The hormone ACTH is secreted by the anterior pituitary and targets the adrenal gland cortex. Which of the following corticosteroids (hormones made in the adrenal cortex) targets the kidney for the reabsorption of Na+ and secretion of K+?
a. ADH
b. aldosterone
c. cortisol
d. ANP
b. aldosterone
The hormone ANP is secreted by the heart and targets smooth muscles in the arteries and the distal convoluted tubule of the kidney. This specific hormone causes _______________________.
a. H2O to be reabsorbed in the kidney and K+ to be secreted into the urine.
b. K+ to be reabsorbed in the kidney and Na+ to be secreted into the urine.
c. Ca2 + to be reabsorbed in the kidney and H+ to be secreted into the urine.
d. Na+ to be reabsorbed in the kidney and K+ to be secreted into the urine.
b. K+ to be reabsorbed in the kidney and Na+ to be secreted into the urine.
ADH is synthesized in the hypothalamus and targets the smooth muscle in the arteries to cause _____________________.
a. vasodilation and decrease systemic pressure.
b. vasoconstriction and increase systemic blood pressure
c. increased inflammation and vasodilation.
d. necrosis and death of the tissue.
b. vasoconstriction and increase systemic blood pressure
OT synthesized in the hypothalamus and stored in the posterior pituitary targets _______________.
a. the cardiac muscle to increase contractility
b. the penis in males to cause an erection
c. the uterus in females to cause smooth muscle contraction during childbirth
d. the urinary bladder to increase fluid pressure during urination.
c. the uterus in females to cause smooth muscle contraction during childbirth
In order to increase target cell activation by a hormone the cell can upregulate (increase the number) of _________________.
a. ribosomes
b. nuclei
c. mitochondria
d. receptors
d. receptors
______________ is a failure of the adrenal cortex to synthesize aldosterone and cortisol.
a. Congestive Heart Failure (CHF)
b. Addison’s Disease
c. Chronic Obstructive Pulmonary Disease (COPD)
d. Cushing’s Syndrome
b. Addison’s Disease
Renin secreted by the kidney in response to low blood pressure triggers ___________.
a. RAS (Renin-Angiotensin System/Mechanism) to make Angiotensin-II that increases systemic blood pressure and stimulates secretion of aldosterone to reabsorb more Na+.
b. erythropoietin to be secreted by the kidney and stimulate erythrocyte production in the red bone marrow.
c. RAS (Renin-Angiotensin System/Mechanism) to secrete ADH from the liver and increase blood pressure.
d. OT to be secreted by the posterior pituitary and stimulate smooth muscle contraction of the uterus.
a. RAS (Renin-Angiotensin System/Mechanism) to make Angiotensin-II that increases systemic blood pressure and stimulates secretion of aldosterone to reabsorb more Na+.
The three steps of homeostasis are _________________.
a. vascular spasm > platelet plug formation > coagulation.
b. megakaryocyte formation > platelet plug formation > vascular spasm
c. coagulation > agglutination > Rh factor formation
d. platelet plug formation > coagulation > hemocytoblast differentiation
a. vascular spasm > platelet plug formation > coagulation.
If a blood sample agglutinates when tested with anti-B antibodies, then _______.
a. the A antigen is present and the blood type is A
b. the blood type is O
c. there are no antigens present
d. the B antigen is present and the blood type is B
d. the B antigen is present and the blood type is B
If an individual with blood type B receives blood from a donor with blood type O, then _____________________.
a. there will be no transfusion reaction because O is the universal donor
b. there will be no transfusion reaction because B is the universal recipient
c. there will be a transfusion reaction because the blood types do not match.
d. there will be a transfusion reaction because B can only receive from AB.
a. there will be no transfusion reaction because O is the universal donor
