Djurvävnad

Djurvävnad refers to the biological tissues found in animals. These tissues are groups of similar cells that are organized to perform a specific function within the body. There are four main types of animal tissues: epithelial tissue, connective tissue, muscle tissue, and nervous tissue. Epithelial tissue covers body surfaces and lines internal cavities and organs. Connective tissue supports, protects, and binds other tissues together, and includes bone, cartilage, blood, and adipose tissue. Muscle tissue is responsible for movement and is divided into skeletal, smooth, and cardiac muscle. Nervous tissue transmits electrical signals and comprises neurons and glial cells. Tissues are the building blocks of organs, which in turn form organ systems. The study of animal tissues is known as histology. Understanding the structure and function of djurvävnad is fundamental to comprehending animal physiology and pathology. Different animal species may exhibit variations in their tissue composition and organization based on their specific evolutionary adaptations and needs. The study of these tissues is crucial in fields such as veterinary medicine, zoology, and biomedical research.
