Human Body Systems : 

Human Body Systems

Levels of Organization in the Body : 

Levels of Organization in the Body Cells Tissues Epithelial, connective, muscular, nervous Organs Examples include stomach, liver, heart Organ Systems Examples include digestive and circulatory systems

Tissues in the Human Body : 

Tissues in the Human Body Epithelial Covering or lining tissue Connective Joins, stores and supports Muscle Internal and external movement Nerve Conducts electrical signals Blood Muscle Nerve

Human Organ Systems : 

Human Organ Systems Skeletal Muscular Circulatory Immune Respiratory Digestive Excretory Reproductive Nervous Endocrine Integumentary

Human Skeletal System : 

Human Skeletal System Functions Framework and support Protection Storage Axial and appendicular skeleton Bone structure Joints and ligaments

Human Skeleton Diagram :

Human Muscular System : 

Human Muscular System Functions Movement Warmth Posture Muscle Properties Ability to contract Ability to be stretched Ability to respond to a stimulus Muscle Types Skeletal Smooth Cardiac

Three Types of Human Muscle Tissue : 

Three Types of Human Muscle Tissue Skeletal Cardiac Smooth

Skeletal Muscle Contraction : 

Skeletal Muscle Contraction Myosin Actin Sarcomere

Human Circulatory System : 

Human Circulatory System Transports nutrients, gases, wastes, water, and hormones and also distributes heat Structures of circulatory system Heart Vessels Blood Lymphatic system Erythrocytes White blood cells

Diagram of Human Heart :

Human Immune System : 

Human Immune System Nonspecific defense responses Skin and mucous membranes Inflammatory response Temperature Proteins White blood cells Specific immune responses Humoral immunity Cell-mediated immunity

Disease Prevention in Humans : 

Disease Prevention in Humans Identifying Pathogens - Koch’s Postulates Vaccination - Edward Jenner Disorders Allergies Autoimmune disease Acquired Immune Deficiency Syndrome

Human Respiratory System : 

Human Respiratory System Respiration is gas exchange between an organism and the environment Respiratory structures include the nose, pharynx, larynx, trachea, bronchi, bronchioles and alveoli Mechanics of Breathing Respiratory Diseases Exhalation Inhalation

Human Respiratory System Diagram :

Human Digestive System : 

Human Digestive System Digestion is the breakdown of nutrients to a level that can be used by cells of the body. Structures GI tract (mouth, pharynx, esophagus, stomach, small intestine, large intestine) Accessory (teeth, tongue, salivary glands, liver, gall bladder, pancreas) Nutrition

Human Digestive System Diagram :

Human Excretory System : 

Human Excretory System Excretion is the removal of metabolic wastes from the body, including toxic chemicals, excess water, carbon dioxide and salts. Excretory Organs Skin Lungs Kidneys

Human Urinary System Diagram : 

Human Urinary System Diagram

Human Reproductive System : 

Human Reproductive System Produces gametes (eggs and sperm) Fertilization – produce zygote Male Reproductive System Testes Epididymus, vas deferens, urethra, seminal vesicle, prostate gland, Cowper’s gland Female Reproductive System Ovary Fallopian tubes, uterus, vagina

Human Male Reproductive System : 

Human Male Reproductive System Urinary bladder Vas deferens Prostate gland Urethra Penis Seminal vesicle Epididymus Testis

Human Female Reproductive System : 

Human Female Reproductive System

Human Endocrine System : 

Human Endocrine System The endocrine system consists of ductless glands that produce hormones. Hypothalamus, pituitary, pineal, thyroid, parathyroid, thymus, adrenal, pancreas, ovary, testes Hormones are chemical messengers that travel through the blood stream and affect activities throughout the body. Steroid hormones Nonsteroid hormones

Human Nervous System : 

Human Nervous System Controls and coordinates functions throughout the body Neurons are specialized cells that transmit impulses throughout the body. Nervous System Central Nervous System Peripheral Nervous System Somatic Autonomic

Human Neuron Diagram :

Human Integumentary System : 

Human Integumentary System Consists of the skin, hair, and nails Skin Epidermis Dermis Subcutaneous tissue Hair and nails

Homeostasis: Regulating the Internal Environment : 

Homeostasis: Regulating the Internal Environment A controlled, stable internal environment Gains and losses must balance Control systems Receptor, control center, effector Feedback loops Negative feedback Positive feedback
