Smooth Muscals
IS found is in our visceral, or
hollow, organs.
Skelital Muscal
Is tissue found in our
in are skiletal muscal like
hte biceps.
Cardiac muscal
Carbohydrates:Suger and starches that give the body energey.
Proteins: Aniano acids connected together in different arrangements.
Minerals:
Vitamins:
Fats: gives the body energey, protects and cushion vital organs as well as joints.
Water:
It is the heart muscal, it is found in the walls of the heart.
1. Movment: mussals
contract,cause movement
at joints.
2. Posture: hold upright
3. Joint Stability: hold bones/
joints inplace and allows movoment.
4. Heat Production: Muscles
contract and cause blood
to flow to the area heat.
Calcium: helps build strong bones and teeth.
Diary and leafy vegetables.
Iron: Helps biuld hemoglobin whitch is the oxygen-carrying part of your red blood cells.
Potassium: Helps regulate fluid balance in the body, assists with the normal functions of the muscles and nerves.
Magnesium: Involved in the metabolism of proteins and carbohydrates, assists with bone growth and proper muscle functioning.
Vitamins: group of compounds the help you body mainain normal metabollism, grouth and development.
The excretory sysem filters blood.
Weter and solutes are forced though the capillareies.
The bad stuff gets removed and the good stuff filters back through the body and goes to places that did it.
Nose: to keep tissue healthy, air entering the restirateory system must be fillered,
Pharynx: Ar movie though the nose and to the cavity to the back of the mouth.
Larynx: the hollow muscular organ forming an air passage to the lungs and holding the vocal cords in humans and other mammals; the voice box.
Trachea: Air movies from the Pharynx to the windpipe.
4 parts of blood and Hemoglobin:
Circulatory System:
Lungs: the carbon deoxide is released from the cellular to the lungs and in the blood.
passes though the capillaries in the lungs and then it is exhaled.
Colon: They pass into the small intestin as bile, and are excreated as feces, as bile salt, from teh colon.
Skin: Sweet, witch is excreted thought the skin, contains water, salt and some urin.
as the water is leaveing the body, heat is lost and the body is cooled. So it basicaly cools the body down and regulats the temp.
5 functions:
1. transport oxygen to cells
2. transport Nutrients from the digestive system to body cells
3. transport hormones to body cells
4. transport waste from body cells to excretory organs.
5. Distribute body waste.
1. Plasma: Connective tissue that consists of cells in a water matrix.
2. Platelats: Cell Fragmants that minimize blood loss from the ruptured blood vessels by releasing material that assists in the formation of clots.
3. Red blood cells:Which are part of the immune system fight infection.
4. White blood cells: helps carry oxygen from the lungs to the rest of the body and then returns carbon dioxide from the body to the lungs.
the human respiratory system
picks up oxygen from the air we
inhale releases carbon beoxide into the air we exhale.
Chemical properties of blood and red blood cells allow for efficient transport of the gases toughout the body.
1. blood enters the right atrium
2. Passes through the tricuspid valve into the right ventricle.
3. Blood passes through the pulmonary valve into the pulmonary artery.
4. Enters lungs and drops off carbon dioxide,(wastes).
5.Blood picks up oxygen from the capillaries in the lungs.
6. Blood returns to the heart through the left pulmonary vein.
7. Blood enters the left atrium
8. Passes through the bicuspid valve and into the left ventricle.
9. Passes through the aortic valve and into the aorta to deliver oxygen around the body.
10.Makes a pit stop in the digestive system to pick up nutrients from the small intestine.
11. Drops off oxygen and nutrients to body cells.
12. Picks up carbon dioxide (wastes) from cells.
13. Travels on veins back to the heart.
14. Reenters the heart through the vena cava
1. It is a soft tissue occupying and cavity of the long bone.
2. Spongy bone contain bone marrow.
3. Compact bone protects that inside of the bone.
1. Flat bone ( skull )
2. long bone ( Femur )
3. Short bone ( wrist and ankles )
4. Irregular bone ( Pelvis )
1. Support: some of the bones support are vital organs.
2. Protection:the skill bone protects the brain.
3. Movement: Muscles use the bones to move up and down and right to left.
4. Reservoir for minerals and adipose tissue: 99% of the body's calcium is stored in bones.
5. Making blood cells:
All blood cells are mad from bone marrow that is in the center of the bone.
