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!
Levels of Organization
• Lets review…What are the levels of organization within a single human body??
• Atoms/Molecules
• Cells
• Tissues
• Organs
• Systems
• Organisms/Individual
Integumentary System
Integumentary System
• Skin, hair, nails, sweat glands, and sebaceous glands.
• Protect underlying tissue, help regulate temp, sensory receptors, and synthesize certain products.
Integumentary System
Integumentary System
•Bones, ligaments, tendons, and cartilage.
• Provides frameworks, protective shield for softer tissue, attachment for muscles, and act together with muscles for movement
• Tissue within the bones produce blood cells, store inorganic salts.
MUSCULAR SYSTEMMUSCULAR 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.
MUSCULAR SYSTEMMUSCULAR SYSTEM
NERVOUS SYSTEMNERVOUS SYSTEM
• Brain, spinal cord, nerves, and sense organs.
• Nerve cells send nerve impulses
• Specialized sensory receptors.
• Some nerves receive/send impulses
• Some carry impulses from the brain or spinal cord to muscles
NERVOUS SYSTEMNERVOUS SYSTEM
NERVOUS SYSTEMNERVOUS SYSTEM
• The basic unit of the nervous system are neurons.
• There are 3 types: sensory, motor, and interneurons!
ENDORCRINE SYSTEM
• Function: Controls growth, development, and metabolism.
• Maintains Homeostasis
• ORGANS- Pituitary, thyroid, parathyroid, and adrenal glands, pancreas, ovaries, testes, pineal gland, and thymus gland
ENDORCRINE SYSTEM
CARDIOVASCULAR SYSTEM
• Includes heart, arteries, veins, capillaries, and blood
• Heart-pump that forces blood through blood vessels.
• Blood- carries oxygen from lungs and nutrients from digestive organs to all body cells
CIRCULATORY SYSTEM
• These 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!
• Heart-pump that forces blood through blood vessels.
• Blood- carries oxygen from lungs and nutrients from digestive organs to all body cells
CIRCULATORY SYSTEM
Lymphatic/Immune Lymphatic/Immune SystemSystem
• Function: Helps to protect the body from disease
• Collects fluid lost from blood vessels & returns the fluid to the circulatory system.
• Structures: White blood cells, thymus, lymph nodes, lymph vessels
Lymphatic/Immune Lymphatic/Immune SystemSystem
Digestive SystemDigestive System
• Includes: Mouth, tongue, teeth, salivary glands, pharynx, esophagus, stomach, liver, gallbladder, pancreas, small and large intestine
• Breaks down food to similar forms that can pass through cell membranes to be absorbed.
.
Digestive SystemDigestive System
• Materials 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.
Digestive SystemDigestive System
The Respiratory System
• Includes: Nasal cavity, pharynx, larynx, trachea, bronchi, and lungs
• Function: Takes air in and out and exchanges gases between blood and the air. (O2 in and CO2 out )
The Respiratory System
Excretory/Urinary Excretory/Urinary SystemSystem
Urinary System Urinary System
• Primarily includes kidney, ureters, urinary bladder, and uretha
• Some resources include lungs & skin
• Kidneys remove wastes from blood and assist in maintaining the body’s water and electrolyte balance
• Product is urine
Excretory/Urinary Excretory/Urinary SystemSystem
Reproductive SystemReproductive System
• Ovaries, uterine tubes, uterus, vagina, clitoris, vulva
• Function: Produce and maintain egg cells, receive sperm cells, support development of an embryo and function in birth process
Reproductive SystemReproductive SystemFemaleFemale
• Scrotum, testes, epididymides, vasa deferentia, seminal vesicles, prostate gland, bulbourethral glands, urethra, and penis
• Function: Produce and maintain sperm cells, transfer sperm cells into female reproductive organs.
