Of the following, which does not explain why the partial pressure of oxygen is lower in the lung than in the external air? Air in the lung is humidified; therefore, water vapor pressure alters the pressure Carbon dioxide mixes with oxygen Oxygen is moved into the blood and is headed to the tissues Lungs exert a pressure on the air to reduce the oxygen pressure.
A developing fetus gets oxygen from its mothers blood. Fetal capillaries run through pools of maternal blood in an organ called the placenta. As fetal blood runs through these capillaries, it exchanges substances with the maternal blood around the capillary. The hemoglobin made by a fetus is different than that made after birth. Fetal hemoglobin binds oxygen more strongly at low oxygen levels than normal hemoglobin. How would fetal hemoglobins somewhat higher affinity for oxygen benefit the fetus?
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.
What term best describes the exchange of oxygen and carbon dioxide at the interface between the systemic capillaries and the peripheral tissues? Cellular respiration External respiration Internal respiration Ventilation
Which of the following statements best describes the function of the pulmonary arteries or veins? Pulmonary arteries carry deoxygenated blood from the right ventricle of the heart to the lungs. Pulmonary arteries carry deoxygenated blood to the right atrium of the heart from the lungs. Pulmonary veins carry deoxygenated blood from the lungs to the left atrium of the heart. Pulmonary veins carry oxygenated blood from the lungs to the right atrium of the heart.
Which of the following is incorrect about pulmonary circulation? A. Pulmonary perfusion can increase during exercise with increasing the workload of right ventri. B.High distensiblity of pulmonary capillaries allow increase blood flow C. Pulmonary circulation operates at a low pressure of 15mm Hg on average D. None of the above is Incorrect ..
Which of the following statements best summarizes the function of the pulmonary circuit in a human circulatory system? Question 26 options: Filters waste products from the blood. Transports carbon dioxide to the lungs and picks up oxygen from the lungs. Transports oxygen through the heart, lungs and body tissues. Transports oxygen and nutrients to body tissues.
The blood vessels with venous blood proceeding from the right ventricle to the lungs are the Group of answer choices pulmonary capillaries AV valve pulmonary arteries pulmonary veins aorta
With the appearance of strong oxidizers in blood in erythrocytes one of the following substances is formed first of all: 1. carbhemoglobin 2. carboxyhemoglobin 3. oxyhemoglobin 4. methemoglobin 5. deoxyhemoglobin
The flow rule states that (substances) gases or liquids flow from a region of higher pressure to a region of lower pressure. This can be applied to any section of the respiratory tract. Use this information to explain why the Heimlich maneuver (a sharp compression of the abdominal cavity just below the diaphragm) can dislodge food or other objects lodged in the trachea of a choking person.
Which of the following structures is incorrectly paired with the type of blood it would be carrying? pulmonary artery / oxygen-poor blood inferior vena cava / oxygen-poor blood left ventricle / oxygen-poor blood aorta / oxygen-rich blood right atrium / oxygen-poor blood
