Diffusion
What is the process where molecules move from an area of higher concentration to an area of lower concentration
Diffusion
What is the primary function of respiration in living organisms?
To produce energy
This process is the result of air rushing into the lungs
Inhalation
This process occurs in the mitochondria of cells, often called the__________ of the cell.
"powerhouse"
Aerobic
air
In diffusion, what factor speeds up the movement
Temperature,Concentration,Pressure
What is the name of the process in which oxygen is used to break down glucose and produce ATP?
Aerobic respiration?
What are the tiny hairs that move back and forth along the trachea called?
Cilia
How do the left and right lungs differ?
The left lung is smaller than the right lung to accommodate the heart.
Pulmo
Lungs
How does surface area affect the rate of diffusion?
The larger the surface area, the faster the rate of diffusion.
Where does respiration happen?
Mitochondria
During inhalation what does the diaphragm do?
Contracts
The average adult lung can hold about _______ liters of air
6
Bronchi
windpipe
How does the diffusion of oxygen in the alveoli of the lungs differ between a person at sea level and a person at high altitude, and why?
Diffusion is slower at high altitude because the lower atmospheric pressure reduces the concentration gradient of oxygen between the alveoli and the blood
Choose an animal who respires the most:
Elephant
Hummingbird
Dinosaurs
Godzilla
the alveoli/air sacs
This pulls down and causes air to rush into the chest cavity
Diaphragm
_______ lungs have a unique structure that allows for more efficient gas exchange.
Bird
Intercostal muscle
inter-between,costa- ribs
Name 2 examples for diffusion of solids
1. Alloy Formation: When metals like copper and nickel are heated and pressed together, their atoms slowly diffuse into each other, forming a homogeneous alloy. This process is used in making coins and industrial materials.
2.Chalk
During intense exercise, why does your body switch to anaerobic respiration, and what is the byproduct of this process?
During intense exercise, the body switches to anaerobic respiration because oxygen cannot be supplied fast enough to the muscles. The byproduct of this process is lactic acid.
Intercostal muscles ,how do they work when you inhale and exhale
External contracts when you inhale
Internal contracts when you exhale
Some reptiles, like ____________, have a unique respiratory system that allows them to control their oxygen consumption, enabling them to hold their breath for long periods while submerged.
crocodiles
Cilia- meaning from Latin
from Latin cilium, meaning "eyelash.
