In a wild tailgating incident at the Panthers game, Postman Bill accidentally stabbed Ronnie in the chest with a skewer from the grill. The skewer entered his left side and lodged in his heart. Please give the correct order of serous membranes through which the tip of the skewer passed.
1. visceral pleura
2. parietal pericardium
3. parietal pleura
4. visceral pericardium
1,3,3,1,2,4
3,1,1,3,4,2
1,3,3,1,4,2
3,1,1,3,2,4
The Correct Answer is D
A. 1,3,3,1,2,4: This order is illogical-it repeats pleura in an inconsistent pattern and places visceral pleura first.
B. 3,1,1,3,4,2: It ends with visceral pericardium followed by parietal, which is anatomically reversed.
C. 1,3,3,1,4,2: Starts with visceral instead of parietal and ends in the wrong order.
D. 3,1,1,3,2,4: This choice correctly represents the entry path: through parietal pleura (3) → visceral pleura (1) → lung → parietal pericardium (2) → visceral pericardium (4) → heart.

Correct Answer is B
Explanation
A. exocytosis: This is the process of expelling material out of the cell, not taking it in.
B. pinocytosis: Pinocytosis is "cell drinking"-the process of engulfing dissolved particles in fluid by invagination of the plasma membrane.
C. cytolysis: Cytolysis refers to cell bursting, not intake of particles.
D. phagocytosis: Phagocytosis is "cell eating", where the cell engulfs large solid particles like bacteria, not liquids.
Correct Answer is B
Explanation
A. a decrease in heart rate: Low oxygen usually triggers the body to increase heart rate to deliver more oxygen-not decrease it.
B. an increase in the respiratory rate: In negative feedback, low oxygen stimulates chemoreceptors which trigger an increase in respiratory rate to bring in more oxygen.
C. a decrease in the respiratory rate: This would worsen the low oxygen state, and is contrary to how the body responds.
D. A and C: Both options are inappropriate responses to low oxygen levels.
E. A and B: While B is correct, A is not, so this combination is also incorrect.
