science- movement,breathing and respiration

movement, brathing and respiration booklet flashcards

what are the five groups of animals

fish, amphibian, reptiles, birds and mammals.

joint

when 2 or more bones meet allowing movement when 2 or more bones meet allowing movement

what do muscles do

they allow the bones to move by contracting and relaxing

what do bones do

they provide support to the body

tendon

attaches muscle to bone. Doesn’t stretch

how many bones does an adult have

206

what are the 2 types of tissue that a bone is made of

living and non living

define non living tissue

hard material that supports the weight of the body and is pulled by the muscles to cause movement.

define living tissue

where the body makes blood cells, it is called bone marrow. red blood cells carry oxygen around the body and white blood cells fight diseases

what would happen if 2 bones moved against each other

they would wear away

what do ligaments do

join 2 bones and can stretch.

name the 3 types of muscle

cardiac muscle, skeletal muscle and smooth muscle

cardiac muscle

the heart

smooth muscle

intestines and oesophagus have walls that are made from layers of muscle. these muscles allow the food to be churned and pushed through the digestive system

skeletal muscle

pull upon bones and cause movements of the organism in vertebrates

word equation for respiration

sugar+oxygen>carbon dioxide+water

rib muscle

allow the rib to move. increases the volume of thoracic activity

rib

protects lungs and provides sctructure

trachea

allows air to travel from mouth to lungs

diaphragm

contracts and flattens when we breath in

journey of air from outsde to inside our body

atmosphere> nasal passages> larnyx> trachea> bronchus> bronchioles> alveoli

alveoli

singular form of alveolus. each of your lungs contains millions of alvioli and they help diffuse carbon dioxide into the blood.

gaseus exchange

he movement of oxygen from the alveoli the the capillary and the movement of carbon dioxide from the calillerary into the alveoli

where does respiration happen

mitochondria

what does respiration do

provides energy

what respires

all living cells

hinge joint

A joint that moves simply, like a door opening and closing. Knees, elbows

ball and socket joint

Allows more movement in more directions. Shoulder.
