Biology Unit 8
Axon Neuron
- single thread - transmits signal from cell body
What takes place through the tissues of the alveoli?
-Blood going to cells receives O 2 -Blood coming from the cells releases CO 2
Pectoral Girdle
-arms -scapulae
Dendrite Neuron
-branching "tree-like" structure -receives signals
How do nerve signals pass through a synapse?
-by chemical transmitters -by acetylcholine
erythrocytes
-carries CO2 -devoid of nucleus
leukocytes
-disease protection -phagocytosis
Pelvic girdle
-ilium -sacrum -ischium
