Focuses on the two major tissue types: epithelial tissue, which lines surfaces and cavities, and connective tissue, which provides support and structure in the body.
Frogs are cold-blooded (poikilothermic) animals that regulate their body temperature by using external heat sources.

Squamous epithelium, which is thin and flat, lines the blood vessels in frogs to facilitate diffusion.

The kidney in frogs is responsible for excretion, osmoregulation, and blood filtration but not oxygen transport.

Frogs have adrenal glands, but they lack a distinct adrenal medulla like mammals.

The liver in frogs performs bile secretion, detoxification, and glycogen storage but does not produce red blood cells.

The frog's skeleton is made of bones, except for some cartilaginous structures in the developing tadpole.

Frogs do have adrenal glands, which help regulate stress responses and metabolism.

Frogs have an endoskeleton composed mainly of bones, providing structural support and aiding in movement.

The frog’s heart is composed of connective, muscular, and nervous tissues, but not epithelial tissue.

Frogs have an endoskeleton composed mainly of bones, supporting their body structure and movement.

The frog's skeleton is made primarily of bones, not cartilage.

Hemoglobin, present in frog’s RBCs, binds to oxygen and transports it throughout the body.
