Right AV Conduction path Which of these represents atrial depolarization? a. P wave b. QRS complex c. T wave Which of these had no nucleus? a. RBC b. WBC c. Nuetrophils Which of these is the most abundant organic molecule in the blood? a. Carbon dioxide b. Plasma proteins c. platelets Of the 3 major plasma proteins we discussed, which of them contained three types? a. Albumin b. Globins c. Fibrinogen At any given point, in the right atrium you will find _________ a. O_2 poor blood b. O_2 rich blood C. CO_2 poor blood At any given point, in the pulmonary arteries, you will find ______ a. O_2 poor blood b. O_2 rich blood c. CO_2 poor blood At any given point, in the left ventricle, you will find _______ a. O_2 poor blood b. CO_2 poor blood c. CO_2 rich blood At any given point, in the left atria, you will find ____________Explanation / Answer
41. The correct answer is (C). Right Atrio Ventricular (AV) conduction path.
Tne AV node play a part of the electrical conduction system of the heart that coordinates the top of the heart. It connects the the right atrium and right ventricle through electrically. The AV node lies at the lower back section of the interatrial septum near the opening of the coronary sinus, which conducts the normal electrical impulse from the atria to the ventricles.
42. The correct answer is (A). P wave.
In the electrocardiogram (ECG), the first deflection is the P wave associated with right and left atrial depolarization. Wave of atrial repolarization is invisible in the ECG graph because of its low amplitude.
43. The correct answer is (A). RBC
Due to the lack or absence of nucleus in the Red Bllod Cells (RBC), it allows the RBC to contain more hemoglobin and, therefore, carry more oxygen molecules. It also allows the cell to have its distinctive bi-concave shape which aids diffusion.
44. The correct answer is (B). Plasma Protien
The non-cellular portion of blood is called the blood plasma. Plasma is about 90% water by weight. The plasma proteins make up three-fourths of the weight of solutes in plasma. Plasma protien have the capacity to transport important nutrients, such as lipids and fatty acids, as well as some trace metals, vitamins, and hormones. Total concentration of protien in the plasma in 5.8 - 8.0 g/100 mL.
45. The correct answer is (B). Globulin
Globulins serve as antibodies and transport substances. Globulins as a diverse group of proteins transport various substances in the blood and primarily are involved in defense mechanisms of the body. The normal concentration of globulins in human blood is about 2.6-4.6 g/dL.
46. The correct answer is (A). O2 poor blood
The heart pumps blood to all parts of the body. Blood provides oxygen and nutrients to the body and removes carbon dioxide and wastes. As blood travels through the body, oxygen is used up, and the blood becomes oxygen poor. Oxygen-poor blood returns from the body to the heart through the superior vena cava (SVC) and inferior vena cava(IVC), the two main veins that bring blood back to the heart. The oxygen-poor blood enters the right atrium (RA), or the right upper chamber of the heart.
47. The correct answer is (A). O2 poor blood
From, the right atrium, the oxygen-poor blood flows towards the the tricuspid valve (TV) into the right ventricle (RV), or the right lower chamber of the heart. Then, the right ventricle (RV) pumps oxygen-poor blood through the pulmonary valve (PV) into the main pulmonary artery (MPA).
48. The correct option is missing in this question.
The left ventricle pumps the blood from the left atrium out to the body, supplying all organs with oxygen-rich blood.
49. The left atria receives blood from the lungs, which is rich in oxygen
