Presentation on theme: "The Systems of the Human Body"— Presentation transcript:
1 The Systems of the Human Body Can you guess how many different system make up the Human Body?Well….the correct number is 11!! 11 different systems all working together for you to function.How many do you know out of those 11?We will go over all 11 in today’s lecture!
2 Levels of Organization Lets review…What are the levels of organization within a single human body??Atoms/MoleculesCellsTissuesOrgansSystemsOrganisms/Individual
7 Bones, ligaments, tendons, and cartilage. Provides frameworks, protective shield for softer tissue, attachment for muscles, and act together with muscles for movementTissue within the bones produce blood cells, store inorganic salts.
9 MUSCULAR SYSTEM All muscles… Smooth, cardiac, and skeletal.. Force for body movement, help maintain posture, are the main source of body heat.Aids in circulation of blood and food throughout the body.
11 NERVOUS SYSTEM Brain, spinal cord, nerves, and sense organs. Nerve cells send nerve impulsesSpecialized sensory receptors.Some nerves receive/send impulsesSome carry impulses from the brain or spinal cord to muscles
12 NERVOUS SYSTEM The basic unit of the nervous system are neurons. There are 3 types: sensory, motor, and interneurons!
16 CIRCULATORY SYSTEMIncludes heart, arteries, veins, capillaries, and bloodHeart-pump that forces blood through blood vessels.Blood- carries oxygen from lungs and nutrients from digestive organs to all body cells
17 CIRCULATORY SYSTEM Heart-pump that forces blood through blood vessels. Blood- carries oxygen from lungs and nutrients from digestive organs to all body cellsThese are red blood cells!They are the most numerous cells in the body.These cells transport oxygen.The cells actually have no nuclei.They live in the human body for about 120 days!
19 Lymphatic/Immune System Function: Helps to protect the body from diseaseCollects fluid lost from blood vessels & returns the fluid to the circulatory system.Structures: White blood cells, thymus, lymph nodes, lymph vessels
21 Digestive SystemIncludes: Mouth, tongue, teeth, salivary glands, pharynx, esophagus, stomach, liver, gallbladder, pancreas, small and large intestineBreaks down food to similar forms that can pass through cell membranes to be absorbed..
22 Digestive SystemMaterials not absorbed are transported back outside the body. (Primarily the job of your colon)Certain digestive organs produced hormones and function as part of the endocrine system.
26 Excretory/Urinary System Primarily includes kidney, ureters, urinary bladder, and urethaSome resources include lungs & skinKidneys remove wastes from blood and assist in maintaining the body’s water and electrolyte balanceProduct is urine
28 Reproductive System Female Ovaries, uterine tubes, uterus, vagina, clitoris, vulvaFunction: Produce and maintain egg cells, receive sperm cells, support development of an embryo and function in birth process
29 Reproductive System Male Scrotum, testes, epididymides, vasa deferentia, seminal vesicles, prostate gland, bulbourethral glands, urethra, and penisFunction: Produce and maintain sperm cells, transfer sperm cells into female reproductive organs.
