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 |
A certain road accident patient with an unknown blood group needs an immediate blood transfusion. His one doctor friend at once offers his blood. What was the blood group of the donor?
1. Blood group B
2. Blood group AB
3. Blood group O
4. Blood group A
1. | carry blood away from the heart to different organs |
2. | break up into capillaries which reunite to form a vein |
3. | carry blood from one visceral organ to another visceral organ |
4. | supply oxygenated blood to the different organs |
1. | 100/55 mmHg is considered an ideal blood pressure |
2. | 105/50 mmHg makes one very active |
3. | 190/110 mmHg may harm vital organs like the brain and kidney |
4. | 130/90 mmHg is considered high and requires treatment |
1. Type AB
2. Type O
3. Type A
4. Type B
1. Heart
2. Kidney
3. Pancreas
4. Brain
1. Serum amylase
2. A globulin
3. Fibrinogen
4. Albumin
If due to some injury the chordae tendineae of the tricuspid valve of the human heart is partially non-functional, what will be the immediate effect?
1. | The flow of blood into the aorta will be slowed down |
2. | The 'pacemaker' will stop working |
3. | The blood will tend to flow back into the left atrium |
4. | The flow of blood into the pulmonary artery will be reduced |
In a standard ECG, which one of the following alphabets is the correct representation of the respective activity of the human heart?
1. R-repolarisation of ventricles
2. S-start of systole
3. T-end of diastole
4. P-depolarisation of the atria
Compared to blood our lymph has:
1. no plasma
2. plasma without proteins
3. more WBCs and no RBCs
4. more RBCs and less WBCs
