Respiration is the process by which __________ absorb oxygen and eliminate carbon dioxide.
bronchioles |
|
diaphragms |
|
capillaries |
|
blood cells |
The respiratory system manages respiration which is the process by which blood cells absorb oxygen and eliminate carbon dioxide.
The brain and spinal cord make up the __________ nervous system.
peripheral |
|
somatic |
|
autonomic |
|
central |
The nervous system consists of the brain and spinal cord (central nervous system) and the peripheral nervous system which is the network of nerve cells (neurons) that collect and distribute signals from the central nervous system throughout the body.
The gravitational interaction of Earth and the Moon is responsible for which of these?
the northern lights |
|
seasons |
|
tides |
|
day and night cycle |
Tides are caused by the gravitational interaction of Earth and the Moon.
Materials like metals that transfer heat efficiently are called:
insulators |
|
refractors |
|
reflectors |
|
conductors |
Heat is always transferred from warmer to cooler environments and conduction is the simplest way this transfer can occur. It is accomplished through direct contact between materials and materials like metals that transfer heat efficiently are called conductors while those that conduct heat poorly, such as plastic, are called insulators.
The respiratory and circulatory systems are similar in that they:
deoxygenate blood |
|
add carbon dioxide |
|
transport oxygen |
|
transport nutrients |
Like the respiratory system, the circulatory system serves to transport oxygen throughout the body while removing carbon dioxide. In addition, the circulatory system transports nutrients from the digestive system.
