Human digestive system 🔥

@SmartDoctor1 =============== The human body is a complex organism composed of several systems that work together to maintain homeostasis and carry out various functions. Here’s an overview of the major systems and their main components: Skeletal System: Bones: Provide support, protect organs, and allow for movement. Joints: Where bones meet and allow for articulation and movement. Muscular System: Skeletal Muscles: Responsible for movement, posture, and generating heat. Circulatory System: Heart: Pump that circulates blood throughout the body. Blood Vessels: Arteries, veins, and capillaries that transport blood. Blood: Carries oxygen, nutrients, hormones, and waste products. Respiratory System: Lungs: Responsible for the exchange of oxygen and carbon dioxide. Trachea: Windpipe that connects the lungs to the throat. Diaphragm: Muscle involved in breathing. Digestive System: Mouth: Where digestion begins with chewing and saliva production. Esophagus: Tube that carries food from the mouth to the stomach. Stomach: Organ that breaks down food through digestion. Small Intestine: Absorbs nutrients from digested food. Large Intestine: Absorbs water and forms feces. Nervous System: Brain: Control center of the body, responsible for cognition and coordination. Spinal Cord: Transmits signals between the brain and the rest of the body. Nerves: Carry signals to and from different parts of the body. Endocrine System: Glands: Secrete hormones that regulate bodily functions. Hormones: Chemical messengers that travel through the bloodstream. Urinary System: Kidneys: Filter waste products from the blood and regulate fluid balance. Bladder: Stores urine before elimination. Ureters: Tubes that carry urine from the kidneys to the bladder. Urethra: Tube through which urine is expelled from the body. Reproductive System: Male: Includes testes, penis, and associated structures. Female: Includes ovaries, uterus, fallopian tubes, and vagina. Integumentary System: Skin: Protects internal organs, regulates temperature, and receives sensory information. Hair and Nails: Provide protection and assist with sensory functions. These systems work together to maintain the body’s overall health and functionality. It’s important to note that this is a simplified overview, and each system has many more components and functions. =============== Follow us on the @SmartDoctor1 digital platform =============== ▶ Facebook ▶ ▶ Instagram ▶ ▶ TikTok ▶ @ ▶ twitter ▶ ============= Smart Doctor 👨‍⚕️ @SmartDoctor1/youtube ============= #anatomy #heart #smoker #lunges #lungs #uterusproblem #fetal #love #tongue #muscles #muscle #skull #humanskull #baby #fetaldevelopment #fetal #fetalmovement #fetalecho #heart #baby brain #shorts #viral #the_voice #thevoice #voice #voiceover #SmartDoctor1 #Smart #smart #Smart_Doctor #smartdoctor #oxygen #blood #body #the_voice #thevoice #voice #voiceover #pregnancy #medicina #anatomy #doctor #america #माहवारी #月経 #임신 #妊娠 #pregnant #gravidez #information
