Fibroblasts are the primary cells responsible for secreting collagen and elastin fibers in connective tissues.
Cartilage, Bone, Adipose tissue, and Areolar tissue: All contain fibroblasts or related cell types (chondrocytes in cartilage, osteoblasts in bone, adipocytes in adipose tissue) that produce collagen or elastin fibers.
Blood: Blood does not contain fibroblasts. Its matrix (plasma) contains various proteins, but these are not secreted by blood cells in the same way that fibroblasts secrete collagen and elastin.

Consider a water tank shown in the figure. It has one wall at \(x = L\) and can be taken to be very wide in the z direction. When filled with a liquid of surface tension \(S\) and density \( \rho \), the liquid surface makes angle \( \theta_0 \) (\( \theta_0 < < 1 \)) with the x-axis at \(x = L\). If \(y(x)\) is the height of the surface then the equation for \(y(x)\) is: (take \(g\) as the acceleration due to gravity)
A constant voltage of 50 V is maintained between the points A and B of the circuit shown in the figure. The current through the branch CD of the circuit is :
