all blood groupsarrow_forwardWhich of the following structures in the circulatory system carries oxygenated blood? a pulmonary artery b right ventricle c superior vena cava d aortaarrow_forwardWhich of the following is the correct sequence of blood flow through pulmonary circulation? 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 atriumarrow_forward
