  In this article, starting with results from a paper by Cammaroto and
Ko\v{c}inac in 1993, we prove that $t_{\theta}(X) = t_{\theta}(X_{s}) =
t(X_{s}) = F_{\theta}(X) = F_{\theta}(X_{s}) = F(X_{s})$ for every H-closed and
Urysohn space and we present some useful examples to study the full
relationships among the cardinal functions $t$, $t_{\theta}$, $F$ and
$F_{\theta}$ in the context of H-closed and Urysohn spaces. Also, we construct
an H-closed space $H$ for which $F_{\theta}(H) < t_{\theta}(H)$. Two questions
posed by Cammaroto and Ko\v{c}inac about H-closed spaces are answered.
