Lymphatic system collects lymph - a fluid derived from interstitial fluid B. Fluid enters lymphatic system via lymphatic capillaries C. Lymph fluid is inspected by white blood cells in lymph nodes for the presence of pathogens D. Lymph is drained into arteries Myoglobin has higher affinity to Oxygen than Hemoglobin (1) A. True B. False Respiratory control centers are located (1) A. In the right lung B. In the motor area of the cortex C. In the hypothalamus D. In the brainstem Mature red blood cell have the following: A. Nucleus B. Mitochondria C. Protein synthesizing machinery D. Hemoglobin E. All of the above Atrial contraction occurs between the following markers on the ECG (1)? A. P-wave and T-wave B. QRS-complex and T-wave C.T-wave and the following P-wave D. P-wave and QRS-complex E. QRS complex and the following P-wave What temperature do you expect to measure in a normal subject who just spent 15 minutes in a sauna room heated to 90°C (200 °F) (1)? A. 30 to 40°C (86 to 104°F) B. 40 to 50°C (104 to 124°F) C. 50 to 70°C (124 to 158°F) D. 70 to 90°C (158 to 200°F) E. >90°C (>200°F)

Answer 1

Ans1:- c) right ventricle.

Rt ventricle send blood to lung via pulmonary artery.

Ans2:- D) lymph is drain into artery

No lymph is not drain into artry it is drain into junction of subclavian and internal jugular vein via lymphatic trunks.

All other statement are right.

Ans3:-True

Myoglobin have higher affinity for oxygen the Heamiglobin .

It is clearly from the hyperbolic curve of oxygen saturation for myoglobin . And s shape curve for Haemoglobin.

Ans4:- d) in brainstem in medulla.

Dorsal respiratory gr and ventral respiratory gr of neuron.

Ans5:- d) Haemoglobin

Ans6:- d)

Ans7:- a)

Due to temp homeostasis mechanism
