The skin and blood play crucial roles in the functioning of animals.
Skin: 1. Protection: The skin acts as a barrier that protects the internal organs and tissues from physical damage, pathogens, and harmful substances. 2. Regulation of body temperature: The skin helps regulate body temperature by controlling the loss of heat through sweating and the constriction or dilation of blood vessels. 3. Sensation: The skin contains sensory receptors that allow animals to perceive touch, pressure, temperature, and pain. 4. Vitamin D synthesis: The skin plays a role in the production of vitamin D when exposed to sunlight.
Blood: 1. Transportation: Blood carries oxygen, nutrients, hormones, and waste products to and from cells throughout the body. 2. Regulation: Blood helps regulate body temperature, pH levels, and fluid balance. 3. Immunity: Blood contains white blood cells that help defend the body against pathogens and foreign substances. 4. Clotting: Blood contains platelets and proteins that help form blood clots to prevent excessive bleeding when a blood vessel is damaged.

Skin
- Protection: Forms a barrier against physical trauma, pathogens, and UV radiation. - Thermoregulation: Regulates body temperature through sweating, shivering, and vasodilation/vasoconstriction. - Sensation: Contains sensory receptors for touch, temperature, and pain. - Excretion: Sweat glands release excess salt and water through perspiration. - Synthesis: Produces vitamin D through exposure to sunlight. - Communication: Displays coloration, patterns, and other physical adaptations for mating, camouflage, and warning.
Blood
- Transport: Carries oxygen, nutrients, hormones, and waste products throughout the body. - Regulation: Maintains body temperature, pH, and ionic balance. - Protection: Contains white blood cells and antibodies to fight infections. - Clotting: Forms blood clots to prevent excessive bleeding from wounds. - Lubrication: Plasma provides lubrication for joints and organs. - Waste Removal: Transports carbon dioxide and other waste products to the respiratory and excretory systems for removal.
