Question

question 16
1 pts
neutrophils are highly mobile and phagocytic. they migrate out of blood vessels and into tissue spaces. this process is called
diapedesis.
chemotaxis.
erythroblastosis.
hematopoiesis.

question 17
1 pts
which are the two baroreceptors that are located near the heart?
coronary baroreceptors and aortic baroreceptors
aortic baroreceptors and carotid baroreceptors
carotid baroreceptors and venous baroreceptors
aortic baroreceptors and pulmonary baroreceptors

question 18
1 pts
a glycoprotein hormone that is secreted to increase oxygen concentration in the tissues is
erthropoietin.
hemoglobin.
spectrin.
proerythroblast.

Explanation:

• Question 16: Neutrophils migrating out of blood vessels into tissue spaces is called diapedesis. Chemotaxis is movement towards a chemical stimulus, erythroblastosis is related to red - blood - cell disorders, and hematopoiesis is blood cell formation.
• Question 17: The two baroreceptors near the heart are aortic baroreceptors (in the aortic arch) and carotid baroreceptors (in the carotid sinus). Coronary, venous, and pulmonary baroreceptors are not the main ones near the heart in the context of standard baroreceptor knowledge.
• Question 18: Erythropoietin is a glycoprotein hormone that stimulates red blood cell production (increasing oxygen - carrying capacity in tissues). Hemoglobin is a protein in red blood cells, spectrin is a cytoskeletal protein, and proerythroblast is an immature red - blood - cell precursor.

Answer:

• Question 16: diapedesis
• Question 17: aortic baroreceptors and carotid baroreceptors
• Question 18: erythropoietin
