The Digestive SystemFunction: to convert food particles into simple

molecules that can be absorbed into the blood and used by the body

Major Organs and their Functions:

Mouth – to chew and grind up food (mechanical)

-- amylase in the saliva begins the chemical breakdown

Esophagus – pipe connecting mouth to stomach

Stomach – secretes pepsin, an enzyme that breaks down food. The stomach has a pH of 2.

•SMALL INTESTINE – AFTER DIGESTION IS COMPLETE, THE CHYME (PROCESSED STOMACH CONTENTS) ENTERS THE SMALL INTESTINE WHERE IT IS ABSORBED INTO THE BLOODSTREAM BY THE HELP OF SMALL HAIRS CALLED VILLI.

• LARGE INTESTINE – REMOVES WATER FROM THE CHYME AND GETS THE WASTE READY FOR EXCRETION

THE NUTRIENTS THAT ARE ABSORBED DURING DIGESTION TRAVEL INTO THE CIRCULATORY SYSTEM TO BE DISTRIBUTED THROUGH THE BODY!

Liver – produces bile, which breaks down fats in foods. This is an accessory organ.

Gallbladder – pouch-like organ that stores bile for future use

The Digestive System

Bacteria in the intestines of cows, ruminants and other animals helps digestion take place

by breaking down food.

EXPLAIN HOW THE DIGESTIVE SYSTEM WORKS CLOSELY WITH THE:

CIRCULATORY SYSTEM

MUSCULAR SYSTEM

ENDOCRINE SYSTEM

The Respiratory SystemFunction: to provide the body with a fresh supply of

oxygen for cellular respiration and remove the waste product carbon dioxide

MAJOR ORGANS

•NOSE – INTERNAL ENTRY AND EXIT POINT FOR AIR

• TRACHEA – THE “WINDPIPE”

•BRONCHIAL TUBES – THE TWO LARGE PASSAGEWAYS THAT LEAD FROM THE TRACHEA TO YOUR LUNGS (ONE FOR EACH LUNG)

•ALVEOLI – CLUSTERS OF TINY SACS WHERE GASES ARE EXCHANGED WITH THE BLOODSTREAM.

Diaphragm - the muscle that causes you to breath

Cilia – tiny hairs that line the air passages that trap tiny particles

The Circulatory SystemFunction: to deliver oxygen to the body and brain; to deliver nutrients from the digestive system.

Image of the Circulatory System

MAJOR ORGANS • HEART – THE MAJOR MUSCLE OF THE CIRCULATORY SYSTEM

• PUMPS BLOOD THROUGH ITS FOUR CHAMBERS (TWO VENTRICLES AND TWO ATRIA)

• PUMPS DEOXYGENATED BLOOD INTO THE LUNGS, WHERE IT GETS OXYGENATED, RETURNS IT TO THE HEART, AND THEN PUMPS OUT THROUGH THE AORTA TO THE REST OF THE BODY

• VALVES REGULATE THE FLOW OF BLOOD BETWEEN THE CHAMBERS

Arteries – carry blood away from the heart and to the major organs of the body

Veins – carry blood back to the heart away from the major organs of the body

Capillaries – small blood vessels (one cell thick) where gas exchange occurs, connects arteries and veins

RED BLOOD CELLS: CONTAIN HEMOGLOBIN; CARRIES OXYGEN THROUGHOUT BODY

WHITE BLOOD CELLS: FIGHT DISEASE

PLATELETS: FRAGMENTS THAT HELP BLOOD CLOT

PLASMA: LIQUID PART OF THE BLOOD

• HEMOGLOBIN IS A PROTEIN IN RED BLOOD CELLS THAT CARRIES OXYGEN THROUGHOUT THE BODY.

NOW LETS SEE HOW

THESE SYSTEMS

WORK TOGETHERYOU WILL HAVE 1O MINUTES TO FINISH YOUR

• EXERCISE (YOU CAN DO JUMPING JACKS, PUSH UPS, OR JOG QUICKLY IN PLACE FOR 1 MINUTE.

• TAKE PULSE AGAIN (COUNT BEATS FOR 15SECONDS AND MULTIPLY NUMBER BY 4. RECORD THE NUMBER UNDER AFTER EXERCISE COLUMN)

DIGESTIVE SYSTEM IN A BAG• 1. PLACE CRACKER IN BAG

• POUR A SMALL AMOUNT OF SPRITE IN BAG

• SEAL BAG CLOSED

WORDS HOW THE

RESPIRATORY, CIRCULATORY,

AND DIGESTIVE SYSTEM WORK

TOGETHER IN NUTRIENT

REPRODUCTIVE AND ENDOCRINE SYSTEM

BELL RINGER

HEALTH-CARE WORKERS ARE EXPOSED TO

MANY DIFFERENT TYPES OF PATHOGENIC AND

NONPATHOGENIC MICROORGANISMS. WHICH

BODY SYSTEMS WORK TOGETHER TO PROTECT

THE BODY FROM PATHOGENS?

