Human Body Tissues and Functions

Ms. Swanson introduces the four basic human tissues: muscle, nervous, epithelial, and connective. She explains their structures, functions, and roles in the human body. Muscle tissue is divided into skeletal, smooth, and cardiac types, each with distinct characteristics and functions. Nervous tissue is responsible for communication through neurons. Epithelial tissue covers and lines body surfaces, playing roles in protection and absorption. Connective tissue supports and connects body parts, with blood classified as a type. The video concludes with a review of the learning goals.
