Which one of the following animals has two separate circulatory pathways?
1. Frog
2. Lizard
3. Whale
4. Shark
Doctors use a stethoscope to hear the sounds produced during each cardiac cycle. The second sound is heard when:
| 1. | AV valves open up |
| 2. | Ventricular walls vibrate due to the gushing of blood from the atria |
| 3. | Semi-lunar valves close down after the blood flows into vessels from the ventricles |
| 4. | AV node receives a signal from SA node |
Blood pressure in the mammalian aorta is maximum during:
2. diastole of the right ventricle
3. systole of the left ventricle
4. diastole of the right atrium
Which one of the following is correct?
1. Serum = Blood + Fibrinogen
2. Lymph = Plasma + RBC + WBC
3. Blood = Plasma + RBC + WBC + Platelets
4. Plasma = Blood – Lymphocytes
The diagram given here is the standard ECG of a normal person, The P - wave represents the:
Person with blood group AB is considered as universal recipient because he has:
| 1. | both A and B antigens on RBC but no antibodies in the plasma |
| 2. | both A and B antibodies in the plasma |
| 3. | no antigen on RBC and no antigens in the plasma |
| 4. | both A and B antigens in the plasma but no antibodies |
How do parasympathetic neural signals affect the working of the heart?
| 1. | reduce both heart rate and cardiac output |
| 2. | Heart rate is increased without affecting the cardiac output |
| 3. | Both heart rate and cardiac output increased |
| 4. | Heart rate decreases but cardiac output increases |
Figure shows a schematic plan of blood circulation in humans with labels A to D. Identify the label and give its function/s.
| 1. | B-Pulmonary artery- takes blood from heart to lungs, PO2 = 90mm Hg |
| 2. | C-Vena Cava- takes blood from body parts to right auricle, PCO2 = 45mm Hg |
| 3. | D-Dorsal aorta- takes blood from heart to body parts, PO2 = 95mm Hg |
| 4. | A- Pulmonary vein - takes impure blood from body parts, PO2 = 60mm Hg |