A  MUSCULAR AND VASCULAR

B  DIGESTIVE AND EXCRETORY

C  CIRCULATORY AND IMMUNE

D  ENDOCRINE AND REPRODUCTIVE

•FUNCTION: THE REPRODUCTIVE SYSTEM HELPS HUMANS REPRODUCE AND ENSURES THE SURVIVAL OF THE SPECIES.

REPRODUCTIVE SYSTEM

•THE PRIMARY FEMALE REPRODUCTIVE ORGANS ARE THE OVARIES, AND THE PRIMARY MALE REPRODUCTIVE ORGANS ARE THE TESTES.

•OVARIES PRODUCE THE FEMALE HORMONES ESTROGEN AND PROGESTERONE AND THE TESTES PRODUCE TESTOSTERONE.

•THROUGH MEIOSIS, THE FEMALE (EGGS) AND MALE (SPERM) GAMETES ARE PRODUCED. THEY HAVE HALF THE NUMBER OF CHROMOSOMES AS OTHER CELLS (HAPLOID).

•WHEN AN EGG AND SPERM FUSE, FERTILIZATION TAKES PLACE AND A ZYGOTE IS FORMED. IT DEVELOPS INTO AN EMBRYO WHICH BECOMES A BABY.

•SPERM CELLS HAVE FLAGELLA

• FOR MOVEMENT

• EACH MONTH, AN EGG IS RELEASED BY ONE OF THE 2 OVARIES. IF FERTILIZATION OCCURS, IT WILL OCCUR IN THE OVIDUCT.

• THE FERTILIZED EGG (ZYGOTE) TRAVELS TO THE UTERUS AND IMPLANTS INTO THE UTERINE WALL. THE FETUS WILL DEVELOP IN THE UTERUS FOR 9 MONTHS.

The Endocrine SystemFunction: to control growth, development, metabolism and reproduction through the

production and secretion of hormones

Major Organs

Pancreas: secretes insulin which regulates blood sugar

Pituitary gland (brain): secretes growth hormone

Thyroid: regulates metabolism

Adrenal Glands: prepare body for fight or flight

Testes & Ovaries: produce sex hormones

Which of the following correctly describes an interaction that occurs between two body systems of a rabbit that helps the rabbit outrun a pursuing coyote?

F The skeletal system releases additional calcium, and the circulatory system retains more sodium in the blood to provide muscles with ions for contraction.

G The digestive system increases the rate of digestion, and the excretory system ceases to provide tissues with more nutrients.

H The respiratory system increases the breathing rate, and the circulatory system increases blood pressure to provide tissues with more oxygen.

J The endocrine system releases hormones that prepare the immune system to deal with possible injuries.

DAILY OBJECTIVE

• WE WILL DESCRIBE THE INTERACTIONS AMONGST THE MUSCULAR AND SKELETAL SYSTEMS.

• HTTP://GPISD.DISCOVERYEDUCATION.COM/PLAYER/VIEW/ASSETGUID/C560616C-CF6A-488A-A0F2-A41A54965204

The Skeletal System

Purpose: to provide structure and support to the human body

Bones are where new blood cells are generated (in the marrow), and require the mineral calcium for strength

Major Bones of the Human Body

-- femur (thigh bone) -- humerus (upper arm)

-- radius and ulna (lower arm) -- cranium (skull)

-- sternum (breastbone) -- clavicle (shoulder blade)

-- fibula and tibia (calf) -- vertebrae (back)

-- scalpula (shoulder) -- pelvic bone

-- coccyx (tail bone) -- phalanges (fingers/toes)

Challenge Question!!!!

The Muscular System

Purpose: works with the skeletal and nervous system to produce movement, also helps to circulate blood through the human body

-- muscle cells are fibrous

-- muscle contractions can be voluntary or involuntary

Major Muscles in the Human Body

-- biceps (flexor) -- triceps (extend)-- deltoids

-- glutes -- hamstrings --quadriceps

Challenge Question!!!!

The Excretory System

Kidneys-Ureter-Bladder-Urethra

Function: to rid the body of wastes, including excess water

and salts

Major Organs of excretion

Kidneys – the main organ of the excretory system; excretion begins here

-- Kidneys filter the blood, removing wastes

MORE EXCRETORY ORGANS:•SKIN – SWEAT GLANDS REMOVE EXCESS WATER AND SALTS FROM THE BODY

•LUNGS – EXPEL THE WASTE PRODUCT CARBON DIOXIDE (CELLULAR RESPIRATION)

•QUESTION: CAN ONE ORGAN BE PART OF TWO SYSTEMS?
