7.02 Respiratory and Circulatory Flashcards
The respiratory and circulatory systems work together to carry O2 through the body and to remove CO2 from the cells. T or F

Mucus and the hair in your nose are important why?
The mucus and the hair capture dust particles and any other substance other than O2.
The important organs in the respiratory system:
Nose Pharynx Larynx Trachea Lungs Bronchi Alveoli Diaphragm
Pharynx:
a cavity in the back of the mouth in which air and food travel next as it enters the nose/mouth.
Larynx:
two layered elastic folds between the pharynx and the trachea that produce sound as the air moving through the larynx vibrates.
Trachea:
a pipe which air moves in after the pharynx. The trachea has a thin layer of tissue on the top called the epiglottis. This tissue only lets air through and pushes the four that gets in the trachea. Then, tissues in the trachea remove dust particles.
Lungs and Bronchi:
air moves to the bronchus(2) each one takes air to the lungs where millions of bronchi take air in many paths .
Alveoli:
bronchioles divide in more sacs called the alveoli.
Diaphragm:
a thin layer of muscle that contracts when inhaling, and releases when exhaled.
Septum:
a wall that separates the left side of the heart to the right side.
The upper chambers of the heart is called what?
The upper chambers of the heart is called what?
The lower chambers of the heart is called what?
ventricles
Pulmonary circulation:
Systemic circulation:
The path of circulation between the heart and lungs.
The path of circulation between the heart and the rest of the body.
Red blood cells are formed:
in the red marrow . They contain large amounts of hemoglobin , a protein that binds to oxygen as it diffuses into the cells.
White Blood Cells:
help build immune and antibodies.
