20-23 Match the immune system cell type with its function or description:
a)B lymphocyte b)plasma cell c)T helper lymphocyte d)macrophage
20) is specifically attacked and destroyed by HIV
21) engulfs particles (phagocytosis) & causes inflammation
22) binds specific antigens to initiate an antibody response
23) makes antibodies in large quantities
24) The hormone essential to the maintenance of pregnancy is a)estradiol b)progesterone c)LH d)FSH
25) Growth hormone is the tropic hormone that stimulates the
a)thyroid b)adrenal cortex c)islets of Langerhans d)liver
26) In a kidney nephron, most of the water filtered through the glomerulus into the capsule is reabsorbed from
the a)proximal tubule b)distal tubule c)collecting duct d)loop of Henle
Ans- 20) is specifically attacked and destroyed by HIV-plasma cell
21) engulfs particles (phagocytosis) & causes inflammation-macrophage
22) binds specific antigens to initiate an antibody response-T helper lymphocyte
23) makes antibodies in large quantities- B lymphocyte
24)Progesterone
High levels of progesterone are required throughout pregnancy with levels steadily rising until the birth of the baby. During the first few weeks of pregnancy, progesterone produced from the corpus luteum (a temporary endocrine gland of the ovaries) is sufficient to maintain pregnancy.
25) Liver
The major role of growth hormone in stimulating body growth is to stimulate the liver and other tissues to secrete IGF-I.IGF-I stimulates proliferation of chondrocytes (cartilage cells), resulting in bone growth.
26) Proximal convoluted tubule
Reabsorption takes place mainly in the proximal convoluted tubule of the nephron. Nearly all of the water, glucose, potassium, and amino acids lost during glomerular filtration reenter the blood from the renal tubules
