Which of the following is the effect of inflammation in the healing process?
Pulls the edges of the wound together
Causes bleeding to clean out the wound
Cleans out debris and toxins from the wound
Builds the scab to protect the wound
The Correct Answer is C
a. Pulls the edges of the wound together: Wound closure is a later stage of healing, not a primary function of inflammation.
b. Causes bleeding to clean out the wound: While some bleeding might occur initially, inflammation doesn't actively cause bleeding to clean the wound.
c. Cleans out debris and toxins from the wound: Inflammation is a natural response to injury or infection. It involves increased blood flow, redness, swelling, and heat. This process helps to deliver white blood cells and other immune factors to the area to fight infection and remove debris and damaged tissues, promoting healing.
d. Builds the scab to protect the wound: Scab formation is a result of dried blood and plasma, not a direct effect of inflammation.

Correct Answer is A
Explanation
A. Loop of Henle:After the glomerular filtrate passes through the proximal convoluted tubule, it enters the Loop of Henle. This component of the nephron is responsible for further concentrating the filtrate and plays a critical role in urine concentration.
B. Bowman's capsule:Bowman's capsule is where glomerular filtration begins. It collects the filtrate from the glomerulus, but it is not where filtrate goes after the proximal convoluted tubule.
C. Collecting duct:The collecting duct is the final segment of the nephron where urine is collected after it has passed through the Loop of Henle and distal convoluted tubule. It does not receive the filtrate directly from the proximal convoluted tubule.
D. Glomerulus:The glomerulus is a network of capillaries where filtration of blood occurs, producing glomerular filtrate. It is not a component that the filtrate enters after the proximal convoluted tubule.
Correct Answer is B
Explanation
a. The plasma membrane is composed of a bilayer of protein molecules: This is incorrect. The plasma membrane is primarily composed of a bilayer of phospholipids, with proteins interspersed within this bilayer.
b. The plasma membrane is selectively permeable: This is correct. The plasma membrane regulates the entry and exit of substances, allowing certain molecules to pass while restricting others.
c. The plasma membrane does not participate in cellular activities: This is incorrect. The plasma membrane is actively involved in various cellular activities, including signaling, transport, and maintaining homeostasis.
d. The plasma membrane receptors are specialized lipids: This is incorrect. Receptors on the plasma membrane are typically proteins, not lipids, which are involved in signal transduction and cellular communication.
