What is the purpose of the cardiovascular system?

-Carries out materials like oxygen and nutrients to cells


-Gets rid of carbon dioxide from cellular respiration


-fights diseases with white blood cells

What does The heart do?

Cardiac muscles that pumps blood throughout the body

Atria

Receives blood

Ventricles

Pumps blood to the rest of the body

Valves

Prevents blood from flowing backwards

What is in blood?

Plasma, RBC, WBC, platelets

What are the different kinds of blood types?

A, b, ab, o

Arteries

Carry blood away from the heart

Veins

Carry blood towards heart

Capillaries

Exchange materials (nutrients, oxygen, carbon dioxide) between blood and body cells

Respiratory system

Brings in oxygen which is needed for cellular respiration and gets rid of carbon dioxide made by cellular respiration

Urine

Excess water, salts, and urea (toxic substance that comes from the break down of protein)

Kidney

Separates needed materials from not needed materials

Pharynx

Throat

Carynx

Voice box

Wind pipe (frachea)

Connects to bronchi

Trachea

Filter oxygen again before it reaches the lungs. Celia and mucus help to clean oxygen

Bronchi

Takes that lead to lungs

Lungs

Made up of tiny air sacs called alveoli. Capillaries surround each alveoli and exchange oxygen and carbon dioxide

Skeletal system functions

-Provide shape and support


-helps you move


-protects organs


-produces red blood cells


-stores minerals: calcium

Parts of skeletal system

Bones, cartilage, vertebrae, joints, tendon, ligament

Muscular system

Keeps the heart beating and moves the body

Skeletal muscle

Voluntary muscle that provides the force that moves your body

Tendons

Attach muscles to bones

Ligaments

Attach bones to bones

Smooth muscles

Involuntary muscle that control movement inside the body

Cardiac muscle

Involuntary muscle that controls the heart beat

Digestive system

Breaks down food into nutrients that diffuse across cell membranes. Eliminates undigested food from body

When does digestion begin?

When you see/smell food

Mechanical digestion

Physically breaking down food


Ex- chewing

Chemical digestion

Using chemicals to break down food

Small intestines

Most chemical digestion occurs here.

Helper organs and their purposes

Liver- produces bile (enzyme that digests fat). Bile gets stored in the gall bladder and is secreted into the small intestine

Pancreas

Produces many enzymes that secrete into intestines

Large intestine

Water gets reabsorbed and undigested material is eliminated
