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.

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.

b. Located in the posterior cavity: The retina is a layer of tissue located in the posterior cavity of the eye. It contains photoreceptor cells that convert light into neural signals, which are then transmitted to the brain via the optic nerve.
c: Is the outermost layer of the eye - The outermost layer of the eye is the sclera, a tough, white layer that helps maintain the shape of the eye.
d: Produces aqueous humor - Aqueous humor is produced by the ciliary body and is found in the anterior chamber of the eye, not in the retina.
