Which of the following glands produces oil that lubricates hair follicles?

A. Release of renin: When blood pressure decreases, the kidneys respond by releasing renin, an enzyme that initiates the renin-angiotensin-aldosterone system (RAAS. . This system increases blood pressure by causing vasoconstriction and promoting sodium and water reabsorption.

B. Decrease in sodium reabsorption: A decrease in blood pressure would typically lead to an increase, not a decrease, in sodium reabsorption. This is because the body aims to retain sodium and water to increase blood volume and pressure.

C. Constriction of the efferent arteriole: While constriction of the efferent arteriole can help increase glomerular filtration rate (GFR. in the kidneys, it is not the primary response to a decrease in blood pressure. The release of renin is the initial and more direct response.

D. Dilation of the afferent arteriole: Dilation of the afferent arteriole can help increase blood flow to the kidneys and maintain GFR, but it is part of the local autoregulatory mechanisms. The systemic response to decreased blood pressure involves the release of renin.

A. Binds tissue together and supports structures: Connective tissue provides structural support and binds different tissues and organs together. It plays a key role in maintaining the integrity of organs and tissues, and includes various types such as bone, cartilage, and blood, which contribute to the overall framework and function of the body.

B. Contracts and brings about movement: This function is primarily associated with muscle tissue, not connective tissue. Muscle tissue is responsible for contraction and movement, including voluntary movements (skeletal muscle. and involuntary movements (cardiac and smooth muscle. .

C. Generates and transmits impulses: This describes the function of nervous tissue, which includes neurons and glial cells. Nervous tissue is responsible for generating and transmitting electrical impulses throughout the body.

D. Covers and lines body surfaces: This function is characteristic of epithelial tissue. Epithelial tissue forms protective layers and linings on body surfaces and cavities, rather than providing structural support like connective tissue.
