(1)与激素一样,CO2也可以作为体液调节因子,参与体液调节,支持这一观点的事实之一是细胞代谢产生的CO2可通过
(2)盐酸不是体液调节因子,其原因是胃腺分泌的盐酸进入胃腔后,参与食物消化,且在这个过程中,胃腺分泌的盐酸经过导管到达胃腔不经过

y = sin x, x∈R, y∈[–1,1],周期为2π,函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x, x∈[–1,1], y∈[–π/2,π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
